Abstract

Cyclohexenone oxime ethers of the formula I ##STR1## where R.sup.1 is alkyl, PA1 X is halogen, PA1 n is from 1 to 5, PA1 R.sup.2 is alkoxyalkyl or alkylthioalkyl, unsubstituted of 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 PA1 an unsubstituted or substituted 6-membered or 7-membered heterocyclic structure having not more than two oxygen and/or sulfur atoms and not more than two double bonds, PA1 an unsubstituted or substituted 5-membered heteroaromatic structure having not more than two nitrogen atoms and/or one oxygen atom or one sulfur atom, PA1 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 their use as herbicides.
