Fusarium wilt
scouted Aug. 20, 2024
- Scientific Name
- Fusarium sp.
- Background
- Soybeans in Vance County were scouted, and it was observed that 15% of the field was affected by stunted patches and chlorosis. The site is a high area and sunny. Plots of stunted growth across the farm are in close proximity to plots of strong growth. Weak plots have barren areas of limited germination. A sample was submitted to the PDIC for diagnosis.
- Conclusion
- This issue was caused by Fusarium. It often occurs in irregular patches in the field. Symptoms are first observed in hot and dry conditions, and they include interveinal chlorosis in the leaves, premature defoliation ,and wilting and reddish/brown vascular discoloration in the stem. This disease is usually a major limiting factor in soybean production, but it's more severe in northern states. It usually doesn't represent a major threat to soybeans in North Carolina.
