Anthracnose
scouted Sept. 9, 2021
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Edgecombe county, variety AG59X9, were scouted and observed browning and yellowing along and between the veins, ring spot/shot hoe/frog eye. There is yellowing and browning of the leaves occurring mainly on the upper most leaves.
- 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.
