Nematodes in scalp

Nematodes. Plant parasitic nematodes are small worm-like animals, usually about 1 mm in length, which live in soil and feed on plant roots, though some species attack above-ground parts. Most are of little economic importance, but a few species are serious pests and in some instances the entire crop may be lost.
