Problems solved by technology

Some cultivation management measures can only play a partial control role
And the long-term use of some chemical fungicides and modifiers can easily lead to the problem of drug resistance of pathogenic bacteria, and damage the ecological environment of the soil, which is not safe for humans

Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific examples, so as to better understand the present invention.

[0016] The invention provides an actinomycete, which is Streptomycessamsunensis XJC-2-6 (Streptomycessamsunensis XJC-2-6), the preservation number is CCTCC NO: M 2017620, and the preservation date is October 23, 2017. The depository unit is the China Center for Type Culture Collection, which is located at Wuhan University in Wuhan, China. The Streptomyces samsonii XJC-2-6 of the present invention is isolated and screened from coral samples collected from the South China Sea.

The streptomyces samsunensis XJC-2-6 provided by the invention has anantagonism on fusarium oxysporum f.sp cubense No. 4, curvularia fallax, curvularia lunata, btoryosphaeria dothidea, colletotrichum acutatum, colletotrichum gloeosporioides, colletotrichum fragariae,botrytis cinerea, fusarium oxysporum (schl.) f.sp cucumerinum owen, colletotrichum acutatum, pyricularia oryae cav, fusahum graminearum sehw, botryosphaeria dothidea and the like, has wide developmentspace on prevention and treatment of Panama disease of banana, microscler streak disease of banana, large grey speck disease of banana, tree canker of banana, anthracnose of pepper, anthracnose caused by colletotrichum gloeosporioides, anthracnose of strawberry, disease caused by botrytis cinerea, fusarium wilt of cucumber, anthracnose of mango, rice blast, wheat scab, ring rot of apple and the like, and has very good development and application prospects.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to Streptomyces samsonii and its application. Background technique [0002] Banana Fusarium wilt, also known as Panama disease and banana yellow leaf disease, is a vascular wilting disease caused by Fusarium oxysporum f.sp.cubense. The pathogen invades from the root wound of the host, and spreads to the upper leaves through the corm and pseudostem through the vascular bundle. The pathogen blocks the xylem vessel, hinders the water transportation of the plant, and causes the plant to wither and die. This devastating soil-borne disease, once a field develops, the germs spread quickly and are difficult to cure, so it is called "banana cancer". Therefore, it is imminent to control banana wilt. [0003] At present, there is no effective control method for the disease, and there are no ideal chemical agents and high-quality disease-resistant varieties. Some cultivation managem...
