PURPOSE:To obtain an insecticidal aqueous liquid agent having solution stability by solubilizing a water insoluble pyrethroid based insecticidal ingredient into water using a surfactant consisting of a metal salt of alkylbenzene sulfonic acid, non-ionic surfactant and polar solvent. CONSTITUTION:The aimed insecticidal aqueous liquid agent containing one or more kind of pyrethroid based insecticides selected from a group of phenothrin, allethrin, terallethrin, prallethrin, etc., or the above-mentioned pyrethroid based insecticide and further one or more kind of pyrethroid based insecticide selected from a group of siphenothrin and phenpropathrin, etc., as active ingredients and consisting of a metal salt of alkylbenzene sulfonic acid, nonionic surfactant having 10-13 HLB and porous solvent as a mixed surfactant containing the porous solvent, being <=6wt.% in content of mixed surfactant containing the porous solvent in a solvent and containing same weight as active ingredients. The aimed agent is stable in solubility to temperature change which is important in quality. |
