The Fungicide Resistance Assessment, Mitigation and Extension (FRAME) Network, a national research and extension team (see individuals below), is working on fungicide resistance in grape powdery mildew. We are interested in hearing about how you approach powdery mildew management and fungicide selection. If you are a vineyard owner, manager, consultant or someone who provides fungicide recommendations for vineyards in the United States, please consider taking our survey!
