scouted Aug. 17, 2022
- Scientific Name
- Neocosmospora vasinfecta
- Background
- Soybeans in Carteret county, variety 03, were scouted and observed 50% of the field was affected by Charcoal rot like symptoms.
- Conclusion
- The issue was confirmed to be Neocosmospora stem rot, caused by the fungus Neocosmospora vasinfecta. Symptoms of Neocosmospora root and stem rot can include interveinal chlorosis on the foliage, the presence of small red fungal structures around the crown, and discoloration of the pith. These signs can resemble other stem diseases, especially red crown rot. As interveinal chlorosis progresses, lower leaves may begin to drop earlier than expected. Both the roots and pith may also show varying degrees of discoloration. https://cropprotectionnetwork.org/publications/scouting-for-soybean-stem-diseases
