FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. The herbicidal long-acting composition for use in soil comprises a systemic herbicide Zellek super, the polymers of polyhydroxyalcanoates class as a carrier material, and dichloromethane as a solvent, in the following component ratio, wt %: herbicide 10-50%, PHA 48-83 %, solvent 2-7%. Two types of polymer are used: a homopolymer of 3-hydroxybutyric acid and copolymers of 3-hydroxybutyrate and 3-hydroxyvalerate with the monomer ratio in the copolymer from 100:0 to 80:20 mol. %. The herbicidal composition in the form of pellets or film is produced.
EFFECT: invention enables to improve the efficiency of weed control.
