The oxime ethers of the formula I below 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, and herbicides are principally chloroacetanilides and thiocarbamates. The oxime ethers have 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 C1-C4 alkyl, C1-C4 haloalkyl, C2-C8 alkoxyalkyl, C3-C4 alkenyl, C3-C4 alkynyl, or together form a 2- to 6-membered alkylene or alkenylene bridge which may be substituted by 1 to 4 C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 alkoxy, C2-C4 alkenyloxy, C2-C8 alkoxyalkyl or C3-C8 alkenyloxyalkyl groups; each of A and B independently of the other is oxygen or sulfur, or one of A and B is the methine group, X is a fluorinated C1-C3 alkyl radical which may also additionally contain chlorine, and Y is hydrogen, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 alkoxy, C1-C4 haloalkoxy or phenyl. |
