Soybeans in Perquimans County were scouted and it was observed that 15% of field was affected.
Conclusion
The issue was identified as Cercospora blight of soybean. This disease is caused by the pathogen Cercospora kikuchii and although it's common in soybeans it rarely causes significtant yield losses in North Carolina. Chemical management and cultural practices are both options to control Cercospora leaf blight.
