Application
Mechanism of action:
Cause death by hindering motor nerve information transmission of harmful insect. It strengthens the affect of nerve matter, such as glutamic acid and the r - amino-butyric acid (GABA), thus causes massive chloride ions enter into the nerve cell,causes losing of cell function and disruption of nerve conduction, larvae stop eating food immediately after exposure to emamectin benzoate, lead toirreversible paralysis and die. It can be degraded in the earth quickly and not accumulated.
It's safe for environment. Absorbed by crops easily, and seep to epidermis, causes extension of validity.
Main preventing and controlling insects:
Mainly used to prevent and control harmful insects in Lepidoptera, Coleoptera, Homoptera, Mite. Widely used to prevent and control bollworm, cutworm of sugar beet, cole moth, cabbage caterpillar, armyworm, Mite, Prodenia litura(Fabricius) and so on harmful insects in many kinds of vegetables, fruit trees, tea, tobacco and cotton.
Function character:
This product is high effective, low poisonous and environment safety, it's a new kind of half synthesis antibiotic pesticide, has the function of stomach poison and contact insecticide. Effect of preventing and controlling under extremely low density also is obvious. It is secure for beneficial insect, person and livestock in conventional dosage. It has already been used widely in western nation. In home, it also applies widely to tobacco, tea and vegetables. It may formulate with majority of agricultural chemicals.
