Metofluthrin 93% (sumi one)

Metofluthrin  is an exciting novel pyrethroid discovered by Sumitomo Chemical Co., Ltd. 

It was registered in Japan in January 2005 and has now been under worldwide development for envi- ronmental health use. Metofluthrin has extremely high knockdown activity against various insect pests espe- cially mosquitoes, as well as relatively high volatility and low mammalian toxicity. This is applicable to not only existing formulations and devices such as a mosquito coil and a liquid vaporizer, but also various new type products such as a fan vaporizer, a paper emanator and a resin emanator. It is noted that knockdown activity of Metofluthrin is more than 40 times higher than that of d-allethrin against southern house mosqui- toes in a mosquito coil formulation. This paper describes the discovery story, insecticidal efficacies in various formulations, synthetic methods and safety evaluations of Metofluthrin.
