The invention relates to synergistic agents and methods of regulating plant growth, which contain, as active substance of the formula I, the ethyl ester of 4-cyclopropyl-3,5-cyclohexanedione-1-carboxylic acid, of the formula I <IMAGE> together with a synergistically effective amount of a phenol ether of the formula II <IMAGE> or of a chloroacetanilide of the formula III <IMAGE> or of a dinitroaniline of the formula IV <IMAGE> or of ethyl N-benzoyl-N-(3,4-dichlorophenyl)-DL-alaninate, or of 1,1-dimethylpyridinium chloride, 2-chloro-N,N-trimethylethylammonium chloride, 2-chloroethylphosphonic acid, 1-phenyl-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)-pent-1-en-3-ol, 1-(4-chlorophenyl)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)-butan-2-ol or of 5-(1-methylthiocyclopropan-1-yl)-[-(trans-2-chloroallyloximino)-propio nyl]-cyclohexane-1,3-dione. R1 to R9 in formulae II to IV have the meaning given in the description. The agent is used for regulating, in particular for inhibiting, the growth of cereals and grass and is advantageously used post-emergence. |
