ABSTRACT:
The insecticidal transparent emulsion of the present invention is obtained by mixing (A) at least one pyrethroidal insecticide as defined in the claims as an active ingredient; (B) a polar solvent containing mixed surface active agent containing at least one metal alkylbenzenesulfonate, at least one nonionic surface active agent having an HLB (hydro- and lipophilicity balance) of 10 to 18 and at least one polar solvent; and (C) water, so that the content of (B) in the mixture is equal to or more than that of (A) and 6% by weight or less and then diluting the resulting mixture. The insecticidal transparent emulsion of the present invention has the advantage that the solution state is unchanged even when the environmental temperature sharply moves up and down.
