scouted Sept. 22, 2021
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Nash county, variety AG57XF1, were scouted and observed 40% of the field was affected by defoliation, dieback, browning. This is a widespread issue.
- 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.
