ABSTRACT:
The invention relates to oxime ethers of the formula I ##STR1## wherein n is 1 or 2, each of R.sub.1 and R.sub.2 is hydrogen or C.sub.1 -C.sub.4 alkyl each of R.sub.3 and R.sub.4 is hydrogen, halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkoxy, C.sub.1 -C.sub.4 alkylthio, C.sub.1 -C.sub.4 haloalkylthio, C.sub.1 -C.sub.4 alkylsulfinyl, C.sub.1 -C.sub.4 alkylsulfonyl, C.sub.1 -C.sub.4 haloalkylsulfinyl, C.sub.1 -C.sub.4 haloalkylsulfonyl or nitro; each of R.sub.5 and R.sub.6 independently of the other is hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, phenyl or phenyl which is substituted by halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkoxy, C.sub.1 -C.sub.4 alkylthio, C.sub.1 -C.sub.4 alkylsulfinyl, C.sub.1 -C.sub.4 alkylsulfonyl, carboxyl, carbamoyl, C.sub. 1 -C.sub.4 alkylcarbamoyl, nitro or cyano, or R.sub.5 and R.sub.6 together are also a 2- to 6-membered alkylene or alkenylene chain which may be substituted by C.sub.1 -C.sub.4 alkyl radicals; X is hydrogen, cyano, nitro, chlorine, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, C.sub.3 -C.sub.6 cycloalkyl, carboxyl, carbamoyl, C.sub.1 -C.sub.4 alkylcarbonyl, C.sub.1 -C.sub.4 alkoxycarbonyl or C.sub.1 -C.sub.4 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.
