Soybeans in Pasquotank County were scouted, and it was observed that 4% of the field was negatively affected. A sample was submitted to the PDIC for diagnosis
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.
