Abstract

Cyclohexenone oxime ethers of the general formula I ##STR1## where R.sup.1 is alkyl, PA1 A is unsubstituted or substituted C.sub.3 -, C.sub.5 - or C.sub.6 -alkylene or C.sub.3 -, C.sub.5 - or C.sub.6 -alkenylene, PA1 X is NO.sub.2, CN, halogen, alkyl, alkoxy, phenoxy, alkylthio, haloalkyl, haloalkoxy, carboxyl, alkoxycarbonyl, unsubstituted or substituted benzyloxycarbonyl and/or unsubstituted or substituted phenyl, PA1 n is 0-3 or 1-5 where X is halogen, PA1 R.sup.2 is alkoxy-alkyl or alkylthio-alkyl, unsubstituted or substituted cycloalkyl or cycloalkenyl, an unsubstituted or substituted 5-membered saturated heterocyclic structure having one or two oxygen and/or sulfur atoms as hetero atoms, an unsubstituted or substituted 6-membered or 7-membered heterocyclic structure having up to two oxygen and/or sulfur atoms and up to two double bonds, an unsubstituted or substituted 5-membered heteroaromatic having up to two nitrogen atoms and one oxygen atom or one sulfur atom, or unsubstituted or substituted phenyl or pyridyl, and their agriculturally useful salts and esters of C.sub.1 -C.sub.10 -carboxylic acids and inorganic acids, processes and intermediates for their preparation, and …
