Claim:
1. A method of treating a seed comprising applying an aqueous suspension concentrate composition to a seed, wherein the composition comprises: from about 5 to about 40% S-(+)-Abscisic acid suspended as micro particles wherein at least 90% of the micro S-(+)-Abscisic acid particles are less than 10 micrometers in diameter; (ii) from about 0.1 to about 1.0% of at least one non-ionic polymeric surfactant that is a difunctional block copolymer surfactant with terminal secondary hydroxyl groups; (iii) from about 0.5 to about 4.0% of at least one non-ionic polymeric surfactant that is a difunctional block copolymer surfactant with terminal primary hydroxyl groups; (iv) from about 0.5 to about 5.0% of at least one vinylpyrrolidone/vinylacetate copolymer wherein the molar ratio of vinylpyrrolidone to vinylacetate is from about 30:70 to about 70:30; (v) from about 5 to about 20% of at least one diol; (vi) from about 0.045 to about 0.2% of at least one polysaccharide or cellulose derivative; (vii) from about 0.01 to about 0.5% of polydimethylsiloxane; (viii) at least one preservative selected from the group consisting of methyl p-hydroxy benzoate, propyl p-hydroxy benzoate and potassium sorbate; (ix) at least one chelating agent selected from the group consisting of EDTA, EDTA salts, citrates and gluconates; and (x) at least one antioxidant selected from the group consisting of propyl gallate, ascorbic acid and its salts and tert-butylhydroquinone, wherein all percentages are based on the total weight of the composition.
