• Under conditions that delay gcnnination of the seeds, such as low temperallRS or lack of soil swface moisture, the effectiveness of EXTRAZINE II against these weeds may be impaired. , The degree of weed control may be reduced if soil moisture and temperature conditions cause deep gennination of these seeds.

: Under conditions of heavy weed pressure and where several Hushes of this weed is likely to occur, the residual activity ofEXTRAZINE II may IlOI provide adequate control. In these cases, a follow·up treatment with 3 post broadleaf herbicide is recommended.

CONSERVATION TILLAGE PREEMERGENCEUSES

FIeld com, sweet com, popcorn, and field com grown for seed

(30 dQys prior to p/tlnJing until emergence)

EXTRAZINE II may be used for Early Preplant or Preemergence weed control for land going into the production of corn under conservation tillage (including oo-till) programs. Complete any planned early spring tillage prior to application. Tillage after application may reduce the effectiveness of the herbicide treatment

In corn planted in no-till stalk ground (corn, sorghum), stubble ground (soybean, small grains), and any minimum-till land, EXTRAZINE II, when used according to label directions, will

kill most existing small weeds.

Use Table 2 for field com, popcorn, or field corn grown for seed with surface residue >30%.

Use Table 3 for sweet com.

ANNUAL GRASS AND BROADLEAF WEEDS UP TO 3"

Use EXTRAZINE 11 alone before weeds exceed 3 inches in height.

• For best burndown results use a minimum of 20 gaVacre of liquid fertilizer as the carrier.

BROADLEAF WEEDS EXCEEDING J" • If broadleaf weeds exceed 3 in. at application, add 2,4-0 LV

Ester and/or Banvel' and non·ionic surfactant at recom­mended rates.

• Additional weeds controlled with 2,4-D and/or "Banvel" are: wild buckwheat, dandelion. dock, giant ragweed, marestail, pcnnycress. prickly lettuce and tansy mustard.

• To control existing alfalfa, add 0.3 to 0.5 pint/acre of "Banvel" to the spray mixtw"e of EXTRAZINE 11 plus 2,4-0. Apply before the alfalfa exceeds 6 in. in ho:ighl

GRASS WEEDS EXCEEDING 3"

• If grass weeds exceed 3 in. at application, add either Gramoxone Extra' or Roundup' to the tank at the recom· mended rates for these products.

Add I to 2 pi of a non-ionic surfactant pcr 100 gal of spray .

With ''Gramoxone Extra," well established weeds over 6 in. tall will not be well controlled.

Do not apply "Gramoxone Extra" in a suspension type liquid fertilizer containing clay.

BURN DOWN UNDER DRY CONDITIONS OR CONTROL OF SOD GRASSES

For bumdown of existing sod grasses such as orchardgrass, bromegrass, rye or timothy, or when conditions arc very dry, add "Gramoxonc Extra" to the lank mix at the recommended rate.

PERENNIAL GRASS WEEDS UNDER DRY CONDITIONS

For improved control of perennial grasses such as johnsongrass or quackgrass, add "Roundup" at the recommended rate or follow with a postemergence application of DuPont's ACCENT® Herbicide.

WEATHER EFFECTS AND MODE OF ACTION

As a preemcrgence herbicide. EXTRAZINE II is active nainly through the roots, Its effect on weeds is dependent on ldequate rainfall to move the herbicide into the root zone. The soil must be thoroughly wet throughout the zone where weed seeds germinate. (The soil should be too wet to cultivate.)

Under conditions that delay weed germination-such as low temperatures and lack of soil surface moisture--<ll' when germination is extended over a long period. the effectiveness of the herbicide may be impaired. ROIary hoeing. shallow cultivation. or a postemergence herbicide treatment may be useful under these cireumstances. Follow these guidelines: • Rotary hoeing or shallow cultivation is recommended if

there has nO! been adequate rainfall or sprinkler irrigation within about 10 days after application of EXTRAZINE II. and if the helbicide was nO! incorporated at the time of treatmenL

• If the crop is cultivated. tillage should be shallow to minimize diluting the herbicide in the soil.

