This product is insecticide and acaricide with low toxicity, no poiiution, no residue, widepest control spectrum, has high efficacy of bio-insecticide , suitable for vegetable of the mustard family. Its action mechanism is to intensify the effect of neurotransmitter, such as, glutamate and γ-amino butyric acid, make the latter lose function and disturb neurotransmission, after contacting the chemical quickly stops to eat and die. It is safe to human, animal and to environment as well, effective ingredients for a long time 10-15 days. Compare with Abamectin, its active higher in 1-3 times, reduce toxicity for warm-blooded animal.(equal to one-sixth of abamectin toxicity). Special for pests which become drug-fast to chemical insecticide or abamectin it has preventing efficacious.

Product Details:

GREEN CLAIM  is the 4”-deoxy-4”-methylamino derivative of abamectin, a 16-membered macrocyclic lactone produced by the fermentation of the soil actinomycete Streptomyces avermitilis.^[1][2] It is generally prepared as the salt with benzoic acid, emamectin benzoate, which is a white or faintly yellow powder.^[3] Emamectin is widely used in the US and Canada as an insecticide because of its chloride channel activation properties.^[4]

History

Emamectin, produced by the bacterium Streptomyces avermitilis, belongs to the avermectin family of compounds all of which exhibit toxicity for nematodes, arthropods, and several other pests. The benzoate salt of emamectin in particular has found widespread use as an insecticide and is approved by the EPA for use in prevention of emerald ash borer in ash trees.^[5] Emamectin is derived from avermectin B1, also known as abamectin, a mixture of the natural avermectin B1a and B1b. Emamectin has also shown promising applications in the eradication of fish lice and in fish farming.^[6] Emamectin was invented by Regina D. Leseota, Pradip K. Mookerjee, John Misselbrook, and Robert F. Peterson Jr. and patented on September 25, 2001, approved August 22, 2002.^[7] It was developed as a pesticide by Merck and Company and first marketed back 1997 in Israel and Japan.^[8]

Preparation

Emamectin is derived from abamectin by replacement of an epi-amino-methyl (NHCH₃) group by a hydroxyl (-OH) group at the 4”-position. Emamectin, like abamectin, is a mixture of two homologue compounds termed B1a and B1b which differ on the C-25 side-chain by one methylene (CH2) group. B1a contains a sec-butyl group while B1b has an isopropyl group. Emamectin is a mixture, typically consisting of 10% B1b and 90% B1a.^[9]

Avermectin biosynthesis is classified into three stages: the formation of the polyketide-derived initial aglycone, modification of the initial aglycone to produce avermectin aglycones, and glycosylation of avermectin aglycones to generate avermectins.^[10]
