AGROCHEMICAL MICROCAPSULES WITH A SHELL OF POLYVINYLALCOHOL AND POLYOXAZOLINE

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