Problems solved by technology

However, the main problems of pesticides are: 1. There are toxic residues, which are harmful to the human body and the environment, so the frequency of application is limited
2. Most diseases are resistant to pesticides
[0007] But to make chlorine dioxide can be used in the field environment, several problems need to be solved: first, because the stability of the pure form of chlorine dioxide gas or chlorine dioxide aqueous solution is very poor, generally it can only be used immediately after mixing, and the field environment Interference will make chlorine dioxide in its pure form ineffective very quickly, making it almost ineffective to sterilize
[0008] Secondly, the most likely form of chlorine dioxide in the wild environment is aqueous solution, and there are often many crops that are resistant to aqueous solution, such as rice, cabbage, etc., which will greatly reduce the sterilization efficiency

Abstract

The invention belongs to the fields of disinfection, chemistry and chemical engineering and agricultural application, and particularly relates to a method for improving chlorine dioxide aqueous solution stability and efficacy thereof in a field environment. The invention aims to provide an auxiliary agent and a preparation method capable of reinforcing field stability of chlorine dioxide aqueous solution so as to improve efficacy thereof, and provide a safe and efficient disinfectant for preventing and treating agriculture and forestry crop diseases. The disinfectant is formed by three substances: the chlorine dioxide aqueous solution and auxiliary agent substances A and B, and a preparation method for compounding the three substances is provided. A weight ratio of the chlorine dioxide aqueous solution and the substance A is 100:0.01-0.1:100, and a weight ratio of the chlorine dioxide aqueous solution and the substance B is 100:0.01-0.1:100. It is indicated from an experiment that thechlorine dioxide aqueous solution has the good effect in the field environment.

Description

technical field [0001] The invention belongs to the fields of disinfection, chemical engineering and agricultural application, and in particular relates to a method for improving the stability and efficacy of chlorine dioxide aqueous solution in the field environment, which can be widely used for preventing and controlling agricultural and forestry crop diseases. Background technique [0002] There are two environments for the prevention and control of agricultural and forestry crop diseases, indoor and outdoor. Indoor environmental factors are relatively simple (such as seed soaking and disinfection, greenhouse disinfection, etc.), while the wild environment is much more complicated, but crop diseases often occur in large numbers in the wild environment. , The interference factors of the agent are: temperature and humidity, light, wind, rain, the impedance of the crop itself to the agent, etc. Therefore, compared with the indoor environment, the sterilization efficiency drop...
