Emamectin benzoate


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.

Animals Emamectin benzoate is partially metabolised but rapidly cleared (DT50 following oral dosing 34-51 h), indicating that it has no potential for bioaccumulation. Plants Metabolism has been investigated in lettuce, cabbage and sweet corn. It is non-systemic, and rapidly degrades in sunlight to various complex residues in which undegraded parent is the only significant residue. The residues were very low. Soil/Environment Rapidly degraded.

Usage: Emamectin benzoate was developed by Merck and Company. 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.

Application: Biochemistry Acts by stimulating the release of g-aminobutyric acid, an inhibitory neurotransmitter, thus causing paralysis. Mode of action Non-systemic insecticide which penetrates leaf tissues by translaminar movement. Paralyses the lepidoptera, which stop feeding within hours of ingestion, and die 2-4 dat. Uses For control of Lepidoptera such as armyworm, bollworm, cutworm, cole moth, cabbage caterpillar, Mite, Prodenia litura (Fabricius) and so on harmful insects in many kinds of crops including vegetables, fruit, brassicas, cotton, tobacco and pine trees.
