Triadimefon pesticide microemulsion and preparation method thereof

Abstract

The invention discloses triadimefon pesticide microemulsion and a preparation method thereof. The triadimefon pesticide microemulsion consists of the following components in percentage by weight: 5 to15 percent of triadimefon, 5 to 25 percent of organic solvent, 15 to 25 percent of primary surfactant, 3 to 10 percent of cosurfactant and the balance of water. The preparation method for the triadimefon pesticide microemulsion comprises the following steps: a, weighing the components according to the weight ratio, and mixing and stirring the primary surfactant and the cosurfactant until the mixture is transparent to form an emulsifier; b, mixing, stirring and dissolving the triadimefon and the organic solvent to give triadimefon solution; c, adding the emulsifier into the triadimefon solution and stirring the mixture; and d, adding the water into the mixture of the emulsifier and the triadimefon solution and stirring the mixture until homogeneous transparent liquid is prepared. The triadimefon pesticide microemulsion has good stability, light environmental pollution, high pesticide effect, simple production process, low production cost and high popularization value.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a pesticide microemulsion and a preparation method of the pesticide. Background technique [0002] At present, the pesticide formulations used in my country mainly include emulsifiable concentrate, wettable powder, granule, powder, water, suspension, microemulsion and so on. Triadimefon (triadimefon), also known as Fenxiu Ning, triazole dimethyl ketone, chlorothalone, Bailitong and so on. The pure product is colorless crystal with special smell, melting point 82.3℃, slightly soluble in water at 20℃, soluble in most organic solvents. The original powder is a white to light yellow solid with a melting point greater than 70°C and is relatively stable under acidic and alkaline conditions. It has the characteristics of high efficiency, broad spectrum, low residue, long residual period and strong systemic absorption. It is easily absorbed by plants and conducted in the body. I...

Problems solved by technology

At present, the main formulations of triadimefon preparations are emulsifiable concentrates and wettable powders. As the Chinese patent announcement number is CN1182783 to C, the date of announcement is January 5, 2005. Composition", comprising triazolone, metal inorganic acid salt having the following general formula: MXn.kH 2 O, M refers to metal ions in groups IIA, IIIA, IVA, IB, IIB, IVB-VIIB, and VIII, X refers to inorganic acid radicals, n is an integer of 1-4, k is 0-18, and is contained in the salt The number of crystal water has any ratio between them. The present invention has bactericidal and antibacterial spectrum, good drug effect and low toxicity, but the present invention is a kind of emulsifiable concentrate preparation; there is also wet powder, such as Chinese Patent Publication No. CN101195630A, which discloses On June 11, 2008, the title of the invention is "Functional Triadimefon Fungicide and Its Preparation Method and Application", which is to assemble triadimefon and metal salt into an ordered molecular structure in a suitable Placement, suction filtration, washing and vacuum volatilization, the above-mentioned triadimefon emulsifiable concentrates and medium-wet powders need to consume a large amount of toxic and flammable organic solvents in the production process, which is not conducive to the reduction of production and use costs, and has a negative impact on production, storage and transportation safety and the environment. protection from adverse effects
