FIELD: agriculture.

SUBSTANCE: oil dispersion with improved stability for protection of plants from weeds, insects or fungal pathogens comprises: a) an oily phase containing, with respect to the total composition from 200 g/l to 999 g/l of a solvent immiscible with water; and b) the dispersed active ingredient with a polymeric coating insoluble in oil, which constitutes, relative to the total composition from 1 g/l to 700 g/l. The oil dispersion is obtained by: a) grinding the active ingredient which is intended to cover, and preliminary dispersing it in an aqueous solution by means of wetting agents and dispersants; b) adding one or more polymers insoluble in oil to dispersion in a); c) removing water from the dispersion obtained in b) to obtain a dry solid matter; and d) dispersing the dry solid matter from c) by mixing in the oil phase containing a solvent and other inert ingredients, active ingredients or antidotes.
