        Structural formula:
        Emamectin Benzoate

        Physicochemical property
        Properties: The original drug is white or light yellow crystalline powder.
        Melting point: 141-146 ℃
        Solubility: Soluble in acetone and methanol, slightly soluble in water, insoluble in hexane.
        Stability: Stable under normal storage conditions.

        Compared with abamectin, the insecticidal activity of it raised the first 3 orders of magnitude, the pest lepidoptera insect larvae, and many other high activity, stomach toxicity effect and tag it, at very low doses (0.084 ~ 2 g/ha) has good effect, and in the process of prevention and control of insect pests of beneficial insects without damage, is conducive to the comprehensive prevention and control of pests, In addition, the insecticidal spectrum was expanded and the toxicity to human and animal was reduced.

        Use One: the goods is the only thing that can replace the 5 kinds of high toxic pesticides by the means of new type, high efficiency, low toxicity, safe, pollution-free, no residue of biological pesticide acaricide. The highest activity, insecticidal spectrum wide, no resistance. It has stomach-toxic and tentacle-killing effects. The highest activity against mites, lepidoptera and coleoptera pests. If used in vegetables, tobacco, tea, cotton, fruit trees and other cash crops, with other pesticides incomparable activity. In particular, it has super high efficiency against insect pests such as red belt leaf curling moth, tobacco aphiditis, diamondback moth, sugar beet leaf moth, cotton bollworm, tobacco leaf moth, dry-land gluttonia moth, consonance moth, vegetable mealworm, cabbage cross stripe moth, tomato root moth, potato beetle and so on.
        Use Two: Widely used in vegetables, fruit trees, cotton and other crops on the control of a variety of pests.
        Use Three: This product has the characteristics of high efficiency, broad spectrum, safety and long residual effect. It is an excellent insecticide and acaricidal agent. It has very high activity against Lepidoptera pests, mites, Coleoptera and Homoptera pests, and it is not easy for pests to develop drug resistance. Safe for humans and animals, can be mixed with most pesticides.

        Crops used
        Methylamino abamectin benzoate(SALT) is highly safe for all crops in protected areas or at 10 times the recommended dose, and is already used in many food and cash crops in Western countries. Consider that it is a low toxic pesticide that is environmentally friendly. Our country should first use it to control pests on cash crops such as tobacco, tea, cotton and all vegetable crops.

        paddy Cnaphalocrocis medinalis, Cnaphalocrocis medinalis, Leaf Roller medinalis, Rice planthopper, Soybean night moth, etc 8-10ml spraying


        Prevention and control of pests
        Methylamino Abamectin Benzoate (SALT) has incomparable activity to many pests with other pesticides, especially to lepidoptera, diptera, super efficient, Such as red leaf curling moth, tobacco aphidiphtera, cotton bollworm, tobacco moth, xylostella xylostella, beet moth, meadowworm, almond moth, cabbage silver moth, cabbage butterfly, cabbage heart moth, cabbage stripe moth, tomato moth, potato beetle, Mexican ladybird, etc. (beetles do not belong to the order Lepidoptera and Diptera).
        Methylamino Abamectin Benzoate (SALT) in use after a large number of clinical findings, the use of Methylamino Abamectin Benzoate (SALT) when adding pyrethroides can improve the quick-acting effect, in the growth period of the crop interval use effect is better.
        Methylamino Abamectin Benzoate (SALT) is easily degraded. Methylamino Abamectin Benzoate (SALT) is easily degraded by factors such as too high or too low acidity, light, etc. In the study of Methylamino Abamectin Benzoate (SALT) products, 0.35% anti-decomposition agent Wgwin ®D902 was added to the products containing Methylamino Abamectin Benzoate (SALT). It can effectively prevent the decomposition of Methylamino abamectin benzoate(SALT), and improve the activity of Methylamino abamectin benzoate(SALT) on pests of lepidoptera, mites, coleoptera and homoptera, and improve the efficacy.
