    Abstract: The invention relates to an aqueous dispersion comprising microcapsules, the capsule wall of which is made of radically polymerised monomers and the capsule core of which comprises at least one oil and at least one lipophilic surfactant. The continuous phase of the dispersion comprises at least one agrochemical. The invention also relates to a method for producing an aqueous dispersion with the steps: i) provision of an aqueous dispersion comprising microcapsules, the capsule wall of which is made of radically polymerised monomers and the capsule core of which comprises at least one oil and at least one lipophilic surfactant (microcapsule crude dispersion), and ii) at least one agrochemical is added. The invention also relates to the use of the microcapsule crude dispersion for producing an aqueous dispersion and to a product comprising, as separate components, a microcapsule crude dispersion and at least one agrochemical for combined use in combating undesired plant growth and/or for controlling undesired insect or acaricide infestation of plants and/or for combating phytopathogenic fungi.

    Abstract: The present invention relates to a microemulsion, comprising (A) 0.1 to 50 wt.% of at least one active agent as component A, (B) 0.5 to 40 wt.% of at least one solvent that can be completely mixed with water and selected from the group consisting of esters from acetic acid, lactic acid, benzoic acid, dicarboxylic acids, cyclic esters, cyclic amides, carbonates, sulfurous solvents, phosphates, ethers and mixtures thereof, as component B, (C) 10 to 40 wt.% of at least one non-ionic surfactant as component C, (D) 0 to 10 wt.% further additives as component D, (E) 10 to 90 wt.% water as component E, and (F) 0.1 to 60 wt.% of at least one solvent that can be partially mixed with water as component F, each in relation to the entire microemulsion, wherein the sum of the amounts of components, A, B, C, D, E, and F is 100 wt.%, and the microemulsion does not comprise any anionic surfactants. The invention further relates to a method for the production of said microemulsion and to the use of said microemulsion for treating plants.

    Abstract: The present invention relates to a microemulsion comprising (A) 0.1 to 50% by weight of at least one active ingredient as component A, (B) 0.5 to 40% by weight of at least one solvent which is fully miscible with water, being chosen from the group consisting of esters of acetic acid, of lactic acid, of benzoic acid, of dicarboxylic acids, cyclic esters, cyclic amides, carbonates, sulphur containing solvents, phosphates, ethers and mixtures thereof, as component B, (C) 10 to 40% by weight of at least one nonionic surfactant as component C, (D) 0 to 10% by weight of further additives as component D, (E) 10 to 90% by weight of water as component E and (F) 0.1 to 60% by weight of at least one solvent which is partially miscible with water, as component F, in each case based on the total microemulsion, where the total of the amounts of components A, B, C, D, E and F is 100% by weight and where the microemulsion does not comprise any anionic surfactants, and to a process for the preparation of this microemulsion and to the use of this microemulsion for the treatment of plants.
