Statewide Viticulture Extension Program

Wayne Wilcox, Professor of Plant Pathology at the NY State Agricultural Experiment Station, Cornell University, writes an annual comprehensive review of disease management programs for vineyards. At 21 pages, this pdf document is lengthy, but packed with excellent information on:

• Changes in fungicide registration, and relative efficacy/cost of different materials
• Biology and control of major grape pathogens
• ‘Putting it all together’ - an overview of fungicide choices based on vine development

Wayne incorporates the latest research results into this document every year. For example, this year’s version includes results of a study on UV light and powdery mildew development - which provides insight on weather-related differences in powdery mildew severity.

Here it is in PDF format:
