FIELD: chemistry.
SUBSTANCE: invention relates to microencapsulation of water-soluble pesticide preparations used in agriculture. Microcapsules of water-soluble pesticide preparations are obtained using a physical-chemical nonsolvent deposition method. As the precipitation agent acetone is used and as the microcapsule shell polyvinyl alcohol is used. Microencapsulation is carried out in the presence of an E472c emulsifier. The weight ratio of said preparation, polyvinyl alcohol and said emulsifier is 1:5:0.02.
EFFECT: invention simplifies the process and increases mass output of microcapsules of the preparation.
