The present invention generally relates to stable S-(+)-abscisic acid liquid and soluble granule formulations and methods of making and using such formulations.

Stable S-(+)-abscisic acid liquid and soluble granule formulations

Soluble and stable liquid compositions containing a plant growth regulator selected from the group consisting of cytokinin and a gibberellin, an acid solubilizer such as citric acid, tartaric acid or glycolic acid and a solvent; as well as methods for making and using the composition are disclosed. The compositions improve solubility, handling, stability, safety, as well as activity improvements such as improved plant growth, yield, fruit thinning or sizing and quality. The compositions are soluble and stable by adding an ethoxylated alkyl alcohol wherein the growth regulator is 6-benzyladenine (6-BA) or forchlorfenuron (CPPU) and the ethoxylated alcohol surfactant is Calkyl alcohol in propylene glycol. The compositions may also contain a cytokinin such as 6-benzyladenine (6-BA) or forchlorfenuron (CPPU) that is increased in solubility and activity and by synergistically combined with GAor GAAas well as in storage stability by adding an antioxidant. The compositions are formulated in a ready-to-mix formulation.
