Product Description

1.Brief Introduction:
Pyrethrins is known as natural pyrethroids. It is an active ingredient with insecticidal effect extracted from Pyrethrum cineriifoliun Trebr. It consists of pyrethrin I, pyrethrin II, cinerin I, cinerin II, jasmin I, and jasmin I.

Pyrethrins is extracted from the flowers of pyrethrums by solvent extraction. Pyrethrin (mainly present in flowers) is a typical nerve poison, the main components of which are pyrethroids I and II. It was isolated by L. Luzhika and H. Staudinger in 1924.". It has a touch killing, gastric toxicity, and repellent effect, and can simultaneously act on the peripheral nervous system, central nervous system, and other organs and tissues. Strong knockdown power against pests, wide insecticidal spectrum, low concentration of use, low toxicity to humans and livestock, and safe for plants and the environment.

Pyrethrin I: molecular formula C21H28O3; Is a viscous liquid; Boiling point 146~150 ºC (0.0005 mm Hg), specific rotation She-14 ° ; Insoluble in water, soluble in ethanol, and other solvents; The median lethal dose is 1.2 g/kg (orally administered to rats). Its biuret derivative has a melting point of 114 to 146 ºC. Pyrethrin I is easily oxidized and loses its insecticidal activity when exposed to air, so it must be kept away from light and refrigerated.

Pyrethrin II: Molecular formula C22H28O5; Is a viscous liquid; Exposure to air is prone to oxidation failure; Boiling point 192~193 ºC (0.007 mm Hg) Hazard+14.7 ° ; Its solubility, chemical properties, and toxicity are generally similar to those of pyrethroid I.
