Pyrethrum
Natural purified pyrethrum concentrate is a natural product obtained from chrysanthemum flowers, which is effectively used as an insecticide. The effectiveness of pyrethrum is due to its content of six complex esters, primarily pyrethrin 1 and pyrethrin 11, as well as cinerin 1 and cinerin 11, jasmolin 1 and jasmolin 11
