Common Name: Pyrethrum extract                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             Pyrethrum Extract is a mixture of three naturally occurring, closely related insecticidal ester of chrysanthemic acid (cinerin I, jasmolin I and pyrethrin I) and three closely related insecticidal ester of pyrethric acid (cinerin II, jasmolin II and pyrethrin II). The three chrysanthemic acid esters are commonly identified as "pyrethrins I", and the three pyrethric acid esters are identified as "pyrethrins II". Collectively, the six esters are called "pyrethrins".                                                                                                                                                                                                                                                                                                                                 Commercially available pyrethrum extracts usually contain 20% or 50% total pyrethrins. Content shall not differ from that declared by more than + or - 5% of the declared content.
