IWGA Bus Trip to Michigan Viticulture Field Day

The Iowa Wine Growers Association is hosting a bus trip to attend the 22nd Annual MSU Viticulture Field Day held on Wednesday, 7-27-11 at the Southwest Michigan Research & Extension Center near Benton Harbor, MI. This is one of the largest vineyard field day events held in the Midwest. They typically get over 200+ people in attendance . The vineyard demonstrations and large vineyard equipment trade show is well worth seeing. This event always ends with a fun and tasty steak fry with plenty of Michigan wine put on by the Michigan Grape Society.

The trip starts out on Tuesday morning, 7-26 at Summerset Winery in Indianola and heads for Benton Harbor, MI. The tour will be stopping at Lavender Crest Winery in Colona, IL for lunch and Round Barn Winery, Distillery and Brewery in Baroda, MI in the afternoon before arriving at the Days Inn & Suites in Benton Harbor, MI that evening. The entire Wednesday will be spent attending the MSU Viticulture field day. The trip back on Thursday will include a stop to visit with Dan Nitz at Arrowhead Vineyards in Baroda, MI and then lunch at Anderson Winery in Valparaiso, IN. The bus will arrive back at Summerset Winery late Thursday evening, 7-28.

Arial Roots – A sign of wet soils

I have had several people contact me within the last couple weeks about roots hanging down from the cordon on their vines. They typically want to know what they are, should they remove them and if they do any harm. My typical answer is:

“Aerial roots typically show up when the grapes are growing under very wet conditions. Some of the literature indicates that cold damage may also be involved. I have only seen them under wet conditions. These aerial roots normally pop out at the base of green canes, on spurs or from adventitious dormant buds along the trunk. They really do not have any apparent function when hanging in the air and do not hurt the plant. There is no need to remove them. They often will end up just drying up over time.”

Many areas of the Upper Midwest have seen 3-4 years of above average rainfall. This continued wet weather has taken its toll in many vineyards. Marginal vineyard sites with poor drained soils are being abandoned or tile drainage has been installed. Aerial roots forming on the trunk and cordon is one way the grape plant will respond to water saturated soils. The formation of aerial roots should be considered a notice to evaluate and/or improve the drainage profile of your vineyard.

Get Ready for Japanese Beetles

For the last two weeks several newspapers in Iowa have been reporting about the looming Japanese Beetle crisis about to hit our vineyards. The summer news doldrums must be here and our local media seems to be looking for sensational stories. Yes, Japanese Beetles are a problem for a few vineyards in Iowa but they certainly are not a crisis.

(Left) ISU 2010 Japanese Beetle Distribution map












Reports of Japanese Beetles (JBs) (Popillia japonica) showing up on grapes started this week in Iowa. This is their typical time to start being noticed here in Iowa. The adult beetles normally begins to emerge from the soil around mid-June and will normally start to aggregate in large numbers and do most of their feeding from July through September. Grapes are high on the list of the over 300 species of plants JBs like to chew on. They love to eat grape leaves by eating the top leaf layer of tissue between the veins (skeletonizing). American varieties are fairly resistant. French varieties and the hybrids are more susceptible. Young vines are the most susceptible and can be completely defoliated when high numbers are present. Very seldom will JBs feed on the berries. Moderate feeding on the top leaves in the grape canopy can be common and often will not cause any economic damage. Serious leaf feeding from heavy populations after veraison is more likely to cause economic yield losses. A 15% or greater amount of total leaf defoliation is a common economic threshold used my many to determine if control is needed.

(Left) Adult Japanese Beetle








JB pheromone bait traps can be purchased and used to monitor the emergence of JBs and relative populations. It is recommended to put the traps on the vineyard edges and not in the vineyard. Trapping is primarily a method of monitoring and not control. Bacillus popillae (milky spore disease) is a biological control agent that has been used to protect grassy areas from large larval populations, but it is ineffective against adults entering the vineyard. Adults are capable of flying great distances and will come into the vineyard from untreated areas. Insect nets work well when draped over the entire plant, but can be difficult to remove if tendrils grow through the fine netting. Insect netting also provides bird control and a measure of hail

Insecticide applications are the typical method of control in both home and commercial vineyards. Most insecticides will typically provide insect control for 5-7 days. More or less rainfall can slightly reduce or increase the length of an insecticide’s residual control. Because JB’s typically begin to feed at the top of the vine canopy, directing a narrow insecticide application only the top of the canopy can reduce the amount of insecticide needed and save money.

