Synergistic growth-regulating mixture

The present invention relates to novel mixtures having growth-regulating properties and more specifically relates to a novel growth regulating mixture of quaternary ammonium salts with growth regulating active ingredients in a suitable solvent. The invention further relates to methods for regulating plant growth. 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 C-Calkyl,"n" is 0, 1, 2 or 3,"A" is a C-Calkene or a C-Coxyalkylene,"m" is 1, 2, 3, 4 or 5, and"B" is a straight-chain or branched C-Calkylene.
