Anthracnose
scouted July 25, 2024
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Beaufort County were scouted and it was observed that 10% of the field was affected by browning and yellowing between the veins, root rot, and wilting in patches around the field.
- Conclusion
- The issue 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.
