Oxime derivatives of the formula (I) <IMAGE> (I) wherein n is 0, 1 or 2 and m is 0 or 1, and Ar is a phenyl radical <IMAGE> a naphthyl radical substituted by R2 and R3, a 5- to 10-membered heterocyclic radical which contains not more than 3 identical or different heteroatoms N, O and/or S and which is substituted by R2, R3 and R4 and can be substituted by oxo or thiono, or if m is O, Ar is a radical R-CO, wherein R is a radical -OR5, in which R5 is an aliphatic group containing not more than 8 carbon atoms or is an araliphatic group containing not more than 15 carbon atoms or is a cycloaliphatic or aromatic group, each containing not more than 10 carbon atoms, while the possible substituents of the aromatic radicals or of the cycloaliphatic radical are halogen, -CN, -NO2, lower alkyl, lower alkoxy, haloalkyl; or R is a radical -NH-CO-NH-R7 or a radical -N(R6)(R7), wherein R6 is hydrogen or lower alkyl and R7 is hydrogen or an aliphatic group containing not more than 8 carbon atoms or an araliphatic group containing not more than 15 carbon atoms, or a cycloaliphatic YSO2R12 <IMAGE> <IMAGE> wherein R9 is hydrogen, a cycloaliphatic, araliphatic or aromatic group which is unsubstituted or mono- or polysubstituted at the ring by CN, NO2, halogen, lower alkyl, lower alkoxy or haloalkyl, or is lower alkenyl, lower haloalkenyl or lower alkynyl, R10 is an aliphatic group or a cycloaliphatic, araliphatic or aromatic group which is unsubstituted or mono- or polysubstituted at the ring by CN, NO2, halogen, lower alkyl, lower alkoxy or haloalkyl, R11 is hydrogen, lower alkyl or cycloalkyl, R12 is lower alkyl or an aromatic group, while Y is O, S SO, SO2 or <IMAGE> and A is C2-C3alkylene or C2-C3alkenylene which is unsubstituted or substituted by halogen, CN or lower alkyl and which together with a carbon chain which is unsubstituted or substituted by halogen, CN or lower alkyl can form a fused ring, and Hal is halogen. These compounds are used for protecting plant crops from the action of aggressive agricultural chemicals.
