Compositions having a growth regulatory effect, characterized in that they comprise a mixture of a product A, which is mepiquat chloride, and of a derivative of cyclopropylmalonanilic acid (compound B) of formula (I): (R1)pC6H5-p-NR2-CO-C(C2H4)-CO-R3-R4 in which: R1 represents a halogen atom or an alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, nitro, cyano or acetyl group, it being possible for these various radicals optionally to be substituted by one or a number of halogen atoms; p is an integer equal to 0, 1, 2 or 3; when there are a number of R1 radicals, the latter can be identical to or different from one another; R2 is a hydrogen atom or a lower alkyl group; the qualifier lower denotes a group containing 1 to 4 carbon atoms; R3 is an oxygen or sulfur atom; R4 is a hydrogen atom, or a cation consisting of an ammonium, alkylammonium, polyalkylammonium, hydroxyalkylammonium or poly(hydroxyalkyl) ammonium group or of an alkali metal or alkaline-earth metal, or an alkyl radical which is optionally substituted, especially by hydroxyl or alkoxy groups.
