A herbicidal composition comprising an aqueous suspension of microcapsules is provided. The microcapsules have a capsule wall of a porous condensate polymer, wherein the microcapsules contain a solution of clomazone in a solvent system comprising one or more non-edible oils. A method for preparing the composition comprises providing a water immiscible phase comprising clomazone, an isocyanate and optionally an ACD cross-linker, dissolved in a solvent system comprising a non-edible oil; providing an aqueous phase comprising one or more surfactants; combining the water immiscible phase and the aqueous phase to form a dispersion of the water immiscible phase in the aqueous phase; thereby forming microcapsules of polyurea containing droplets of the water immiscible phase; and curing the microcapsules.
A herbicidal composition comprising an aqueous suspension of microcapsules, the microcapsules having a capsule wall of a porous condensate polymer, wherein the microcapsules contain a solution of clomazone in a solvent system comprising one or more oils, wherein the oil is selected from the group consisting of Neem oil, Pyrethrum oil, Sesame oil, and Clove oil, and wherein the walls of the microcapsules are formed from a polyurea formed by the interfacial polymerization of an isocyanate and optionally an ACD cross-linking agent.
