Fungicide Sensitivity of Erysiphe necator and Plasmopara viticola from Virginia and nearby states
… 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 the DM isolates were QoI (azoxystrobin)-resistant, but none were …

Powdery Mildew (Erysiphe cruciferarum) Affects the Allelopathic and Competitive Abilities of Invasive Garlic Mustard (Alliaria petiolata)
… affected negatively by powdery mildew (Erysiphe cruciferarum). While we could not significantly corroborate those findings we did find evidence that E. cruciferarum does inhibit A. petiolata’s allelopathic and competitive effects which benefits some target neighbor species such as …

Characterizing resistance of Erysiphe necator to fungicides belonging to the quinone outside inhibitors and demethylation inhibitors
Practical resistance of Erysiphe necator to quinone outside inhibitors (QoIs) is now widespread, and resistance to demethylation inhibitors (DMIs) has also developed. The goal of this research was to characterize fungicide resistance by elucidating resistance mechanisms and determining its …

Validation of Loci Conferring Adult Plant Resistance to Powdery Mildew in Wheat Cultivar Massey and Identification of Diagnostic Molecular Markers
… the pathogen Blumeria graminis (DC) Speer (Syn. Erysiphe graminis DC) f. sp. tritici, is a major disease of wheat (Triticum aestivum L.). Race-specific resistance is easily identified in the field due to its qualitative phenotype and it is easy to incorporate because it is inherited as a single …
