Abstract

The invention discloses a strain Q2 which produces Penicillium purpureogenum and has been preserved in China General Microbiological Culture Collection Center (CGMCC for short) on 25th, October, 2016. The address is Institute of Microbiology, CAS, #3, Yard 1, West Beichen Road, Chaoyang District, Beijing. The preservation number of the strain is CGMCC NO.13165. According to the invention, the strain Q2 which produces Penicillium purpureogenum is separated from rhizosphere soil of cucumbers for the first time. The strain plays a relatively strong antagonistic role to a plant soil-borne disease bitter gourd wilt and provides a novel biocontrol bacterium for preventing and treating probable bitter gourd wilt and soil-borne diseases of other horticultural plants, so that the types of biocontrol agents are increased, and the phenomenon that the biocontrol agents are single in the market is overcome.

Description

technical field

[0001] The invention relates to an antagonistic fungus for preventing and treating balsam pear wilt and its application, in particular to a penicillium violet-producing fungus with remarkable control effect on balsam pear wilt and its application, which belongs to the field of biotechnology. Background technique

[0002] Bitter gourd wilt is a soil-borne disease caused by Fusarium oxysporumf.sp.momordicae infecting bitter gourd. It is widely distributed in various bitter gourd producing areas in the world. All can take place, can make a large amount of dead vines appear in the melon field when the disease is prevalent, reduce production more than 30%, have a strong impact on the yield and quality of bitter gourd.

[0003] At present, no effective disease-resistant varieties for this disease have been bred. In the past, chemical agents such as methyl bromide can be used to effectively control the occurrence of Fusarium wilt, but it is very polluting to the env...
