Pureplant protection agent, easy to degrade, no residue, harmless to humans andanimals, the product environmental protection safety, no pollution, highefficiency, in line with green ecological agricultural production.
Naturalchrysanthemin see the light slowly decomposed into water and CO, so thepesticide or health insecticide prepared with its no residue after use, no sideeffects on humans and animals, is internationally recognized as the safestpollution-free natural insecticide
Sincepyrethrin is composed of six substances with insecticidal activity extractedfrom pyrethrin flowers, it has a good insecticidal effect, and insects are noteasy to produce resistance, and can be used to manufacture pesticides that killpests with strong resistance.
Pyrethrinhas the effect of paralyzing the central nervous system of insects, and it is acontact insecticide, so it kills insects quickly and is easy to be accepted byfarmers.
Itcan be used as a sanitary spray for home hygiene and insecticide, and can bewidely used as a pesticide for green vegetables, green fruit, green tea andother cash crops. Pyrethrin inhibits nerve tissue. It is insoluble in water andsoluble in a variety of organic solvents. Low toxicity to higher animals,
Althoughchrysanthemum is easy to cause dermatitis in production and use. Even specificallergies. However, this effect can be eliminated during the preparation of theproduct. It is toxic to aquatic life such as fish and bees. High insecticidalactivity. It is a nerve agent, mainly has a touch effect.
Pyrethrinhas two major functions of insecticide and environmental protection, which cannot be compared with any chemical insecticide.
Itsfeatures and advantages are:
(1)Low toxicity to mammals: pyrethrin is one of the least toxic products ofexisting pesticides, and it will be quickly metabolized even if accidentallyswallowed;
(2)High efficiency and broad spectrum: Because pyrethrin contains a group ofinsecticidal components with similar structure, it has high efficiency andbroad spectrum for insecticidal.
(3)Strong tactility, high fatality rate, and low concentration of use.
(4)Rapid action: pyrethrin has a rapid knockout, blocking valve lethal contacteffect.

Pyrethrinis prepared from the flower of pyrethrin cultivated by solvent extraction. Itis a perennial root plant in the asteraceae family. Pyrethrin (mainly found inflowers) is a typical nerve agent, the main components of which are pyrethrin Iand II. Luzica and H. Staudinger were separated. It has the functions oftactility, gastric toxicity and repellent, and can act on peripheral nervoussystem, central nervous system and other organs and tissues simultaneously.Strong knockout force against pests, wide insecticidal spectrum, lowconcentration of use, low toxicity to humans and animals, safe to plants andthe environment.
PyrethrinI: Molecular formula C21H28O3; It is a viscous liquid; Boiling point 146 ~ 150 ℃ (0.0005 mm Hg), specific rotation [α] -14° (isooctane); Insoluble in water,soluble in ethanol, petroleum ether, carbon tetrachloride, dichloromethane,nitromethane and other solvents; The median lethal dose was 1.2 g/kg (oraladministration in rats). The melting point of its semicarbazone derivatives is114 ~ 146 ℃ .Pyrethrin I is easily oxidized in the air and loses its insecticidal activity,so it must be refrigerated away from light.
PyrethrinII: molecular formula C22H28O5; It is a viscous liquid; Easy oxidation failurewhen exposed to air; Boiling point 192 ~ 193 ℃ (0.007 MMHG), (isooctane-ethyl ether); Its solubility, chemical properties andtoxicity are similar to pyrethrin I.

1.Insecticidal effect
Pyrethrinis toxic to a variety of insects such as mosquitoes, flies, bedbugs andcockroaches. Insect exposure to pyrethrin occurs within 1 to 2 minutes ofhyperexcitability, dyskinesia, and rapid knockout and paralysis.
Pyrethrinis a typical neurotoxin, which directly acts on excitable membranes,interfering with membrane ion conduction, mainly affecting sodium channels innerve membranes, delaying the disappearance of increased sodium conductionduring excitation, resulting in prolonged transmembrane sodium ion flow, causingrepeated activity of sensory nerve fibers and motor nerve axes, temporary nervecell depolarization and continuous muscle contraction. High concentration caninhibit ion conduction of nerve membrane and block excitation.
2.Toxic effects
Pyrethrinis very low toxic to mammals and is metabolized rapidly in the body, leavingvirtually no residue. But this is only when taken orally. Pyrethrin, givenintravenously, is highly toxic to mammals. Symptoms of poisoning in vertebratesare similar to those in insects, with hyperexcitability and tremors seen withinminutes of medication.

Controlfruit aphids, leafhopper and other pests, with 3% pyrethrin cream oil 22.5 ~37.5 grams/ha (active ingredient) mixed with water spray. Can also usepyrethrum pollen (dried flower crushed) l kg, neutral soap 0.6 ~ 0.8 kg, water400 ~ 600 liters after spraying. Methods: Dissolve the soap with a small amountof hot water, add pyrethrin powder, then add enough water, stir evenly afteruse, can control a variety of aphids, leaf nails, stink bug and other pests.
