Bentoketone
Chinese common name: benzophenone
Common name in English: Metrafenone
Compound name: 3'-bromo-2,3,4,6'-tetramethoxy-2',6-dimethylbenzophenone
CAS accession number: 220899-03-6
Molecular formula: C19H21BrO5
Relative molecular weight: 409.27
Physical and chemical properties: The original drug is white to off-white crystals, with a slight musty smell. Melting Point: 99.2~100.8 °C, Vapor Pressure: 1.53×10-4 Pa(20 °C); The solubility in water (mg/L, 20 °C) was: 0.552 (pH 5), 0.457 (pH 7), 0.457 (pH 9). Solubility in organic solvents (g/L, 20 °C): acetone 403, acetonitrile 165, dichloromethane 1950.
Mechanism of action and use: It mainly inhibits the spore germination of powdery mildew and controls the spread of the disease by interfering with the development and formation of attachment cells during spore germination of pathogenic bacteria. It can effectively control the harm of powdery mildew and has obvious preventive and therapeutic effects.
Benylone has several times higher bactericidal activity than pyrimeclic amine, and has no cross-resistance to those inhibitors with dimethylation and aniline pyrimidine fungicides, and can be used for the prevention and control of powdery mildew in cereals, grapes, cucumbers, beans, strawberries and other crops.

Lime nitrogen
Lime nitrogen is a mixture of calcium cyanamide, calcium oxide and other insoluble impurities, which is gray-black in color and has a special odor. It is an alkaline fertilizer and one of the main raw materials of high-efficiency and low-toxicity carbendazim pesticide, which can be used as herbicide, fungicide, insecticide, etc.; additionally, it can be applied to manufacture cyanide melt and cyanide to make dicyandiamide, melamine and thiourea. Lime nitrogen is an important organic chemical material, which can be utilized as a metal heat treatment agent as well as for the elimination of schistosomes.
Lime nitrogen
Lime nitrogen, also known as calcium cyanamide and black fertilizer, is a dark-gray oily particles with the chemical formula CaCN2, which contains about 20% nitrogen. Lime nitrogen gets its name from the lime component it contains. It is a soil purifier that can be utilized both medicine and fertilizer, and has the dual role of soil disinfection and fertilization.
Dicyandiamide
Dicyandiamide, abbreviated as DICY or DCD, is an organic compound with the chemical formula C2H4N4. Dicyandiamide is a dimer of cyanamide andalso a cyano derivative of guanidine. Dicyandiamide is a white crystalline powder that is soluble in water, alcohol, ethylene glycol and dimethylformamide, and practically insoluble in ether and benzene. Dicyandiamide is non-flammable and is stable when dry.
