IPM
Grape growers benefit from implementing IPM - environmentally and economically sensible ways to protect crops from insects, plant diseases, weeds, and vertebrate pests. We work with grape processors, growers, local extension educators, faculty, crop consultants, and agricultural businesses to find IPM answers, develop new IPM methods, and deliver IPM information.
NYS IPM Program Mission: The New York State Integrated Pest Management Program develops sustainable ways to manage pests and helps people to use methods that minimize environmental, health and economic risks.

Coming up with the best timing of the various types of insecticides has always been a good topic of discussion. Andy Muza and Tim Weigle have put together a Table: Insecticides for use in New York and Pennsylvania Vineyards (based on one developed by Rufus Isaacs at Michigan State University).

A perfect storm of conditions hit the Lake Erie Region to maximize the economic impact of the weather related events this spring. Historically high bulk juice prices, high crop potential and ten frost or freeze events resulted in a substantial decline in the expected value of the crop. Crop insurance, potential disaster payments and modified production practices will lessen the negative impact somewhat.
