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.

Agrochemical formulation comprising encapsulated pesticide

The present invention relates to microcapsules comprising a polyurea shell and a core, which contains a pesticide, a water-immiscible solvent A and at least 5 wt % of an aprotic, polar solvent B, which has a solubility in water from 0.5 to 20 g/l at 20&#xb0; C., based on the total weight of the solvents in the core. It further relates to microcapsules comprising a shell and a core, which contains a pesticide and 2-heptanone; to a method for preparing said microcapsules; to an aqueous composition comprising said microcapsules; and to a method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants, with said microcapsules.

Microcapsules of the present invention have a core and a wall. The wall is made of a polymer, which by weight is from 40 to 90% C-C-alkyl ester of acrylic acid, methacrylic acid, or both ('first monomer'); from 10 to 60% an ethylenically unsaturated crosslinker; and from 0 to 30% an ethylenically monounsaturated monomer different from the first monomer. At least 80% of the crosslinker is has three or more ethylenically unsaturated radicals. The core is made of a paraffin composition, which by weight has from 35 to 98% n-octadecane; from 1 to 10% C-C-aliphatic, diisopropylnaphthalene, or both; from 1 to 5% wax with a melting point &#x3e;40&#xb0; C.; and from 0 to 50% n-hexadecane. The present invention also relates to a process for preparing the microcapsules and to their use in binding construction materials, textiles, and heat transfer liquids.

Microcapsules with a paraffin composition as capsule core

The present invention relates to microcapsules comprising a capsule core and a capsule wall, where the capsule wall is constructed from
