ABSTRACT:
Compounds of the formula (I) or salts thereof,whichR1is 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 whichR is H, a (subst.) hydrocarbon radical, a heterocyclic radical or acyl,Y is a direct bond or O, S, NRcor NRc—NRdRe,n is the integer 1, 2, 3, 4, 5 or 6andR′, R″, X, X′, X″, Ra, Rb, Rc, Rd, Re, R2, R3(R4)mare as defined in claim1are 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,where compounds of the formula (I) or salts thereof in which R1is COOH, R2, R3are each hydrogen, (R4)mis a hydroxyl radical (m=1) in any position or two radicals R4(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.
