Abstract
Phenylpyrimidines of the formula I as defined below are suitable as antidotes for protecting cultivated plants from phytotoxic effects caused by herbicides. These antidotes, either together with the herbicides or also by themselves, are applied to the plants or incorporated in the soil in which the plants grow, or they are used to treat the seeds of the plants. Suitable herbicides are those belonging to the class of the haloacetanilides, haloacetamides, thiocarbamates, carbamates, nitroanilides, triazines, phenylureas, haloacetic acids, phenoxy- and pyridyloxyphenoxyalkanecarboxylic acid derivatives, benzoic acid derivatives etc. The phenylpyrimidines have the formula I ##STR1## wherein n is an integer from 1 to 5, PA0 R is hydrogen, halogen, cyano, nitro or hydroxyl, a C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 alkoxy or C.sub.1 -C.sub.6 alkylthio group, which is unsubstituted or mono- or polysubstituted by halogen, C.sub.1 -C.sub.6 alkoxy, C.sub.2 -C.sub.12 alkoxyalkyl, C.sub.1 -C.sub.6 alkylcarbonyl, C.sub.1 -C.sub.6 alkylcarbonyloxy, C.sub.1 -C.sub.6 alkoxycarbonyl, C.sub.2 -C.sub.6 alkenylcarbonyl or C.sub.2 -C.sub.6 alkynylcarbonyl, di(C.sub.1 -C.sub.6)alkylamino, C.sub.1 -C.s…
