Fusarium stem rot
scouted Nov. 21, 2022
- Scientific Name
- Fusarium sp.
- Background
- Soybeans in Halifax county, variety LS5909xfs and DG58XT30, were scouted and it was observed that 90% of the field was affected by dieback and severe yield depression, which is widespread and spotty in DG. This site is dry. The two varieties were planted in a field separated by a path. One side as LS5909XFS (local) and the other was DG58XT30 (Dyna Grow). The Local beans are the very tall plants and the Dyna Grow are the shorter ones. Nearly the entire field of locals had a yield of only a few bushels per acre, the Dynagrows that were closest to the locals began to have yield reductions, but the other end of the Dynagrow field was excellent.
- Conclusion
- This issue was identified as Fusarium stem rot, which is caused by various Fusarium species. These species prefer cooler temperatures and wet soil in the early growing season. Soybean root-knot nematodes and Soybean cyst nematodes enhance the Fusarium infection. To prevent infection plant in well draining soil.
