Cercospora leaf blight
scouted Sept. 15, 2025
- Scientific Name
- Cercospora kikuchii
- Background
- Soybeans in Chowan County were being scouted, and it was observed that 10% of the field was affected by small scattered areas of dead plants as well as leaf spots throughout the field. A sample was submitted to the PDIC for diagnosis. The site is sunny and dry.
- 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 significant yield losses in North Carolina. Chemical management and cultural practices are both options to control Cercospora leaf blight.
