Herbicidal agent containing at least one compound of the formula <IMAGE> in which R1 and R2 independently of one another in each case represent the radicals hydroxyl, halogen, cyano, nitro, amino which can optionally be substituted by alkyl having 1 - 4 C atoms, straight-chain or branched alkyl which has 1 - 10 C atoms and which can optionally be monosubstituted or polysubstituted by hydroxyl, halogen or cyano, or are straight-chain or branched alkoxy having 1 - 10 C atoms, cycloalkyl having 5 - 7 C atoms, cycloalkoxy having 5 - 7 C atoms, phenyl, phenoxy, alkylthio or alkylsulphonyl having 1 - 4 C atoms, n and m independently of one another in each case represent the numbers 0, 1, 2 or 3, where n + m represent the numbers 1 to 5, R3 represents the radicals hydroxyl, halogen, -OC(O)ZR4 or -OC(O)NR4R5, where R4 represents a straight-chain or branched saturated or unsaturated alkyl radical which has 1 - 15 C atoms and which can optionally be substituted by a phenyl radical, or represents a phenyl radical or a cycloalkyl radical having 5 - 7 C atoms, R5 represents a straight-chain or branched saturated or unsaturated alkyl radical which has 1 - 15 C atoms and which can optionally be substituted by a phenyl radical, or represents a phenyl radical or a cycloalkyl radical having 5 - 7 C atoms, Z is a single bond, oxygen or sulphur and X is halogen, or their salts which are tolerated by plants.d |
