FIELD: chemistry.SUBSTANCE: composition contains an organophosphorous compound and phenyl pyrazol in the form of a solution thereof in mixed alcohols. The above organophosphorous compound is (1-hydroxy-2,2,2-trichloroethyl)-O,O-dimethylphosphonate, whereas phenyl pyrazol is -(±)-5-amino-1-(?,?,?-trifluoro-2,6-dichloro-n-tolyl)-4-trifluoromethyl sulphinyl pyrazol-3-carbonitryl in ratio 10:1. The low-molecular alcohols are specified in ethanol, propyl alcohol and/or isopropyl alcohol. The high-molecular alcohols are specified in ethylene glycol and/or propylene glycol. The total content of the active substances relates to the total contents of the alcohols as approximately 1:2. The optimum content of the active substances in the composition makes 27.5 wt %.EFFECT: higher insecticidal efficacy.2 cl, 1 dwg, 1 tbl |
