Abstract

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 C12-15 alkyl 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 GA3 or GA4A7 as well as in storage stability by adding an antioxidant. The compositions are formulated in a ready-to-mix formulation.

Description

FIELD OF THE INVENTION

[0001] The present invention is directed to soluble and stable liquid compositions including at least one plant growth regulator, at least one acid solubilizer, at least one surfactant adjuvant, and at least one solvent; as well as methods for making and using the compositions. The soluble liquid composition advantageously improves the preparation, the storage stability, the handler safety and the performance of a plant growth regulator formulation for spray application, as such composition is highly soluble in use dilutions, is easily metered, can be more highly concentrated and is dust-free. A presently preferred soluble liquid composition includes at least one plant growth regulator selected from the group consisting of an adenine cytokinin, an acid solubilizer selected from the group consisting of citric acid, tartaric acid and glycolic acid, a dilution solubilizer comprising a nonionic and / or anionic surfactant blend and a solvent comprising propylene gly...
