Abstract

The invention is applicable to the technical field of bactericides, and provides a preparation method of a bactericide for preventing and treating crop germs. The bactericide is prepared from the following components in parts by weight: 40-60 parts of plant sterilization liquid, 20-40 parts of penetrating fluid and 20-40 parts of synergist, and the main raw materials of the plant sterilization liquid are celastrus orbiculatus, Chinese juniper, cortex dictamni and herba houttuyniae; the main raw material components of the synergist are abscisic acid and chitin. The preparation method of the bactericide specifically comprises the following steps: preparing the plant sterilization liquid, preparing the synergist, and then mixing to obtain the bactericide. Through combined use of the plant sterilization liquid and the synergist, the bactericide has a good killing effect on pathogenic bacteria, can improve the resistance of crops to pathogenic bacteria, and can avoid secondary infection of pathogenic bacteria.

Description

technical field [0001] The invention belongs to the technical field of fungicides, and in particular relates to a preparation method of a fungicide for preventing and controlling crop pathogens. Background technique [0002] Bactericides, also known as biocides, bactericides and algicides, microbicides, etc., usually refer to chemical agents that can effectively control or kill microorganisms such as bacteria, fungi, and algae. Internationally, it is usually used as a general term for agents to prevent and control various pathogenic microorganisms. Primary fungicides are defined as chemicals that kill fungi or inhibit their growth. With the development of fungicides, the scientific definition includes pesticides that can directly kill or inhibit the growth and development of plant pathogens, or some pesticides that have no direct biological activity on pathogenic bacteria, but by changing the pathogenic process of pathogenic bacteria or by inducing plant resistance Sex, so...
