Biological Pest Control
Persian powder is a green pesticide that has been used for centuries for the biological pest extermination of household insects, garden pests, and agricultural pests. It is used indoors, in gardens and the horticulture industry, and in agriculture.
It is produced from the powdered flowers of certain species of Pyrethrum, in the genera Chrysanthemum and Tanacetum. In more recent times it has had formulations with brand names such as Zacherlin.

Famous quotes containing the words biological, pest and/or control:
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
“The pest of society is egotists. There are dull and bright, sacred and profane, coarse and fine egotists. ‘Tis a disease that, like influenza, falls on all constitutions.”
—Ralph Waldo Emerson (1803–1882)
“Imagine believing in the control of inflation by curbing the money supply! That is like deciding to stop your dog fouling the sidewalk by plugging up its rear end. It is highly unlikely to succeed, but if it does it kills the hound.”
—Michael D. Stephens. “On Sinai, There’s No Economics,” New York Times (Nov. 13, 1981)
