High-efficiency cypermethrin, also known as kung fu permethrin, is one of the pyrethroid pesticides.
Pyrethroid insecticides came out in the 1970s, this type of insecticide has the characteristics of low toxicity, high efficiency and easy to be decomposed in the environment, is widely used in agriculture and sanitary pest control worldwide, and is also the world's most used insecticide.
Pyrethroids are a class of synthetic pyrethroid analogues, which have the advantages of fast knocking down pests, strong photostability, high efficiency, broad-spectrum insecticidal activity, and easy degradation. Compared with other pesticides, it is less toxic to humans and animals, and can be used to effectively prevent pests that are resistant to organophosphorus and carbamates, but its disadvantage is that pests are easily resistant to them.
Pyrethroid compounds have the effect of contact killing and gastric toxicity, and do not have aspiration activity. The peripheral and central nervous systems of insects are the main areas of action of pyrethroid-like drugs, and their mechanism is to cause paralysis of agricultural pests by stimulating nerve cells; in addition, it can quickly paralyze the muscles of insects and has excellent knockdown activity.
High-efficiency cypermethrin is a new generation of type II broad-spectrum high-efficiency pyrethroid insecticide insecticides, with stronger toxicity, faster efficacy, with a wider insecticidal spectrum and higher insecticidal activity. The effect of disease and pest control on vegetables, cotton, fruit trees and other crops is remarkable, and the killing speed of vegetable pests is relatively fast. High-efficiency cypermethrin has a certain anti-effect on pests and mites of the suction mouthpiece. In the early use of mites, can inhibit the rise in the number of mites, when the mites have occurred in large quantities, it can not control its number, so it can only be used for the treatment of mites, can not be used as a special acaricide. Since high-potency cypermethrin does not have an aspirational activity, it can be used with an assortive insecticide to enhance efficacy. Such as chrysanthemum insecticides imidacloprid, thiamethoxam, etc. to improve the control effect of pests such as aphids and thrips. With a vitamin salt, indigod, etc., it improves the prevention effect of pests such as vegetable green insects and corn borers.
High-efficiency cypermethrin has light stability under natural light exposure, its affinity for plants and particles is high, and it is easy to leave a large amount in the environment. Cypermethrin is fat-soluble, and frequent and excessive use of Cypermethrin carries some risk to non-target organisms.
