Introduction

This LSU AgCenter Plant Disease Management Guide is revised as needed. The most important

or more prevalent diseases of the more common or important plants are included in this edition. The

suggestions for disease management are based on the best information available. The management

program, in general, is based on research conducted by Louisiana State University Agricultural Center

personnel in its Louisiana Agricultural Experiment Station, in cooperation with the U.S. Department of

Agriculture. In some cases, research results and plant disease guides from nearby states were used as a

basis for the management measures suggested.

Many fungicides are sold for the control of plant diseases, but because of space limitations, only

a few are listed. Reference to commercial products or trade names is made with the understanding

that no discrimination is intended and no endorsement of particular products by the Louisiana State

University Agricultural Center is implied. Always use pesticides safely. Read the label and follow safety

precautions. Do not eat or smoke while applying pesticides. Pesticides should be stored in their original

containers and out of the reach of children, pets or livestock.

LSU AgCenter 1 2013 Plant Disease Management Guide

The Safe Use of Pesticides

General Safety Instructions:

Know the pest.

Use pesticides only when needed.

Always ask the advice of an authority on problems with pests and pesticides.

Use only the recommended pesticide for the problem.

Know how effective the pesticide is and any hazards it might present.

Read the label – all of it, even the small print.

Commercial pest control operators, farmers and other applicators of large quantities ofpesticides or organophosphorus pesticides should contact their physicians at the beginning ofthe season, before using these materials, and have a blood test. At that time, the person(s)should inform the physician of the types of pesticides he or she will be using. A goodunderstanding should be established between the employer, the applicator and the physicianregarding the availability of the physician's services and certain standard charges for suchservices. While discussing the pesticides to be used, be sure your physician has a current list ofphone numbers for the official Poison Information Centers in case he or she is not familiar withall the types of pesticides and their antidotes, as well as signs and symptoms of pesticidepoisoning.

Know what you are to do in the event of an accident. PLAN AHEAD. Call your physicianimmediately if an accident occurs.

Have your physician's phone number posted by your phone. In an emergency, time is extremelyimportant.

Consider wearing a Medic‐Alert emblem.

Take time to explain the safe use of pesticides to employees. Make sure they understand.

Check your application equipment for leaks and clogged lines, nozzles and strainers.

Calibrate your equipment frequently for proper output. Use water or other inert materials.

Check respirator for cleanliness. Make sure it has a clean filter and fits properly.

Check gloves and other protective clothing for holes and cleanliness before each use.

Make sure plenty of clean water, soap, towels and a clean change of clothing are available.

Do not permit delivery of pesticides unless a responsible representative is on hand to receiveand properly store them.

Make sure humans have been warned and livestock and pets that may be exposed have beenremoved from the area to be treated.

Cover food and water containers.

Check the label to make sure the time intervals between date of application and harvest,slaughter or milking will comply with those given on the label.

The LSU AgCenter’s Plant Diagnostic Center

Instructions for Collection, Preparation and Shipping of Plant Samples

Accurate and rapid diagnosis depends on the quality and quantity of the sample submitted for diagnosis. No one method of preparation of plant materials for shipping will ensure their satisfactory arrival in the laboratory. Following the suggestions given below will help to ensure specimens are received in as good a condition as possible, however.

Specimens completely desiccated or in advanced states of decay and those that arrive without supporting information and diagnostic fees will have to be discarded. This represents time and labor wasted for the sender and personnel at the LSU AgCenter. Note: Findings reported are inevitably based on examination of the material submitted. Some diagnoses require intensive studies. Because the time devoted to individual specimens must be limited, reports, while reflecting considered opinion and best judgment, may not always be statements of established fact.

To get the best possible results, follow these instructions:

General Guidelines for Submitting Plant Samples for Routine Diagnosis

Please consult the following guidelines before collecting, packing and submitting the

samples.

Plan to collect and submit samples early in the week.

Pack samples properly. (See ”Packaging and Mailing.”)

Collect specimens representing a range of symptoms.

Collect all parts of the plant that show symptoms.

Collect specimens before applying any chemicals.

Submit generous amounts of plant material.

Samples must be accompanied by a completed Sample Submission Form. Samples

without the Sample Submission Form will not be diagnosed. Place Sample Submission

Form in a plastic bag if the sample contains roots, soil or perishable tissue.

Samples must be accompanied by payment of the appropriate diagnostic fees. (Samples

without diagnostic fees may not be diagnosed.)

Write correct mailing address on the package.

Specimens from different plant species should be packed separately.


Out‐of‐state samples must be accompanied by the PPQ 526 permit for interstate

movement of the plants/plant material. (Contact Dr. Raghuwinder Singh at

[email protected] or 225‐578‐4562 or the center at 225‐578‐1464 for the

permit.)

For Plant Disease Diagnosis

Plants showing wilting, yellowing or general decline:

1. Send whole plants, including roots, if practical. Be sure to send plants showing earlystages of disease.

2. Dig up carefully. (Don't pull up!)3. Send sample of soil and feeder roots in plastic bag. Seal to avoid loss of moisture.

Cankers:

1. Select specimens from recent infestations. Send entire cankered portion, if possible,with some of the healthy wood above and below the canker.

2. Branches and twigs that have been dead for several months are useless foridentification.

Leaf spots/blights/scorch:

1. Collect several (15‐20) leaves showing early and late stages of infestation.2. For scorch symptoms, send the affected twig/branch with leaves attached. Cut several

foot‐long twigs that show leaf scorch symptoms, wrap these in dry paper towels andpack in a plastic bag.

3. For spots or blight, wrap leaves in dry paper towels and then pack those in plastic bags.4. It usually is not possible to diagnose marginal burning or other injury symptoms on

leaves.

Fleshy organs:

1. Rots of fleshy fruits and vegetables need special attention. Do not send those inadvanced stages of decay.

2. Select fresh specimens showing early symptoms.3. Place specimens in a plastic bag with dry paper towels. Do not add extra moisture.

Fleshy vegetables and fruit specimens should be wrapped separately. Keep cool untilshipped.


Homeowner turfgrass samples:

1. Collect turf samples with early and advanced stages of disease development.

Completely dead turf grass seldom generates an accurate diagnosis.

2. Collect turf samples from transition zone between healthy and diseased turfgrass so it

contains both healthy and affected turf.

3. Collect a 6‐inch‐by‐6‐inch section of affected turf with soil intact.

4. Wrap the sample in newspaper or aluminum foil.

5. Place sample in a sturdy cardboard box and pack securely.

6. Do not add water to the sample.

7. Place the completed Sample Submission Form and diagnostic fee in a plastic bag and

send it with the sample.

8. Ship turf samples to the diagnosticcCenter immediately after collection.

For Nematode Diagnosis/Identification

1. Late summer and fall are the best times to take nematode samples.2. Nematode samples require at least one pint of soil from approximately 20 random soil

probes. Mix soil together and mail in plastic bag placed inside an LSU AgCenter soilsampling box (available through LSU AgCenter parish offices and other locations).

3. Sample must be accompanied by nematode assay form with required information.4. Protect sample from heat and light.

For Insect Pest or Mite Diagnosis/Identification

1. Collect damaged plant parts, such as leaves or twigs, and wrap those in dry papertowels. Place the wrapped tissue in plastic bags.

2. If root samples are submitted, pack the damaged roots, with soil intact, in plastic bags.3. Submit insect specimens in glass vials containing ethanol. Label the vials with the

collection information, including the site, host, date and collector’s name.4. Complete the Sample Submission Form for each sample/vial specimen submitted for

diagnosis.

For Weed Identification

1. Send the entire plant for identification. Leaves alone may not be sufficient for anaccurate identification.

2. Dig up carefully. (Don't pull up!)3. Wrap roots in a plastic bag and the rest of the plant in dry paper towels and pack the

entire plant in a plastic bag.4. High‐quality images of the plant where it was growing may aid in identification.


Packaging and Mailing

1. Do not add water to samples.2. Wrap plant tissue such as leaves or twigs in dry paper towels and place in plastic bags.3. Pack foliage and roots collected from the same plant in separate plastic bags.4. Wrap fruit samples in dry paper towels.5. Pack samples in a sturdy cardboard box. Wrap the package in heavy paper. Attach

envelope containing Sample Submission Form to outside of package.6. Identify package with both outside and inside labels, and don't put inside label in

contact with moisture.7. Address package to: LSU AgCenter Plant Diagnostic Center, 302 Life Sciences Building,

LSU AgCenter/LSU Campus, Baton Rouge, LA 70803.8. Mail packages to arrive on weekdays (Monday through Friday) rather than on the

weekend.

Remember: The better the specimen, the more accurate the diagnosis.

Rapid Turfgrass Diagnostics

The rapid turfgrass diagnostics service is intended for commercial golf courses, athletic fields

and landscapes. It always is preferred to check with the diagnostician before collecting and

submitting turfgrass samples for rapid turfgrass diagnosis.

Turfgrass Sample Collection

1. Collect turf samples with early and advanced stages of disease development.

2. Collect turf samples from transition zone between healthy and diseased turfgrass so the

samples contain both healthy and affected turf.

3. Collect two samples from each problem area. Samples can be either ”cup cutter”

samples or a sample at least 6 inches by 6 inches.

4. Completely dead turfgrass seldom generates an accurate diagnosis.

Turfgrass Sample Packaging

1. Wrap samples in newspaper or aluminum foil.

2. Place samples in a sturdy cardboard box and pack securely.

3. Do not add water to the samples.

4. Ship samples immediately to the clinic after collection.

5. Do not forget to include the completed Rapid Turfgrass Sample Submission Form with

the samples.


6. Samples without the appropriate Sample Submission Form(s) and diagnostic fee(s) will

not be processed.

7. The rapid turfgrass diagnostic service is provided for a charge of $75 for in‐state and

$100 for out‐of‐state samples.

8. Make checks for fees payable to “LSU AgCenter PDC.”

Turfgrass Sample Submission

1. Ship samples to correct mailing address.

2. Ship samples early in the week.

3. Samples should be delivered overnight (preferably via courier services).

4. Samples will not be received on Saturdays, Sundays and other LSU AgCenter holidays.

FieldCropsCorn

Disease

Charcoal Rot (Macrophomina phaseolina)

Symptoms: Injury from this disease usually does not become evident until plants approach maturity. Diseased plants exhibit poorly developed ears, premature ripening, lodging and drying of the stalk. Stalks are soft and discolored at the base, and the pith becomes shredded. Source of Inoculum: This fungus survives in old plant debris or in the soil. Control: Rotate crops. Bury stubble. Maintain balanced potassium/nitrogen rates.

