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
