Project Type: Reimbursable Cooperative Agreement
Start Date: Nov 1, 2018
End Date: Aug 31, 2021
Develop molecular tools to identify fungicide-resistant powdery mildew isolates in the field.
1) Assess fungicide sensitivity, stability and geographic distribution of isolates collected from fresh and wine grapes across two seasons. 2) Validate molecular assays for monitoring resistance to Quinone outside inhibitor and sterol 14a-demethylation inhibitor fungicides in Erisyphe necator and develop markers for other groups (e.g. quinoxyfen). 3) Evaluate fungicide sensitivity and transferability of diagnostic assays in powdery mildew species on strawberry and apple.
