Anthracnose
scouted Oct. 22, 2021
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Hyde county, variety DynaGro S62XT09, were scouted and observed 100% of the field was affected widespread by leaf spot, speckling, and stippling. This is in a test plot. Plants don't seem to be senescing like they should. The leaves are turning black and seed quality is poor. There seems to be some orange pustules on the underside of the 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.
