Seed decay and pod blight
scouted Aug. 21, 2025
- Background
- Soybeans in Granville County were being scouted, and it was observed that 5% of the field had plants affected by marginal browning and yellowing leaf spots. AGent originally suspected nematodes as some roots seemed stubby, even though they didn't have any galls. A sample was submitted to the PDIC for diagnosis, and a sample was submitted to NCDA to check for nematodes.
- Conclusion
- Diaporthe sp. The cause was identified as seed decay and pod blight, also previously known as Phomopsis blight. It's not a common occurrence in North Carolin,a but persistent arm wet weather preceding and at crop maturity may increase damages caused by this disease. Evidence in mature plants can be seen on the stems and pods, and it appears as black specks (pycnidia) in the stem and pod.
