northern root-knot nematode
species of nematode
Also known as: Meloidogyne hapla
Quick Summary
The northern root-knot nematode (Meloidogyne hapla) is a species of plant-parasitic nematode that causes gall-like swellings, or knots, on plant roots. These nematodes can attack over 2,000 types of plants, including vegetables, cotton, strawberries, and orchard trees, often causing significant losses, particularly in warmer climates. While some species are limited to warmer regions, the northern root-knot nematode can survive in areas where the soil freezes deeply. Infestations are frequently spread through nursery stock.12
