The invention concerns the use of certain compounds related to fatty acids to
control nematodes that infest plants or the situs of plants. Nematodes that parasitize
animals can also be controlled using the methods and composition of this invention.
Certain of the useful compounds are fatty acid esters that are predicted inhibitors
of nematode delta-12 fatty acid desaturases and can be, for example, from C16 to
C20 in length.
