Pathology Update 6:30-6:45pm

This event will cover an overview of diseases in corn, soybean, and small grain crops along with considerations to maximize the efficacy of fungicide applications for disease control. Discussion will cover common disease symptoms, growth stages most susceptible to disease, fungicide application methods, as well as in-season scenarios that may affect fungicide decisions. Additionally, we will introduce emerging diseases including tar spot of corn and review highlights from new research in short corn hybrids and cover crop termination timing. The goal of this program is to promote dialogue on pathogens of concern, disease thresholds, favorable environmental conditions for disease, and integrated management strategies to reduce disease pressure.
