Abstract:
The present invention relates to a method for preparing an emulsifiable granule comprising the steps of a) emulsifying water with a solution of a pesticide in a water-insoluble solvent, b) contacting the emulsion resulting from step a) and a solid dispersant containing a water-soluble polycarboxylate and a water-soluble anionic surfactant, and c) extruding the paste resulting from step b). The invention further relates to emulsifiable granules containing a water-insoluble solvent, a pesticide, which is dissolved in the water-insoluble solvent, a water-soluble polycarboxylate, and a water-soluble anionic surfactant.
Abstract:
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 °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.
