scouted July 8, 2025
- Background
- Soybeans in Hyde county were scouted by grower and 15% of the field was affected by stunting, light green and yellowing plants as well as mottled leaves with brown lesions. A sample was submitted to the PDIC.
- Conclusion
- The issue causing the mottled leaves with brown lesions was identified as Anthracnose, cause by Colletotrichum. While usually a disease that shows in the stem, 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.
