Identification and management of nematodes in field crops

A diverse group of slender worms, most nematode (Nematoda) species are parasitic – feeding on plants, bacterial, fungi or other nematodes. Also called roundworms or eelworms, discover which harm crops and which support a healthy soil ecosystem.

Soil nematodes are microscopic – less than 3 mm long and only 15–100 µm wide. Although difficult to distinguish, they can be identified by their mouthparts. They are grouped according to their feeding habits:

1. Bacterial feeders
2. Fungal feeders
3. Omnivores
4. Predators
5. Plant feeders (parasites)

Plant-parasitic nematodes will always be present in agricultural soils, but many are not serious pests. Find about the plant-parasitic nematodes of most concern in UK agriculture.
