Anthracnose
scouted Oct. 1, 2024
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Cumberland county were being scouted and it was observed that 30% of the field is affected by yellowing and reddening between the veins and had leaf spots.
- 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.
