herbicidal compositions. a herbicidal composition is provided, and comprises microcapsules containing a solution of at least one herbicidally active compound, which is solid at room temperature, and has a melting point below 190 ° C, said herbicidally active compound being different. of a sulfonylurea, preferably fluroxipyr, in a polyhydric alcohol ester solvent system； the microcapsules being suspended in a continuous phase of a polyhydric alcohol ester 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 which is solid at room temperature, and which has a melting point below 190 ° C. <；198>； cm and a first wall forming component； ii) providing an aqueous phase if it comprises water and optionally one or more surfactants； 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, thereby encapsulating the water-immiscible phase droplets； v) providing a sulfonylurea suspension in a polyhydric alcohol ester, optionally with one or more dispersing agents； and vi) combining the composition prepared in step (iv) with the composition prepared in step (v).composições herbicidas. uma composição herbicida é fornecida, e compreende microcápsulas contendo uma solução de, pelo menos, um composto herbicidicamente ativo, que é sólida pa temperatura ambiente, e possui um ponto de fusão abaixo de 190 <；198>；c, o referido composto herbicidicamente ativo sendo diferente de uma sulfonilureia, de preferência, fluroxipir, em um sistema solvente de éster de álcool poli-hídrico； as microcápsulas sendo suspensas em uma fase contínua de um
