Sudden death syndrome
scouted June 17, 2024
- Scientific Name
- Fusarium sp.
- Background
- Soybeans in Martin County variety: Revere 4606 were scouted and 15% of a field was observed to be affected by canker, defoliation, dieback, browning and yellowing, leaf spots, and wilting in patches. The field was planted on April 15 at a seeding rate of 125,000 plants per acre using treated seed. Pre-plant fertilizer included 100 lbs of sulfate and 60 lbs of potash. Micropac was applied at 1.
- 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.
