Abstract

Cyclohexenone oxime ethers I ##STR1## where R.sup.1 is C.sub.1 -C.sub.6 -alkyl, A is unsubstituted or substituted C.sub.3 -C.sub.6 -alkynylene, Z is unsubstituted or substituted phenyl or a 5-membered or 6-membered heteroaromatic and R.sup.2 is C.sub.1 -C.sub.4 -alkoxy-C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.4 -alkylthio-C.sub.1 -C.sub.6 -alkyl, unsubstituted or substituted C.sub.3 -C.sub.7 -cycloalkyl or C.sub.5 -C.sub.7 -cycloalkenyl, an unsubstituted or substituted 5-membered saturated heterocyclic structure having one or two hetero atoms, an unsubstituted or substituted 6-membered or 7-membered saturated or monounsaturated or diunsaturated heterocyclic structure having one or two hetero atoms, an unsubstituted or substituted 5-membered heteroaromatic having one to three hetero atoms 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, are suitable as herbicides.
