Compounds of the formula (I) or salts thereof, n nwhichn R 1 is COOH or a derivative thereof, preferably a radical of the formula —CN, —C(═X)—Y—R or —C(X′R′)(X″R″)—Y—R, in which R is H, a (subst.) hydrocarbon radical, a heterocyclic radical or acyl, Y is a direct bond or O, S, NR c or NR c —NR d R e , n is the integer 1, 2, 3, 4, 5 or 6 and R′, R″, X, X′, X″, R a , R b , R c , R d , R e , R 2 , R 3 (R 4 ) m are as defined in claim 1 are suitable as safeners for crop plants or useful plants against phytotoxic actions of agrochemicals, preferably as safeners against the action of pesticides such as herbicides in these plants,n nwhere compounds of the formula (I) or salts thereof in which R 1 is COOH, R 2 , R 3 are each hydrogen, (R 4 ) m is a hydroxyl radical (m=1) in any position or two radicals R 4 (m=2) in any position, where in the latter case one radical is a hydroxyl group and the other radical is hydroxyl or methoxy, and n is the number 1, are used as safeners for crop plants or useful plants against phytotoxic actions of agrochemicals other than glyphosate. |
