(TM, Trade-Mark) "Technical production of thionidazole" was included in China's Export-Restricted Export Technology Catalog No. 982903X, and it belongs to China's independent intellectual property chemical pesticide production technology. 2. The bactericidal mechanism of thiobite, the ultra-fine product of Dragon Brand: Long brand superfine thiophene thiazole is a new type of heterocyclic bactericide, has a strong internal permeability, at the same time has a therapeutic and preventive role, the treatment effect is more significant. The thiazole group is a highly effective therapeutic agent in plants, and the agent is severely damaged in the plant's holey catheter. The cell wall becomes thin and then collapses, resulting in the death of the bacteria. The mechanism of action of thiophenazole, a superfine product of Long Brand, is an esterase system that interferes with the amino acid metabolism of pathogens through thiadiazole, destroys the biosynthesis of proteins, inhibits the growth of mycelium and causes cell pellets, and causes the loss of reproduction and infestation of pathogenic bacteria. Ability to achieve the purpose of killing pathogens and preventing diseases. Long brand superfine quality thiazolyl is mainly used for the prevention and control of plant bacterial diseases, and it is ideal for field control of crop bacterial diseases. 3. Introduction of Dragon Brand Thiophenazole (20% WP): Ministry of Agriculture Official Registration Number of pesticides: PD86153-8 Pesticide production approval certificate: HNP33036-D0173 Product quality standard number: Zhejiang B/HG182-87 English common name: bismerthiazol Chemical name: N.N'-methylene-bis(2-amino-5-thio-1,3,4-thiadiazole) CAS: 79319-85-0 Molecular Formula: C5H6N6S4 Molecular weight: 278.38 Chinese name: N,N-methylene-bis(2-amino-5-mercapto-1,3,4-thiadiazole); English name: N,N-Methylene bis(2-amino-5-mercapto-1,3,4-thiadiazole) Chinese common name: thiazolyl, methimazole; Product Name: Ye Qingshuang, Chuanhua-018, Ye Kuning. 4. Longitudinal quality thiazole in nature Description: Dragon brand quality thiazole, white rectangular column crystal or light yellow loose powder, melting point 190 °C 1 °C, decomposition temperature 200 °C. Soluble in dimethylformamide, dimethyl sulfoxide, pyridine, ethanol, methanol, etc., insoluble in water. More stable to alkali. Dragon brand quality thiothiazide toxicity LD50 (mg/kg): rat acute oral (the original drug) LD503160 ~ 8250mg/kg; mouse 3480 ~ 6250 mg/kg. The rats were fed with 0.25 mg/kg for one year without bad shadows. Teratogenic carcinogenic mutagenicity tests are all within the safe range. Use of human and animal safety. No allergic and dermatitis symptoms were observed during the production process. 5, Dragon brand quality thiopicazole Note: Dragon brand quality thiazole azole is a low-toxic bactericide, chemically stable. In use or after use, if the body is unwell, it should immediately go to the hospital for treatment and symptomatic treatment according to the symptoms. 6, Dragon brand quality thiazole technology preparation: It is prepared from hydrazine hydrate, sodium thiocyanate, formaldehyde and carbon disulfide as raw materials. Hydrazine hydrate reacts with sulfuric acid to form barium sulfate, which is then reacted with sodium thiocyanate under the action of a catalyst to form dithiourea and sodium sulfate. Under the action of the catalyst, carbon disulfide is used for the ring closure reaction to produce 2-amino-5. Thio-1,3,4-thiadiazole; must finally be condensed with formaldehyde to produce mettilazole (thiazole) (this is the most important part to determine true and false Yeqing double). 7, Dragon brand thiazolyl use: A systemic low toxicity germicide. It is mainly used to control bacterial diseases in crops. Preparations are 20% wettable powders. It is an excellent agent for the control of rice bacterial blight, rice bacterial streak disease, citrus canker disease, cabbage soft rot. It has good internal absorption and conduction, and it has preventive and therapeutic effects. It has a long effective period, stable efficacy, and no harm to crops. The dragon brand thiazolyl tetrazolium mainly controls bacterial blight such as bacterial leaf blight, rice bacterial streak disease, cabbage soft rot disease, tomato bacterial wilt disease and citrus canker disease. 8, Dragon brand quality thiazolazole processing formulations are: WP and suspension agents. 9, Dragon brand boutique thiophene packaging and storage: Zhejiang Longwan Chemical Co., Ltd. 20% WP is packed in plastic bags lined with kraft paper bags, 25, 100, 150, 200, 250 grams per bag, plus cartons, each box (20, 25, 50 bags or 100, 200 bags) ), Each item has a net weight of 5 or 7.5 kg. The large package is 50 kg brown paper bag. 10, Dragon brand quality thiazolyl use technology complete program: 1. Control bacterial blight of rice and bacterial bacterial streak of rice: In the early stage of rice onset and at the beginning of heading, or in the paddy field at the 4 to 5 leaf stage, use 20% WP wettable powder of 125 grams per mu. For water 75 ~ 100kg, foliar spray, spraying 2 times (interval 7 ~ 10 days) is appropriate. 2. Control of orange canker disease: The Mu brand dragon fine-quality thiazolyl 20% WP 100 to 150 grams, and the water 600 was sprayed with liquid.
