Assessing the Risk of Grape Berry Moth Attack in New York Vineyards
Hoffman, Chris; Dennehy, T.
Research on assessing risk of grape berry moth (GBM) damage is the result of questions raised by New York State grape growers about: (1) the possibility of reducing expenditures on insecticides, (2) the possibility of treating only problem areas within vineyards, and (3) why the grape berry moth (GBM) is such a problem in some areas and not in others. Our objective is not to make decisions for growers but to provide the information and methods necessary for the grower to decide what solution for berrymoth control is best for a particular vineyard and financial situation. That is the purpose of studying risk assessment for the GBM. The following are some observations we have made that show the differences between high-risk and low-risk vineyards and a method is presented that may be used to determine what the actual levels of GBM are in particular vineyards.
