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 an unsubstituted or substituted 6-membered or 7-membered saturated or monounsaturated or diunsaturated heterocyclic structure having one or two hetero atoms selected from the group consisting of oxygen and sulfer, and their agriculturally useful salts and esters of C.sub.1 -C.sub.10 -carboxylic acids and inorganic acids, are suitable as herbicides.
