OWRI: Fungicide Resistance

Dr. Jay Pscheidt, Professor; Extension Plant Pathology Specialist; OSU Department of Botany and Plant Pathology

Fungicide resistance became a priority this past summer with several documented powdery mildew management failures in vineyards. Several new fungicides have been registered for grapes and some of these contain two active ingredients, and many of the new ingredients are at high risk of encouraging the development of resistant fungal pathogens. These new combinations represent a challenge for sustained plant disease management. In this seminar, Dr. Pscheidt will discuss ideas on how to best utilize these materials in the upcoming season.