The following insecticides have the highest JB efficacy rating in the 2011 Midwest Commercial Small Fruit and Grape Spray Guide.

Product Rate/Ac. Approx. $/Ac. Restricted Use PHI* REI*
Baythroid XL 1.6-3.2 oz. $4.50 - $9.50 Yes 3 days 12 hrs
Danitol 2.4 EC 10.7 – 21.3 oz. $14 - $28 Yes 21 days 24 hrs
Mustang Max EC 4 oz. $8 Yes 1 day 12 hrs
Renounce WP 2-4 oz. $6 - $12 Yes 3 days 12 hrs*
Sevin XLR Plus 1-2 qt. $13 - $26 No 7 days 2 days*

*Note –PHI = Pre-harvest Interval. REI = Restricted Entry Interval. Sevin XLR REI is for grapes grown east of th Rockies except for cane girdling or cane turning which is 6 days. Sevin XLR has a minimum re-application interval of 7 days. Renounce has a4 oz. maximum application amount per 14 day interval.

Cannon Falls Wine & Art Festival - 1st of its kind in MN

The Minnesota Legislature recently passed legislation to allow the sale of Minnesota Farm Wines by the glass at wine festivals.

This change was requested by the Minnesota Grape Growers Association’s legislative committee to allow sales by the glass and off sale by the bottle at one annual festival by an association with a minimum of 10 wineries as members. Unfortunately in conference committee it was limited to sale by the glass (limit 2 per attendee) and didn't allow any bottle sales.

The Cannon Falls Wine & Art Festival asked MGGA to be the license holder for their festival and they agreed. This will be the first Minnesota wine festival where Minnesota wines will be sold by the glass!

Festival dates are Saturday and Sunday, July 16th (10am to 6pm) and July 17th (10am to 5pm).

Show n Tell

The Effective Vineyard Spraying workshop held on Saturday, June 25th at the ISU Horticulture Research Station located just north of Ames ended up being very successful. The rain that was falling all morning disappeared in the afternoon allowing Dr. Andrew Landers of Cornell University to demonstrate all the tips, techniques and concepts he had reviewed in the morning classroom session. Much of the information presented came directly from his 2010 book “Effective Vineyard Spraying” that everyone had purchased for this workshop. Here are some selected pictures from the workshop:

(Left) Dr. Andrew Landers demonstrates how to check the output of the individual nozzles of an airblast sprayer. Individual hoses are put on each nozzle.








(Left) Dr. Landers demonstrates how common cash register paper tape can be placed vertically in the vine canopy and used to estimate the airblast sprayer coverage by putting a small amount of food coloring in the spray mixture.








(Left) Dr. Landers demonstrated how to use the Patternator he developed at Cornell University to determine and adjust the spray pattern of an airblast sprayer. Special thanks to Tom Moore at Kirkwood Community College for building this patternator and bringing it over to the workshop!








(Above) The patternator catches the spray from the airblast sprayer and transfers the output to individual measuring tubes connected to the base of the patternator.

(Above) Here is the crew who attended the 6-25-11 Effective Vineyard Spraying workshop held at the ISU Horticulture Research Station north of Ames. Participants from five states attended this workshop (IA, MN, MO, NE and SD). Names have been withheld to protect the innocent! :-)

(Left) Several times during the Effective Vineyard Spraying workshop, Henry Prokop of Homestead Prairie Vineyards at Crete, NE and WunderRosa Winery in Roca, NE described his unique vineyard sprayer that was mounted on his skidsteer. I just had to see this thing. Lucky me! I found it on the WunderRosa Winery homepage under vines. He sits in an enclosed air conditioned cab, creates little soil compaction in the vineyard and can adjust the height of his spray pattern by raising or lowering the sprayer.

I call that NEETO KEENO. mlw






(Above) This flag of flowers was planted in 2002 in Lompoc, CA near Vandenberg Air Force base. It was planted with flowers by local seed companies. It was 740 feet long and 390 feet wide.

I checked Google Maps and was not able to find the flag this year. mlw
