Problems solved by technology

[0007] These mainly focus on a certain strain or a certain product. The control of banana fusarium wilt cannot be prevented in a certain link. It needs to be prevented and controlled from all links in the whole process of banana production. If there is a problem in one link, it will Lead to the failure of control measures, no matter how effective the disease control products are

Embodiment 1

[0020] 1. The source and identification of antagonistic marine bacteria TC-1

[0021] Through the plate confrontation test, from more than 1,800 strains of marine microorganisms, after preliminary and re-screening screening, it was found that the bacteriostatic effect on the banana Fusarium wilt No. Bacillus amyloliquefaciens.

[0022] 2. Antagonize the antibacterial spectrum of marine bacteria TC-1

[0023] TC-1 not only has a good antibacterial effect on Fusarium wilt of banana, but also has an inhibitory effect on other 14 kinds of plant pathogenic bacteria, and its antibacterial spectrum is broad.

[0024] Table 1 Antibacterial spectrum of TC-1

[0025]

[0026] 3. Antagonize the antibacterial effect of marine bacteria TC-1 fermentation broth

[0027] (1) Inhibition of spore germination of Fusarium wilt of banana

[0028] Using the concave slide method, the inhibitory effect of the sterile fermented liquid diluted 40 times on the conidia of Banana Fusarium wilt race...

Abstract

The invention discloses a method for comprehensively preventing and treating banana fusarium wilt by applying marine antagonistic bacteria, which includes preparing antibacterial marine microorganisms, cultivating bagged banana seedlings, planting banana seedlings and managing them later. The method of the invention controls every link in the whole process of banana production, and achieves good control effect. CCTCC NO:M2014227 20140525

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for comprehensively preventing and controlling banana wilt by using marine antagonistic bacteria. Background technique [0002] Banana wilt is a soil-borne disease caused by Fusarium oxysporum f.sp.cubense (E F.Smith) Snyder et Hansen (anamorph)], which has become serious enough to harm Asia, Africa, and South America Banana producing areas in more than 20 countries and regions. In my country's Guangdong, Fujian, Hainan, Guangxi, Taiwan, and parts of Yunnan, the harm is quite serious. Especially in Panyu, Zhongshan, and Dongguan of Guangdong Province, the harm is very serious, leading to the destruction of banana orchards, and serious occurrences occur in some areas such as Huadu, Zhuhai, Zhaoqing, Xinyi, Zhanjiang, and the incidence rate in some places reaches 96-100%. Destroy the entire banana industry. [0003] Banana Fusarium Wilt is a cancer of bananas. At ...
