Grape Disease note from Mike Ellis: (Ohio State University)

(Taken from 4-7-11 Ohio Grape & Wine Electronic Newsletter)

A new fungicide called Revus Top was registered for use on grapes in 2010. It is a package mix of two fungicides (Revus- Mandipropamid and Difenoconazole). During the 2010 growing season some problems with phytotoxicity (plant damage) was observed on Concord grapes in the
northeast US. We included Revus Top in the 2011 Midwest Small Fruit and Grape Spray Guide and put the following Comment about Revus Top in our 2011 spray recommendations.

“Do not apply Revus Top to “Concord” grapes. In 2010, severe phytotoxicity (leaf burning) was observed on Concord grapes at several locations. Do not apply Revus Top to other American Type grapes (labrusca, labrusca hybrids, and other non vinifera hybrids) where sensitivity is unknown. Phytotoxicity appears to be worse when Revus Top is tank mixed with foliar fertilizers
or adjuvant that increases the rapid uptake of chemicals by leaves. Thus far, vinifera grapes and French-American hybrids (Seyval, Vidal and others do not appear to be sensitive to Revus Top.” Revus Top is a product of Syngenta. In 2011, Syngenta put out a supplemental label on the use of Revus Top on Grapes. The supplemental label is attached to this message. The label states that Revus Top cannot be applied to Concord, Concord Seedless, and Thomcord grapes. And has the following precaution statement:

“Precaution: On V. Labrusca hybrids, and other non-vinifera hybrids where sensitivity is not known-the use of Revus Top by itself or in tank mixes with materials that may increase uptake (adjuvants, foliar fertilizers) may result in leaf burning or other phytotoxic effects”.

As far as I know there should not be a problem on vinifera or French Hybrids. If you want to use it and are not sure about phytotoxicity, you should mix up a small amount and spray a couple of vines as a test for phytotoxicity.

I believe that Revus Top should be an excellent fungicide for grape disease control in the eastern US. It has excellent activity against powdery mildew, downy mildew and black rot and has several other diseases listed on the label. From what I heard last year, it is fairly economical.

Notable Quotables

  1. “The former industrial ports of Calais and Boulogne took on a green hue last week, when spoil heaps used as dumping ground for industrial by-products were turned into vineyards. It is hoped that chardonnay made from the grapes grown on the steep-sloped mounds will be ready for drinking for 2013.”
    From: The Timeline: Wine Production, 4-11-11 – The Independent, UK
  2. “Here's more good news for the wine industry, which is counting on millennials to fuel a new wine boom. A new poll shows vino is the drink of choice for 24% of 21-34 year-olds. The generation still prefers beer (at 37%), but more prefer wine compared with older Generation X drinkers (aged 35-46), who choose beer to wine by 41% to 16%, according to The Harris Poll. Drinkers tend to shift to wine and spirits as they get older, so if the trends hold, millennials are likely to be pleasing the wine industry for years to come.”

Marketing Tidbits

  1. “According to the second annual Millennial Donors Survey, 93% of people ages 20 to 35, who are often characterized as self-centered and disconnected, gave to non-profits.”

Show n Tell

On Friday April 1st, I stayed the night with Paul & Sheila Thomsen at their InnSpiration Bed & Breakfast located just northeast of Linn Grove, IA. This very modern bed & breakfast located in the country is surrounded on two sides by vineyards and a large pond on the rear side. We had an excellent evening of conversation, wine, cheese, crackers and fruit. During the conversation I quickly started to realize that Paul and Sheila had too many irons in the fire. They operate a cash grain farm, operate the bed & breakfast that they built themselves and have another resort rental on the Lake of Woods in Canada. They started planting grapes in 2008 and now have four separate vineyards covering around 6 acres. The primary cultivars growing include Frontenac, St. Croix, Marquette, King of the North, Sabrevois and LeCrescent. They are now working to establish a winery. Oh by the way, Paul is also going to start keeping honeybees this year. It was a very pleasant stay and I would definitely recommend staying there to others.

Paul and Sheila hosted a grape pruning workshop the next day. I was there to lead the workshop. The workshop was sponsored by the Northwest Iowa Grape Growers Association. The workshop went very well. Sheila prepared an excellent lunch for those who had time to stay around after the workshop. Several bottles of both Iowa commercial and hobby wine were consumed during the lunch. We could not of asked for better weather, food, wine and discussion. Pictures below:

The end posts are used telephone posts. The fruiting wire is 3/8” steel cable. Built to last! Butch is the operations manager for the local Rural Electric Cooperative (REC).

Denise and Butch stayed at the InnSpiration Bed & Breakfast the night before and participated in the grape pruning workshop. I stopped by to see their vineyard on my way home after the pruning workshop. 4-2-11





(Left) This picture is from another anonymous vineyard I stopped by last week. Note the galvanized wire running through the mild steel post. This is not a good practice. The galvanized wire will begin to rust and then break where it comes in contact with mild steel post. Rust can be seen at the contact of the two here. 4-1-11










(Left) We want to thank Jana Finnegan and Kurt Schade of Schade Creek Vineyard & Winery for allowing (Below) Dr. Murli Dharmadhikari and staff at the Midwest Grape and Wine Industry Institute to hold their first of four Best Practice Workshops in winemaking at their winery in Waukee, IA.





(Above) Madison County Winery located approx.. 3 miles west of St. Charles, IA held a private open house this past Saturday evening (4-9-11) for family and friends to celebrate their newly constructed tasting room. They plan to have the tasting room open for business Friday, 4-15-11.
