Details:

 Wuhan Zeshancheng Biomedical Technology Co., Ltd. is a technology enterprise integrating R&D and sales. Since its establishment, the company has adhered to the business philosophy of "technology first, customer first", and always provided customers with good products and technical support as well as sound after-sales service. With a professional sales team, the business has continued to develop and steadily increased, and the products are exported to all parts of the world and major cities in China.

    Our company is mainly engaged in the R&D of biological medicine technology, the R&D and sales of biological products and food additives, and the import and export business of various commodities and technologies (except those restricted or prohibited by the state) (for projects that need to be approved according to law, business activities can only be carried out after being approved by relevant departments)

    Main products: cosmetic raw materials (whitening series, preservatives, sunscreen agents, rheology modifiers, surfactants, etc.), chemical raw materials (catalysts, additives, raw materials, etc.).

The application is to prevent and control cotton bollworm, tobacco worm, vegetable plutella xylostella, beet moth, thrips and other pests on cotton. Chemical properties light gray solid crystal, with a slight stale earthy odor. The vapor pressure is about 1.3×10-10Pa. In aqueous solution with pH 7.74, the p-metal and metal ions are relatively stable for 28 days. The half-life of photodegradation in soil is 9 ~ 10 days. The half-life of water photolysis is <1d. In the range of pH 5 ~ 7, it is relatively stable in aqueous solution. At pH 9, the half-life is >200d. Multicidin is A mixture containing more than ten components, the main components are A and D. The melting point was 84 ~ 99.5℃, the vapor pressure was 3.2×10-10Pa, and the solubility in water was 290mg/L(pH=5.0), 235mg/L (pH= 7.0), 16mg/L(pH=9.0), respectively. The distribution coefficients were 2.8, 4.0 and 5.2 at the corresponding pH values. The melting point of polysterilin D is 161.5 ~ 170℃, the vapor pressure is 2.1×10-1Chemicalbook0Pa, and the solubility in water is 29mg/L(pH=5.0), 0.332mg/L(pH=7.0), 0.053mg/L(pH=90.0), respectively. The distribution coefficients were 3.2, 4.5 and 5.2 at the corresponding pH values. It is a new type of biocide with its unique chemical structure and the characteristics of safety and quick effect. It has won the "President's Green Chemical Challenge Award" in the United States for its low toxicity, low residue and safety. It works by stimulating the insect's nervous system, leading to non-functional muscle contractions and failure, accompanied by tremors and paralysis. The results were consistent with the activation of nicotinic acid acetylcholine receptor, and also acted on γ-aminobutyric acid receptor, further promoting its insecticidal activity. This mode of action is favored. It can effectively control the pests of Lepidoptera (such as Plutella xylostella, beet night butterfly, etc.), diptera and Tasseloptera, and also can control some insect species of Coleoptera and orthoptera that eat a lot of leaves. It is not effective against stinging insects and mites.
