The Lake Erie Regional Grape Program Extension Team is looking for a new Viticulture Extension Educator (the position that became vacant with Hans Walter-Peterson's move to the Finger Lakes Grape Program). With an application deadline of July 27, 2007 we would like to ask you assistance in getting this announcement out to anyone you might know that would be interested in the position.
Minimum education required for this position is a Masters Degree with a concentration in Viticulture or closely related field; and there is a requirement of two years relevant experience in Cooperative Extension, Agribusiness, Grape Production, Adult Education or closely related field.
We thank you in advance for your assistance with this extremely important search. (THW)
Viticulture Extension Educator – Lake Erie Regional Grape Program
The 30,000-acre Lake Erie Grape Region of New York and Pennsylvania runs along Lake Erie, from the shores of Lake Ontario to the north to the Pennsylvania/Ohio border. It has a long history of Labrusca (Concord and Niagara) production for use in juice, jams and jellies and sweet wines. The region is also home to an emerging wine grape industry with 16 established wineries participating in the Lake Erie Wine Trail.
The Lake Erie Regional Grape Program (LERGP) is a two-state cooperative extension program of both Cornell and Penn State Universities and is also supported by five county Cooperative Extension Associations. The Regional Extension Educator (Viticulture Specialist) is part of a four member team currently housed at the Lake Erie Center for Grape Research and Extension in Fredonia, NY. In 2008 the program will move to a new $4.5 million research and extension facility in Portland, NY. As part of the extension team, the Viticulture Specialist will provide commercial grape growers, processors and wineries with the research-based knowledge and resources necessary to improve production, management and marketing practices that will enhance profitability and sustain growth of the juice and wine industries of the Lake Erie Region in New York and Pennsylvania.
The successful applicant will provide leadership in planning, conducting, and evaluating a comprehensive education program, to include both independent and cooperative applied research and demonstration projects in diverse technical areas including the nutrition, water management, and mechanization. The established Labrusca industry requires programming aimed at improving production while managing costs and the emerging wine and wine grape industry provides the opportunity to work with varietal and clonal selections appropriate for a premium Lake Erie wine industry as well as soils, site selection, training systems, harvest and handling.

Insects and Diseases observed in vineyards this week include:
|
Grape berry moth - injury levels continue to be low in the majority of vineyards examined. But one high risk Concord site that was checked did have an increase in berry injury in the border row next to the woods. At Concord sites the red coloration of injured berries will be easy to see at this point. Berries of other varieties (e.g. Niagara, etc.) will not show the red coloration due to feeding so a more thorough examination of clusters is needed to detect GBM feeding.

|
| Japanese Beetle - population levels have increased in vineyards throughout the belt and feeding injury is evident in both Concord, Niagara, and wine variety blocks examined. Blocks with problems last season, young plantings and wine variety blocks should be monitored to determine if an insecticide application is needed. | ||

Black rot - symptoms were observed on Concord berries for the first time this season in a vineyard block which has received no effective fungicides for this disease. According to Bryan Hed, black rot symptoms beginning to show on clusters now are from the wetting period which occurred on June 19. Yesterday's rainfall may have initiated an infection period in some vineyard blocks in the belt (depending on the amount of rainfall received and period of time that leaves were wet). In blocks where you find infected berries or leaves consider another fungicide application, especially if there were problems with black rot last season. Remember that berries of all varieties are still susceptible to black rot infections. If you are worried about black rot and plan on putting on a spray within the next 2 days then either Nova or Elite would be good choices due to their post infection activity.

Powdery mildew - observed on clusters at 50% of the Concord sites examined. At these sites I suspect that the buildup of mildew is due to spray timings, coverage and choice of fungicides used. No powdery was seen in Niagara blocks scouted.

| Update from North East, PA | Bryan Hed |
| Here is a brief update from the lakeshore in North East PA. |
|
Weather: We gained 523 gdds in June of 2007. Our current gdd accumulation through July 4 (since April 1) is 916, just slightly ahead of our eight year average (we lost some ground on gdd gain over the last week). We may get some rain this evening (Thursday July 5), but after that our next chance for rain appears to be pushed off until early next week. Wind speeds on Friday and Saturday will be mostly in the single digits (mph) during the morning and evening, but swelling into the low to mid teens during the afternoon hours. |
| Phenology: Concord and Niagara at our location by the lake are just over 11 mm in diameter and about 0.83 grams in weight. |
|
Diseases: We are about 2 and a half (on the lake) to 3 weeks (farther inland) post bloom. This means that Concord/Niagara berries are nearly immune to powdery mildew, but wine varieties will still be susceptible. All varieties are still susceptible to black rot. Black rot fruit infections from the wetting period on June 19 should now be observable. Normally they take 10-14 days (from the infection period) to begin showing up at this time of year. I suspect it will be closer to 14 days with the cooler temperatures we have been having (no symptoms are observable yet from an inoculation on unsprayed berries 10 days ago). Every day is an infection period for powdery mildew. |

Sustainable Viticulture Workbook Project
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)! Please let us know if you are interested by emailing Edith (emb35@cornell.edu or grape@netsync.net)! We would love to hear from you.
Update - We have met with growers from Chautauqua, Niagara, Cattaraugus Counties in New York and several growers from PA. for this project which 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.
The workbook questions are painless, self-reflective and the 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 have appointments set up with more growers through the month for both the workbook portion and Action Plan meetings... If you are interested in working with us on this project please send Edith an email or give her a call at 716.672.6830 so she can schedule an appointment with you.
