The present invention relates to microcapsules comprising a capsule core and a capsule shell wherein the capsule shell comprises a core surrounding layer of a polyvinyl alcohol and an adjacent layer of a polyoxazoline, and wherein the capsule core comprises a water-insoluble pesticide. The invention further relates to a process for producing the microcapsule, comprising the process steps: a) preparation of an oil-in-water emulsion with a disperse phase which comprises the pesticide and an aqueous continuous phase and the polyvinyl alcohol, and b) subsequent addition of one or more of the polyoxazoline; and it relates to a method of controlling phytopathogenic fungi and/or undesired plant growth and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the microcapsules are allowed to act on the respective pests, their environment or the crop plants to be protected from the respective pest, on the soil and/or on undesired plants and/or on the crop plants and/or on their environment. |
