Physoderma brown spot and node rot is a disease that has been increasing in incidence in the Midwest over the past 5-10 years. We observed this disease frequently during scouting trips throughout the state conducted in late July. Recently, we have been receiving more reports of this disease and questions pertaining to it’s impact on the crop and management. I recently wrote an article on this disease and management recommendations on the Illinois Field Crop Disease Blog. Click HERE to access the article.
