Anthracnose
scouted Sept. 28, 2022
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Union county, variety AS54FXO, were scouted and observed 10% of the field was affected by browning and yellowing, leaf spots, and wilting. These symptoms were widespread in the upper leaves for the most part. Stink bugs on the top plant leaves, pods, eggs, and egg bearing structure for a large stink bug hatch out. The site has a large stink bug infestation.
- 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.
