Root Knot Nematode

Nematode Pests of Crops

A group of related microscopic roundworms, in the genus Meloidogyne, that invade plant roots and induce swollen galls, disrupting water and nutrient uptake in an extremely broad range of crops including tomato, cotton, soybean and many vegetables worldwide. Collectively, root knot nematodes are considered among the most economically damaging plant parasitic nematodes globally, with estimated annual crop losses in the tens of billions of dollars.

  • Opening definition paragraph
    Root-knot nematodes are plant-parasitic nematodes from the genus Meloidogyne. They exist in soil in areas with hot climates or short winters. About 2000 species of plants worldwide are susceptible to infection by root-knot nematodes and they cause approximately 5% of global crop loss. Root-knot nematode larvae infect plant roots, causing the development of root-knot galls that drain the plant's photosynthate and nutrients.
