A liquid dispersion comprising (i) at least one growth regulator which has a solubility in vegetable oil of about 0.1 wt% or less; (ii) an organic hydrophobic carrier; wherein the at least one growth regulator which is insoluble or unstable in water and is present in the liquid dispersion in an amount exceeding 0.1 wt%; and wherein more than 90% of the particles of said growth regulator has a particle size of between 1-7 µm; wherein the dispersion further comprises (iii) 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, such as for example a 1:50 dilution or higher dilution; wherein the dispersion is essentially water free. Preferably the growth regulator is a gibberellic acid (GA-3) or a prohexadione-calcium salt, and the hydrophobic carrier is a vegetable oil, hydrocarbon oil or paraffin oil, or a derivative thereof. Also claimed is a water based spraying liquid suitable for spraying plants, wherein the liquid comprises water and a suitable amount of the dispersion. |
