[The insecticidal activity of the new combined dust Malcord]

A formulation of 0.5% Malcord dust, which contains carbofos and permethrin (a 1:1 ratio) as active agents, was designed and examined. LC99 against synanthropic insects by the active ingredient was 0.01-0.005 g/m2. The effective application rate of the dust ranged 5 to 10 g/m2 in the treatment of various objects. The residual insecticidal effect of the dust on the treated surfaces remained 1.5-2.0 months (depending upon the type of an object). The dust Malcord has been permitted by the health care authorities of the Russian Federation for its usage by specialists and the population.
