Root knot nematode
scouted Sept. 19, 2024
- Scientific Name
- Meloidogyne sp.
- Background
- Soybeans in Duplin County of variety DynaGro 5.7, 5 5 were scouted, and it was observed that the fields were affected by dieback, yellowing, stunting, root rot, and stem rot. It was observed that some areas have shorter plants than others and have a thin plant stand. The issue appeared earlier in the growing season, and a sample was submitted to the PDIC for diagnosis. The site is a high area, dry and sunny.
- Conclusion
- Root knot nematodes were identified as part of the issue. High population levels of root knot nematodes present symptoms of non-uniform stunting, wilting, and chlorotic patches, as well as an increased likelihood of disease complex with other soilborne pathogens, and a hindrance to water and nutrient uptake.
