Insecticide common pesticide ingredients

Insecticide common pesticide composition is mainly pyrethroid esters and other pyrethroids, the toxicity of human and livestock is small, mosquitoes, flies, cockroaches and other pests have excellent ** and fumigation. The household insecticides currently sold on the market are mainly pyrethroid aerosol insecticides. Generally, they have been used to fight against the action of the death of permethrin and deadly permethrin, insecticidal esters, etc., The compounded medicament has both a quick hitting effect and a strong killing effect, and the three take advantage of each other, greatly improving the insecticidal effect. However, pyrethroid insecticides are insoluble in water and require the use of organic solvents as dispersing media.

Most of the aerosol insecticides currently used in the market are highly efficient and low-toxic products. The main insecticidal compound pyrethroids account for only a few percent of zero and do not cause harm to the human body. Some aerosol insecticides are unpleasant because the butane, kerosene, and permethrin components in the aerosol insecticide have a large odor. Aerosol pesticides are often composed of pressure-resistant vessels (iron or aluminum cans), blow-off nozzles, liquid chemicals and propellants. When the nozzle is lifted, the propellant or the compressed gas is rapidly vaporized to generate a high-speed airflow to atomize and atomize the chemical liquid. Aerosol insecticides are oil-based, water-based two. The so-called oil-based, water-based, refers to the aerosol pesticide used by the solvent. Oil-based pesticides generally use kerosene as a solvent and have strong adhesion; water-based solvents generally use alcohol as a solvent, and they evaporate faster.
