Problems solved by technology

Chemical control is currently the most effective measure to prevent fungal diseases. The annual use of chemical pesticides in my country is 500,000-600,000 tons, which has brought serious pollution and harm to the environment and ecology. In some countries and regions, chemical fungicides have been restricted. use

Abstract

The invention relates to the technical field of Bacillus, particularly a salt-tolerant Bacillus strain. The Bacillus is Bacillus atrophaeus. The Bacillus atrophaeus strain is selected from a strain named Ba10, the Ba10 is collected by China General Microbiological Culture Collection Center, and the collection number is CGMCC No.12053; and / or the Bacillus atrophaeus strain is selected from a strain named Ba27, the Ba27 is collected by China General Microbiological Culture Collection Center, and the collection number is CGMCC No.12054. The Bacillus atrophaeus strain can inhibit multiple pathogens from growth, and has tolerance to high-concentration salts.

Description

technical field [0001] The invention relates to the technical field of bacillus, in particular to a disease-resistant and salt-tolerant bacillus. Background technique [0002] Fungal diseases seriously endanger global food security, and 70%-80% of plant diseases are caused by the infection of pathogenic fungi. rice blast Pyricularia oryae Cav. Outbreaks in 85 countries around the world have caused 10%-35% food loss, and even some fungal diseases have caused serious death and extinction of animals and plants. Sclerotinia can infect more than 400 species of plants, including Brassicaceae, Leguminosae, Solanaceae, Compositae, and Umbelliferae, etc. It is the first of the three major diseases of rapeseed, and the yield loss can reach 80% when it is serious. Chemical control is currently the most effective measure to prevent fungal diseases. The annual use of chemical pesticides in my country is 500,000-600,000 tons, which has brought serious pollution and harm to the environme...
