Etymology: "Nematicides" is the plural of "nematicide," a compound built from two parts. The first, "nemati-," comes from "nematode," the Greek-derived name for the thread-like roundworms that include many plant parasites. The second, "-cide," comes from Latin "caedere," meaning "to kill," and appears in familiar words such as "pesticide" and "herbicide." Put together, the parts give a plain literal sense: a substance that kills nematodes. The term is a modern technical coinage built from classical roots, following the same pattern as other agricultural chemical names. A close relative, "nematocide," shows the same formation with a slightly different spelling of the Greek-derived element.

Synonyms: nematocide, nematocide agent, worm killer
