摘要

Microcapsules, Methods for Preparing Microcapsules and Controlling Phytopathogenic Fungi and Aqueous Composition The present invention relates to microcapsules comprising a shell and a polyurea core containing a pesticide, a water-immiscible solvent and at least 0.5% by weight of a polar and aprotic solvent having a water solubility of 0.5 to 20 g / l at 20 ° C based on the total weight of the solvents in the core. The present invention also relates to microcapsules comprising a shell and core containing a pesticide and 2-heptanone; to a method for preparing said microcapsules, to an aqueous composition comprising said microcapsules; and a method for controlling phytopathogenic fungi and / or undesirable plant growth and / or undesirable attack by insects or mites and / or for regulating plant growth with said microcapsules.