Common Rust (Puccinia sorghi)

Symptoms: Common rust can be recognized by small oval to elongated pustules, which are at first cinnamon‐brown and then become brownish‐black as the corn matures. The pustules may appear on any aboveground part of the plant but are most abundant on the leaves – scattered over both surfaces. Source of Inoculum: Spores usually are windblown from the south. An alternate host is the wood sorrel (Oxalis sp.). Control: Most hybrids are tolerant to this disease. Always use the recommended hybrids for your area.

Fusarium Stalk Rot (Fusarium sp.)

Symptoms: Leaves of infected plants become grayish‐green as plants approach maturity. Softening and discoloration of the exterior of lower internodes occur. When stalks are affected with stalk rot, they split and generally will show a reddish discoloration of the diseased area. Source of Inoculum: This fungus lives in old stubble or in the soil. Control: Practice crop rotation. Plow crop residue under. Make sure adequate potassium is applied with high nitrogen rates.

Gray Leaf Spot (Cercospora zeae‐maydis)

Symptoms: The early lesions produced on the corn leaves by Cercospora zeae‐maydisare yellow to tan in color and look similar to those produced by other diseases except they have a faint watery halo that can be seen when held up to the light. After about two weeks, the lesions appear tan to brown and rectangular shaped, bordered by the veins of the leaf. When fully expanded, individual lesions may be 3 to 4 inches long and 1/16 to 1/8 inch wide, depending on the distance between veins. If several infections occur near each other on the same leaf, however, a broader lesion will result. Source of Inoculum: The fungus causing gray leaf spot overwinters in and on corn debris left above and on the soil surface. Control: Hybrids are available with moderate resistance. Crop rotation and clean plowing are effective in reducing the level of surviving fungus in fields.

Northern Corn Leaf Blight (Exserohilum tursicum)

Symptoms: Leaves of infected plants have a few to numerous elongated (up to 1 inch by 6 inches) leaf spots that are tan but reveal black spore growth at maturity. Source of Inoculum: Carried on the seed and in old plant refuse, spores also are readily windborne. Control: Disease resistance is available. The hybrids should also be ones recommended for your area.


FieldCropsCorn

Disease

Smut (Ustilago maydis)

Symptoms: All aboveground parts of the plant are susceptible, particularly the young, actively growing embryonic corn tissue. Symptoms are easily recognized. Galls are first covered with a glistening greenish‐white to silvery‐white membrane. Except for galls on leaves, the interiors of the galls soon darkes, with the membrane rupturing to expose millions of greasy to powdery, sooty spores known as chlamydospores or teliospores. Galls on leaves seldom develop beyond pea‐size, becoming hard and dry without rupturing. Early infection may kill young plants, but not often. Source of Inoculum: The teliospores of this fungus overwinter on the soil surface. Control: Use hybrids recommended for your area. Most have adequate resistance.

Southern Leaf Blight (Bipolaris maydis = Helminthosporium maydis)

Symptoms: Leaves of infected plants have numerous elongated spots between the veins. The spots are buff to reddish‐brown. Source of Inoculum: Carried on the seed and in old plant refuse, spores also are readily windborne. Control: Use only seed produced by normal tasseling (N). The hybrids also should be ones recommended for your area.

Southern Rust (Puccinia polysora)

Symptoms: Southern rust is recognized by small circular to oval pustules, which are light cinnamon‐brown. The pustules may appear on leaves and sheaths but are most abundant on the leaves. Source of Inoculum: Spores are windblown from the south. No alternate host is known. Control: Use hybrids tolerant to this disease.

FieldCropsCotton

Disease

Fusarium wilt (Fusarium sp.)

Symptoms: Plants usually are stunted and may fruit early. Leaves may turn yellow, wilt and drop. Brown to dark brown discoloration occurs on woody tissue just beneath the bark. It is more severe on sandy soils, during hot weather and when root‐knot or reniform nematodes are present. (See also root‐knot nematodes below.) Source of Inoculum: Fungus lives indefinitely in soil. Nematodes, likewise, live from year to year in the soil. Control: Use of tolerant varieties. Most recommended varieties exhibit tolerance to Fusarium wilt. Under more severe conditions, use recommended nematicides. (Refer to table on nematode control in field crops.)

Verticillium wilt (Verticillium sp.)

Symptoms: Leaf margins and between veins have pale yellow markings. Severely affected plants shed the young bolls. Light brown discoloration occurs in the interior woody tissue of the stem with little to no discoloration just beneath the bark. Occurs in cool weather with or without nematodes. Source of Inoculum: Fungus lives indefinitely in the soil. Control: Rotate with soybeans, sorghum or small grains.

Root‐knot nematodes1 (Meloidogyne sp.)

Symptoms: Root systems are knotted or galled. Plants are stunted, slow growing and low yielding. Usually associated with a high incidence of Fusarium wilt. It is most severe on sandy soils. (See Fusarium wilt above.) Source of Inoculum: Root‐knot nematodes live from year to year in the soil as eggs or larvae. Control: Use resistant variety. Apply nematicide. Refer to table on nematode control in field crops.

Reniform nematodes1 (Rotylenchulus sp.)

Symptoms: These nematodes cause severe stunting, reduced boll set and tight, locked bolls. Root systems are restricted but not knotted. May be found in mixed to heavy soil. Source of Inoculum: Reniform nematodes live from year to year in the soil. Control: Apply nematicides. Refer to table on nematode control in field crops. There are no resistant varieties.

Seedling diseases1 (Rhizoctonia spp., Pythium spp., Fusarium spp. and other fungi)

Symptoms: Loss before emergence is characterized by a rot of the seed or seedling. After emergence, affected seedlings have dark lesions on the stem, often girdling the stem and extending downward to and including the root system. Older plants have reddish‐brown, sunken lesions near the soil line. Source of Inoculum: Some of the organisms causing seed rot and seedling diseases may be carried on the seed coat while others live indefinitely in the soil. Control: Use only high‐quality seed. Plant seed only when soil temperatures at a 4‐inch depth reach 68 degrees F for three to four days. Plant only treated seed. Prepare a good seedbed. Plant at proper depth for soil type and weather conditions. Use a recommended soil fungicide or fungicide/nematicide combination. See table on fungicides.

Boll Rots (many fungi and bacteria)

Symptoms: There is a wide range of symptoms since there are many organisms involved and many stages of boll development when damage may occur. Discolored, sunken areas may develop on the boll surface. Seed and fiber may be damaged without surface lesions on the boll. Fiber may be stained. Source of Inoculum: Organisms causing boll rots may be carried over in the soil, on crop debris or on the seed coat. Control: Avoid practices that promote excessively rank growth. Control insects during boll development. Plant growth regulators may be helpful in reducing the incidence of boll rot when used in areas where rank growth usually occurs.

1 Research indicates the use of pesticide mixtures that contain chemicals with fungicidal, insecticidal and nematicidal activity increases the yield of early planted cotton. The mechanism(s) by which the pesticide mixture increases yields in early planted cotton has not been entirely explained.

FieldCropsGrainSorghum

Disease

Anthracnose (Colletotrichum graminicola)

Symptoms: Infection first appears on the leaves as small tan to reddish‐purple circular spots, which later enlarge and may unite to involve large areas of the leaf. Later, the centers of the leaf spots fade to grayish‐tan. Infection on the leaf midrib is strikingly discolored. The leaf anthracnose organism also causes a stalk rot. The stalk rot phase of this disease usually follows the anthracnose stage on the leaves. The fungus enters the stalk directly through the rind or a wound in the rind and spreads to the interior of the plant. The lesions that form on the outside of diseased stalks usually have reddish to purplish margins and whitish centers. When infected stalks are split, the pith is red or purplish‐red. Diseased stalks frequently break over at the base or at a point one or more joints above the ground. Poor head and seed development results from severe infections. Control: Plant fungicide‐treated seed. Practice at least a three‐year rotation with other crops such as wheat, oats, barley, cotton and soybeans. Turn under old crop stubble after harvest. Fungicides are available.

Charcoal Rot (Macrophomina phaseolina)

Symptoms: Injury from this disease usually does not become evident until the plant approaches maturity. Affected plants show poorly developed heads, light kernels, premature ripening, drying of the stalk and lodging. Diseased stalks are soft and discolored at the base, and the pith becomes shredded. Control: Irrigate where possible.

Downy Mildew (Sclerospora sp.)

Symptoms: Systemically diseased seedlings are yellowed, stunted and frequently have a white downy growth on the underside of the yellowed leaves. Later, the plants have green‐and‐white‐striped or mottled leaves. These plants may fail to head, produce sterile heads or form partially affected heads. Diseased plants usually are found in poorly drained areas. Control: Follow cultural practices outlined for anthracnose.

Head Blight (Fusarium moniliforme Curvularia sp. Cladosporium sp.)

Symptoms: Head blight is caused by several fungal organisms that infect plants from flowering to maturity, depending on high moisture conditions. (Fusarium head blight, the most destructive of sorghum head blights, occurs most commonly along the Gulf Coast production areas). The fungus is capable of infecting sorghum heads at and soon after blooming. Panicles and rachis branches are infected first, followed by infection of stalk tissue at and immediately below the head. Weak neck and stalk lodging may follow. Control: While no hybrids are immune, some sustain less damage and less economic loss.

Gray Leaf Spot (Cercospora sorghi)

Symptoms: Small circular to elliptical dark purple or red spots appear on leaf surface.Later, leaf center becomes tan or brown, and spots elongate with gray spore masses covering the spots. Other hosts include corn, Johnson grass and cultivated grasses. Control: Most varieties have adequate tolerance to this disease.


FieldCropsGrainSorghum

Disease

Zonate Leaf Spot (Gloeocercospora sorghi)

Symptoms: On the leaves, circular, reddish‐purple bands alternate with tan or straw‐colored areas that give a concentric or zonate pattern with irregular borders. Spots may occur along the margins of leaves or on other plant parts. Control: Recommended varieties have some tolerance to the disease. Crop rotation and clean cultivation help.

FieldCropsOats

Disease

Crown Rust (Puccinia coronata)

Symptoms: Small, scattered, oval or oblong, orange‐yellow pustules develop principally on the leaves. Similar pustules may occur on the leaf sheaths, stems (culms) and panicles. The pustules soon break open to release a dusty mass of golden spores. Source of Inoculum: The source of spores that cause the primary infection during the fall in Louisiana is not known. Disease spreads by windborne spores. Control: Plant recommended varieties that have resistance to the prevalent races of the rust fungus.

Stem Rust (Puccinia graminis avenae)

Symptoms: Elongated, reddish‐brown pustules occur on the stem, leaf sheaths, leaf blades and glumes. Pustules rupture the epidermis to expose a powdery, reddish‐brown mass of spores. Fragments of epidermis adhere to sides and ends of pustules to give them a ragged appearance. Source of Inoculum: The source of spores that cause the primary infection is not known. Stem rush has an alternate host, European or common barberry (Berberis vulgaris). Control: Plant recommended varieties that have resistance to the prevalent races of the rust fungus.

