Pyrethrum (Tanacetum cineraiifolium) is a perennial plant in the family of Asteraceae which is cultivated for the production of six closely related esters called pyrethrins, which possess insecticidal properties. Pyrethrins can be separated into two groups of three ester compounds: pyrethrin I and II. The pyrethrin I fraction contains chrysanthemic acid products, including pyrethrin I, cinerin I, and jasmolin I. The pyrethrin II fraction is derived from pyrethric acid made up of pyrethrin II, cinerin II, and jasmolin II. Using natural pesticide may lead to organic farming, and advantage of organic farming is more beneficial to biodiversity and the environment, and of course organic produce reduces dietary exposure to pesticides. Organic farmers can use pyrethrins as an insecticide for fruit and vegetable crops. Easily degraded by oxygen, light and temperature, pyrethrum compounds are environmentally friendly and compatible with organic farming.
