|Section2= |Section6= |Section7= }} Emamectin is the 4”-deoxy-4”-methylamino derivative of abamectin, a 16-membered macrycyclic lactone produced by the fermentation of the soil actinomycete ''Streptomyces avermitilis''. It is generally prepared as the salt with benzoic acid, emamectin benzoate, which is a white or faintly yellow powder. Emamectin is widely used in the US and Canada as an insecticide because of its chloride channel activation properties. ==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.〔 〕 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.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Emamectin」の詳細全文を読む スポンサード リンク
