Tebuconazole water dispersible granule and preparation method thereof

Abstract

The invention discloses a tebuconazole water dispersible granule and a preparation method thereof. The weight percentages of components in the formula of the tebuconazole water dispersible granule areThe invention discloses a tebuconazole water dispersible granule and a preparation method thereof. The weight percentages of components in the formula of the tebuconazole water dispersible granule areas follows: 45 percent to 80 percent of tebuconazole, 1 percent to 30 percent of disintegrating agent, 3 percent to 15 percent of dispersing agent, 3 percent to 5 percent of wetting agent, 0.1 percen as follows: 45 percent to 80 percent of tebuconazole, 1 percent to 30 percent of disintegrating agent, 3 percent to 15 percent of dispersing agent, 3 percent to 5 percent of wetting agent, 0.1 percent to 2 percent of binder, 0.1 percent to 0.5 percent of stabilizing agent and the balance of carrier. The preparation method comprises the steps: the components in the formula of the tebuconazole watet to 2 percent of binder, 0.1 percent to 0.5 percent of stabilizing agent and the balance of carrier. The preparation method comprises the steps: the components in the formula of the tebuconazole water dispersible granule are evenly mixed and pulverized into precursor powder by a super-micro air flow pulverizer; a certain proportion of deionized water is added into and evenly mixed with the precurr dispersible granule are evenly mixed and pulverized into precursor powder by a super-micro air flow pulverizer; a certain proportion of deionized water is added into and evenly mixed with the precursor powder; and then, the obtained mixture is granulized, dried and screened in sequence to obtain the tebuconazole water dispersible granule. The tebuconazole water dispersible granule overcomes defesor powder; and then, the obtained mixture is granulized, dried and screened in sequence to obtain the tebuconazole water dispersible granule. The tebuconazole water dispersible granule overcomes defects of wettable powder and reduces the use costs of farmers and environmental pollution during the processing and using processes thereof. As auxiliary agents with different components are added, thects of wettable powder and reduces the use costs of farmers and environmental pollution during the processing and using processes thereof. As auxiliary agents with different components are added, thetebuconazole water dispersible granule has the advantages of high active-compound content, high disintegration speed, good dispersibility, stable thermal storage, high sterilization efficiency, high stebuconazole water dispersible granule has the advantages of high active-compound content, high disintegration speed, good dispersibility, stable thermal storage, high sterilization efficiency, high safety in use, and the like.afety in use, and the like.

Description

technical field [0001] The invention relates to a pesticide fungicide, in particular to a tebuconazole water-dispersible granule and a preparation method thereof. The product is mainly used for preventing and controlling plant fungal diseases. Background technique [0002] Traditional types of pesticides such as emulsifiable concentrates, powders and wettable powders account for about 80% of the total preparations in my country. With the development of processed dosage forms, the shortcomings of traditional dosage forms have become more prominent. The emulsifiable concentrate contains a large amount of organic solvents such as xylene and toluene, which not only causes serious pollution to the environment, but also wastes petrochemical resources. Due to its very fine particle size, wettable powder often produces flying dust during production and use, which not only endangers people's health, but also causes environmental pollution. A small amount of flying dust can easily cau...

Problems solved by technology

[0004] At present, the main dosage forms of tebuconazole fungicide products used in the pesticide market are emulsifiable concentrates and suspension concentrates, but the high-efficiency, low-toxicity, and environmentally friendly tebuconazole water-dispersible granules have not been effectively used
