Abstract: Compounds of the formula (I) or salts thereof in which R1 is carboxyl or a derivative of a carboxyl group, preferably a radical of the formula —CN, —C(?X)—Y—R or —C(?X)-Het, in which X is O, S or NRa or N—NRaRb, Y is O, S, NRc or NRc—NRdRe, R is H, a (subst.) hydrocarbon radical (HR) or acyl, and Het is an aliphatic nitrogen heterocycle, where each of the radicals Ra, Rb, Rc, Rd and Re is as defined for R or a radical of the formula —OR*, where R* is as defined for R, R2 is H or (subst.) HR or a heterocyclic radical, or, if Z=O or S, also an acyl radical, (R3)n are n radicals R3, as defined in claim 1, Z is a group of the formula O or S(O)x, where x=0, 1 or 2, and n is an integer 0, 1, 2, 3 or 4, 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.

Abstract: The present invention relates to a compound of the formula (I) or salt thereof
in which
R1 is identical or different at each occurrence and is H, halogen, CN, nitro, SF5, (C1-C8)alkyl, (C2-C8)alkenyl, (C2-C8)alkynyl, (C1-C8)alkoxy, [(C1-C8)alkyl]-carbonyl or (C1-C8)alkylsulfonyl, each of the radicals being unsubstituted or substituted,
or is S(O)p—R7, where
p=0, 1 or 2 and
R7 is (C1-C8)alkyl, (C1-C8)haloalkyl or NR8R9, where
R8 and R9 independently of one another are identical or different and are H, (C1-C8)alkyl, (C2-C8)alkenyl, (C7-C10)arylalkyl, (C7-C10)alkylaryl or (C6-C10)aryl, each of the last-mentioned five radicals being unsubstituted or substituted,
or is a group of the formula
where R10 is (C1-C8)alkyl which is unsubstituted or substituted, and
W=O or S,
A is optionally substituted aryl or an optionally substituted heterocyclic radical,
X is O or S,
R2,R3,R4, and R5 are identical or different and are H, hal