Yellow Dwarf (Barley Yellow Dwarf Virus)

Symptoms: The most typical symptom is leaf discoloration. Affected oat plants may have leaves that are dull yellow to brilliant red. The red leaf color is not always present, however. Plants infected late in the season may be stunted and have reduced yields. Source of Inoculum: The virus may live in perennial grasses along fence rows and roadways. Aphids spread it. Control: No practical control measure is available.

Leaf Blotch (Drechslera avenacea = Helminthosporium avenaceum)

Symptoms: This fungus can cause seedling disease. On older plants the disease appears as reddish‐brown, round to oval spots, primarily on leaves and leaf sheaths but sometimes on stems and floret parts. Spots have irregular margins and frequently have sunken centers. Long linear blotches result from merging of spots. Severely infected leaves turn yellow and die. Source of Inoculum: The fungus can live on seed and plant debris. Control: Rotate oat crops on different fields.

Disease

Blast (Pyricularia grisea)

Symptoms: Leaf lesions are spindle‐shaped and elongated with brown borders and grayish centers. A brownish lesion on the internode at the base of the panicle causes “blasting” of heads followed by breaking over of the head to produce the “rottenneck” symptoms. Source of Inoculum: Fungus may overwinter on diseased straw and stubble, or in some cases it may be carried on infested or infected seed. Source of inoculum for early infection has not been satisfactorily worked out. It spreads in the field by means of airborne spores. Control: For leaf stages of the disease, maintain proper flood level. Infection levels tend to be less severe where floodwater is maintained at adequate but not excessive depths. Plant varieties resistant to prevalent races of the fungus. (See variety list.) Avoid excessive rates of nitrogen (Nitrogen amounts vary with cropping history, soil type, varieties, etc.). The use of fungicides will be helpful in the management of blast. Fungicide timing is critical for effective control.

Sheath Blight (Rhizoctonia solani)

Symptoms: Large spots with cream‐colored centers and broad, dark reddish‐brown borders appear on sheath, usually beginning near the water line. Alternating wavelike tan and brown bands can extend up the sheath and may include the flag leaf. The wavelike band pattern may extend out on part or the entire leaf surface. Source of Inoculum: Fungus is soilborne and persists as sclerotia or mycelia on straw and stubble of rice and grasses. Weed hosts may serve as sources of inoculum. Control: Thick stands and excessive nitrogen applications tend to favor disease development. Some varieties are less susceptible than others. (See variety list.) Fungicides may be necessary to suppress disease development. Fungicide‐resistant populations exist in some fields.

Brown Leaf Spot (Bipolaris oryzae)

Symptoms: Dark reddish‐brown spots are somewhat circular or oval to slightly elongated. Mature spots have gray centers. Spots usually associated with low nitrogen or maturity of the plant. Spots also may occur on hulls and kernels with a dark brown fungus sometimes present on kernels. Source of Inoculum: The fungus is seedborne and also may live from one crop to the next on infected rice straw and stubble. It is spread by airborne spores. Control: Maintain good growing conditions through fertilization, land leveling, soil preparation and other cultural practices.

Narrow Brown Leaf Spot (Cercospora janseana)

Symptoms: Leaf spots are light reddish‐brown to brown, long and narrow. Reddish‐brown discoloration of the sheath may occur when disease pressure is severe. Disease usually occurs after heading. Source of Inoculum: The fungus persists on crop residue and on red rice. Control: Varietal resistance offers the best approach to control. (See variety list.) Fungicides may control narrow brown leaf spot.

Seed and Seedling Diseases Water molds

(Achlya sp. Pythium sp.)

Seedling Blight (Several fungi)

Symptoms: Light to dark brown discoloration on soil surface around seed after water is removed. Usually have fluffy fungal growth around seed before water is removed. Source of Inoculum: These fungi persist in the soil on organic matter. Control: Removing water after seeding will reduce losses. Seeding into clear water reduces the incidence of water mold. Symptoms: Young plants have roots and lower stem affected, often resulting in death of the plant. Dark lesion at the junction of seed and root. Source of Inoculum: May be seed‐borne or soil‐borne.


FieldCropsRice

Disease

Stem Rot (Sclerotium oryzae)

Symptoms: Black, discolored areas on leaf sheath near surface of water. Later, small black seedlike sclerotia develop inside leaf sheath and still later inside the stem. Stalks may break over and lodge. Source of Inoculum: Fungus persists in the sclerotial stage in soil and on diseased straw and stubble. Control: Applications of potassium to the soil may reduce the severity of the disease in some instances.

Straighthead (Physiological Disorder)

Symptoms: Rice heads remain upright at maturity because of lack of grain formation.Hulls usually are crescent or “parrot beak” shaped. Source of Inoculum: No organism involved. Control: Drain water from field just prior to jointing stage of growth. Leave water off until cracks form in the mud. Then flood again. Some varieties are moderately resistant to this disorder. (See variety list.)

Disease

Seedling Disease (Rhizoctonia solani, Phytophthora, Pythium, etc.)

Symptoms: Seed decay and post‐emergence “damping off.” Roots and basal portion of stem may deteriorate or be killed. Source of Inoculum: Most of these organisms are soil‐borne and persist in crop residue. Control: Seed treatment.

Charcoal Rot (Macrophomina sp.)

Symptoms: Seedling infections result in a discoloration at the soil line. Seedlings may die if hot, dry conditions exist, or they may survive in wet weather with disease symptoms reappearing during hot, dry spells. In older plants, a light brown discoloration of internal tissue occurs. Plants turn yellow and “mature very early.” Below the epidermis, at the soil line, small black bodies appear, giving the tissue a grayish‐black “charcoal” appearance. Control: Avoid excessive seeding rates. Rotate with nonhost crops. Maintaining good fertility will reduce the incidence of this disease. Avoid plant stress as much as possible by using good management practices.

Phytophthora Root Rot (Phytophthora sp.)

Symptoms: Destroys roots and tender stems of infected seedlings, resulting in rapid death. Older plants turn yellow and leaves wilt. A brown discoloration develops in the stem. Source of Inoculum: Soil‐borne. Damage is most severe on heavy clay soils or on poorly drained soils. Control: Avoid planting susceptible varieties on poorly drained soils. Rotate.

Red Crown Rot (Black Root Rot) (Calonectria sp.)

Symptoms: First symptoms appear as an interveinal yellowing of the tops of individual plants, generally when plants are in the early pod stage. Later, interveinal tissue of leaves turns brown. That is followed by defoliation. On the stems, reddish‐orange fruiting structures appear at the soil surface and up to 3 inches above. Stem tissue appears reddish. Control: Research and field observations indicate there are differences in varieties, but exact ratings are difficult to achieve. Delay planting until later part of recommended planting time.

Southern Blight (Sclerotium sp.)

Symptoms: Scattered plants wilt suddenly and die. White mold appears at the base of the plant and girdles the stem. Tan to brown sclerotia (resting bodies) about the size of mustard seeds appear in the mold. Source of Inoculum: The fungus is soil‐borne and occurs widely in many soils. It is capable of persisting on almost any type of organic matter. Control: Losses to this disease usually are minimal and do not warrant control measures.

Aerial Blight (Rhizoctonia sp.)

Symptoms: The infected area typically involves the lower third of one or more of the three leaflets. The necrotic areas may vary in shape from circular to irregular with reddish‐brown margins. Leaf blight, leaf spots and defoliation are symptoms of the disease. Lesions may vary from reddish‐brown to brown or tan. Several leaflets may appear to be “glued together” with a cottony growth (fungus). Petioles, stems and young pods also are attacked. Source of Inoculum: Weed hosts, field trash and soil.


FieldCropsSoybeans

Disease

Control: Fall cultivation of stubble. Use good seedbed preparation and weed control. Research and field observations indicate there are differences in varieties. Use Quadris fungicide at first appearance of disease and conditions that favor disease development. See manfacturer’s label for suggested rates.

Brown Leaf Spot (Septoria sp.)

Symptoms: Angular brown to reddish‐brown spots appear first on lower leaves,causing yellowing and later defoliation. Symptoms usually are seen first on young plants during cool weather. Sizes of spots vary from a pinpoint to ¼ inch diameter. Source of Inoculum: The fungus overwinters in crop residue and on infected seed. Control: Plant disease‐free seed. Rotate. Bury crop residue deeply as soon as possible. Development of the disease is limited by warm weather.

Downy Mildew (Peronospora sp.)

Symptoms: Indefinite yellowish‐green areas on upper leaf surface. Grayish tufts of mold growth on lower leaf surface beneath chlorotic spots. Source of Inoculum: Overwinters in soil, on seed and in soybean residue. Control: Crop rotation. Use of disease‐free seed. Seed treatment reduces seedling infection.

Frogeye Spot (Cercospora sp.)

Symptoms: An eyespot type of lesion with a gray or light tan center and a narrow reddish‐brown border forms on the leaves. May cause premature defoliation. Source of Inoculum: Seed and airborne. Control: Use resistant varieties. Apply foliar fungicides.1

Purple Seed Stain (Cercospora sp.)

Symptoms: Pink or light purple to dark purple discoloration of seed. Cracks may occur in discolored areas. Reddish‐brown angular lesions, approximately 1/16 inch diameter, may occur on leaves, stems or pods late in the growing season. Source of Inoculum: Overwinters in crop residue and on infected seed. Control: Plant disease‐free seed. Treat seed with fungicides. Apply foliar fungicides.

Anthracnose (Colletotrichum sp.)

Symptoms: Symptoms appear as irregular brown areas most frequently on stems and pods. In advanced stages, affected tissues are covered with black fruiting bodies. The disease may cause serious losses, especially during rainy periods. Seed may fail to form or be wrinkled and moldy. Control: Plant disease‐free seed. Some benefit may be derived from seed treatment. Plow under crop residue. Apply foliar fungicides.1

Soybean Rust (Phykopsora pachyrhizi)

Symptoms: Rust pustules can be found on the underside of lower leaves when conditions are right for disease development. Pustules are tiny and raised and require at least a 15X hand lens to see the pustules. Control: Fungicides will control Asian soybean rust, but timing is critical.

Pod and stem blight (Diaporthe phaseolorum var. sojae = Phomopsis sojae)

Symptoms: Numerous small black fruiting bodies appear on the pods and stems of mature plants. Blight usually occurs in linear rows on the stem. Under favorable environmental conditions for the disease, it can be observed as a white mycelial growth on seed. Source of Inoculum: Fungus is seed‐borne and overwinters on diseased plant

Disease

tissue in the field.Control: Plant disease‐free seed. Some benefit may be derived from the seed treatment. Apply foliar fungicides.

