scouted May 13, 2024

Soybeans were scouted at the V1 growth stage and round holes in the leaves were observed. The damage detected in this field was minimal.
This injury was confirmed by an NC State Extension Specialist as damage from Bean Leaf Beetles. The economic threshold for bean leaf beetle is 30% defoliation from planting through two weeks prior to blooming (R1), and 15% defoliation two weeks prior to blooming until the pods have filled (R7-R8). This level of defoliation was not observed at this environment.
