Anthracnose
scouted Nov. 6, 2020
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Wayne county, variety Dynagro 5878, were scouted and observed plants aborted with no pods. 90% of plants are very small, the remaining are two times as tall but all plants have very few pods. The previous crop was cotton.
- 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.
