Preparation method of sterilization medicament and sterilization medicament

Abstract

The invention provides a preparation method of a sterilization medicament. The preparation method of the sterilization medicament is characterized in that liquorice, radix scutellariae, dried alum and honeysuckle are smashed, the mixture is screened with a sieve with the mesh numbers being 20-40, ethyl alcohol with the concentrate being 30%-70% is added to the smashed mixture to completely submerge the smashed mixture, the amount of the ethyl alcohol is 6-7 times that of the smashed mixture, and dipping is conducted for 24-72 h; then, the mixture is percolated in a percolator, large-sized particles are filtered off, obtained filter liquor is heated, residual ethyl alcohol is volatilized, and the obtained liquor is concentrated until the solid-to-liquid ratio is 1:1; centrifugal separation or resin adsorption is conducted, fine particles and other impurities are filtered off, and obtained filter liquor stands for use; iodine is mixed with an emulsifying agent, and a cream object is obtained through emulsification and complexation and stands for use; the filter liquor and the cream object are mixed and evenly stirred, water is added to the mixture for attenuation, and after even stirring, medical phosphoric acid is added to adjust the ph to be 1.3-2.8; and finally, the product is obtained after filling and sealing.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a method for preparing a bactericidal agent and a product prepared by the method. Background technique [0002] Chemical agents play an important role in the control of crop diseases and insect pests. However, due to the long-term use of chemical agents, the frequency of resistance to diseases and insect pests in most areas exceeds 50%, and the resistance level is as high as more than 10,000 times. The single use of chemical agents has completely lost the control effect. Moreover, with the continuous enhancement of resistant strains, the frequency of pesticide application has increased year by year, and the amount of pesticide application has also doubled, which has brought great pressure to the control and the surrounding environment. Its disadvantages are also becoming more and more prominent, such as drug residues, environmental pollution and harmful organisms rampant...

[0002] Chemical agents play an important role in the control of crop diseases and insect pests. However, due to the long-term use of chemical agents, the frequency of resistance to diseases and insect pests in most areas exceeds 50%, and the resistance level is as high as more than 10,000 times. The single use of chemical agents has completely lost the control effect

Moreover, as the resistant strains continue to increase, the number of spraying increases year by year, and the amount of spraying also doubles, which brings great pressure to the control and the surrounding environment.

Its disadvantages are also becoming more and more prominent, such as drug residues, environmental pollution and harmful organisms are rampant again, etc.
