Abstract
The invention provides a tebuconazole-metalaxyl-M flowable concentrate for seed treatment as well as a preparation method and application of the tebuconazole-metalaxyl-M flowable concentrate, belonging to the technical field of pesticide bactericides. The tebuconazole-metalaxyl-M flowable concentrate for seed treatment comprises the following components in parts by weight: 0.8 to 1.2 parts of metalaxyl-M, 1.8 to 2.2 parts of tebuconazole, 4 to 6 parts of tristyrylphenol polyoxyethylene ether, 0.8 to 1.2 parts of docusate sodium, 0.18 to 0.22 part of xanthan gum, 0.8 to 1.2 parts of magnesiumaluminum silicate, 4 to 6 parts of propylene glycol, 4 to 6 parts of a warning-color BBC dye, 2.8 to 3.2 parts of an acrylic emulsion, 0.18 to 0.22 part of organic silicon and 76 to 77 parts of water. The tebuconazole-metalaxyl-M flowable concentrate for seed treatment provided by the invention is high in safety and good in stability.
Description
technical field [0001] The invention belongs to the technical field of pesticide fungicides, and in particular relates to a tebuconazole-metalaxyl seed treatment suspension and a preparation method and application thereof. Background technique [0002] The molecular formula of metalaxyl-M is C 15 h 20 o 4 N; It is light brown, viscous, transparent liquid. Melting point: -38.7°C (pure product), vapor pressure: 3.3×10-3Pa (25°C, pure product); fine metalaxyl is miscible with acetone, ethyl acetate, methanol, dichloromethane, toluene and n-octanol. Metalaxyl has an efficient control effect on diseases of vegetables, fruit trees, tobacco, oilseeds, cotton, grain and other crops caused by downy mildew, phytophthora, and pythium. [0003] Tebuconazole is an organic compound with the molecular formula C 16 h 22 ClN 3 O, is a high-efficiency, broad-spectrum, systemic triazole fungicidal pesticide, which has three functions of protection, treatment and eradication, with a wide...