• If the crop stand is lost due to adverse weather conditions. insects • .:tc .• the field can be replanted the same season to com or sorghum. See "Rotation Crop Guidelines" for replanting interval on sorghum.

• To enhance weed control in areas of less than 25" of annual rainfall or where long dry periods are common. these treat­ments may require shallow incorporation with a tool such as a field cultivator operated at 5 to 7 mph. Incorporation should nOl be more than 3" deep to avoid burying the herbicide. Do nO! use a spike-toothed harrow. deep tillage disk or rolling basket device to incorporate EXTRAZINE II.

GENERAL MIXING AND SPRAYING DIRECTIONS The following general mixing instructions arc recommended:

I. Unless otherwise specified. use at least 10 gal of water per acre for soil applications and at least 15 gal of water per acre for foliar applications. Note: Use sufficient carrier to ensure uniform application. Follow the label requirements of all products used in tank mix combinations.

2. A nitrogen solution or complete liquid fertilizer may replace all or part of the water as a carrier for preernergence or preplant application on corn. F(\r best bumdown. usc a minimum of 20 gal per acre of liquid fertilizer as the carrier. Do nO! apply fertilizer mixtures aflcr the crop emerges. since this may cause crop injury.

3. Always check the tank mix compatibility (fMC) of this or any other formulation before mixing with liquid fertilizer carriers or other formulations. A simple but generally reliable TMC evaluation procedure is explained in the Tank Mix Compatibility Evaluation Procedure section of these mixing instructions.

4. Start with thoroughly clean equipment (See labels of the previous compounds used for cleaning instructions.)

5. Fill the tank at least 112 full with carrier. Start and maintain consistent agitation through all mixing and spraying proce· dures. Make sure the agitation system is working properly and creates a rippling or rolling action on the liquid surface.

6, Slowly add the recommended amount of EXTRAZlNE II to the tank or inductor.

7. Fill the tank to 75% capacity with carrier. Filling bypass lines should be kept below the liquid surface. Increase tank agitation. as necessary. to maintain the rippling or rolling action on the liquid surface.

8. If desired. add the appropriate emulsible crop oil, crop oil concentrate. or other tank mix formulations. Slurry these additional ingredients before adding :hem to the tank. if the compatibility test shows it to be necessary.

9. Finish filling the tank. maintain in,: sJ~f.cicnt agit:.tion:'t all . '. times to ensure surface action. I., boJ! ~pray tanks dnd nurse tanks. ensure that the EXTRAZlNF, lI,i~ comp!tt~ly . , dispersed and in uniform suspensi(." before api'lyi,,!;' it.

10. Tank mixtul"~ should always be.app!i~d imrn<~i"ttll after preparation. If. fOf any feason. this js nljl possible. ~gitate the mixture sufficiently to f"mix alll>tlxlt.l:ts. and Shcc~ ,it for c()(nplctc resu\pcnsion before application.

Impregnating Fertilizer with EXTRAZINE /I Alon, I. Add EXTRAZINE II to th' total fertilizer volume

required and mix thoroughly. 2. Add Ag-Sorb or MP-/9 drying agent (or a suitable

amount of another effecti ve drying agent) as needed to insure a spreadable herbicidclfertilizer mixture. n,e need for a drying agent is determined by the wetness of the fertilizer batch. Wetness can change with humidity, nitrogen content. fertilizer type, fertilizer rate, and herbicide rate.

Impregnating Fertilizer with EXTRAZINE /I in Tank Mixes with Other Herbicides

The amount of drying agenl needed will vary depending or. whelher !he producl is a dry or liquid formulalion. EXlRAZINE II and SUTAN+. ERADICANE. DUAL or LASSO can be mixed loge!her in the proper use ratio for simultaneous impregnalion. If !here is a mixing compali­bililY problem then add EXlRAZINE II firsl as follows: I. While fertilizer is blending. add Ihe EXlRAZlNE II 4L.