Stem Canker (Diaporthe phaseolorum var. caulivora)

Symptoms: First symptom is the appearance of small reddish‐brown lesions on one or both cotyledons. Late in the season, dead plants are seen with dried attached leaves. Interveinal yellowing is evident on leaflets (similar to foliar symptoms of red crown rot). Infection usually starts as a small lesion at the base of a main‐stem node. Lesions enlarge rapidly to form a slightly sunken, reddish‐brown canker. Plants are brittle and break at the canker. Control: Use resistant varieties. Delay planting until later part of recommended planting time. Avoid stress. Maintain good fertility.

Virus or Virus‐like Disease Complex

Symptoms: Infected plants remain green, especially stems, beyond expected harvest date, with welling appearing at the nodes. Few pods are formed, and those that do form contain only one or two beans. A proliferation of buds may appear. Control: Some of the causal agents are carried over in infected seed. Do not save seed from infected fields.

Reniform Nematodes (Rotylenchulus reniformis)

Symptoms: Severely infected plants are stunted and may show chlorosis. Severeyield reduction may occur when nematode populations are relatively high. Control: Plant resistant varieties. Rotate with nonhost crops. Under extreme conditions, use nematicides.

Root Knot Nematodes (Meloidogyne incognita group)

Symptoms: Above‐ground symptoms are poor pod set with wilting and stunting in more‐or‐less circular patches on lighter soil types. Below‐ground symptoms are knots or galls on the roots. These swellings are a part of the root and do not “flick off” easily, as bacterial nodules do. Source of Inoculum: The nematode overwinters in the soil as eggs or larvae. Control: See varietal resistance table. Rotate with less susceptible crops. Under extreme conditions, use nematicide.

Soybean Cyst Nematodes (Heterodera glycines)

Symptoms: Stunting and various stages of yellowing occur in roughly circular spots. Symptoms vary, depending on nematode population, soil type and fertility and environmental conditions. Symptoms are most pronounced on sandy soil. Source of Inoculum: Nematodes overwinter in soil, primarily inside resistant cysts. They may be spread to new locations by any means that spread soil. Control: Practice two to four year rotation with cotton, corn or sorghum.

Other Nematodes Spiral Lance Ring Lesion Stubby‐root

Symptoms: Stunting, stand loss and reduced yields are associated with high populations of single or mixed populations of these nematodes. Symptoms will vary depending on nematode type and population levels. Control: Rotate with other crops. If populations are high at planting, a nematicide may be used.

FieldCropsSugarcane

Disease

Leaf Scald (Xanthomonas albilineans)

Symptoms: Leaves of young plants may show bleaching or yellowing. The characteristic symptom of leaf scald is the presence of one or more narrow, white “pencil lines” running longitudinally down the full length of the leaf blade into the sheath. Bands of dead tissue may develop along pencil lines starting at the leaf margin and expanding until the entire leaf is dead. Young shoots may be killed. Mature stalks may show leaf symptoms and develop side shoots with symptoms. Under severe disease conditions, entire plants may die. Drought stress may induce severe symptom expression. Source of Inoculum: The bacterium that causes leaf scald lives from year to year in infected plants. It is spread by the harvester and possibly by other cultivation practices that cause plant wounding. The disease can be spread aerially in windblown rain. Control: Varietal resistance is the best means of control. Only two varieties that are going out of production, LCP 85‐384 and Ho 95‐988, are highly resistant. HoCP 96‐540 exhibits moderate resistance. The other current varieties exhibit varying degrees of susceptibility, with HoCP 00‐950 being the most susceptible. Avoid planting seed cane from fields with diseased plants. Regular planting of healthy seed cane produced through tissue culture has kept the incidence of leaf scald low. The heat treatment used to control ratoon stunting disease is not effective against leaf scald.

Mosaic (Sorghum mosaic virus) (Sugarcane mosaic virus)

Symptoms: The mosaic pattern of irregular, interspersed, pale green, yellowishand green areas on leaves varies with cane variety, stage of growth, temperature and the strain of the virus involved. The mosaic symptom is most evident in the youngest emerging leaves. Source of Inoculum: The virus persists from year to year in infected plants. It is spread primarily by migrating aphids and also by planting infected seed cane. Control: Mosaic is controlled primarily with host plant resistance. Historically, mosaic was a major disease adversely affecting sugarcane production in Louisiana. Basic breeding and development of sources of resistance have greatly reduced the effects of this disease, however. Currently grown varieties have adequate levels of resistance to mosaic. Planting seed cane produced through tissue culture can help keep disease incidence low in susceptible varieties.

Ratoon Stunting (Leifsonia xyli subsp. xyli)

Symptoms: Ratoon stunting disease has no obvious external symptoms. Infected plants may be shorter but with little or no decrease in diameter of the stalk. Stunting severity is associated with adverse environmental conditions, particulary drought stress, and it is more severe in ratoon crops. Affected plants, when split, may or may not show a pinkish color in the growing point of young shoots and orange to brownish discoloration of vascular bundles at the nodes in the lower portion of mature stalks. Source of Inoculum: The bacterium lives from year to year in infected cane. It is spread by the cane harvester and by planting infected seed cane. Control: A healthy seed cane program is the primary method for control. Seed cane produced from tissue culture free of the disease is commercially available. Heat treatment of seed cane in hot water at 50 degrees Celsius (122 degrees Fahrenheit) for two hours can provide control of most ratoon stunting disease bacteria. A regular annual heat treatment program can provide good control. Monitoring of infection levels and the success of a healthy seed cane program can be provided by collecting stalk samples and having them tested at the LSU Ag Center’s Sugarcane Disease Detection Lab. The level of resistance varies among varieties. High levels of resistance are uncommon, so a healthy seed cane program is essential for successful control.


FieldCropsSugarcane

Disease

Red Rot (Glomerella tucumanensis)

Symptoms: Red rot adversely affects stand establishment by rotting planted seed cane. Splitting stalks dug up from portions of a row without living plants reveals red discoloration of the internode tissue and rotted nodes. Within the red areas, white spots, usually elongated at right angles to the long axis of the stalk, are indicative of red rot infection. Red rot is more severe when planted stalks are exposed to drought stress or waterlogging. Source of Inoculum: The fungal pathogen survives from season to season in infected cane tissue. Fungal inoculum is present on most planted stalks. Control: Plant multiple whole stalks and avoid planting heavily bored or physically damaged seed cane. Provide good drainage for planted seed cane. High levels of varietal resistance are uncommon, so cultural practices that minimize stress on planted seed cane are needed to minimize red rot damage.

Rust (Brown) (Puccinia melanocephala)

Symptoms: Small chlorotic areas appear on the leaves, at first as flecks. Later, the flecks elongate and become reddish‐brown. The spots continue to enlarge, with a slight yellow halo surrounding the lesions on some varieties. The lesions take on a pustular appearance on the undersurface of the leaf, and pustules erupt, releasing a reddish‐brown mass of spores. On susceptible varieties, heavily infected leaves dry out and die prematurely. Source of Inoculum: Rust survives the winter in living green leaf tissue – usually in southern areas of the industry. Spores are then produced and aerially dispersed to spread the disease over short and long distances. Control: Host plant resistance is the primary control method, but the rust pathogen has the capability to adapt and overcome varietal resistance. Once a variety becomes susceptible, rust can be controlled with the application of fungicide. Clipping or mowing to remove green leaf tissue of susceptible varieties containing rust early in the season may delay the onset of the spring epidemic by a few weeks. Detailed information on varietal resistance ratings, fungicide labels and use recommendations and clipping can be found on the LSU Ag Center website: www.lsuagcenter.com. Look in “Best Management Practices for Minimizing the Impact of Brown Rust in Sugarcane.”

Smut (Ustilago scitaminea)

Symptoms: Smut is characterized by the production of a black, whiplike structure at the apex of stalks with smaller than normal diameter. The whip often elongates to a length of 2‐3 feet and curls downward. The whip is covered by a layer of dark brown fungal spores. Prior to the emergence of whips, smut‐infected plants can have a grassy appearance, with many small‐diameter shoots. Source of Inoculum: Tremendous numbers of smut spores are released over timefrom whips and dispersed in air currents to spread the disease over short and long distances. Control: To control smut, grow resistant varieties. Varieties with a high level of resistance to smut include LCP 85‐384, HoCP 85‐845, HoCP 96‐540, HoCP 00‐950, L 01‐283, L 03‐371 and HoCP 04‐838. Varieties with moderate susceptibility include Ho 95‐988, L 97‐128, L 99‐226, L 99‐233 and L 01‐299. High rates of disease increase do not occur under Louisiana climatic conditions, so it is possible to grow varieties with moderate smut susceptibility if a rigorous healthy seed cane program is followed. Tissue culture produced seed cane will have little or no smut infection. Roguing smut‐infected plants with glyphosate is only feasible in seed cane sources with low levels of infection. Avoid planting seed cane sources of smut‐susceptible varieties next to smut‐infected cane. Do not plant seed cane with more than 2 percent smut infection.


FieldCropsSugarcane

Disease

White Stripe (Physiological disorder)

Symptoms: Characterized by variable amounts of longitudinal white striping on leaves of some plants, white stripe usually occurs during spring. The white stripes extend the full length of the leaf. Striping is not considered infectious but rather is a growth response to environmental conditions. Control: None. Plants usually recover after fertilizer effects are felt in the presence of adequate rainfall.

Yellow Leaf (Sugarcane yellow leaf virus)

Symptoms: The underside of the midvein on younger leaves at the apex of mature plants turns bright yellow in infected plants. The yellowing can spread into the leaf blade, and midveins can turn pink in severely infected plants. Due to the short growing season in Louisiana, symptoms are not seen most years because of ripener applications and/or frosts. Despite the lack of visible symptoms, infected plants may exhibit reduced growth and juice quality. Inoculum: The sugarcane aphid acquires the virus during feeding on an infected plant. The aphid retains the virus for life and can transmit the disease during feeding on healthy plants within the same field or in other fields. Control: Certified seed cane produced through tissue culture is tested for sugarcane yellow leaf virus. Continous planting of seed cane with little or no virus infection will keep the incidence of yellow leaf lower. Information is lacking on the disease resistance levels of commercial varieties.


FieldCropsWheat

Disease

Leaf Rust (Puccinia triticina)

Symptoms: Leaf rust is widespread and probably is the most destructive disease on wheat in Louisiana. The leaf rust fungus produces small, yellowish‐orange pustules on the leaves. These masses of spores turn dark as wheat matures. Infection usually begins on lower leaves and spreads upward. Infected leaves turn yellow and die. Control: Resistant varieties are the most practical approach, although fungicides may be used (Table 2).

Stem Rust (Puccinia graminis tritici)

Symptoms: Elongated, reddish‐brown pustules occur on the stem, leaf sheaths, leaf blades and glumes. Pustules rupture the epidermis to expose a powdery, reddish‐brown mass of spores. Fragments of epidermis adhere to sides and ends of pustules to give them a ragged appearance. Source of Inoculum: Has alternate host species of Berberis and Mahonia where new races may occur, but spread in this area primarily is from wheat to wheat. Control: Stem rust is a serious problem in localized regions of Louisiana. Resistant varieties are the most practical approach for control of this disease, although fungicides may be used (Table 2).

