Soybeans were scouted at the V2-3 and VC growth stages due to a replant situation, and crooked roots and stem lesions were observed in widespread areas across the field. In this environment there is a substantial amount of biomass from previous cover crop. Initial assumption of injury was heavy insect pressure. This environment also experiences dense deer pressure.
This issue was confirmed by the NC State Plant, Disease and Insect clinic to be Charcoal Rot, Macrophomina phaseolina. Charcoal rot is a soil and seed borne fungus that can infect soybeans at any growth stage.
