A herbicidal composition comprising microcapsules containing a solution of at least one herbicidally active compound that is solid at room temperature and with a melting point below 190° C., other than a sulfonylurea, preferably fluroxypyr, in a polyhydric alcohol ester solvent system； suspended in a continuous phase having suspended therein finely divided particles of one or more sulfonylureas. A method for preparing the composition comprising i) providing a water-immiscible liquid phase comprising a polyhydric alcohol ester, an active compound that is solid at room temperature and with melting point below 190° C., and a first wall forming component； ii) providing an aqueous phase comprising water and, optionally, one or more surface active agents； iii) combining the water immiscible phase with the aqueous phase to form a dispersion of the water-immiscible phase in the continuous aqueous phase； iv) adding a second wall forming component to the resulting mixture, causing interfacial polymerization of the first and second wall forming components and encapsulating droplets of the water-immiscible phase； v) providing a suspension of a sulfonylurea in a polyhydric alcohol ester, optionally with one or more dispersants； and vi) combining the composition prepared in step (iv) with the composition prepared in step (v).
