Pyrethrins

Use

Pyrethrins/pyrethrum are natural insecticides produced by certain chrysanthemum species of plants. in contrast, permethrin (‘per-meth-rin’) is a synthetic, man-made insecticide, whose chemical structure is based on natural pyrethrum. pyrethrum was first recognised as having insecticidal properties around 1800 in asia and was used to kill ticks and various insects such as fleas and mosquitoes. six individual chemicals have active insecticidal properties in the pyrethrum extract, and these compounds are called pyrethrins. pyrethrum are viscous, tan-coloured brown resins, liquids, or solids which inactivate readily in air. pyrethrum are soluble in organic solvents such as alcohol, kerosene, nitromethane, petroleum ether, carbon tetrachloride, and ethylene dichloride. a quick acting liquid insecticide especially suited for control of insect pests of vegetables, ornamentals, and exotic crops. the piperonyl butoxide ingredient is used to enhance the activity of the permethrin (synergist). pyrethrum has been used effectively to control insects for decades and is nonpersistent, decomposing rapidly in the environment.