2. Spray in the EC herbicide and mix Ihoroughly for al leasl 3 minules.

3. Add drying agent 10 insure a spreadable herbicidclfertil­izer mixlure. Generally less Ihan 2% by weighl of drying agent will be needed.

APPLICATION OF IMPREGNATED FERTILIZER Fertilizer Ihal is impregnaled or coaled with EXlRAZINE II musl be applied uniformly. Crop injury andlor poor weed control may resull if impregnaled fertilizer is nol uniformly applied. To ensure uniform applicalion:

Calibrate the fertilizer applicator accuralely. • Do not apply the fertilizer mixture while turning al the

ends of Ihe fields; this may result in excessive application rales causing crop injury. Do nOI double-apply the femlizer across the ends or sides of the field. Apply impregnated fertilizer in or.e pass using air-How or auger-metered application equipment. If other equipment is used. apply 1/2 the recommended rate and overlap each pass by 50%, splitting the middle of each pass to obtain the best distribution pattern.

Apply the fertilizer immediately after impregnation. Impregnated fertilizer may become lumpy and difficult to spread if il is slored.

EQUIPMENT CLEANOUT Equipmenl used 10 impregnale or apply fertilizer impreg­naled wilh EXlRAZINE II alone or combinations wilh olher herbicides must be cleaned oul if the nexl balch of material is to be applied to a crop for which EXTRAZINE II or a combination herbicide is not regislered.

• On land that is not highly ero,dibli. the :­atrazine is 2 Ib a.i. per acre. ,

For po"emergence applicalions. if there nas been no previous soil applicalion to that crop. the maximum rate of atrazine from all sources is 2 Ib aj. per acre. If there has been a previous soil application to that crop. do not exceed a total of2.5 Ib atrazine aj. per acre per calendar year.

CYANAZINE RATE LIMITS One quan of EXTRAZINE II DF contains 0.75 Ib cyanazine aClive ingredient (aj.). Adhere to the use rate recommendations in this or other kbel. In addition. observe the following restric­tions:

• Do nol apply more than 6.5 Ib total cyanazine aj. (all sources) per acre per year 10 any land.

On ;Iighly erodible land, as defined by the sOil Conservation Service. if plant residue cover is less than 30%. do not apply more than 3.0 Ib total cyanazine a.i. (all sources) per acre per year.

Controlling Droplet Size - General Techniques • Volume - Use high flow rale nozzles to apply the highesl

practical spray volume. Nozzles with higher rated flows produce larger droplets.

• Pressure· Use the lower spny pressures recommended for the nozzle. Higher pressure reduces droplet size and does not improve canopy penetration. WHEN HIGHER FLOW RATES ARE NEEDED. USE A HIGHER-CAPACITY NOZZLE INSTEAD OF INCREASING PRESSURE. Nozzle Type· Use a nozzle type that is designed for the intended application. With most nozzle types. nanower spray angles produce larger droplets. Consider using low-drift nozzles.

BOOM HEIGHT Sening the boom at the lowest labeled height (if specified) which provides uniform coverage reduces the exposure of droplets to evaporation and wind. For ground equipment, the boor:l should remain level with the crop. and have minimal bounce.

WIND Drift potential increases at wind speeds of less than 3 mph (due to inversion potential) or more than 10 mph. However. many factors. including droplet size and equipmenl type detennine drift potential al any given wind speed. A VOID GUSTY AND WINDLESS CONDmONS. Note: Locallrrrain can influence wind panerns. Everyappli­cator should be familiar with local wind patterns and how they affecl spny drift.

TEMPERATURE AND HUMIDITY When making applications in hot and dry conditions. set up equipment to produce larger droplets to reduce effects of evaporation.

TEMPERATURE INVERSIONS Drift potcntial is high during a temperature invcrsion.
