The Pest Management Guide for Grapes in Washington presents various chemicals and their uses against pest problems in Washington vineyards. While the recommendations are based on eastern Washington conditions, the information may often be applied to similar pest problems found throughout the state. Specific and more detailed information on pests and diseases can be found in the Field Guide for Integrated Pest Management in Pacific Northwest Vineyards (PNW644).
Recommendations are suggested guidelines. They are not intended to represent pest control programs. The use of other materials and varying rates and treatments for control of particular pests depends on individual circumstances.
Caution: Before making any application of chemicals to any vineyard, READ THE COMPLETE LABEL and be certain that it is up to date.
Always consult with your processor, winery representative, or Extension agent if you have any questions on approved pesticides or pesticide uses. The registration status of various chemicals, formulations, and manufacturers’ products changes rapidly. You may lose your crop or market if you misapply or use improper materials that leave illegal residues on your crop.
Pests Not on Product Label: Some suggested uses of pesticides in this publication are for pests not listed on product labels. These are indicated by the symbol ‘*’. Such uses comply with the federal law (FIFRA), which says a use is consistent with label directions provided the crop or site is on the label and directions concerning rates and interval before harvest are followed.
