The invention relates to oxime ethers of the formula I <IMAGE> (I) wherein n is 1 or 2, each of R1 and R2 is hydrogen or C1-C4 alkyl each of R3 and R4 is hydrogen, halogen, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 alkoxy, C1-C4 haloalkoxy, C1-C4 alkylthio, C1-C4 haloalkylthio, C1-C4 alkylsulfinyl, C1-C4 alkylsulfonyl, C1-C4 haloalkylsulfinyl, C1-C4 haloalkylsulfonyl or nitro; each of R5 and R6 independently of the other is hydrogen, C1-C4 alkyl, C1-C4 haloalkyl, phenyl or phenyl which is substituted by halogen, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 alkoxy, C1-C4 haloalkoxy, C1-C4 alkylthio, C1-C4 alkylsulfinyl, C1-C4 alkylsulfonyl, carboxyl, carbamoyl, C 1-C4 alkylcarbamoyl, nitro or cyano, or R5 and R6 together are also a 2- to 6-membered alkylene or alkenylene chain which may be substituted by C1-C4 alkyl radicals; X is hydrogen, cyano, nitro, chlorine, C1-C4 alkyl, C1-C4 haloalkyl, C3-C6 cycloalkyl, carboxyl, carbamoyl, C1-C4 alkylcarbonyl, C1-C4 alkoxycarbonyl or C1-C4 alkylcarbamoyl. The oxime ethers of the formula I are able to act as antidotes or safeners to protect cultivated plants from the phytotoxic effects of herbicides. Such cultivated plants are preferably sorghum, cereals, maize and rice.
