Plant growth regulatory mixture comprising mepiquat and cyclanilide or other cyclopropylmalonic acid anilides

Abstract

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): (R.sup.1).sub.p C.sub.6 H.sub.5-p --NR.sup.2 --CO--C(C.sub.2 H.sub.4)--CO--R.sup.3 --R.sup.4 in which: R.sup.1 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 R.sup.1 radicals, the latter can be identical to or different from one another; R.sup.2 is a hydrogen atom or a lower alkyl group; the qualifier lower denotes a group containing 1 to 4 carbon atoms; R.sup.3 is an oxygen or sulfur atom; R.sup.4 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.
