This invention provides Bacillus subtilis ( Bacillus subtle The application of strain A45 in the control of plant diseases, its application in the preparation of microbial agents for the control of plant diseases, and the prepared microbial agents. Bacillus subtilis A45 is deposited at the China General Microbiological Culture Collection Center (CGMCC), with accession number CGMCC No. 33289. The liquid microbial agent containing Bacillus subtilis A45 provided by this invention effectively inhibits the cucumber target spot pathogen, *Clostridium multiflorum* (…). Corynespora cassicola The growth mechanism of this strain lies in its encoding a gene cluster for the synthesis of phytosalicylic acid, purchemin, subtilosin A, and surfactant. Among these, the surfactant synthesis gene cluster is unique to this strain, exhibiting a maximum sequence similarity of 82%. Experiments show that the liquid inoculant containing Bacillus subtilis A45 provided by this invention can effectively inhibit the growth of *Clostridium multiflorum*, the pathogen causing target spot disease in cucumbers. Corynespora cashew nut The growth of ) can be controlled by field application with a prevention and control effect of up to 80%.

The invention discloses application of pyrimethanil in prevention and treatment of pathogenic fungi of crops. The pyrimethanil has excellent bacteriostatic activity on pathogenic fungi of crops, and can be used for preventing and treating diseases caused by the pathogenic fungi of important economic crops such as vegetables, tea trees, rice, fruit trees and the like. According to the application disclosed by the invention, the pyrimethanil is found to have a remarkable antibacterial effect on pathogenic fungi such as trichospora fistula, corynespora cassiicola and the like; the bactericidal composition can be compounded with berberine according to a ratio of 1: 2 or 2: 1, or compounded with luteochlorin according to a ratio of 2: 1, and has a synergistic effect in prevention and treatment of corynespora cassiicola.
