Abstract

The invention provides novel mixtures of quaternary ammonium salts having plant growth-regulating properties. The salts, as well as other active ingredients used to regulate plant growth, are dissolved in solvents having either formula II(a) or II(b), as depicted below: wherein“R” is Hydrogen or a C1-C16 alkyl,“n” is 0, 1, 2 or 3,“A” is a C1-C6 alkene or a C1-C6 oxyalkylene,“m” is 1, 2, 3, 4 or 5, and“B” is a straight-chain or branched C2-C8 alkylene.
