A chemical or substance that is used to kill nematodes, which are small, worm-like organisms that can harm plants and crops.
Farmers often use nematocides to protect their crops from harmful nematodes.
Nematocide → It is formed from "nemato-" (from Greek "nema", meaning thread) and "-cide" (from Latin "caedere", meaning to kill). The word refers to a substance that kills thread-like roundworms, known as nematodes.
Think of 'thread' ('nema') and 'killing' ('-cide') to remember that a nematocide is something that kills thread-like worms.
