<p>An agrochemical composition is provided, the composition comprising at least one benzoylphenyl urea active ingredient, a solvent comprising a C2-C4 dialkylene glycol di-/mono- C1-C4 alkyl ether; and optionally at least one component selected from the group consisting of a surface-active agent, a thickener, an antifoam agent, an antifreeze agent and water. The presence of the C2-C4 dialkylene glycol di-/mono- C1-C4 alkyl ether reduces the crystallization of the benzoylphenyl urea active ingredient during storage and use, while also reducing the phytotoxicity of the formulation. A method of preparing the formulation, in particular an EW formulation comprises (1) mixing one or more pesticidally active benzoylphenyl ureas with one or more C2-C4 dialkylene glycol di-/mono- C1-C4 alkyl ethers to form a homogeneous oil phase; (2) mixing one or more additives selected from a surface-active agent, a thickener, an antifoam agent, an antifreeze agent and water; and (3) combining the water phase and the oil phase to form a dispersible EW emulsion formulation.</p> |
