Nematodes are an economically important pest for flue-cured tobacco production. Root knot nematode is particularly damaging due to the wide host range and number of species of root knot nematode found in North Carolina.
Soybean cyst nematode limits yields in every major soybean production region worldwide. This disease note describes SCN in North Carolina and its management.
This publication, chapter 8 of the North Carolina Soybean Production Guide, discusses disease management in soybean production.
Cotton root-knot nematodes are capable of causing significant losses to cotton production. In addition to direct damage, root-knot nematodes allow for secondary pathogens to impact yields. This publication describes root-knot nematodes and their management in cotton.
This factsheet describes and provides management recommendations for the Southern root-knot nematode,Meloidogyne incognita, a widespread pest of corn in North Carolina.
Lesion nematode damage in white or Irish potato is caused by plant-parasitic roundworms. This publication discusses the signs, symptoms, and management of the disease.
Stubby-root nematodes are soilborne, plant-parasitic roundworms that may cause significant damage in corn. This publication covers the symptoms and disease management of the pathogen.
This soybean diseases factsheet discusses sting nematodes, a minor pest of soybean in North Carolina.
This factsheet describes the biology and management of the sting nematode Belonolaimus longicaudatus, an ectoparasitic nematode that affects corn production in North Carolina
This publication discusses the results of greenhouse trials that screened seven sesame varieties for resistance to North Carolina's most common root-knot nematode species. The results of this research will help determine if sesame may play a role in crop rotations for producers managing these pests.
This publication, chapter 7 of the 2025 Peanut Information handbook, discusses plant-parasitic nematodes in peanuts.
Soils were collected from three farms in Wilson County before and after a sesame crop. These farms have a history of root-knot nematode and the growers were interested to see how sesame might impact nematode populations. Nematode populations dropped between 81% and 97%, depending on the farm. These results indicate that sesame may play an important role as an IPM tool to reduce nematode populations in traditional row crop rotations.
This factsheet provides information about management strategies for plant-parasitic nematodes, which can pierce and feed on the roots of soybean and other crops using a special, straw-like apparatus called a stylet. This feeding action causes root damage, which in turn can lead to crop damage and yield loss.
This publication, chapter 10 of the 2025 Cotton Information handbook, covers nematode management practices for cotton production.
