Bean Binoculars Incident

Wilting, leaf discoloration, and plant death were observed in strips along rows in V6 (sixth trifoliate) soybeans. Hot and dry conditions likely increased plant stress. Symptoms are consistent with Charcoal Rot caused by Macrophomina phaseolina, a seed- and soil-borne fungus. Other symptoms of Charcoal Rot may include brown spots on cotyledons, red or brown circular lesions on leaves (may turn brown/black), and light brown or grey lesions along stems. 

Fungicide applications are not typically recommended for managing charcoal rot, but refer to your local best management practices for more information. No-till systems and irrigation may help preserve soil moisture in dry years. For more information, see this resource on Charcoal Rot and this resource on disease management from NC State Extension.
