Priority Area: IPM Implementation in Specialty Crops - Grapes

Vermont vineyard acreage was estimated at 175 acres in 2013, and new vineyards are being planted rapidly (Vermont Sustainable Jobs Fund, 2013). While vineyard acreage may appear low compared to other specialty crops, the value of the wine grapes in Vermont is significant. With vineyards at full production producing 10 tons of fruit /ha, and at a price of $15 per bottle, the potential value of the present acreage of Vermont-grown grapes when converted to wine is nearly $10 million. Grape growers must manage numerous disease, weed, and insect pests in their vineyards which, if left unmanaged, can destroy an entire season’s crop (Isaacs, 2007). Because grapes are a relatively new crop to Vermont, many growers are inexperienced with IPM concepts, safe and efficient use of crop protection materials, and pest (especially disease) identification. Those needs will be addressed as program priorities. The Vermont Grape IPM Program is committed to increasing IPM implementation in commercial vineyards across the state by delivering an integrated extension program that addresses priorities identified by growers, IPM advisors, and other industry service providers in the North Central region which includes similar cultivars and growing conditions to Vermont (Isaacs, 2007). Program priorities are also tailored to address regional needs through collaboration with members of the Northern Grapes Project and NE-1020 Winegrape Cultivar Evaluation Project. Grape growers indicate that past information provided by the Vermont IPM Program has resulted in: reduced pesticide applications (70%), improved timing of pest management practices (74%), and improved economic impact of pest management (70%) (Berkett, 2012). Surveys of growers who utilize IPM information from Network for Environmental and Weather Applications (NEWA) indicate an average savings of $19,500 in spray costs and reduction in crop loss of $264,000 annually (Carroll, Petzoldt et al. 2007).


Approach  - 

Specific priorities identified for this program include improved grower identification of grape diseases (anthracnose, phomopsis, downy mildew, powdery mildew), selection/operation of spray application equipment for small and beginning vineyards, and general IPM practices. We will also highlight the Plant Diagnostic Clinic as a resource for insect, weed and disease diagnosis and IPM recommendations since many grape growers are not aware of this resource.

1. Extension Outreach Education. IPM information for Grape growers will be distributed via electronic communications platforms and email lists with over 350 subscribers each year based on stakeholder input and will include time-sensitive articles and a blog of vineyard observations during the growing season which will encourage practices that promote IPM in vineyards. At least 12 newsletters, blog posts, and/or factsheets containing time- and crop-sensitive IPM information including arthropod, disease, and weed management as well as horticultural, food safety, risk management, and vineyard economics issues will be published each season. At least one specific, topical factsheet or article will be posted to eXtension annually to further extend the reach of the program to growers within and beyond the state of Vermont. At least one on-farm workshop will be held annually to demonstrate IPM practices. Outreach communications will integrate site- and region-specific weather and pest models provided by the Vermont network of Cornell University’s Network for Environmental and Weather Applications (NEWA) to provide timely information to growers. Growers will be provided with one-on-one consultations when necessary to provide specific information applicable to unique farm operations. Bradshaw will contribute to presentations at regional grower meetings such as the VT Grape and Wine Council Annual Meeting and New England Fruit and Vegetable Meetings.

2. Grape IPM Guideline Assessment. A selected group of advisory stakeholders will participate in a survey of crop-specific IPM practices practiced in their vineyard operation. (http://extension.umass.edu/ipm/guidelines/ipm-guidelines-wine-grape).
