The invention concerns the use of certain compounds related to fatty acids to control nematodes that infest plants or the situs of plants. Nematodes parasitizing animals can also be controlled using the methods and composition of this invention. The useful compounds are inhibitors of nematode delta-12 fatty acid desaturases and can be, for example, from C16 to C20 in length. A feature of these compounds is that their inhibitory effect on the activity of a nematode delta-12 desaturase, or on the viability or fecundity of a nematode, is smaller in the presence of the product of a delta-12 fatty acid desaturase (e.g., linoleate) than in the presence of the substrate of the enzyme (e.g., oleate).
本发明涉及使用某些与脂肪酸有关的化合物来控制侵染植物或植物原位的线虫。利用本发明的方法和组合物还可以控制寄生在动物身上的线虫。有用的化合物是线虫 delta-12 脂肪酸去饱和酶的抑制剂,长度可以是 C16 到 C20。这些化合物的一个特点是,它们对线虫δ-12 脂肪酸去饱和酶的活性或线虫的活力或繁殖力的抑制作用,在有δ-12 脂肪酸去饱和酶的产物(如亚油酸)存在时比在有该酶的底物(如油酸)存在时要小。
