FIELD: agriculture.

SUBSTANCE: invention relates to stabilized liquid agrochemical compositions. Agrochemical composition of the liquid dispersion concentrate contains: (a) a continuous phase containing water and additives selected from propylene glycol and a chemical curing agent; and (b) at least one disperse phase containing a microparticle of a polymer matrix formed using epoxy monomers of diglyceride ether of neopentyl and/or diglyceride ester of resorcin and a curing agent of trimethylhexadiamine, characterized by hardness of more than 0.001 MPa and less than 6 MPa, on the surface of which there is a colloidal solid material selected from silicon dioxide or clay, which is present at the boundary with the continuous phase, and containing an agrochemical active ingredient distributed therein. Continuous phase can additionally contain at least one agrochemically active ingredient, and the active ingredient is in a state selected from a solution, an emulsion, a microemulsion or a suspension of microcapsules or particles. Method of producing an agrochemical composition of a liquid dispersion concentrate includes the following steps: a. dissolving or suspending at least one agrochemically active ingredient in a mixture containing epoxy monomers, diglyceride ester of neopentyl and/or diglyceride ester of resorcinol and a curing agent trimethylhexadiamine; b. combining said solution or suspension with an aqueous liquid containing water and an additive selected from propylene glycol and a chemical curing agent, a colloidal solid material selected from silicon dioxide or clay, and using mechanical mixing sufficient to form an emulsion from said solution or suspension; and c. curing a polymerisable mixture containing epoxy monomers, diglyceride ester of neopentyl and/or diglyceride ester of resorcinol and a curing agent trimethylhexadiamine, to obtain an aqueous liquid dispersion of microparticles of a polymer matrix, which contains at least one agrochemically active ingredient and a colloidal solid substance distributed on the surface of the polymer matrix microparticles, and where the polymer matrix microparticles have hardness of more than 0.001 MPa and less than 6 MPa.

EFFECT: agrochemical composition of the liquid dispersion concentrate can be used directly or with dilution for pest control or as plant growth regulators.
