Sustainable Viticulture Workbook Project - Update
We have completed 18 workbooks so far with growers in the Lake Erie Region - we have met with growers from Chautauqua, Niagara, Cattaraugus Counties in New York and several growers from PA.! This project is a cooperative effort of growers, processors, the Finger Lakes Regional Grape Program, Long Island Grape Program and the Lake Erie Regional Grape Program.
Going over the questions in the workbook typically takes about 90 minutes. Depending on your operation and the type of grapes you are growing doesn't make any difference either - we are interested in everyone's input, no matter how many acres you have. Once you have completed the first phase of going through the workbook and answering the questions scaled from 1 (best practice) to 4 (should look at this practice to see if it can be improved), a follow-up visit is scheduled with a member of the SWCD from your county (they have the money to help with cost sharing) to discuss how you might be able to move the practices that received a rating of 4 to a rating closer to 1 - this is the Action Plan meeting. In Chautauqua County these follow-up visits will be scheduled with us (Edith Byrne and TimWeigle) and Dave Wilson from CCSWCD. We have our first Action Plan meetings scheduled for this week!
The workbook questions are painless, self-reflective and the time spent is not unenjoyable! Comments made by growers' are very positive - including how going over the questions makes them think about their total operation, or how they might be able to do or think about something differently, etc.
We continue to hear from growers and are still asking for more volunteers to go through the workbook, answering the questions that pertain to them (and let us know what questions do not pertain to their operation). We have appointments set up with more growers through the month... If you are interested in working with us on this project please send Edith an email at emb35@cornell.edu or give her a call at 716.672.6830 so she can schedule an appointment with you.

Topsin Labeled for Pruning Wound Application for Eutypa Control - From Dr. Wayne Wilcox, NYSAES
Topsin is a replacement for the SLN label New York growers had for years which allowed the use of concentrated Benlate on fresh pruning wounds to 'prevent' Eutypa infections. Although Benlate and Topsin are different chemicals, they break down into the same active ingredient in the vine. Topsin has stepped in to fill the small niche once held by Benlate.
It's likely too expensive and labor intensive to treat all pruning wounds routinely, but if a grower is making major cuts (i.e. the number of cuts is relatively limited but the risk and consequence of cankers forming at the large pruning wounds is relatively high), Topsin can be a valuable tool. 'Major cuts' includes practices such as top-working to a new variety, converting to a new training system, and decapitating winter-injured vines to bring up new suckers and start over.
Editors Note: As Wayne mentioned Topsin will likely be too expensive for treatment of all but the most severely infected Labrusca vineyards. However, there are still ways to reduce the amount of Eutypa in a vineyard. Remember that Eutypa dieback is spread by airborne ascospores that infect the pruning wounds only when free moisture is available. If you can hold off on making the large cuts described by Wayne in the paragraph above, until the weather is warmer and drier the risk of infection is greatly reduced and the need and expense of a Topsin application can be avoided.
Eutypa has been identified as a major factor in the number of missing vines in some vineyards in the region, especially those where a yearly vine replacement strategy is not in place. The best time to identify Eutypa symptoms is during 10- to 12-inches of shoot growth when shoots arising near the canker site are shortened with yellowed, cupped leaves. Vines that are in the early stages of this disease can be identified with flagging tape, cropped this season and have the removal process done the following year.
Double cutting is another method of removing vines infected by Eutypa to get around reinfection of large pruning wounds. Large cuts are made during dormant pruning to vines identified the previous growing season just below the canker. The following spring when the chance for reinfection has passed, another cut can be made significantly below the first cut on the trunk to ensure removal of all the infected portions of the trunks. These trunks should then be removed from the vineyard to limit the availability of spores for reinfection.

Can We Expect a Large Concord Crop in 2007?
I think we have the potential for a large US Concord crop in 2007.
Obviously spring weather conditions can change this forecast. Why do
I think we have the potential? First take a look at this graph of US
Concord tonnage.
2005 we saw a huge crop with all major production area and 2006 saw
major decreases in WA and MI. Both of those areas could rebound with
above average crops in 2007. Here is a graph showing production by major
production areas:
I think it is a possibility that whatever size crop we have, the US crop will be larger than last year. Notice in the second graph that our area continues to be the steadiest producer of Concord grapes!
