Fusarium and Rhizoctonia Root Rot
scouted June 21, 2023
- Background
- Soybeans were scouted at the V3 growth stage and interveinal chlorosis and wilting in irregular patches across the field were observed. Sandy soils are prevalent in this environment, and previous crops in this field have been affected.
- Conclusion
- This issue was confirmed by the NC State Plant, Disease and Insect clinic to be injury from both Fusarium and Rhizoctonia Root Rot. Dry soils earlier in the season could have contributed to the severity of symptoms. There are not options to remedy this issue this season but varietal selection and subsequent use of fungicide seed treatments at planting dates earlier than mid-May are warranted in subsequent years.
