Abstract

Cyclohexenone oxime ethers ##STR1## where R.sup.1 is alkyl; PA0 A is substituted or unsubstituted alkylene or alkenylene, where methylene is replaced by an oxygen atom, a sulfur atom, a sulfoxyl group, a sulfonyl group or --NR.sup.a --, PA0 Z is phenyl or a 5- or 6-membered heteroaromatic structure; PA0 X is substituted or unsubstituted amino, nitro, cyano, halogen, alkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -haloalkoxy, carboxyl, C.sub.1 -C.sub.4 -alkoxycarbonyl, substituted or unsubstituted benzyloxycarbony or phenyl; PA0 n is 0 to 3, or 1 to 5 where X is halogen; PA0 R.sup.2 is alkoxyalkyl or alkylthioalkyl, PA1 substituted or unsubstituted cycloalkyl or cycloalkenyl, PA1 a substituted or unsubstituted 5-membered saturated heterocyclic structure with one or two heteroatoms, PA1 a substituted or unsubstituted 6- or 7-membered heterocyclic structure with 1-2 heteroatoms and 0-2 double bonds, PA1 a substituted or unsubstituted 5-membered heteroaromatic radical with 1-3 heteroatoms, or PA1 substituted or unsubstituted phenyl or pyridyl, and their agriculturally useful salts and esters of C.sub.1 -C.sub.10 -carboxylic a…
