SUBSTANCE: agrochemical concentrate has continuous phase that contains water. Phase also includes auxiliary oil-based substance that improves biological effect of agrochemical agent and hydrotrope, which is able to changeover auxiliary substance into soluble condition in mentioned continuous phase. Oil-based auxiliary substance is a liquid auxiliary substanace or mixture of auxiliary substances, which in absence of hydrotrope are not substantially in continuous phase, and ratio of oil-based auxiliary substance and hydrotrope is in the range from 1:10 to 10:1. Agrochemical concentrate is produced from water phase, oil-based substance and hydrotrope.
EFFECT: improved stability of concentrate.
