Vineyard disease management programs are based on several factors including variety, location, climate, seasonal weather conditions, prior disease history, and grower tolerance for risk. In developing a spray program for fungal diseases on grapes you will require a combination/rotation of fungicides.

Fungicidal sprays for grapes vary in efficacy in controlling the major diseases of grapes. The Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) recognizes two classifications of pesticides: general use and restricted use. While general use pesticides can be purchased and used by anyone, only certified pesticide applicators can purchase and use (or supervise the use of) restricted use pesticides. Double A Vineyards offers only general use pesticides that are not classified as restricted use either federally or in New York State. It is the user’s responsibility to observe all restrictions and requirements pertinent to local, state, and federal guidelines concerning the use of these pesticides, including use of personal protective equipment (PPE), transportation, storage, and record keeping of pesticides.
