Monacrosporium elegans bactericidal agent with nematode killing function and its preparation method and use thereof

Abstract

This invention relates to a Monacrosporium elegans bacteriostatic and its process and application, belonging to microbial pesticide technology region, with the preparing bacterial strain being Monacrosporium elegans, YMF1.00027, adopting normal process to prepare. Wherein, liquid fermenting culture medium dispense includes: 0.1% of glucose, 0.1% of ammonia sulfate, 0.05% of addex-magnesium, and liquor boiled from 100g potatoes, 0.001% of copperas, and filling waters to complement volume to 1L, PH6.5. The method for extracting effective composition to kill nemathelminth from liquid fermenting production is characterized by filtering fermented culture and dewatering supernatant with ammonia sulfate. The bacteriostatic is effective for killing Panagrellus redivivus and pine beam nemathelminths, and has broad aspect of application.

Description

Technical field: [0001] The invention relates to a Caenorhamona elegans fungus agent with a nematicide function, a preparation method and application thereof, and belongs to the technical field of biological pesticides. Background technique: [0002] Plant nematodes are a common plant disease worldwide. There are more than 70 known species of root-knot nematodes alone, which harm more than 3,000 plants and cause huge losses every year. According to the statistics of the Food and Agriculture Organization of the United Nations, the global losses caused by nematodes are as high as 100 billion U.S. dollars every year. In 2001, the losses caused by nematode damage to crops in my country were as high as 23.3 billion yuan. Pine xylophilus is known as smokeless forest fires, which have seriously occurred in some areas such as Jiangsu, Zhejiang, Guangdong, Shandong, Anhui, Hubei, Shanghai, Taiwan, Hong Kong, etc., and have a tendency to spread to the whole country. What's more serio...

Problems solved by technology

However, with the advancement of science and technology, it has been found that many chemical nematicides have side effects, which not only produce drug resistance, but also cause environmental pollution and endanger human health. Many of them have been banned or will be banned one after another.
