Chemical structure of Allethrin isomers Chemical structure of Permethrin isomers. A pyrethroid is an organic compound similar to the natural pyrethrins, which are produced by the flowers of pyrethrums (Chrysanthemum cinerariaefolium and C. coccineum).
The World Health Organization published in 2004 that "Prallethrin is of low mammalian toxicity, with no evidence of carcinogenicity" and "is very toxic to bees and fish but of low toxicity to birds." [2] Prallethrin is a member of the pyrethroid class of insecticides. Pyrethroids have historically been classified into two groups, Type I and ...
