Abstract

The invention discloses application of pseudomonas chlororaphis to prevention and control of clubroot of cruciferae crops, and belongs to the field of microorganisms. The invention provides a biocontrol bacterium MCNB07405, which is preserved in the China General Microbiological Culture Collection Center (CGMCC), is classified and named as Pseudomonas chlororaphis, has a preservation number of CGMCC NO: 24326, is located at Institute of Microbiology, Chinese Academy of Sciences, No.3, No.1 Yard, Beichen West Road, Chaoyang District, Beijing, and has a preservation date of January 17, 2022. Experiments prove that the biocontrol bacterium has the activity of phosphoesterase and cellulase, the biocontrol bacterium has the potential of a biocontrol bacterium agent, the bacterium agent can prevent and treat the cabbage clubroot, the prevention and treatment effect is 56.8%, and it is indicated that the strain or the biocontrol bacterium agent has good market application prospects in the field of prevention and treatment of the clubroot of cruciferae crops.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to the application of a strain of Pseudomonas chloropinus to the prevention and control of clubroot of cruciferous crops. Background technique [0002] Brassicaceae is a large family with model plants (Arabidopsis thaliana) and has important economic value. Clubroot of cruciferous crops is a widespread plant disease caused by Plasmodiophora brassicae, which can lead to a severe decline in the yield of cruciferous crops, or even crop failure; and field soil contaminated by Plasmodiophora brassicae It will carry bacteria for a long time, seriously threatening the sustainable production and industrial development of cruciferous crops. In recent years, clubroot has become an important disease in Europe, North America, and Asia, and the harm of clubroot is becoming more and more serious in my country. Clubroot mainly damages the roots of host plants. The symptoms of the aboveground parts ...
