Penicilliumgriseofulvum XJ-EP-058 strain as well as microbial preparation resisting banana vascular wilt and application thereof

Abstract

The invention discloses a penicilliumgriseofulvum XJ-EP-058 strain as well as a microbial preparation resisting banana vascular wilt and application thereof, belonging to the technical field of microbial pesticides. The strain is penicilliumgriseofulvum XJ-EP-058 with the preservation number of CGMCC (China General Microbiological Culture Collection Center) No.5467. The microbial preparation, containing the strain, for resisting the banana vascular wilt is obtained by test tube seed culture, liquid seed culture for the strain and liquid fermentation culture for the strain. The strain and the microbial preparation, containing the strain, for resisting the banana vascular wilt have obvious in-vitro and in-vivo preventing effects and have the germination inhibition rate reaching 100% to spores of banana vascular wilt bacteria, and the average diameter of bacteriostatic zones to the banana vascular wilt bacteria is 14.5mm; and a result of a greenhouse potted living organism test shows that the strain and the microbial preparation have the average control effect reaching 74.38% on the banana vascular wilt bacteria. The microbial preparation has the advantages of low raw material cost and simple and feasible production process.

Description

technical field [0001] The invention relates to a banana endophytic fungus and its anti-banana fusarium wilt microbial agent, application and preparation method of the microbial agent, belonging to the technical field of microbial pesticides. Background technique [0002] Banana vascular wilt (Banana vascular wilt), also known as Panama disease and yellow leaf disease, is caused by the semi-known fungus Hyphomycetes, Tumorasporum, Fusarium oxysporum, Fusarium oxysporum Cuban specialization [ Fusarium oxysporum f.sp. cubes (E.F.Smith) Snyder] is a devastating disease of bananas. In May 2007, my country included banana fusarium wilt in the list of imported plant quarantine pests. At present, Fusarium wilt of banana is widely distributed in banana producing areas in Asia, Africa, Australia, South Pacific and tropical America. In 1960, my country first discovered banana wilt on plantains in Guangxi. In the late 1970s, it occurred successively in Guangdong, Fujian, Hainan, Y...

Problems solved by technology

However, long-term or excessive use of a single pesticide can easily lead to disease resistance, greatly reducing the control effect, increasing the amount of pesticide residues, killing a large number of natural enemies, destroying the micro-ecological balance of farmland and polluting the environment. While developing high-efficiency and low-toxic chemical pesticides, great attention has also been paid to the development of biological pesticides. At present, biological control is considered to be the most promising control method in the control of agricultural diseases and insect pests, among which microbial preparations are an important type.
