Lesion nematodes
scouted July 14, 2023
- Scientific Name
- Pratylenchus sp.
- Background
- Soybean in Sampson county were scouted and it was observed that 2% of field was affected by stunted growth in patches around the field. There are patches of stunted growth in each field. There did not appear to be standing water in these areas.
- Conclusion
- This issue was identified as Soybean lesion nematode, caused by Pratylenchus sp. 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.
