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.
Cuations: High toxic to aquatic livings such as fish. Also high toxic to bees. No mixing with alkaline substances. Rapidly degrade in light. Sealed tightly and stored away from light in a cool and dry place.
Specificateion: 70%, 80%, 90% technical grade(active ingredient).
