[Efficacy, toxicity and mechanism of insecticide KR-100: a preliminary study]

KR-100 is a newly developed long-lasting insecticide that incorporates cinerins substance, drug-release control substance and synergistic agent following certain procedures under carefully regulated conditions. Tests of the efficacy, toxicity, stability and long-term effect of KR-100 were conducted, and it was show that the insecticide possessed strong and long-lasting effect against mosquitoes, flies and cockroaches but was by no means toxic to human. Morphological study of KR-100 under scanning electron microscope revealed porous membrane form. This insecticide, therefore, can be safely applied with good pesticidal effect.
