http://npic.orst.edu/factsheets/cyfluthringen.pdf 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).
