Webcyfluthrin is an enrichment of these isomers resulting in a product with about 97% of the two most insecticidally active isomers (Reference 4). The EPA expects that the environmental fate and ecological effects of cyfluthrin and beta-cyfluthrin are similar, so they used data for cyfluthrin whenever specific data for beta-cyfluthrin was lacking. WebMar 1, 2024 · We decided to focus on these “realistic” concentrations because it has been documented that these concentrations are within the range of the derived NOAEL values from oral acute and subchronic neurotoxicity studies performed in rats for cyfluthrin and alpha-cypermethrin according to EU Regulation No 528/2012 from 2012 to 2016. flo fly girl lyrics

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).
