Abstract

The present invention relates to oxime ethers of general formula (I) and to their isomers and isomer mixtures which are possible in which (a) X is an N atom and Y is an oxygen atom or NH, or (b) X is CH and Y is an oxygen atom, in which furthermore R.sub.1 is C.sub.1 -C.sub.4 alkyl; R.sub.2 is hydrogen, C.sub.1 -C.sub.4 alkyl cyclopropyl or cyano; R.sub.3 is cyano, substituted or unsubstituted C.sub.1 -C.sub.6 alkoxycarbonyl, substituted or unsubstituted di(C.sub.1 -C.sub.6 alkyl)aminocarbonyl, substituted or unsubstituted C.sub.1 -C.sub.6 alkyl-S(O).sub.n, substituted or unsubstituted aryl-S(O).sub.n, substituted or unsubstituted heteroaryl, substituted or unsubstituted heterocyclyl or substituted or unsubstituted heterocyclylcarbonyl; and R.sub.4 is C.sub.1 -C.sub.6 alkyl; C.sub.1 -C.sub.6 haloalkyl having 1 to 5 halogen atoms; C.sub.1 -C.sub.4 alkoxy-C.sub.1 -C.sub.2 alkyl; C.sub.2 -C.sub.6 alkenyl which is unsubstituted or substituted by 1 to 3 halogen atoms; C.sub.3 -C.sub.6 alkynyl; C.sub.3 -C.sub.6 cycloalkyl-C.sub.1 -C.sub.4 alkyl which is unsubstituted or substituted by 1 to 4 halogen atoms, and n assumes a value of 1 or 2. These compounds can be used in the form of crop p…
