Cyclohexenonoxime ethers and herbicidal composition

Cyclohexenone oxime ethers of the formula I <IMAGE> (I) (R1=C1-C6-alkyl; A=substituted or unsubstituted alkylene or alkenylene; Z=a 5-membered or 6-membered heteroaromatic structure; X=substituted or unsubstituted amino, nitro, cyano, halogen, alkyl, C1-C4-alkoxy, C1-C4-alkylthio, C1-C4-haloalkyl, C1-C4-haloalkoxy, carboxyl, C1-C4-alkoxycarbonyl, substituted or unsubstituted benzyloxycarbonyl and phenyl; n=0 to 3, or 1 to 4 where Z is halogen-substituted pyridyl; and R2=alkoxyalkyl or alkylthioalkyl; substituted or unsubstituted cycloalkyl or cycloalkenyl; a substituted or unsubstituted 5-membered saturated heterocyclic structure which contains one or two hetero atoms; a substituted or unsubstituted 6-membered or 7-membered saturated or mono- or diunsaturated heterocyclic structure containing one or two hereto atoms; a substituted or unsubstituted 5-membered heteroaromatic structure containing one to three hereto atoms; substituted or unsubstituted phenyl or pyridyl) and their agriculturally useful salts and esters of C1-C10-carboxylic acids and inorganic acids. The compounds are suitable as herbicides.
