[Insecticidal properties of sumitrin]

The study of insecticidal properties of sumitrin demonstrated that in contact action it was a highly effective insecticide; in topical application LD50 for domestic flies, bedbugs and cockroaches was 0.47, 1.25 and 3.26 mug/g, respectively. Sumitrin possessed high action selectivity for insects and low toxicity for warm-blooded animals (LD50 for albino mice greater than 7500 mg/kg). In the form of aerosols sumitrin and its mixtures with DDVF were less active than compositions on the neopinamine base.
