Cercospora leaf blight
scouted Oct. 10, 2025
- Scientific Name
- Cercospora kikuchii
- Background
- Soybeans in Halifax County were being scouted, and it was observed that 50 % of the field was looking off. Plants had enough water during the early stages but had to go through drought stress during the reproductive stages. A sample was submitted to the PDIC for diagnosis. The field is usually a dry site
- 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.