Leaf and Glume Blotch (Stagonospora sp.)

Symptoms: The disease appears on the chaff and may be seen as small, irregular, grayish or brownish spots or blotches, which enlarge and become chocolate brown. As the spots age, their centers turn grayish‐white and may include tiny, round, raised black spore‐bearing bodies. Ordinarily, only a few glumes in a head become infected, but in severe cases the entire head is attacked and turns dark brown. Spots on the sheaths are dark brown and often include most of each sheath. Spots on leaves are light colored and usually surrounded by a brown border. Control: Varieties differ in tolerance to leaf and glume blotch. Consult variety recommendations. For fungicide recommendations, please refer to Table 2.

Powdery Mildew (Erysiphe graminis tritici)

Symptoms: Powdery mildew usually is found on leaves but may attack all aboveground parts of the plant. It first appears as small irregular or circular light gray spots on the upper leaf surface. Later, the plant is covered with a “floury” appearance. Leaves eventually become misshapened and die. Control: The application of fungicide for the control of powdery mildew has rarely been economical.

Bacterial Streak/Black Chaff (Xanthomonas campestris pv. translucens)

Symptoms: Symptoms on leaves begin as dark green, water‐soaked spots that eventually become necrotic and develop into streaks. On the heads, black chaff appears as stripes on the glumes, but blackening may be total. Control: Use crop rotation, clean tillage and pathogen‐free seed.

Fusarium Head Blight/ Scab (Fusarium spp.)

Symptoms: The symptoms after flowering appear as a bleaching of the glumes, spikelets, areas of the head or even the entire head. Salmon‐red or pink‐red spore masses frequently form on infected heads. Control: Seed treatment fungicides help but do not entirely eliminate the fungus. Well timed, foliar‐applied fungicides can reduce incidence.


FieldCropsWheat

Disease

Stripe Rust (Pucina striiformis)

Symptoms: The first sign of disease is individual yellow pustules, usually at the top of the leaf. Later, pustules develop in rows, giving the characteristic of striped appearence. Leaves, sheaths, stems and glumes may be attacked. Control: Resistant varieties are the most practical approach for control of this disease, although fungicides may be used (Table 2).

Take‐all (Gaeumannomyces graminis)

Symptoms: Affected plants have shortened, bleached heads that stand erect, and the affected plants are distributed irregularly throughout the field. The stem base is blackish‐brown, and the roots show dark discoloration and are extensively rotted. Control: Maintain balanced soil fertility and use seed treatment fungicides (Table 1).

Tan Spot (Pyrenophora triticirepentis)

Symptoms: Tan spot first appears on the lower leaves as small yellowish‐brown spots that develop into oval spots. Lesion centers become tan and usually are surrounded by a yellow border or halo. As the leaf declines, the spots expand and merge into irregular tan to brown lesions. Control: Deep plow crop residues. Fungicides may be used.

Yellow Dwarf (BYDV)

Symptoms: Leaf discoloration in shades of yellow, red or purple, especially from tip to base and from margin to midrib. Stunting and excessive tillering are noted. White sterile heads may develop. Control: No adequate controls.

Diseases of Apples and Fungicides Labeled for Control

Disease Fungicidesa

Bitter Rot (Glomerella cingulata = Colletotrichum gloeosporioides)

Symptoms: Although infection can occur at any stage of fruit development, most infection occurs after midseason as the fruit approaches maturity. The disease is characterized by sunken and (more or less) soft and watery, pinkish to brown rotten spots on the fruit. The rotten tissue has a bitter taste. Source of Inoculum: The fungus survives from season to season in mummified fruit and in dead wood and cankers. Fungal spores are dispersed primarily in splashing water, and disease develops best under warm, moist conditions. Control: Remove mummified fruit and dead wood. Follow the apple spray schedule. Late cover sprays are important.

Captan, Captec (captan) Luna Sensation (fluopyram +

trifloxystrobin) Merivon (fluxapyroxad + pyraclostrobin)

Pristine (boscalid + pyraclostrobin) Thiophanate Methyl (thiophanate‐methyl)

Ziram (ziram)

Cedar Apple Rust (Gymnosporangium juniperi‐virginianae)

Symptoms: Galls or “cedar apples” are produced on eastern red cedar and yellowish‐orange spots are produced on the leaves and fruit of apples and crabapples. Source of Inoculum: The cedar apple rust fungus survives from season to season on the familiar “cedar apples” on eastern red cedar. Wind‐borne spores are produced during periods of rain in the spring. Control: Rust can be avoided by eradicating cedar trees within 2 miles of apples. Follow the apple spray schedule.

Adament (tebuconazole + trifloxystrobin)

Cuprofix (copper sulfate) Flint (trifloxystrobin)

Fontelis (penthiopyrad) Inspire Super (cyprodinil + difenoconazole)

Luna Sensation (fluopyram + trifloxystrobin)

Penncozeb (mancozeb) Procure (triflumizole) Rally (myclobutanil)

Tebuzol (tebuconazole) Ziram (ziram)

Fire Blight (Erwinia amylovora)

Symptoms: Affects blossoms, leaves, twigs and young fruit. Infected blossoms wilt suddenly and turn dark brown, followed by blighting of leaves and terminals. Infected twigs and leaves turn dark brown to black, and leaves cling to the stem, often remaining attached most of the season. Source of Inoculum: The bacteria overwinter at the base of blighted twigs or in cankers on larger limbs. Bacteria are spread by bees and splashing rain. Control: Spray during bloom with copper fungicides or streptomycin according to manufacturer’s directions. Prune out and burn infected twigs. Cut 12‐15 inches below affected tissue. Dip pruning tools in 10 percent chlorine bleach solution between cuts.

Disease Fungicidesa

Phytophthora Crown, Collar and Root Rot (Phytophthora spp.)

Symptoms: Foliar symptoms include thinning of the canopy, poor shoot growth and gradual decline. Removal of the outer bark reveals a reddish‐brown to brown decay of the phloem and cambium with distinct margins between diseased and healthy tissue. Source of Inoculum: These pathogens are soil‐borne organisms. Control: Use a combination of practices, including proper site selection, improving drainage and managing soil water, using resistant rootstocks and preventive applications of selected fungicides.

FruitCropsBlackberries

Diseases of Blackberries and Fungicides Labeled for Control

Disease Fungicidesa Efficacyb

Rosette (Double Blossom) (Cercosporella rubi)

Symptoms: Infected buds give rise to a proliferation of small shoots or witch’s broom. Infected flower buds also give rise to distorted blossoms from which fruit does not develop. Source of Inoculum: The fungus survives in wild blackberries and dewberries. Spores are wind‐dispersed. Control: Eradicate wild blackberries and dewberries in the vicinity. Remove infected blossom clusters before they open. Remove the floricanes immediately after harvest. Follow the fungicide spray schedule.

Abound, Heritage, Quadris (azoxystrobin)

+++++

Gray Mold (Botrytis cinerea)

Symptoms: The disease results in blighted blossoms and fruit rot and the presence of the characteristic gray fuzzy growth of the pathogen. Source of Inoculum: The fungus survives as sclerotia and on a wide range of plant debris. Spores are wind‐dispersed. Control: Follow the fungicide spray schedule.

Cane Blight (Leptosphaeria coniothyrium)

Symptoms: Dark red to purple lesions form on the canes around wounds. Lesions may be on one side of the cane or may girdle it and kill the shoots. Source of Inoculum: The fungus survives in infected tissues and dead canes. Spores are rain‐splashed. Control: Prune out infected canes and remove floricanes immediately after harvest. Avoid wounding the plants.

Cane and Leaf Rust (Kuehneola uredinis)

Symptoms: First seen on floricanes in late spring when large yellow pustules split the bark. Small yellow pustules develop on the lower surface of leaves on the floricanes and may lead to premature defoliation. Source of Inoculum: The fungus overwinters on infected canes. Spores are wind‐dispersed. Control: Prune out old diseased canes after harvest. Follow the fungicide spray schedule.

Orange Rust (Gymnoconia nitens)

Symptoms: Disease is evident on new growth in spring as many weak, spindly shoots are formed rather than one strong shoot. Bright orange pustules form on the undersides of infected leaves, and no blooms are produced on the floricanes. Source of Inoculum: The fungus overwinters within systemically infected canes. Spores are wind‐dispersed. Control: Use only disease‐free planting materials. Remove infected plants as soon as they are observed. Follow the fungicide spray schedule.

Cabrio (pyraclostrobin) Nova, Rally (myclobutanil)

+++++ +++++ +++++

Septoria Leaf Spot (Septoria rubi)

Symptoms: Frogeye lesions with whitish centers and brown to purple margins are produced on leaves. Similar lesions are found on canes and petioles. Source of Inoculum: The fungus overwinters in dead leaves and stems. Spores are wind‐dispersed. Control: Follow the fungicide spray schedule.

Phytophthora Root Rot (Phytophthora spp.)

Symptoms: Infected primocanes may rapidly wilt and die in the spring or they (and the floricanes) may slowly become chlorotic, wilt and die in the summer. Infected roots exhibit a reddish‐brown discoloration of the cortex. Source of Inoculum: The pathogen can be introduced on infected planting material but it also survives in soil. Spreads primarily in water. Control: Use disease‐free transplants, improve drainage and avoid low spots. Rogue out infected plants and treat surrounding plants with fungicide.

Diseases of Blueberries and Fungicides Labeled for Control


Mummy Berry (Monilinia vaccinii‐corymbosi)

Symptoms: This fungus attacks and kills leaves, twigs, flowers and fruit. Infected fruit turn cream to pink as they begin to mature and then shrivel and harden into “mummies.” Source of Inoculum: The fungus survives in the mummified fruit. Spores are wind‐dispersed. Control: Remove or bury mummified fruit. Follow the fungicide spray schedule.

Bacterial Leaf Scorch and Decline (Xylella fastidiosa)

Symptoms: The initial symptom is a scorching (burning) of the margins of the leaves, which may be limited to individual branches. Leaves may drop prematurely, and developing fruit may suddenly shrivel. New growth in the spring may look chlorotic, with reddish‐purple spotting or discoloration of the leaf margins. Plant will grow slowly and become stunted. Infected plants eventually will die. Source of Inoculum: The pathogen survives from year to year in infected bushes and various alternate hosts. This bacterium is vectored by sharpshooter leafhoppers and other xylem‐feeding insects. Control: Use only disease‐free transplants. Remove infected plants as soon as they are detected. Use insecticides to control the vectors.

