Plant bactericide containing milk protein composition

Abstract

The invention discloses a plant bactericide containing a milk protein composition, belonging to the field of plant disease control. The plant bactericide consists of the following main components in percentage by mass: 0.01-6% of a milk protein composition, 1-9% of iodide, 0.1-8% of rhodanate, 2-12% of a hydrogen peroxide source material, 6-25% of an auxiliary agent and the balance of water. According to the plant bactericide, a mixture of lactoperoxidase and lactalbumin, a mixture of hydrogen peroxide and sodium percarbonate as well as a special auxiliary agent are used as important bacteriocidal substances, so that the bactericidal performance and bactericidal effect of the plant bactericide are significantly improved, and the plant bactericide has the characteristics of strong bactericidal activity, good stability, long bactericidal lasting period and strong environmental adaptability, and can meet actual requirements in the field of plant disease control.

Description

technical field [0001] The invention belongs to the field of plant disease prevention and control, and in particular relates to a fungicide for plants containing a milk protein composition. Background technique [0002] Plant disease is a common and difficult problem encountered in the process of crop production, which can not only cause the reduction of crop yield, but also reduce the quality of agricultural products. A common control method against plant diseases is the application of chemical pesticides. [0003] Long-term use of traditional, highly toxic chemical pesticides, the effect of preventing and controlling plant diseases is becoming less and less obvious, while the resistance is becoming more and more obvious. Agricultural production relies solely on chemical pesticides for a long time, destroying the ecological structure of farmland, causing frequent outbreaks and large-scale occurrences of diseases and insect pests, and falling into a vicious circle in which ...

AI Technical Summary

Problems solved by technology

However, the plant growth space is relatively open and the environment changes greatly. The above technologies cannot meet the needs of plant sterilization.

Publication No. CN1350428 mentions that the lactoperoxidase system has an antimicrobial effect in cosmetics and health products. Since the types of microorganisms in cosmetics and health products differ greatly from plant pathogenic bacteria, they cannot be used in the field of plant sterilization

[0006] In general, the application of lactoperoxidase system in plant fungicides mainly faces the following problems: (1) The scope of action of plant fungicides is plant pathogenic microorganisms, and the role of the plant fungicide in the fields of medical and health, food, cosmetics, water treatment, etc. Compared with the target, the range is wider, and due to the long-term excessive use of chemical fungicides, the plant pathogenic microorganisms continue to be under high-intensity selection pressure, and the resistance increases rapidly; the required bactericidal ability is stronger; (2) the application site of plant fungicides Most of them are in the wild or in the greenhouse, and are greatly affected by environmental factors such as temperature, sunlight, humidity, wind, and rain; (3) The hydrogen peroxide in the lactoperoxidase system has poor stability and is easy to degrade
