ABSTRACT:
A pre-mix insecticidal composition is disclosed that contains (a) 0.1-10% by weight of 2,4-dioxo-1-(2-propynyl)imidazolidin-3-ylmethyl chrysanthemate, (b) 2.5-50% by weight of a fatty acid ester of 16-19 carbon atoms; (c) 2.5-30% by weight of a sorbitan fatty acid ester; (d) 0.5-1% by weight of at least one alcohol selected from the group consisting of ethanol, 1-propanol, 2-propanol, ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, butylene glycol and glycerin; and (e) 40-93.5% by weight of a saturated hydrocarbon of 8-18 carbon atoms. This pre-mix insecticidal composition exhibits little, if any, precipitation when left to stand. It is sufficiently stable to be transported and is storage stable prior to formulating an insecticidal aerosol composition. A useful insecticidal aerosol composition contains 5-30% by weight of this pre-mix insecticidal composition, 40-85% by weight of water and 10-50% by weight of a propellant. The aerosol composition is stable, i.e. the separation into aqueous phase and organic phase occurs at a very low rate after shaking. A method for controlling harmful insects is also disclosed.
