1. A stable liquid dispersion comprising:
at least one growth regulator which has a solubility in vegetable oil of about 0.1 wt % or less, wherein the growth regulator is a gibberellin or a prohexadione;
an organic hydrophobic carrier which comprises an alkyl ester of a fatty acid of a vegetable oil;
wherein the at least one growth regulator is insoluble or unstable in water, and is present in the liquid dispersion in an amount exceeding about 0.1 wt %;
wherein more than about 90% of the particles of said growth regulator have a particle size of between 1-7 μm;
wherein the dispersion further comprises an emulsifier which stabilizes the dispersion in the organic carrier, and which causes the concentrate to be water miscible and self-emulsifying when diluted in water in a suitable dilution;
wherein the emulsifier is non-ionic, and comprises at least one polyethoxy group;
wherein the growth regulator is present in an amount of about 4 wt % or more and about 30 wt % or less; and
wherein the dispersion contains less than about 0.4 wt. % water.
