Brief Introduction: 
The product is a semi-fermented and semi-synthesized insecticide of Avermectin kind. The intermediate emamectin is synthesized under certain conditions using AVM as material, then reacted with benzoic acid, and thus we get Emamectin Benzoate. 
Emamectin Benzoate is more effective than Emamectin against the insects Lepidoptera. Notably, it is the best insecticide against cotton bell worm (Helicoverpa armigera), cole miller (plutella xylostella Linnaeus), etc. Which have been tolerant with such insecticides as pyrethroids, organic phosphates. 
So, emamectin benzoate is an ideal substitute for high poisonous and high residual agricultural chemicals, also a kind of outstanding biological pesticide, which prevents and controls tolerantly harmful insects. Many agricultural chemicals factory use it as ideal technical for formulating and single medicament exploiting.

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 to irreversible 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, it's one kind of green agricultural chemicals.
