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.
