A module with multiple transcription factors positively regulates powdery mildew resistance in grapevine. [PDF]
Summary Erysiphe necator, the causal agent of powdery mildew (PM), is a fungal pathogen that can severely reduce crop yields. In this study, stable overexpression and silencing demonstrated that the transcription factor VqWRKY46 was identified as a positive regulator of PM resistance in grapevine.

Sensitivity of Erysiphe necator to Demethylation Inhibitor Fungicides in Virginia [PDF]
Grape powdery mildew (Erysiphe necator) isolates were collected from 2005 to 2007 from vineyards mostly in Virginia but also some in Maryland, North Carolina, and Pennsylvania. Using a leaf disc assay, the isolates were tested against five demethylation inhibitor (DMI) fungicides.

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

Occurrence ofErysiphe necatorChasmothecia and Their Natural Parasitism byAmpelomyces quisqualis [PDF]
In northern Italy, Erysiphe necator overwinters almost exclusively as chasmothecia. From 2004 to 2008, we investigated the occurrence of natural parasitism of grapevine powdery mildew chasmothecia by Ampelomyces quisqualis in the Trentino-Alto Adige region, in northern Italy.
