Soybean sudden death syndrome
scouted Aug. 23, 2021
- Scientific Name
- Fusarium virguliforme
- Background
- Soybeans in Halifax county were scouted and observed with 25% of the field being affected by defoliation, dieback, yellowing between the veins with a mottled pattern, root rot, and wilting in patches in the field. Symptoms became much worse over the course of a couple of weeks.
- 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.
