Abstract

Novel substituted N-alkyl-N-sulfenyl-carbamic acid-[2-(4-phenoxyphenoxy)- and 2-(4-phenylthiophenoxy)-ethyl] esters of the formula ##STR1## wherein R.sub.1 is C.sub.1 -C.sub.4 -alkyl, R.sub.2 is phenyl, phenyl substituted by 1 or 2 halogen atoms or by 1 or 2 C.sub.1 -C.sub.4 -alkyl groups or is --C(CH.sub.3).sub.2 --C.tbd.N, R.sub.3 is halogen, C.sub.1 -C.sub.4 -alkyl, or C.sub.1 -C.sub.4 -alkyl substituted by up to 3 halogen atoms, A is oxygen or sulfur, and n is zero, 1 or 2; processes for producing this compound; and compositions for use in the control of pests, particularly the control of pests which infest plants and animals. The novel compounds are especially effective as ovicides against insects which damage plants.
