摘要:A subject matter of the present invention is a process for the preparation of effect compound-comprising microparticles M comprising A) the formation of a crude suspension of microparticles A by means of enzymatic polyester synthesis in an inverse miniemulsion comprising enzyme, effect compound and polyester monomers; and B) the polymerization of wall monomers from the group consisting of ethylenically unsaturated monomers, polyisocyanates and polyepoxides in the crude suspension of microparticles A. Furthermore, the present invention relates to microparticles M which can be obtained by means of the process according to the invention and also to an agrochemical formulation comprising microparticles M. In addition, the present invention relates to the use of microparticles M prepared according to the invention as component in colorants, cosmetics, drugs, biocides, plant protection agents, fertilizers, additives for food or animal fodder, or auxiliaries for polymers, paper, textiles, leather, detergents or cleaners. Finally, the invention also relates to a method for combating undesirable plant growth, to a method for combating undesirable insect or acarid infestation on plants and/or for combating phytopathogenic fungi, and to seeds treated with the agrochemical formulation.
