Pyrethrum contains 0.6-1.3% of pyrethrin and grimethrin in its flowers. Pyrethrin is a colorless viscous oily liquid. When mosquitoes come in contact with it, it will paralyze the nerves, be poisoned and die. Pyrethrum extract can not only kill mosquitoes, but also kill pests of crops, forests and fruit trees. Together with tobacco and poison ivy, it is collectively called the "three major botanical pesticides."
Pyrethrin is the main insecticidal ingredient in pyrethrum chrysanthemum. In recent years, the stability of pyrethrin, especially the light stability, has been greatly developed, which greatly promotes the application of pyrethrin in the control of agricultural pests. Since synthetic insecticides cause great pollution to the natural environment during production and use, and pyrethrins are obtained from planting, their extraction and use have little environmental pollution.
Because pyrethrum has fast decomposition, no residue, light odor, natural non-irritating, extremely low toxicity, wide insecticidal spectrum and remarkable repellent effect on pests, it has played a huge role in insect control in the food industry.
Pyrethrum is mainly used for the prevention and control of household hygiene pests, especially mosquitoes, flies, beetles and cockroaches. It can also be used directly to remove human ectoparasites. The effect is very ideal.
Pyrethrins can also be used in poultry breeding and the prevention and treatment of pet pests and parasites.
Pyrethrin is environmentally friendly, and it is widely used in various hotels, hotels, especially high-end conference venues and some specific environments, such as hospitals, schools, offices, supermarkets, parks, playgrounds, etc. The control objects include pests such as cockroaches, termites and fire ants.
