A herbicidal composition is provided, the 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, said herbicidally active compound being other than a sulfonylurea, preferably fluroxypyr, in a polyhyrdric alcohol ester solvent system the microcapsules being suspended in a continuous phase of a polyhydric alcohol solvent system having suspended therein finely divided particles of one or more sulfonylureas. A method for preparing the composition comprises the steps of 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 thereby encapsulate the 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).
