Many nematodes parasitize plants and are important agricultural pests. Chemicals used to control them are called nematicides. The nematode that causes the most damage to agriculture is the parasitic root-knot nematode, followed by the root-lesion nematode. There are two types of nematicides: those that kill nematodes that parasitize plants and those that kill nematodes in the soil, with the majority being the latter. The main nematicides are as follows (brand names in parentheses): (1) Halogenated hydrocarbons: Chloropicrin, methyl bromide, D-D (unregistered), DCPI (Mamamol) - mainly used as a soil fumigant.
