Anthracnose
scouted Aug. 31, 2022
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Stanly county were scouted and it was observed that 10% of field was affected by yellowing in patched. The site is a low area and wet. Wheat appeared to have a problem in this location as well. This area pools water.
- 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.
