Title (EN) AGROCHEMICAL FORMULATION COMPRISING ENCAPSULATED PESTICIDE
(FR) FORMULATION AGROCHIMIQUE CONTENANT UN PESTICIDE ENCAPSULÉ
Abstract: front page image
(EN)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 C1-C24 alkyl 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.
(FR)La présente invention concerne une composition aqueuse contenant un pesticide A en suspension et des microcapsules comportant un cœur et une coquille, ledit cœur contenant un pesticide B et un solvant polaire aprotique B, et ladite coquille contenant du poly(méth)acrylate, comportant des esters alkyliques en C1 à C24 d'acide acrylique et/ou méthacrylique, de l'acide acrylique, de l'acide méthacrylique et/ou de l'acide maléique sous forme polymérisée. L'invention concerne, en outre, un procédé de préparation de ladite composition comprenant une étape consistant à mélanger le pesticide A, de l'eau et les microcapsules. L'invention concerne également lesdites microcapsules dont le cœur contient le pesticide B et un solvant A, le rapport pondéral entre le pesticide B et l'ensemble de tous les solvants présents dans le cœur variant de 1/1 à 1/10. Chaque microcapsule contient jusqu'à 7 % en poids de poly(méth)acrylate, sur la base de la quantité totale de tous les pesticides et solvants présents dans le cœur, ainsi que du poly(méth)acrylate.
