Effective control of bacterial wilt by "plant vaccine" instead of pesticide

The reporter learned from the Annual Academic Summit of Chinese society of Microbiology held here that a research team of Fujian Academy of Agricultural Sciences, after years of efforts, has developed a new type of "plant vaccine" by using non pathogenic bacteria of plant pathogens to replace chemical pesticides, successfully prevent and control the pathogens during the growth of related plants, and become the key to the development of modern agriculture and food safety Powerful means According to Liu Bo, head of the research team and President of Fujian Academy of Agricultural Sciences, the "plant vaccine" is named "elutelun", which is mainly used to prevent and control bacterial wilt of eggplant, tomato, pepper, tobacco and other plants Bacterial wilt is a devastating soil borne disease caused by Ralstonia solanacearum, which is very serious in Sichuan, Zhejiang, Fujian, Jiangxi, Guangdong, Guangxi and other provinces Liu Bo said that Ralstonia solanacearum has a long survival time and fast spread, and no effective chemical control method has yet been found The researchers use the principle of microbial immune disease resistance to activate the immune system of plants, improve the immune ability of plants, so as to enhance the disease resistance of plants Since 2008, researchers have developed the preparation method and production process of "elutelun", and used its 300 times diluent to root tomato seedlings in 4 mu land, the effect of virus control reached 83% In March 2010, "elutelun" carried out the expansion test in the factory seedling base of Xiamen Ruyi group, a leading national agricultural industrialization enterprise Without the application of chemical agents, it effectively solved the occurrence of rotten seedlings in the long-distance transportation of vegetable seedlings in the enterprise, and the effect of controlling plant viruses was obvious "At present, the" elutelun "has entered the field test stage The latest test results show that it can effectively control crop diseases at seedling stage, while significantly reducing the cost of control." Liu Bo told reporters, "it will be a new trend and an important means to reduce the pollution of chemical pesticides to the environment and agricultural products from the source by immunizing plants before they are harmed by pathogens so that they can acquire immune resistance."