Diseases of Citrus and Fungicides Labeled for Control

Disease Fungicidesa

Melanose (Diaporthe citri = Phomopsis citri)

Symptoms: Melanose is caused by a fungus that attacks leaves, shoots and fruit, causing numerous, dark brown dots or spots to develop. These spots are sunken at first but later become raised so area has a rough, sandpaper feel. The spots may be irregularly scattered on the surface of the fruit or they can run in streaks (tear stains). Melanose infections occur only on the young, tender growth, and fruit becomes resistant as it ages. The same fungus that causes melanose can infect ripe fruit after harvest and is one of the two most common causes of fruit decays known as stem‐end rot. Control of melanose, therefore, helps to reduce the losses from stem‐end rot. Source of Inoculum: The fungus colonizes and survives in dead twigs. Fungal spores are spread primarily by rain splashing and wind‐driven rain, although wind‐borne spores also may be produced. Control: Prune out and burn dead wood, which eliminates much of the inoculum. Follow the Citrus Spray Schedule.

Pristine (pyraclostrobin + boscalid)

Scab (Elsinöe fawcettii = Sphaceloma fawcettii)

Symptoms: Scab is primarily a disease of satsumas, tangerines, grapefruits and lemons, as well as sour oranges and trifoliate orange rootstocks. It does not affect the sweet orange. Scab affects fruit, leaves and young shoots, causing irregular, raised, corky, scabby, wartlike outgrowths. Severely scabbed leaves and fruit become misshapen and distorted. The rind of scabbed fruit is thick and puffy. Source of Inoculum: The fungus causing scab survives in old pustules on leaves and fruit. Spores are spread primarily by rain splash. Control: Follow the Citrus Spray Schedule.

Sweet Orange Scab (Elsinöe australis)

Symptoms: Scab is primarily a disease of sweet orange, satsuma, tangerine, grapefruit and lemon, as well as sour orange and trifoliate orange rootstocks. Scab affects fruit, leaves and young shoots, causing irregular, slightly raised, corky, scabby, growths. Source of Inoculum: The fungus causing sweet orange scab survives in old pustules on leaves and fruit. Spores are spread primarily by rain splash. Control: Follow the Citrus Spray Schedule.

Abound (azoxystrobin) Quadris Top (azoxystrobin + difenoconazole)


FruitCropsCitrus

Disease Fungicidesa

Greasy Spot (Mycosphaerella citri)

Symptoms: Yellow, mottled lesions on upper leaf surface with a matching, slightly raised, pale orange to yellow‐brown blister on the lower leaf surface. Affected areas later become dark brown to black with a greasy appearance. Black necrotic specks form on fruit. Source of Inoculum: Ascospores produced in previously infected decomposing fallen leaves during warm, wet periods of late spring and early summer. Control: Follow the Citrus Spray Schedule.



Cuprofix (copper sulfate) Enable (fenbuconazole) Gem (trifloxystrobin)



Post‐bloom Fruit Drop (PFD) (Colletotrichum acutatum)

Symptoms: Water‐soaked lesions are first observed on flower petals. These then turn pink and finally orange‐brown and become hard and dry. The petals do not fall, but the young fruit does, leaving a “button” composed of the remaining parts of the flower. Source of Inoculum: The fungus survives on “buttons,” leaves and twigs, and the spores are spread primarily by rain splash. Control: Follow the Citrus Spray Schedule.

Abound, Heritage (azoxystrobin) Gem (trifloxystrobin)

Headline (pyraclostrobin)

Phytophthora Root Rot, Foot Rot and Gummosis(Phytophthora spp.)

Symptoms: The cortex of infected roots is soft and discolored and sloughs off easily. Growth of and fruit production by infected trees is greatly reduced. Cracked lesions that exude sap are found on infected scions, which can be girdled and killed. Source of Inoculum: The pathogen survives in the soil and moves in running or splashing water. Control: Use resistant rootstock, improve drainage and manage irrigation. Follow the Citrus Spray Schedule.

Brown Rot (Phytophthora spp.)

Symptoms: Light brown, leathery‐appearing spots develop on the fruit, particularly those low in the canopy or touching the ground. A whitish growth may develop under humid conditions. Source of Inoculum: The pathogen survives in the soil and is splashed onto low‐hanging fruit. It can them be spread by rain splash or wind‐driven rain. Control: Prune to remove low‐hanging branches and fruit. Follow the Citrus Spray Schedule.

Disease Fungicidesa

Green Mold and Blue Mold (Penicillium spp.)

Symptoms: These fungi enter the fruit through injuries to the rind. Decay appears as softened, water‐soaked areas that are easily punctured by pressure. Later, white mycelium appears on the surface of the fruit, and a mass of powdery olive‐green (green mold) or blue spores (blue mold) is produced. Source of Inoculum: These fungi are common saprophytes in citrus groves. They also survive on contaminated packing equipment. Control: Prevent fruit injury at harvest. Follow the Citrus Spray Schedule.

Fungi‐phite (phosphite) Switch (cyprodinil + fludioxonil)

Sour Rot (Geotrichum citri)

Symptoms: Lesions appear as soft, water‐soaked spots on fruit at points where an injury has occurred and may increase to involve the entire fruit. White fungal growth develops on the surface of the infected fruit. A strong sour odor is present. Source of Inoculum: This fungus is a common saprophyte in citrus groves. It also will survive on contaminated packing equipment. Control: Prevent fruit injury at harvest. Follow the Citrus Spray Schedule.

Sooty Mold (Capnodium spp.)

Symptoms: The fungi that cause sooty mold are not parasites. They do not penetrate plant tissue and only grow superficially on the honeydew excretions of white flies, aphids, mealy bugs and scale insects. Sooty mold causes a certain degree of injury when it is thick, because it prevents sunlight from reaching the leaf, and it makes fruit black and unattractive. Fruit covered with sooty mold is smaller and does not color well. Control: Control honeydew‐producing insects. Wash off with water.

Diseases of Grapes and Fungicides Labeled for Control


Black Rot (Guignardia bidwellii)

Symptoms: The black rot fungus attacks all parts of the grape plant. Leaf infection appears on the upper surface in early June as tiny reddish‐brown spots. The lesions enlarge to 1/4 inch or more in diameter and become brown with black borders. A ring of black fungal bodies develops near the outer edge of the brown area. Lesions on stems and tendrils are longer and darker than those on leaves. Stem lesions are narrow, sunken and often split lengthwise on the vine. Infections begin to appear on the fruit when the berries are about half grown. Initially, a small white spot forms that enlarges rapidly until the entire berry is rotten. Affected berries soon turn black, shrivel and dry up. Minute black fungal fruiting bodies develop on the surface of the dried fruit. On muscadines, lesions on berries are small, black and scabby. The fruit does not rot. Source of Inoculum: The fungus overwinters in mummified fruit on the vine and ground and within lesions on canes. Control: Follow the fungicide spray schedule for grapes.

Downy Mildew (Plasmopara viticola)

Symptoms: This is primarily a disease of bunch grapes. Muscadines are relatively resistant. All green parts of the vine are susceptible. Leaf lesions are yellowish‐ to reddish‐brown and may appear angular if they are delimited by veins. Infected shoot tips tend to curl. Leaves and shoots become covered with white mycelium. Berries appear grayish and are covered with the downy feltlike growth of the pathogen. Source of Inoculum: The pathogen overwinters in infected leaves. Disease development is boosted by wet weather. Control: Follow the fungicide spray schedule for grapes.

Anthracnose (Elsinoe ampelina = Sphaceloma ampelinum)

Symptoms: Fruit infections have light gray centers and reddish‐brown borders, resembling a bird’s eye. Stem lesions are similar in color and sunken, with slightly raised borders. Leaf spots are gray with dark borders. Later, the center of the lesion drops out, giving a ragged effect. Badly infected leaves become distorted and curl down. Source of Inoculum: The fungus overwinters in infected fruit on the ground or in infected shoots. Control: Follow the fungicide spray schedule for grapes.

Rally, Eagle (myclobutanil) Pristine (boscalid + pyraclostrobin)

Pierce’s Disease (Xylella fastidiosa) Symptoms: This is a disease of bunch grapes. Muscadines are resistant. Symptoms may vary, but generally are characterized by a scorching of the leaf margins. Grape clusters wilt and dry; bud leaves are slow to develop and show water stress during dry periods. Source of Inoculum: The bacterium survives in infected vines and other hosts. It is transmitted by a number of leafhoppers. Control: No practical control is available. Limiting the spread of the insect vector and destruction of wild weed hosts have had limited success. Destroy infected plants.

Quince Rust (Gymnosporangium clavipes)

Symptoms: Infected fruit develop pimply projections and ripen unevenly. Infected twigs become thickened and deformed. Source of Inoculum: The fungus overwinters in cankers on eastern red cedar and some junipers. Spores are wind‐dispersed. Control: Protect developing fruit with fungicides.

Flint (trifloxystrobin) Nova, Rally (myclobutanil) Sovran (kresoxim‐methyl) b


Symptoms: Infected blossoms turn black and die. Tender shoots become infected, resulting in a shoot blight that is characterized by dead leaves that remain attached to the shoot, which often develops into a shepherd’s crook. Source of Inoculum: The bacterium survives in old cankers and is dispersed by splashing rain, wind‐driven rain, bees and other insects. Control: Prune out diseased branches. Spray with streptomycin during bloom period.

Diseases of Pears and Fungicides Labeled for Control

Disease Fungicidesa


Symptoms: Affects blossoms, leaves, twigs and young fruit. Infected blossoms wilt suddenly and turn dark brown, followed by blighting of leaves and terminals. Infected twigs and leaves turn dark brown to black, and leaves cling to the stem, often remaining attached most of the season. Source of Inoculum: The bacteria overwinter at the base of blighted twigs or in cankers on larger limbs. Bacteria are spread by bees and splashing rain. Control: Spray during bloom with copper fungicides or streptomycin according to manufacturer’s directions. Prune out and burn infected twigs. Cut 12‐15 inches below affected tissue. Dip pruning tools in 10 percent chlorine bleach solution between cuts. Use resistant varieties such as Orient, Moon Glow and Biscamp.

Fabraea (Early) Leaf Spot (Fabraea sp.)

Symptoms: The disease begins on the lower leaves in early spring. Spots on the leaves, mostly circular in outline, are dark brown to nearly black, with purplish margins. Spotted leaves turn yellow and shed. Source of Inoculum: The fungus survives mainly in infected leaves on the ground. It may also form minute cankers on the bark of twigs and shoots. Control: Rake and burn fallen leaves. Begin sprays in April after leaves have unfolded. Orient has moderate resistance, and Maxine is very resistant. Follow Pear Spray Schedule.



Ziram (ziram)

Late Leaf Spot (Cercospora sp.)

