Cercospora leaf blight
scouted Oct. 2, 2025
- Scientific Name
- Cercospora kikuchii
- Background
- Soybeans in Granville County were being scouted, and it was observed that in 35% of the field there were stunted plants and plants with malformed leaves. There was a suspicion of herbicide injury, and 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 significant yield losses in North Carolina. Chemical management and cultural practices are both options to control Cercospora leaf blight.
