Avermectin is the new type of anti-acarid antibiotic, which is distilled after microbial ferment, B1a is the most active content of it and has a very good effect on anti-acarid and other pests, so it has the feature of "broad-spectrum, high efficient, low residual and easy use". So currently it is one of the most ideal biological pesticides and insecticides. Avm to kill pest through stomach poisoning (mastication insects and stick & suck insects) and contact poisoning (avm can enter into body through insects' stoma and claw) , it blocks the nerve conduct system of insects to paralysis and dyed. Avm can be decomposed by light and microbe, and can be absorbed into the body of plant by its roots, so it is safe to the environment.
