Grape Berry Moth

Grape Berry Moth, Paralobesia viteana (Clemens) is

one of the most severe grape pests in the Eastern U.S.

and Lake States. Indications are that it will become a

more dominant pest here in the Midwest as our grape

acreage increases. Though, not a huge pest here in Iowa

yet, there are a few vineyards starting to see some

significant damage. Most of the damage is occurring in

vineyards located near wooded areas where wild grapes

vines are growing.. The larvae of this insect damages

vineyards by feeding on the grape blossoms and berries.

Infested berries may appear shriveled with fine webbing.

Damage by grape berry moth can increase bunch rots.

While GBM larvae may only damage a few berries in a

cluster, it is impractical for growers to remove damaged

berries and webbing from the clusters. There can be 2

or more generations each year.

The GBM overwinters as a pupa in leaf litter. Adults emerge around bloom time to lay eggs of the

first generation singly on fruit stems. Hatch occurs in about 5 days. Emergence of the overwintering

generation peaks in June and continues into July The larvae feed for about 21 days on the blossoms

and young fruit within a thin web. Larva move to the leaves in July where they make a semi-circular

slit, fold the flap over themselves and pupate. Adult moths emerge from the pupae in 10 to 15 days.

(Above) GBM adult moths on 1”

grid sticky trap. The pheromone

impregnated rubber lure is located in

the center.

2

Moths begin laying eggs for the next generation after 4 to 5 days. Larvae of the second and third

generations enter berries and feed within, passing from one berry to another under protection of

webbing. Conspicuous red or purple spots develop on "stung" berries at the point of entry. Second

generation larvae usually enter where the berries touch each other or where the berry joins the stem.

The first step in control should be to clean up, bury or burn the leaf litter under vines in late fall or

winter. Although larvae first appear when the grapes are in bloom, insecticides should be applied

when the berries are the size of small peas. Typically two applications, 10-days apart, are made to

control the first generation. Control of the second generation is more difficult due to an extended

flight period of the egg laying female moths as well as the difficulty of getting adequate spray

coverage inside the cluster as berry size increases. Sprays for the second generation should be timed

for the veraison stage of development. Pheromone traps are available to monitor for adult moth

activity and enhance timing of insecticides for grape berry moth control.

In addition to insect traps to monitor adult emergence, synthetic mating pheromones can also be used

to disrupt their mating. Isomate-GMB is the trade name for the plastic pheromone twist ties used to

disrupt mating. This mating disruption works best in vineyards greater then 2-5 acres to limit the edge

effect of adjacent areas. There is some evidence that applying an insecticide to the vineyard edges

enhances the effect of the mating pheromones placed within the vineyard.

There is a wide range of insecticides that are effective for GBM control. A listing of these

insecticides can be found on page 22 of the 2010 Midwest Small Fruit and Grape Spray Guide found

4,508 Wines Judged at WineMaker International Amateur Wine Competition

From April 16 to 18, 2010 a record total of 4,508 different wines were judged at the 2010

WineMaker International Amateur Wine Competition held at the Equinox Resort in Vermont.

This is the largest wine competition of its kind in the world and represented the largest and most

hobby winemakers throughout North America in all 50 American states and 8 Canadian provinces as

well as a total of 8 different countries. For 3 days, experienced judging panels worked through 796

flights, examining each using the UC-Davis 20-point wine scale evaluating appearance, aroma, taste,

aftertaste and overall impression. The wines were entered in 50 different categories.

The Upper Midwest was well represented in this completion. The number of awards presented by

each Upper Midwest state is shown below:

IA – 4 IL – 20 KS – 2 MN – 9 MO – 26

Show n Tell (check out my KS & TX vineyard/winery road trip)

Paul Klodd, owner/operator of DRS Manufacturing in Jefferson, IA and maker of the Netter Getter

and Nuke-a-Weed invited me on a 5 day road trip this week down through Kansas and Texas. It was

a great offer. I was able to visit some excellent vineyards and wineries in turn for a little driving and

navigation help. We left early on Saturday, May 29th

to participate in a Kansas Grape Growers &

Winemakers Association vineyard field day held at Mike & Lisa Steinert’s vineyard located just

south of Topeka, KS. Paul Klodd demonstrated his Netter Getter and Nuke-a-Weed and I gave a

canopy management presentation. Approximately 15 people were in attendance at this all day event.

Mike and Lisa have approximately 6 acres of vineyard that was first established in 2006. They just

finished planting 1,700 vines this spring. The primary cultivars included Catawba, Chambourcin,

Chardonel, Marechal Foch, Noiret, Norton-Cynthiana, Traminette, Vidal and Vignoles all on a single

high wire trellis system. Mike is in the process of converting parts of the vineyard to a Vertical Shoot

Positioned (VSP) trellis system.

I want to thank Mike & Lisa for being great hosts. Paul and I stayed overnight in their home. While

there, we tasted many of Mikes wines down in his hobby winery located in his “Man Cave”.

On Sunday (the next morning) we left for St. Jo, Texas to see Arche Winery & Oak Creek Vineyards

to visit with Howard Davies and Amy Sterling. They were interested in purchasing a Netter Getter

and wanted to see if it would fit onto their tractor and go down his narrow 7 foot wide rows. It did

and they purchased one. While Paul was talking business, I was touring the winery and vineyards

with Amy Sterling. They purchased an abandoned vineyard growing only Venus grapes in 1999.

They now have approximately 12 acres of vines consisting of Venus, Mourvedre, Carignane,

Grenache, Cabernet Sauvignon, Chardonnay and Syrah. They opened the winery in 2007. The

wines were excellent, as was the hospitality.

tractor. He has enough power to use the

sprayer to shoot thin early in the season.

After a night with some of Paul’s friends in Dallas, we took off for Flat Creek Winery located in the

Texas Foothills approximately 20 miles northwest of Austin, TX. Paul was invited down by Charlie

Kid, the vineyard manager and winemaker. Charlie is very good at what he does and also has a

vineyard consulting business on the side to help others. He was also mentored by Dr. Richard Smart

(AKA - the flying viticulturist) and is a big advocate of the Smart-Dyson training system. The

owners, Rick and Madelyn Naber are Iowegian’s who after living all over the U.S. and several other

countries decided to settle into the Texas Foothills. During the two days we stayed at this Estate

winery, Charlie, Rick and Madelyn treated Paul and I like royalty. Quite frankly, it was the nicest

place this old Iowa Aggie ever stayed.

On the second day of our stay, Texas Agri-life Extension and Flat Creek Winery sponsored/held an

all day vineyard mechanization/management field day. Paul Klodd was invited down to demonstrate

his Netter-Getter vineyard netting machine. The weather was great, the food was great, the wine was

great, the people were great and so was the information. My guess is that approximately 75+ people

showed up to this event. Pictures follow:

Davies constructed and used prior to

large grape bins into this trailer. The old

Sears air conditioner unit above can lower

the temperature down to 32 °F very quickly

if needed. Howard also uses it to cool and

lower the moisture content of his grapes

while at the same time increasing the Brix

content.
