Anthracnose
scouted Aug. 21, 2023
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Tyrrell county were scouted and it was observed that 15% of field was affected by browning, soybean pods stunted in growth, and turned brown. Green pods, stayed green and beans started rotting inside. The site has sandy soil with lots of ram but the soil remained dry.
- Conclusion
- The cause of disease was identified as Anthracnose, caused by Colletotrichum. While usually a disease that shows in the stems and the petioles, it can also cause leaf curling and reddening of the veins. Warm, wet weather favors infection and disease development. Crop rotation and tillage can reduce inoculum, while foliar fungicides will reduce disease, but it's usually not profitable.
