FIELD: agriculture. SUBSTANCE: invention describes method of producing microspheres containing agriculturally active substance. Method involves preparing liquid phase containing liquid agriculturally active substance, mixing obtained liquid phase with aqueous phase containing polyvinyl alcohol and preparing emulsion followed by drying by spraying for incapsulating agriculturally active substance. For mixing liquid phase containing liquid agriculturally active substance aqueous phase containing from 1 to 25 wt.-% of polyvinyl alcohol is used. Then mixture of finely dispersed clay is added to obtained emulsion in the amount from 5 to 40 wt.-% relative to mixture. EFFECT: high quality of microspheres, good dispersible properties in water for spraying. 11 cl, 4 ex
