Mixtures of optically active cyclohexenone oxime ethers, with an R and S configuration in the oxime ether section of formula (I) where R?1 = C1?-C6? alkyl; X = NO2?, CN, halogen, C1?-C4? alkyl, C1?-C4? halogen alkyl; n = 0-3 or 1-5 if all X substituents are halogen; R?2 = C1?-C4?-alkoxy-C1?-C6?-alkyl, C1?-C4?-alkythio-C1?-C6?-alkyl, optionally substituted C3?-C7? cycloalkyl, optionally substituted C5?-C7? cycloalkenyl, optionally substituted 5-membered saturated heterocyclic ring containing 1 or 2 oxygen and/or sulphur atoms, optionally substituted 6 or 7-membered heterocyclic ring with 1 or 2 non-adjacent oxygen and/or sulphur atoms which may be saturated or singly or doubly unsaturated, optionally substituted aromatic 5-membered heterocyclic ring containing one to two N atoms and one O or S atom, phenyl or pyridyl both of which may bear 1-3 substituents: halogen, NO2?, CN, alkyl, alkoxy, alkylthio, halogen alkyl, alkenyloxy, alkinyloxy and/or -NR?aR?b; R?a = H, alkyl, alkenyl or alkinyl and R?b = H, alkyl, alkenyl, alkinyl, acyl or optionally substituted benzoyl; and their agriculturally usable salts, and esters of C1?-C10? carboxylic acids and inorganic acids of compounds (I), with the proviso that the mixtures contain at least 75 mol % isomers with R configuration in the oxime ether part.
