Cyfluthrin and beta-cyfluthrin are two active substances differing only in their isomeric composition. While cyfluthrin consists of four enantiomeric pairs of diastereoisomers, beta-cyfluthrin represents the biologically more active diastereoisomers (isomers II and isomers IV). WebResults for each potential exposed subpopulation (of adults, children 1-6 years, and infants <1 year) were compared to the systemic absorbed dose NOAEL for cyfluthrin to provide estimates of MOE. The large MOEs for cyfluthrin clearly demonstrate a …
