About Pyrethrum Insecticides
PyGanic® Pyrethrum is a botanical insecticide produced primarily in the flowers of Tanacetum cinerariaefolium, a species of the chrysanthemum plant family.
The insecticide properties of Pyrethrum were documented in the early 1800’s but it is suspected that the flowers were used to kill insects a considerable time earlier. The first commercially available products were powders made from ground flowers and later crude oil extractions became popular. Today, the refining of crude pyrethrum extract to remove the plant material, waxes, etc. is a highly complex process resulting in a very pure product from which most other plant properties have been removed.
Pyrethrum has been used effectively to control insects for decades and is non-persistent, decomposing rapidly in the environment. This rapid degradation of pyrethrum has resulted in little known cases of insect resistance making it an excellent choice for the control of insects in a wide variety of settings.
From a toxicological viewpoint, pyrethrum has been extensively studied. It is low in acute toxicity to man and other vertebrate animals.
PyGanic® Pyrethrum is compliant with the USDA's National Organic Program (NOP) requirements for an organic input. PyGanic is OMRI listed® and is an approved material under Washington State Department of Agriculture organic food program.
