A kind of Streptomyces lincolens that can control peach brown rot and its application

Abstract

The present invention relates to a kind of Streptomyces lincolens that can prevent and treat peach brown rot, which was deposited in the General Microorganism Center of China Microbial Culture Collection and Administration Commission on December 17, 2020, and the preservation number is CGMCC No. 21377, and also relates to the Streptomyces lincolinis Application in the control of peach brown rot. The Streptomyces lincolens of the invention has a strong inhibitory effect on various plant pathogens such as peach brown rot on a flat plate, and its volatile metabolites have a good control effect on the growth of peach brown rot pathogens. The strains have potential commercial development and application value in disease biological control practices. The strain also has broad-spectrum antagonistic activity, showing strong bacteriostatic effect against pathogenic bacteria such as citrus canker and tobacco angular leaf spot, and also against pathogenic fungi such as tobacco botrytis, apple rot and tobacco root black rot. Has a good antibacterial effect.

Description

Technical field [0001] The invention involves the field of fruit and tree disease prevention and control, and more specially, it involves a Lincoln chain mold and its application that can prevent and treat peach brown rot. Background technique [0002] my country's peach tree cultivation area and peach output ranks first in the world, and it is an important big country. Tao is one of the main fruit resources in my country. It is planted nationwide. It is currently mainly distributed in East China and North China. It is not only nutritious and sweet. It also brings huge economic benefits. According to statistics, in 2015, the total output and total consumption of peaches in my country were 13.11 million t, 13.2 million t, respectively, accounting for about 66 % of the world's total peaches. However, the fruit rate of peaches in my country is relatively low, mainly due to the infection of pathogenic microorganisms, which leads to rotten fruit, which seriously affects the quality of...

Problems solved by technology

Not only that, the damage caused by the brown rot fungus of peaches is even more serious in the process of storage, transportation and consumption after harvest, and it has brought huge losses to the edible value of fruits and the economic income of fruit farmers.

[0004] At present, the control of peach brown rot is mainly based on chemical agents, which have the advantages of simple operation and low cost, but the use of chemical fungicides is likely to lead to enhanced drug resistance of pathogenic bacteria and environmental pollution, and may endanger ecological security and environmental protection. human health
