A Nematode is a microscopic, slender worm-like animal, less than 1/16 inch long, that lives in the soil, water and plant tissues, and attacks plants. Root nematodes live in the soil and feed on plant roots. Foliar nematodes live in stems and leaves.
Nematodes as Pests
While most nematodes are beneficial (see “Beneficial Nematodes' below for more on their role in the garden), a few species of these translucent, unsegmented worms are plant parasites.
Nematodes are shipped in a finely ground moist clay powder that is added to water. This nematode solution is applied using a watering can, hose end sprayer, backpack or pump sprayer or through irrigation or misting systems.
Nematodes are tiny, microscopic organisms that have a needle-like appendage that burrows into the roots of plants.

Nematodes for Gardeners
For gardeners, beneficial nematodes are attractive as biological pesticides because of their effectiveness and environmental safety. They contain no toxins and are harmless to humans and all other warm-blooded animals.

Pour the nematodes into a full watering can and sprinkle the concoction over affected plants. Once ingested by the slugs, the nematodes will release bacteria that will slowly kill them.
Eelworms (nematodes) and the grubs of narcissus flies are serious threats to daffodils. If bulbs feel slightly soft, show concentric rings of brown and paler tissue when cut across, with a woolly substance at the base, then eelworms are present.
Parasitic nematodes are most often soilborne. Their effects can be minimized by rotating crops, increasing organic matter in the soil, and planting nematode-free material.

Nematodes (the unbeneficial kind) are among those plant-attacking insects repelled by thiophene, the chemical found in marigolds. This chemical is released in the soil from the plant's roots.
Tomato ringspot virus is transmitted from weeds to trees by dagger nematodes (Xiphinema spp.). Nematodes acquire virus by feeding on the roots of an infected plant and later transmit virus when feeding on a healthy plant.
Nematodes ingest bacteria. Protozoa and rotifers present in water films feed on bacteria and plant particles. Predaceous mites and pseudoscorpions prey upon nematodes, fly larvae, other mites and collembolans.

individual pot plants. The nematodes arrive in a dust-like carrier and are mixed with
water before being watered directly on to the soil.
Unlike other pines, white pine is not very susceptible to the pine-wilt nematode that slowly kills trees. It is also more resistant to sawflies, tip blights, and other common needle diseases.
Soak the sponge and squeeze the nematodes into water. It's not long before up to 10 million wind up in the solution, which you then spray onto the lawn and plants. Nematodes are typically applied in the spring.
