Abstract

The invention relates to a Bacillus cereus strain for preventing and treating melon root rot, and a culture method and application thereof. The Bacillus cereus NY3 strain for preventing and treating melon root rot was collected by China General Microbiological Culture Collection Center on January 7th, 2016; the address is Institute of Microbiology, Chinese Academy of Sciences, No.3 Yard 1, Beichenxi Road, Chaoyang District, Beijing; and the strain collection number is CGMCC No.11962. The invention also discloses a method for preparing a liquid microbial inoculant by using the strain and application of the strain in preventing and treating melon root rot. The invention detects for the first time that the Bacillus cereus NY3 can effectively inhibit growth of Fusarium solanae under the condition of low concentration, has wide bactericidal application range, and has preventing and treating effects on cucumber root rot, tomato root rot and the like.

Description

technical field

[0001] The invention relates to a bacillus cereus for preventing and treating melon root rot, a cultivation method and application thereof, and belongs to the technical field of biological control of plant diseases. Background technique

[0002] Root rot is a common disease of melons. It is more common in the division of seedlings or before the slow seedlings after planting, and the damage is serious. The pathogen is mainly Fusarium solani of melons. The pathogen survives the winter as chlamydospores, mycelia or sclerotia in the soil and on the diseased residues. The chlamydospores can survive in the soil for 5-10 years. Chlamydospores are the main source of infection causing the disease. The bacteria invade from the root wound. After the onset, conidia are produced in the diseased part, spread by rain or watering, and repeat infection. Once it occurs, it is difficult to cure. For a long time, the field control of this disease has mainly relied on chemical f...
