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

[0019] The present invention will be further described below in conjunction with specific examples, so as to better understand the present invention.

[0020] The invention provides an actinomycete, which is Streptoverticillium lilacinus XJQ-SCA3-4 (Streptoverticillium lilacinus XJQ-SCA3-4), the preservation number is CCTCC NO: M 2017489, and the preservation date is September 11, 2017 , the depository unit is the China Center for Type Culture Collection, and the depository address is Wuhan University, Wuhan, China. The S. syringae XJQ-SCA3-4 of the present invention is obtained by separating and screening from cactus rhizosphere soil collected from dry-hot valleys in Huili County, Sichuan Province.

Abstract

The invention provides actinomycete, particularly discloses syzygium aromaticum streptoverticillium SCA3-4, with the preservation number CCTCC being NO: M 2017489. The syzygium aromaticum streptoverticillium SCA3-4 has antagonistic effect on banana fusarium oxysporum No.4, banana fusarium oxysporum No.1, banana long cercosporidium sojkinum, gloeosporium musarum, colletotrichum gloeosporioides, colletotrichum capsici, banana tree pathogens causing canker, alternaria musae, banana large gray leaf spot pathogen, mango alternaria leaf spot germ and pestalogiopsis, has wide development space for the prevention and treatment of banana wilt, babana long spot, banana anthracnose, strawberry anthracnose, pepper anthracnose, banana tree canker, banana alternariamusae, banana large gray leaf spot, mango alternaria leaf spot and pestalogiopsis, and has a good development and application prospect.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to Streptothrix syringae 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...
