FIELD: chemistry.

SUBSTANCE: invention relates to an aqueous composition containing particles coated with at least one non-amphoteric quaternizable polymer that is water-soluble at 20°C, and at least one dispersing component. The dispersing component contains a dispersing agent selected from amphiphilic grafted polymer based on water-soluble polyalkylene oxides (A) as a base for grafting, and side chains formed by polymerization of a vinyl ester component (B). The specified polymer has an average of ≤1 grafting site per 50 alkylene oxide units and average molar weights Mw from 3000 to 100000. The aqueous composition is used to obtain an agrochemical composition.

EFFECT: invention makes it possible to improve the stability of surface-modified particles in aqueous compositions and to ensure the controlled release of the active component after applying the agrochemical composition.
