FUNCTION

Pyrethroid is the dry inflorescence of pyrethroid, which contains about 1% pyrethroids. It has the advantages of good insecticidal efficacy, quick knockdown and low toxicity. In recent years, synthetic pyrethroid analogues have many advantages, such as broad insecticidal spectrum, low toxicity to human and livestock, less environmental residues and so on. This kind of insecticide belongs to nerve agent. Although pyrethrin is a low toxic insecticide, its toxicity can be significantly enhanced or the half-life of the drug can be prolonged when combined with other insecticides, such as pyrethrin and propranolol. This kind of insecticide has strong inhalation toxicity.

Pyrethroids are the main raw materials for the preparation of mosquito repellent incense. They are the insecticidal active ingredients in pyrethrum, a perennial herb of Compositae. There are mainly pyrethroids I and II, in addition, there are a small number of similar structures of pyrethroids I and II. Pyrethrin is a yellow viscous oily liquid with a delicate smell. Insoluble in water, soluble in a variety of organic solvents. It is unstable. It will decompose and fail in case of alkali. It will also decompose and fail in strong light or high temperature. The main dosage forms are powder, emulsifiable concentrate, aerosol, oil, mosquito repellent incense, etc. It has strong contact killing effect and wide insecticidal spectrum. The residual period is short. It is mainly used to control health pests, livestock pests, etc. It is a kind of botanical pesticide which is very safe for human and livestock, has no harm to plants, no residue, and does not pollute agricultural products and environment. Safe for warm blooded animals. The toxicity of pyrethrin I to insects was the strongest, followed by that of leaf pyrethrin, followed by that of leaf pyrethrin II, and that of leaf pyrethrin II was the weakest.

APPLICATION

Pyrethroid is a broad-spectrum insecticide that can control a variety of pests. Its insecticidal virulence is 10 to 100 times higher than that of the older generation of insecticides such as organic chlorine, organic phosphorus and carbamate. Its mechanism of action is to disrupt the normal physiology of the insect nerves, causing them to die from excitement, paralysis and paralysis. Pyrethroids are safer for humans and animals due to their small dosage and low concentration, and have little environmental pollution.
