Evaluating Fungicide Recommendations for Vegetable Crops in the United States: Should More Be Done to Limit the Risks of Fungicide Resistance Development?

Fungicides are an important component of Integrated Pest Management (IPM) programs developed for vegetable production. Without fungicides, commercial vegetable production would not be economically feasible in many regions of the U.S. Recommendations for fungicide use in commercial vegetable production are developed and delivered by Extension in state and regional production guides.
