scouted Sept. 15, 2021
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Greene county were scouted and observed 55% of the field was affected by widespread browning and yellowing, leaf spots, root rot, and wilting in random patches. The site is low area.
- 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.
