Epithio unsaturated aliphatic acids, nitriles, and alcohols and ether, ester and amide derivatives thereof and epoxy unsaturated aliphatic acids, nitriles and alcohols and ether ester and amide derivatives thereof, which are useful in killing and preventing proliferation of insects by upsetting their hormone balance.
Alkyl ethers of 2,3-dihydrobenzofuran where the alkyl chain may contain branched chains, unsaturated bonds, epoxy bridges, and may be substituted with halo, alkoxy, lower alkenyloxy, or lower alkynyloxy substituents useful in killing and preventing the proliferation of insects and other pests by upsetting their hormone balance.
