Emamectin Benzoate is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized from the fermented product Abamectin B1. It has the characteristics of super high efficiency, low toxicity (nearly non-toxic preparation), low residue, and pollution-free biological pesticides. It is widely used for the prevention and control of various pests on vegetables, fruit trees, cotton and other crops.

This product is highly effective, broad-spectrum, and has a long residual effect. It is an excellent insecticide and acaricide. Its mechanism of action hinders the transmission of pests' motor nerve information and causes the body to paralyze and die. The mode of action is gastric poison, which has no systemic effect on crops, but it effectively penetrates into the epidermal tissue of the applied crops, so it has a longer residual effect period. It also has high activity for the prevention and control of cotton bolls, mites, coleoptera and homopteran pests, and does not cross with other crops. It is easily degraded in the soil and has no residue, and does not pollute the environment. It is within the range of conventional doses. It is safe for beneficial insects and natural enemies, humans and livestock, and can be mixed with most pesticides.

- Biochemistry:

Acts by stimulating the release of g-aminobutyric acid, an inhibitory neurotransmitter, thus causing paralysis.

- Mode of Action:

It penetrates the non-systemic insecticides of leaf tissues through cross-layer movement, paralyzing lepidopteran insects, stopping eating within a few hours after ingestion, and dying after 2-4 days.

- Uses:

For control of Lepidoptera on vegetables, brassicas and cotton, at up to 16 g/ha, and in pine trees, at 5-25 g/ha.
