Cercospora leaf spot
scouted Aug. 10, 2023
- Scientific Name
- Cercospora kikuchii
- Background
- Soybeans in Duplin county, variety Asgrow AG54XFO, were scouted and observed 5% of field affected by browning and leaf spots. The affected site is dry and sunny. There is some spotting on the lower canopy and the soybeans are at flowering stage.
- 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.
