After 6 years of research, Chinese scientists took the lead in the international development of a broad-spectrum, high-efficiency, safe, and effective control of fungal root rot and stalk rot of the biological pesticide - antibacterial agent nalormycin (M18). This is a major breakthrough in the field of biopesticides in China. After the promotion and application, it will generate several hundred million yuan of economic benefits each year. The fungal root rot and stalk rot of fruits and vegetables make China have an area of ​​more than 25 million mu per year, and economic losses amount to several billion yuan. For a long time, the main means of preventing and treating crop diseases is to spray chemical pesticides to make the pathogens produce drug resistance. The harmful components that remain in the edible parts of crops not only threaten the health of humans and animals, but also cause great damage to the ecological environment. Professor Xu Minquan, head of the School of Life Science and Technology at Shanghai Jiao Tong University, introduced: The antibacterial agent, Norromycin (M18), is a multi-function strain of bacteria screened from the rhizosphere soil of crops; it not only promotes plant growth, but also Spectral inhibition of various crop pathogenic fungi, and further developed into a new type of biological pesticides. The test results show that its control effect on a variety of withered diseases reaches about 75%, and can basically control the occurrence of withering diseases; it has a good therapeutic effect on the spoilage of melon and cantaloupe, and the treatment rate can also reach over 75%. . The pesticide also has the characteristics of high efficiency, low toxicity, low residue, and good compatibility with the environment. The research results are the first in China, reaching the international advanced level, and have applied for national patents.
