Microorganism plant vaccine capable of controlling tomato bacterial wilt disease

Abstract

The invention relates to microorganism plant vaccine capable of controlling continuous tomato bacterial wilt disease, and belongs to the agricultural intensive production technology. According to the microorganism plant vaccine capable of controlling the tomato bacterial wilt disease, a ralstonia solanacearum sibling bacterium pearson ralstonia eutropha (Ralstoniapickettii) NJQL-A6 is isolated from the rhizosphere of a healthy tomato, and the ralstonia eutropha has a weaking inhibited impact on a bacterial wilt pathogenic bacteria ralstonia eutropha (Ralstonia solanacearum) panel. However, the ralstonia eutropha possesses powerful colonization capability on the tomato rhizosphere and inside a plant, and can inhibit the infection of the ralstonia eutropha to a tomato plant. Experiments show that after the vaccine is irrigated to be applied to soil, the vaccine can breed rapidly so that an advantage group is formed in the soil, and the biocontrol efficiency can be reached up to more than 70% in the soil where the tomato bacterial wilt disease is severe. By inoculating the biocontrol bateria on the tomato plant with the root being infected by the bacterial wilt on the overground part, the further development of the disease can be effectively controlled.

Description

1. Technical field [0001] The invention discloses a microbial plant vaccine capable of preventing and controlling bacterial wilt disease of continuous cropping tomato, belonging to the agricultural intensive production technology, and is specially used for overcoming and eliminating the problem of bacterial wilt disease of continuous cropping tomato. 2. Background technology [0002] Tomato bacterial wilt is a bacterial vascular soil-borne disease caused by Ralstonia solanacearum. This disease was first discovered and reported by Simth scholars in the United States in 1906. So far, except Antarctica, other countries and regions have the existence of R. solanacearum. Ralstonia were divided into five physiological races and six biochemical races. All races had certain pathogenicity to tomato, and physiological race 1 had the strongest pathogenicity to tomato. In my country, tomato bacterial wilt mainly occurs in the warm and humid south. With the warming of the climate and t...

AI Technical Summary

Problems solved by technology

At present, many vegetable bases in the south are no longer suitable for growing tomatoes, which has a great impact on the development of my country's tomato market.

At present, there is no effective means to control tomato bacterial wilt, and the use of rhizosphere microorganisms to control diseases is one of the important measures for comprehensive control of soil-borne diseases
