Botanical pesticide additives pyrethrum extract is a kind of broad-spectrum pesticide that can control many kinds of pests, and its insecticidal toxicity is 10-100 times higher than the old generation pesticides such as organochlorine, organophosphorus and carbamate. Pyrethroids have a strong contact killing effect on insects, and some varieties have both stomach poisoning or fumigation effects, but none of them have systemic effects. Its mechanism of action is to disturb the normal physiology of nerve insects, causing them to die from excitement, spasm, and paralysis. Due to the small dosage and low concentration of pyrethroids, it is safer for humans and animals and has little pollution to the environment. The main disadvantage is that it is highly toxic to fish, and it is also harmful to some beneficial insects. long-term repeated use will also cause pests to develop drug resistance.
Pyrethrin is usually extracted at low temperature, and its processing technology is as follows:
Dried flower granulation - subcritical biotechnology low temperature extraction - solvent recovery - pyrethrin products.

Phrethrum the roots, stems, leaves and flowers of pyrethrum contain toxin substances, which are the raw materials for extracting pyrethrins and are good raw materials for formulating various pesticides. mosquito coils made of pyrethrum leaves can kill mosquitoes and flies, and have special effects on bedbugs, lice and fleas. Pyrethrum does not pollute the environment, does not destroy the ecological balance, has no drug resistance, and is non-toxic to humans, livestock, poultry and mammals.
A pot of 4 square meters indoors can play a role in repelling mosquitoes and flies, and the effect is very obvious. It can effectively inhibit pests from entering the orchard and reduce the harm of using chemical pesticides. The stems of pyrethrum can also be chopped and buried in the ground in late autumn to kill overwintering pests.
Planted in pyrethrum farms, in cattle, sheep, pigs, chickens, and farms, an average of 4 square meters of pyrethrum can repel mosquitoes and flies in the farm. The dried pyrethrum product is crushed and sprinkled into the pens, so that the livestock and poultry will not have lice, fleas, bed bugs and other parasites. In summer, the flies and maggots can be controlled to prevent the spread of diseases.