Symptoms: This disease is first evident about August. The spots are angular to indefinite in outline and brown to grayish. Infected leaves turn yellow and shed. Source of Inoculum: Spread by wind‐borne spores. Fungus may overwinter on diseased leaves or other hosts. Control: Use labeled fungicides.

Topsin (thiophanate‐methyl)

Quince Rust (Gymnosporangium clavipes)

Symptoms: Affects fruit of pear, crabapple, apple, hawthorne and quince. Sometimes affects twigs and buds but seldom leaves. Infected fruit is covered with swellings or pustules that erupt to reveal yellowish to orange powdery spore masses. When each pustule erupts, a white fringe develops around each spore mass. Source of Inoculum: This fungus must have eastern red cedar or

dwarf or prostrate junipers as alternate hosts to complete its life cycle. Galls are formed on the alternate host in which the fungus survives and infects pears and other plants mentioned. Control: Remove alternate host plants in vicinity of desired trees, or remove all galls from cedar trees during the winter or follow a regular spray program beginning at blossom and continuing until fruit is formed. A combination of the above measures may be necessary.

Pear Scab (Venturia pirina)

Symptoms: Dark brown to black spots form on infected fruit, which often are misshapen. Brown lesions form on leaves, but these may appear to be velvety and olive green when the fungus is actively sporulating. Source of Inoculum: The fungus overwinters mainly in infected leaves on the ground but it may also survive in infected twigs. Control: Rake and burn fallen leaves. Begin sprays in April after leaves have unfolded. Follow Pear Spray Schedule.

Diseases of Pecans and Fungicides Labeled for Control

Disease Fungicidesa

Scab (Cladosporium sp.)

Symptoms: Early leaf infections produce pinpoint olive‐brown lesions often on veins of undersides of leaves. Spots enlarge and coalesce until large areas of leaves may become almost black. Lesions on nuts are small, black and circular, slightly raised at first but later sunken. The entire surface of nuts of highly susceptible varieties may appear black from extensive infections. Source of Inoculum: Fungus may overwinter in infested shucks, leaf stems or leaves. The fungus is spread by wind‐borne spores and is boosted by high humidity. Control: Knock off old shucks and stems before spring. Prune out low limbs to improve air circulation in orchard. Follow Pecan Spray Schedule.

Downy Spot (Mycosphaerella sp.)

Symptom: Appears in late spring or early summer as downy spots on the undersides of the leaflets. Later, greenish‐white spots about 1/8 inch in diameter are visible on both sides of the leaves. As the season advances, the color of the spots changes to brown. Source of Inoculum: Fungus lives from year to year in infected leaves. Control: Follow Pecan Spray Schedule.

Vein Spot (Gnomonia sp.)

Symptoms: Spots may originate on vein of leaflets or on leaf stem and are dark brown to black in final stages. On lateral veins, lesions are circular or oval and seldom attain a diameter of more than 1/4 inch. On midribs of leaflets and on leaf stems, spots are long and narrow. When the disease is severe, premature defoliation usually occurs. Source of Inoculum: Fungus lives through the winter on fallen leaves. Control: The pre‐pollination spray and first cover sprays are essential for control.

Agri Tin, Super Tin (triphenyltin hydroxide) Enable (fenbuconazole) Orius (tebuconazole)




Brown Spot (Cercospora sp.)

Symptoms: Early leaf spots are circular, reddish‐brown and often develop grayish concentric zones. Spots become irregular later. Nuts are not infected by this fungus. Usually a problem only when trees lack vigor or where rainfall is unusually high. Premature defoliation often occurs when disease is severe. Source of Inoculum: Fungus lives from year to year in infected spots

on the old leaves. Spores are wind‐borne. Control: Fertilize trees to improve vigor. Follow Pecan Spray Schedule.

Powdery Mildew (Microsphaera sp.)

Symptoms: This disease affects both foliage and nuts, forming a white superficial fungal growth early in the growing season. Source of Inoculum: Lives from year to year on infected leaves and shucks. Control: Include sulfur in the June, July and August sprays at the rate of 6 pounds per 100 gallons or follow Pecan Spray Schedule.

Agri Tin, Super Tin (triphenyltin hydroxide) Enable (fenbuconazole)




Leaf Scorch (Xylella fastidiosa) Symptoms: Begins in midsummer, becoming prevalent by late summer. A tan necrosis begins on leaflet tips or margins and advances in an irregular pattern toward the center of the leaflet. Infected leaflets turn tan, curl and drop from tree, which may be completely defoliated in some instances. Scorch can be caused by a bacterium (Xylella fastidiosa), but other forms of scorch may be caused by such factors as environmental stresses or nutritional imbalances. Source of Inoculum: The bacterium is present in a wide variety of plants, many of which may be symptomless. It is vectored by xylem‐feeding insects. Control: Maintaining trees in good nutritional balance may give some control.

Bunch Disease (phytoplasma) Symptoms: Affected trees have a bushy growth of slender, willowy shoots. The bunch growths are most conspicuous in spring because they leaf out about two weeks earlier than healthy branches. Control: Never use bud or scion wood from affected trees for propagation. Pruning out diseased branches may help arrest the disease. Destroy severely affected trees.

Rosette (Zinc deficiency) Symptoms: Nonvisible zinc deficiencies are known to limit yields through reduced flower formation, excessive blossom drop, poor filling and premature defoliation. Visible symptoms include yellowish mottling of leaves, primarily in top branches, with narrow and crinkled leaflets sometimes having perforations between the veins. Severe deficiencies appear as shortened internodes on new growth, some dieback of terminals and a bunching or rosetting effect. No pathogen involved. Control: Leaf zinc levels should be determined by foliar analysis. Several sprays of 2 to 3 pounds of 36 percent zinc sulfate or 2 to 4 quarts of NZN should be applied to correct deficiencies indicated by the analysis. In acidic soils, dry zinc sulfate salts may be applied to the soil at 0.25‐0.50 pounds per inch of trunk diameter. Use the smaller amounts on sandy soils. In alkaline soils, application of zinc salts to the soil is not effective. Adequate leaf zinc levels must be maintained by foliar or soil applications as determined by annual foliar analysis.

Louisiana Recommendations for the Control of Pecan Diseases

The control of diseases and insects is essential for profitable pecan production in Louisiana. Commercial pecan producers must spray at the proper time with recommended fungicides and insecticides. Learning to identify the major insect pests and diseases of pecans is highly desirable and strongly recommended. To obtain adequate disease control and receive maximum benefit from applied fungicides, spray applications must be made as part of a preventive program. In addition to spraying, cultural practices and sanitation can reduce the severity of certain insects and disease problems. These practices should be followed by both commercial growers and homeowners with only a few trees. Sanitation: Certain leaf diseases (such as scab) and insects (such as the hickory shuckworm) overwinter on shucks and leaves. If these are raked and burned, it will help to reduce the severity of these problems to some extent the following year. Prune dead and broken limbs from trees to remove potential habitats for certain insects and diseases. Fertilization: Proper fertilization will increase production and boost pest control. Well maintained pecan trees are less susceptible to attack by certain diseases and insects. Consult the LSU AgCenter’s Louisiana Cooperative Extensive Service for information on leaf and soil sampling techniques, fertilization and cultural practices. Spray Equipment: Good spray coverage is essential for good disease control and, to a lesser extent, for insect control. A large air blast sprayer (speed sprayer) has proven to be satisfactory for treating large acreages of pecan trees for control of insects and diseases. Caution: The potential for developing strains of pathogens resistant to fungicides is very great in pecan production. To avoid this:

1. Alternate fungicides with different modes of action in the spray program. 2. Do not use several consecutive sprays with one fungicide or similar fungicides. 3. Avoid using higher rates of fungicides than those recommended. Proper calibration is essential.

Diseases of Stone Fruits and Fungicides Labeled for Control


Brown Rot Blossom Blight and/or Fruit Rot(Monilinia spp.)

Symptoms: Occurs on all stone fruits. The brown rot fungus causes blossom and twig blight, fruit rot and canker. Affected blossoms turn gray or light brown and are covered with spores if wet weather prevails. The fungus may invade twigs from infected blossoms, causing twig blight or canker. Fruit infection normally occurs as the fruit nears maturity. Small circular light brown spots develop on fruit, often at insect wounds or spots where scab or other diseases occur. These spots enlarge rapidly if the fruit is mature, often rotting the whole fruit. Eventually, the spots become covered with a brownish‐gray spore mass. Source of Inoculum: The fungus overwinters in peach “mummies” on the tree or ground and in twig cankers. Control: Remove affected peaches from the orchard at harvest. Remove and bury any peach “mummies” remaining on the trees before spring. Destroy wild plum thickets, abandoned stone fruit orchards and fence row seedlings as far away as possible from producing trees. Follow the stone fruit fungicide spray program.

Rhizopus Rot (Rhizopus spp.)

Symptoms: Normally an important post‐harvest disease of fruit only. Fruit breaks down quickly into a soft watery rot after harvest and is covered with “whiskers” or raised white fungal growth with little black spores. Source of Inoculum: Spores are present in soil on organic matter and airborne. Control: Avoid wounding the fruit. Practice sanitation within and around the packing shed. Spray with Botran before harvest.

Botran (dichloran) Merivon (fluxapyroxad + pyraclostrobin)

Bacterial Spot (Xanthomonas arbicola pv. pruni)

Symptoms: The disease occurs on leaves, twigs and fruit of almost all stone fruits. Spots on leaves progress from grayish and water‐soaked to deep purple, brown or black and are angular in shape. Spots fall out to give “shot‐hole” appearance. Fruit are roughened, with cracked, sunken spots. Small, thick‐edged depressed spots occur on twigs, and larger spots or cankers occur on branches or the trunk. Source of Inoculum: The bacterium survives from one year to the next in twig cankers and is primarily rain‐splashed. Control: Obtain healthy, vigorous nursery stock free from bacterial spot cankers. Maintain vigorous growing conditions by proper cultivation and fertilization. Resistant varieties: La. Gold (immune), Bicentennial, La. Premiere (highly resistant), La. Feliciana, Sure Crop, Majestic, Ruston Red and Ouachita Gold.

Scab (Cladosporium carpophilum)

Symptoms: The disease occurs on leaves, twigs and fruit of almost all stone fruits. Spots on fruit are small, circular, dark olive‐greenish, usually about 1/16 to 1/8 inch in diameter. Spots may be distinctly separate or merge, giving a velvety blotch appearance to half or more of the fruit (usually on the attachment end). Spots are superficial, but cracking or distortion of fruit may follow early or severe infection. Source of Inoculum: The fungus lives from year to year in infected twigs. Control: Prune to allow increased air circulation. Avoid low‐lying planting sites. Follow the stone fruit fungicide spray schedule.

