Embodiment Construction

[0052] The present invention will be further described below in conjunction with specific examples, so as to better understand the present invention.

[0053] The invention provides a Noni endogenous Bacillus siamensis named: Bacillus siamensis QN 2 MO-1 was deposited at the China Center for Type Culture Collection on March 30, 2021, at Wuhan University in Wuhan, China, and the deposit number is CCTCC NO: M 2021305. Bacillus siamensis QN of the present invention 2 MO-1 (hereinafter referred to as "QN 2 MO-1") was isolated and screened from the fruit of the live Noni plant.

Abstract

The invention provides noni endophytic bacillus siamensis, which is named as bacillus siamensis QN2MO-1, is stored in the China Center for Type Culture Collection (CCTCC), and has the preservation number of CCTCC M 2021305. The strain has stable broad-spectrum antagonistic activity; and strong antibacterial effect on tomato fusarium wilt, banana fusarium wilt, cucumber fusarium wilt, pepper colletotrichum gloeosporioides, strawberry colletotrichum gloeosporioides, banana colletotrichum gloeosporioides, cabbage colletotrichum gloeosporioides, corn curvularia leaf spot, mango leaf blight, wheat scab, cryphonectria parasitica, mango pestalotiopsis leaf blight, rice blast, and colletotrichum gloeosporioides; its fermentation broth can effectively inhibit the infection of pathogen filaments on in-vitro leaves, fruits and the like, increases the safe sources of the effective components of the biocontrol agent, expands a new field for the prevention and treatment of tomato fusarium wilt and other plant diseases, and has good development and application prospects.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to the application of a noni endophytic bacillus siamese. Background technique [0002] Tomato (Lycopersicon esculentum Mill.) is one of the most consumed vegetables in the world. It is rich in nutrients such as lycopene and vitamin C. It is known as the natural "antioxidant" of human beings. It is a common star fruit with certain medicinal value. It has a large market demand, high economic benefits, and is widely planted around the world. However, the closedness of protected cultivation, successive years of heavy cropping, heavy fertilizer and heavy medicine and other management modes make diseases occur frequently, which seriously limits the development of tomato industry. Tomato wilt (Fusarium oxysporum (Schl.) f.sp. lycopersici (Sacc) Snyder et Hansen) is one of them, a highly specialized soil-borne vascular disease (Grattidge et al., 1982), which occurs mostly in toma...
