The present invention relates to agents for protecting crop plants against phytotoxic side effects of herbicides, characterised in that they contain a compound of the formula I <IMAGE> in which R1 denotes alkyl, alkoxyalkyl, cyanoalkyl, aryl which can be monosubstituted or polysubstituted by alkyl, halogen, haloalkyl, alkoxy, phenyl, phenoxy or nitro, arylalkyl, aryloxyalkyl where the aryl radical in each case can be monosubstituted or polysubstituted by alkyl, halogen, haloalkyl, alkoxy, aroyl, arylthio or nitro, or pyridyl R2 denotes halogen or alkyl, X denotes oxygen or sulphur Y denotes oxygen or sulphur and R3 denotes alkyl which can be monosubstituted or polysubstituted by halogen or alkoxy, alkenyl, cycloalkyl, aryl which can be monosubstituted or polysubstituted by alkyl, halogen, alkoxy, haloalkyl, haloalkoxy or nitro, arylalkyl or aryloxyalkyl where the aryl moiety can in each case be substituted by halogen or nitro, in combination with a herbicide. Some of the compounds of the formula I are novel. A process for their preparation is additionally described. |
