Anthracnose
scouted Aug. 10, 2021
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Union county, variety Asgrow 59XF0, were scouted and observed with 45% of the field affect by blight, browning, and yellowing throughout the field. The site is dry. Foliar fertilizer trial symptoms were throughout the entire trial.
- 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.
