Abstract: The present invention relates to a composition comprising microcapsules, which comprise a polyurea shell and a core, wherein the core comprises pendimethalin and the shell comprises a polymerization product of a tetramethylxylylene diisocyanate, and a polyamine with at least three amine groups, and where the polymerization product comprises less than 5 wt % of further isocyanate monomers in polymerized form, based on the weight of the tetramethylxylylene diisocyanate; a method for preparing the composition comprising the steps of contacting water, the pendimethalin, the tetramethylxylylene diisocyanate, and the polyamine; and to a method of controlling undesired plant growth, wherein the composition is allowed to act on the soil and/or on undesired plants and/or on the crop plants and/or on their environment.

Abstract: The present invention relates to a composition comprising microcapsules, which comprise a polyurea shell and a core, wherein the core comprises a water-insoluble pesticide and the shell comprises a polymerization product of a tetramethylxylylene diisocyanate, an cycloaliphatic diisocyanate, and an aliphatic diamine; to a method for preparing the composition comprising the steps of contacting water, the pesticide, the tetramethylxylylene diisocyanate, the cycloaliphatic diisocyanate, and the aliphatic diamine; and 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 composition is allowed to act on the respective pests, 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.
