Advancing Sustainable Grape Downy Mildew Management: Biopesticide Trials and Risk Assessment System
Grape downy mildew, caused by Plasmopara viticola, significantly damages grape crops (Vitis spp.), reducing yields by up to 75% in unprotected vineyards. The Eastern US faces limited fungicide options due to resistance development and potential legal restrictions on EBDC and captan. The first study …

Fungicide Sensitivity of Erysiphe necator and Plasmopara viticola from Virginia and nearby states
… was undertaken to determine the sensitivity of grape downy mildew (DM, Plasmopara viticola) and powdery mildew (PM, Erysiphe necator) to commonly used single-site fungicides in Virginia and nearby states. DM and PM isolates were collected from 2005 to 2007. In grape leaf disc bioassays, 92% of …

Characterization of fungicide resistance in grape powdery and downy mildew using field trials, bioassays, genomic, and transcriptomic approaches: quinoxyfen, phosphite, and mandipropamid
… and oomycete pathogens is a serious problem in grape production. Quinoxyfen is a fungicide widely used against grape powdery mildew (Erysiphe necator). In 2013, E. necator isolates with reduced quinoxyfen sensitivity (designated as quinoxyfen lab resistance or QLR) were detected in Virginia. …
