Phomopsis blight
scouted Aug. 23, 2021
- Scientific Name
- Diaporthe sp.
- Background
- Soybeans in Pasquotank county, variety AG4XF0, were scouted and observed with 3% of the field being affected by defoliation, yellowing between the veins, and leaf spot in patches throughout the field.
- 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 Carolina 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.
