Grape Pests & Diseases
The University of California has an extensive Integrated Pest Management (IPM) website with a comprehensive section for grapes, including a year-round IPM program and UC IPM guidelines. UC IPM guidelines are an excellent source of information on managing pests, and include UC's official guidelines for monitoring pests and using pesticides or nonpesticide alternatives for managing insect, mite, nematode, weed, and disease pests.
