Soybean lesion nematodes
scouted Oct. 3, 2024
- Scientific Name
- Pratylenchus spp.
- Background
- Soybeans in Edgecombe county were being scouted and observed 10% of the field was affected in a random pattern, possibly by a green stem issue.
- Conclusion
- This issue was identified as Soybean lesion nematode, Pratylenchus spp. These nematodes feed by lysing, or breaking open, cells of the roots, forming cavities. This allows them to migrate intracellularly to continue feeding on healthy tissue. Necrotic lesions can be observed on the root as a result of the damage caused by feeding and movement. When populations are low, above-ground symptoms may not be present, but when populations are high, plants appear stunted, suffer from water and nutrient deficiencies, and eventually dieback.
