Effects of Sunlight Exposure on Grapevine Powdery Mildew Development

Effects of punctuated heat stress on the grapevine powdery mildew pathogen, Erysiphe necator

Grapevine powdery mildew, caused by the ascomycete Erysiphe necator, is a major threat to grapes worldwide. Despite its global impact on grape production, E. necator is sensitive to adverse environmental conditions, such as excess heat, free water and UV radiation. Using detached leaf co-culture assays, 3-d-old single colonies of E. necator were exposed to 1, 2 or 3 consecutive d of punctuated ...
