Anthracnose
scouted Aug. 9, 2021
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Moore county, variety AG59XF0, were scouted and observed defoliation, dieback, browning, and yellowing between the veins. The site is marginal and sunny. The leaves on the bottom half of the soybean plants are starting to yellow. The margins of the leaves are turning brown.
- 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.
