Hot fogging concentrate containing tebuconazole and triazophos and preparation method thereof

Abstract

The invention discloses a hot fogging concentrate containing tebuconazole and triazophos, and a preparation method and application thereof. The hot fogging concentrate containing tebuconazole and triazophos comprises the following raw materials in percentage by mass: 3-20% of tebuconazole, 15-35% of triazophos, 5-30% of solvent, 1-15% of surfactant, 0.1-5% of thickener, 1-8% of hot fog density regulator, 1-8% of antifreezing agent, 0.1-1% of defoaming agent and the balance of water. The preparation method comprises the following steps: dissolving the effective components tebuconazole and triazophos in the solvent to prepare an oil phase, dissolving other auxiliary materials in water to prepare a water phase, and finally, evenly mixing the oil phase and the water phase to obtain the hot fogging concentrate containing tebuconazole and triazophos. The hot fogging concentrate disclosed by the invention is a broad-spectrum disinsection composition, and is used for preventing and treating plant diseases and pests when being matched with a hot fog machine. The invention has the advantages of high application efficiency, favorable effect and low environmental pollution, is applicable to low-straw plants, such as cotton, sunflower, corn, sorghum, wheat and the like, and can greatly alleviate the contradiction between the lack of labor force and the difficulty in preventing and controlling the crop diseases and pests in the medium and later periods in the countryside at present.

Description

technical field [0001] The invention relates to the field of plant disease and insect pest control, in particular to a thermal mist containing tebuconazole and triazophos, a preparation method and application thereof. Background technique [0002] At present, most of the tebuconazole produced at home and abroad are water-based emulsions and suspensions, and most of the triazophos products are emulsifiable concentrates, especially the latter is mainly prepared from toluene, xylene, solvent oil, etc. with a lower boiling point. In the process of spraying, a large amount of fresh water needs to be mixed to form an emulsion before spraying. The loss of active ingredients is serious. At the same time, it is highly toxic to the environment and operators. [0003] Thermal mist has developed slowly at home and abroad, and is mostly used for sanitation or the prevention and control of plant diseases and insect pests in forests and greenhouses. It cannot be used in relatively open spa...

Problems solved by technology

[0002] At present, most of the tebuconazole produced at home and abroad are water-based emulsions and suspensions, and most of the triazophos products are emulsifiable concentrates, especially the latter is mainly prepared from toluene, xylene, solvent oil, etc. with a lower boiling point. During the spraying process, a large amount of fresh water needs to be mixed to form an emulsion before spraying. The active ingredients are seriously lost. At the same time, it is highly toxic to the environment and operators, with high labor intensity and low work efficiency, and it is difficult to apply to mid-late stage diseases of sorghum crops such as corn and sorghum

[0003] Thermal mist has developed slowly at home and abroad, and is mostly used for sanitation or the prevention and control of plant diseases and insect pests in forests and greenhouses. It cannot be used in relatively open spaces or low-stalk plants. It is easy to diffuse into the atmosphere with the updraft, which not only reduces the efficacy of the medicine, but also easily causes environmental pollution