Rust (Tranzschelia discolor)

Symptoms: The disease occurs on leaves, twigs and fruit of almost all stone fruits. Brown pustules occur on the lower leaf surface, marked by a yellowish spot on the upper surface. It may cause leaves to drop prematurely, lowering tree vigor. Source of Inoculum: The fungus overwinters as mycelium in twigs or as spores on twigs or leaves clinging to the tree. Control: Follow the stone fruit fungicide spray program.

Peach Leaf Curl (Taphrina deformans)

Symptoms: This disease occurs only on peach trees. It has not been a problem in Louisiana, except on first‐year trees. It apparently does not live over the summer here. In spring, when leaves first appear, they are thickened, and as they develop, the blades becomes puffed and folded with the edges curling inward so that the undersurface of the leaf is a series of concave chambers. Affected leaves become reddish or purplish, later becoming reddish‐yellow and shedding. Source of Inoculum: The fungus lives from one year to the next on limbs or on the ground. Control: Not necessary.

Black Knot (Apiosporina (=Dibotryon) morbosum)

Symptoms: This disease occurs on plum and cherry. Large, rough, coal black, hard swellings or knots occur along the branches, frequently several inches long. Source of Inoculum: The fungus survives in infected tissue of knots or swellings. Control: Prune and burn diseased branches during the fall or winter, making the cut at least 4 inches below the visible infection. Destroy badly infected trees. Remove wild plums in the vicinity of desirable trees.


Crown Gall (Agrobacterium tumefaciens) Symptoms: Occurs on many fruits including apple, pear, peach and plum. Affects roots and crown of host plant, causing galling of tissue and reduction in the movement of water and nutrients through the plant. Source of Inoculum: This bacterium lives in the soil. Control: Check planting stock for galls or swelling, and rogue infected plants. Treat before planting with Galltrol.

Root Rot (Armillaria (= Clitocybe) spp.) Symptoms: Trees appear weak with small yellowish leaves over the entire tree or confined to one or two branches. The entire tree or single branches may die by the end of the summer or the next year. White mycelial growth can be found beneath the bark of roots or base of affected trees at or about the time of death. Source of Inoculum: These fungi live in soil and survive for many years in old, diseased roots. Control: Dig up and burn old roots before planting peach trees. Remove dead trees and as many roots as possible. Fumigate before replanting.





Phony Peach (Xylella fastidiosa) Symptoms: Trees are dwarfed, foliage is abnormally green and fruit remain small. Phony trees have short terminals and profuse lateral branching. Growth starts in the spring earlier than on normal trees. Source of Inoculum: This bacterium lives in infected trees of many species and is spread by xylem‐feeding insects and root grafting. Control: Rogue out and burn all infected trees. Also, destroy wild plum and peach seedlings in the area of producing trees.

Anthracnose Crown Rot (Colletotrichum spp.)

Symptoms: Plants wilt suddenly and die during warm weather. Crowns have a reddish discoloration extending into the center. Black lesions occur on leaf petioles or runners. Disease development is inhibited by cool weather. Source of Inoculum: The fungus survives the winter on infected plant parts or is introduced on infected planting material. Fungal spores are spread primarily by rain splashing and wind‐driven rain. Control: Use disease‐free transplants. Dip plants in a fungicide prior to planting. Rogue out infected plants and treat surrounding plants with fungicides.

Gray Mold (Botrytis cinerea)

Symptoms: This fungus attacks flowers, flower parts, fruit and leaves. On the fruit, this disease causes a rot that is at first light brown and soft (not “leaky”). As the berry rots, it becomes covered with a grayish, powdery growth, and in the final stages of rot, it becomes tough and firm in texture. Source of Inoculum: The fungus survives in the decaying tissues of strawberries and many other plants. Fungal spores are wind‐dispersed. Control: Control leaf diseases and remove dead leaves that can furnish a site for the fungus to develop. Remove infected fruit from the field. Spray with fungicides.

Mature spots may be circular, oval or V‐shaped. Source of Inoculum: The fungus lives from year to year primarily on infected plant tissue. Control: Use disease‐free transplants. Spray with fungicides.

See Leaf Spot section

Leaf Blotch (Gnomonia spp.)

Symptoms: First appears as purplish to brownish blotches on young leaves. Later appears as large, light brown spots on older leaves. May affect fruit as well. Source of Inoculum: The fungus lives from year to year primarily on infected plant tissue. Control: Spray with fungicides.


Leaf Scorch (Diplocarpon earlianum)

Symptoms: The disease first appears on upper leaf surfaces as small purplish spots that enlarge rapidly into irregular purplish blotches from 1/16 to 3/16 inch in diameter. The spots may become numerous and coalesce. In severe cases, the edges of the leaflets curl upward and the tissue dies, giving the plant a scorched appearance. Source of Inoculum: The fungus survives from year to year on infected leaves. Control: Use disease‐free transplants. Rotate strawberry fields, if possible. Spray with fungicides.


Root‐Knot Nematodes (Meloidogyne spp.)

Symptoms: Affected plants are stunted, unthrifty, unproductive and often pale green. Galls or knots on the roots are rather small. Numerous secondary roots may develop at the small swellings. Frequently, blackened, rotten roots are associated with root‐knot problems. Source of Inoculum: Root‐knot nematodes live from year to year in the soil and on the roots of strawberry plants and many weeds. Root‐knot nematodes are more severe in light soil types. Control: Fumigate plant bed soil and field soil. See table on Nematode Control in Fruit Crops.

Summer Dwarf or Bud Nematode (Aphelenchoides besseyi)

Symptoms: Affected plants are severely stunted during the summer and early fall. Older leaflets usually are darker green with a greasy appearance. Young leaflets are reduced in size, usually crinkled and somewhat elongated, with shorter petioles. Margins of leaflets may curl upward in the young leaflets and downward in the older leaflets. Source of Inoculum: Bud nematodes live from year to year on infected daughter plants and in the soil.




Control: Fumigate fields where the disease has occurred. Obtain disease‐free plants. There is no satisfactory treatment to eradicate these nematodes from infected plants.

a Trade name (chemical name) b Efficacy ratings are on a 1‐5 scale where 5 (+++++) is the most effective and 1 (+) is the least effective.

a For more information, see the 2007 Southeast Regional Strawberry Integrated Management Guide of the Southern Region Small Fruit Consortium (http://www.smallfruits.org/SmallFruitsRegGuide/index.htm). b Bare‐root strawberry plants may be dipped in a fungicide suspension prior to planting to provide early season control of root and crown rot diseases. Prior to dipping, the plants should be washed free of any adhering soil. The entire plant should then be dipped in the fungicide solution for two to five minutes or 15‐30 minutes, depending upon the fungicide used (check the label). Plants should then be set in the field as soon as possible.

These routine sanitation measures are an essential part of controlling sweet potato diseases. 1. Grow seed away from other sweet potatoes from virus‐tested foundation seed. 2. Select seed free from disease or nematode cracking. 3. Cut, rather than pull, slips. 4. Bed in problem‐free area and avoid repeated bedding in same site. 5. Rotate on a regular basis.

Nematode Control Field Crops

All crops grown in Louisiana are subject to some type of nematode attack. Some nematodes such as root-knot or cyst nematodes may be very damaging, but others such as stunt or spiral nematodes may not. Different crops, or even different varieties, may differ in their responses to various nematodes. Chemical control should be used if a nematode population appears to be at damaging levels and is likely to cause significant yield losses.

Nematode Control Home Gardens

Root-knot and reniform nematodes cause problems on many vegetables. Cultural practices and resistant varieties can reduce the amount of damage in the garden.

Cultural Controls

1. Plant early before nematodes become active in soil.2. Rotate crops in the garden3. Rotate the garden site each year4. Add organic matter in the form of green manures or mulches to the soil to stimulate

natural enemies of nematodes and improve growing conditions within the soil forplants.

5. Use fallow plowing during parts of the summer to reduce nematode levels.6. Keep the garden clean of weeds and grasses, which serve as natural hosts for

nematodes.7. Keep soil fertility levels high, and have the soil pH in the correct range for your soil

type.8. Provide extra water during prolonged dry spells.9. Remove crops immediately after they are through producing, especially the roots.10. Most of the marigolds (except Signet types) are effective trap crops against root-

knot nematodes. Plant the marigolds solid for at least two to three months and thenplant vegetables.

11. Solarization during the summer months with a sealed plastic cover can help reducenematode levels. Use clear plastic and keep covered for several weeks during thehottest part of the summer (July and August).

Resistant Varieties or Crops

Root-knot resistant varieties include:

Tomatoes – Vine types: Big Beef, Champion, Terrific, Better Boy; Bush types: Celebrity, Crista; Others: Brixmore, Roma

Southern Peas – Mississippi Silver, Mississippi Purple and Magnolia

Resistant crops against reniform include broccoli, cauliflower, corn, okra, onions, peanuts, radishes and turnips.

Seed Treatments Vegetables

For vegetable plantings, always use top‐quality seed from reliable, commercial sources. If seed has not been treated, the following treatments should be used. With all seed treatments, follow directions and safety precautions on the manufacturer’s label. Do not use treated seed for food or feed crops.

1 Captan is an additional treatment for damping off and not a substitute for the above suggestions.

2 Growers can treat their seed in hot water. Heat water in large pot to a temperature of 125 degrees F. Place seed in a loose cloth bag (cheesecloth does well). Water should circulate freely, and seed should not completely fill the bag. Put seed in hot water for 30 minutes, and keep water temperature at 125 degrees F. Then cool quickly in running tap water and spread seed out to dry quickly. Caution: Do not exceed 125 degrees F during the treatment period because this will reduce germination.



3 Tobacco mosaic virus is seed transmitted and easily spread from only one or two infected plants. Mix one part acid concentrate (37 percent) in 19 parts water. Soak seed in HCL solution for five to six hours to destroy virus. Stir occasionally. Rinse seed thoroughly in running tap water (30 minutes) or wash in 10‐12 changes of water to remove acid. Dry quickly.

CAUTION: AVOID CONTACT WITH ACID MIXTURE. ADD ACID TO WATER TO KEEP FROM SPLATTERING.

Suggestions for treating procedure: Place the seed in an airtight jar or other container, spread the required amount of dust over the seed, close the lid and shake or rotate until all seeds are thinly coated. Never have the container more than half full for any one operation.

In treating small quantities of seed, such as a paper packet, tear one corner of the packet and place a pinch of the dust in the package with the seed. Shake the seed and dust together for several minutes.

CAUTION: DO NOT USE TREATED SEED FOR FOOD OR FEED CROPS.


SoilFumigantsandDecontaminantsforGreenhousesandPlantBeds

The objective of fumigating greenhouses and plant beds is the eradication of weeds, nematodes, soil insects, damping off fungi and bacteria. This is critical for the successful production of greenhouse crops and healthy transplants for field use. It is important to prevent the introduction of contaminated tools or soil that have not been properly fumigated after the plant beds have been treated.
