Anthracnose
scouted Nov. 11, 2020
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Wayne county, variety Dyna gr0 5286, were scouted and observed 90% of the field was affected by widespread defoliation, dieback, blackening, reddening, mold mycelium, ring spot/shot hole/frogeye, stem rot, stunting, and wilting. The site is wet.
- 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.
