like, slightly soluble in water, insoluble in

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.
