Root-Knot Nematode Damage
scouted July 24, 2024
- Background
- Soybeans were scouted at the R1 growth stage and stunted growth, dieback, yellow leaf discoloration, and root rot were observed in patches across the field.
- Conclusion
- This issue was confirmed by the NC State Plant Disease and Insect Clinic to be injury from root-knot nematodes. Symptomology associated with root-knot nematodes in soybeans include non-uniform stunting, wilting, chlorotic patches, and galling found on the roots. In this environment damaging numbers of root-knot nematodes were recovered from the sample submitted. Selecting a resistant variety is the most cost effective preventative measure.
