Abstract
The present invention relates to a aqueous composition containing a suspended pesticide A, and microcapsules comprising a shell and a core, wherein the core contains a pesticide B and an aprotic, polar solvent B, and the shell contains poly(meth)acrylate, which comprises C-Calkyl esters of acrylic and/or methacrylic acid, acrylic acid, methacrylic acid, and/or maleic acid in polymerized form. The invention further relates to a method for preparing said composition comprising the mixing of the pesticide A, water and the microcapsules, to said microcapsule, wherein the core contains the pesticide B and a solvent A, wherein the weight ratio of the pesticide B to the sum of all solvents in the core is from 1:1 to 1:10, and wherein the microcapsule contains up to 7 wt % poly(meth)acrylate, based on the total amount of all pesticides in the core, all solvents in the core, and the poly(meth)acrylate.
