Anthracnose
scouted Aug. 25, 2025
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Wilkes County were being scouted, and it was observed that 10% of the field in random patches was being affected by wilting and yellowing between the veins. Last fungicide and insecticide spray at this site was 3 and a half weeks before the report, but the pattern doesn't seem to indicate chemical injury. Disease seems to be spreading from the original patches. Full pods are developing in unaffected parts of the field. A sample was submitted to the PDIC for diagnosis.
- Conclusion
- 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.
