Emamectin benzoate Usage And Synthesis
Chemical Properties White Crystalline Powder
Uses A mixture of semi-synthetic Avermectins. Exists as the anhydrous and various hydrated forms having different crystal morphologies. Insecticide
Uses Insecticide.
Uses Emamectin benzoate is a second-generation avermectin insecticide highly effective against a broad range of lepidopteran larvae and certain other insects.
Metabolic pathway In laboratory studies, emamectin benzoate is relatively stable to aqueous hydrolysis (acid, neutral and alkaline) under dark conditions. Emamectin benzoate degrades extensively in soil via microbial action to multiple degradation products including the 8a-oxidation and 8a-hydroxylation products. CO2 and soil-bound residues were the major terminal residues which are incorporated into humic and fulvic acid fractions. In plants, emamectin benzoate degrades extensively to multiple polar components including the N-demethylated, N-formylated and conjugated products. Probably due to rapid elimination in faeces, the metabolic transformation of emamectin benzoate in animals is minimal. However, N-demethylation was observed as the major metabolic pathway. The hydrolytic, photolytic and overall metabolic pathways of emamectin benzoate in soils, plants and animals are presented in Schemes 1,2 and 3.
