Our guest is Meg McGrath, the Mildew Maven of Cornell. She will be joining us this week to talk all about powdery mildew in vine crops! Meg has spent a career learning how pathogens survive between crops, investigating factors that favor disease development, evaluating fungicides and resistant varieties, developing scouting protocols and action thresholds for timing the initiation of fungicide applications after disease detection.
