PURPOSE:To provide the subject one pack type aqueous insecticide not having the problems such as the corrosion of containers and the lowering of the potency, by compounding dimethyl ether as a propellant with an aerosol raw liquid containing a specific pyrethroid series insecticidal component, a specified organic solvent and a buffer solution and having a specific pH. CONSTITUTION:The subject insecticide is obtained by compounding dimethyl ether as a propellant with a 7.0-9.0pH aerosol raw liquid containing (A) an insecticidal component comprising a specific pyrethroid compound such as 3- allyl-2-methyl-4-oxocyclopent-2-enyl chrysanthemate or a mixture thereof with a specified pyrethroid compound such as 3-phenoxybenzyl 2,2-dimethyl-3-(2,2- dichlorovinyl)cyclopropane carboxylate, (B) a specific organic solvent such as isopropyl alcohol and (C) a buffer solution. The insecticide can be used as such without shaking the insecticide, because the contained liquids are not separated even after stored for a long period under relatively high temperatures and the generation of corrosion on tin containers and the lowering of the insecticidal potency are not caused. |
