US EPA OKs Sumitomo's momfluorothrin
The US EPA has approved five non-agricultural insecticides based on Sumitomo Chemical's new pyrethroid, momfluorothrin. Sumitomo's S-1563 and McLaughlin Gormley King's MGK29871 and MGK29872 combine momfluorothrin with the established pyrethroid, d-phenothrin. MGK29811 combines momfluorothrin with the established pyrethroid, cypermethrin, and MGK29831 combines momfluorothrin with the synergist, piperonyl butoxide. All are formulated as ready-to-use aerosols for indoor and outdoor spot and crack-and-crevice treatments in residential and commercial settings. They are for the control of a range of flying, crawling and stinging insects and other arthropod pests. The approvals were proposed in December 2014. The Canadian authorities recently approved four momfluorothrin-based products.
