scouted Aug. 29, 2025
- Scientific Name
- Cercospora kikuchii
- Background
- Soybeans in Halifax County were being scouted, and it was observed that 50% of the field was affected by dieback and browning in random patches. The site is dry and sunny. A sample was submitted to the PDIC for diagnosis.
- Conclusion
- Cercospora kikuchiii. 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.
