The invention relates to a method for producing aqueous polymer dispersions containing pesticides, having an average particle diameter of the dispersed particles of < 1000 nm, by radical polymerisation of an oil-in-water emulsion, whereby the oil phase contains at least one pesticide in at least one ethylenically unsaturated monomer. Said method consists of emulsifying a solution of at least one pesticide in at least one monomer in water, in the presence of at least one surface-active agent, in order to form a mini- emulsion having an average particle size of <500 nm and/or adding at least one pesticide during or after emulsification and subsequently radically polymerising the mini-emulsion. The invention also relates to the use of the thus obtained dispersions in order to combat harmful micro-organisms and/or to regulate the growth of plants and/or to combat undesired plant growth and/or to combat undesirable insects or accaride attacks and/or to combat phytopathogenic fungi and/or for treating seeds.

L'invention concerne un procédé de fabrication de dispersions polymères aqueuses contenant des pesticides, présentant une granulométrie moyenne de particules dispersées < 1000 nm, par polymérisation radicalaire d'une émulsion huile dans l'eau, dont la phase huileuse contient au moins un pesticide dans au moins un monomère à insaturation éthylénique. Ledit procédé consiste à émulsifier une solution d'au moins un pesticide dans au moins un monomère dans l'eau, en présence d'au moins un tensioactif, de manière à fabriquer une miniémulsion présentant une granulométrie moyenne < 500 nm et/ou à additionner un pesticide pendant ou après l'émulsification et à effectuer une polymérisation radicalaire de la miniémulsion. L'invention concerne également l'utilisation des dispersions ainsi obtenues pour la lutte contre des micro-organismes nuisibles et/ou la régulation de la croissance de plantes et/ou la lutte contre la croissance indésirable de plantes et/ou la lutte contre des attaques d'insectes ou d'acariens sur des plantes et/ou la lutte contre des champignons phytopathogènes et/ou le traitement de semences.
