Embodiment 1

[0012] Use Bacillus pumilus to make wettable powder or granular inoculum according to the conventional biological control preparation process to prevent and control the disease of Ganoderma lucidum dark green. The specific test process is as follows:

[0013] 1. Source of the strain

[0014] 1.1 Source of pathogenic bacteria

[0015] In the Ganoderma lucidum cultivation base of Kangzhiyuan Ganoderma lucidum professional cooperative in Huangsongdian Town, Jiaohe, Jilin City, the pathogenic strains were obtained after the hyphae in the base were isolated and the back-grafting test followed Koch's law. PDA medium was used to cultivate pathogenic bacteria (recipe: 200g fresh potato, 1.0g glucose, 20g agar powder, H 2 O1000mL, pH natural), the medium was sterilized at 121°C for 25min before use.

[0016] 1.2 Source of bacterial strains

[0017] The soil was isolated from the surrounding soil of Ganoderma lucidum cultivation base in Kangzhi Garden Ganoderma lucidum professional c...

Embodiment 2

[0037] Various biological control bacteria agents such as wettable powder or granule can be made by using Bacillus pumilus.

Abstract

The invention discloses an application of Bacillus pumilus to prevention and treatment of diseases of ganoderma due to Trichderma atroviride as well as disease of other crops due to infection of Trichderma atroviride. Bacillus pumilus is used for inhibiting disease of ganoderma due to Trichderma atroviride, effectively controlling growth speed of mycelia of Trichderma atroviride, and especially controlling sporulation conditions of Trichderma atroviride effectively. Bacillus pumilus can be widely applied to inhibition of diseases of ganoderma and other fungus crops due to Trichderma atroviride, and novel wettable powder or granular microbial agents for biological control can be developed for controlling diseases of ganoderma and other fungus crops due to Trichderma atroviride.

Description

technical field [0001] The invention discloses the use of bacillus pumilus in preventing and treating the disease of trichoderma dark green ganoderma lucidum, which can also be used for preventing and treating the disease of trichoderma dark green infected by other fungi crops, and is applied in the technical field of pest control of crops. Background technique [0002] In recent years, fungus crops infected with Trichoderma dark green disease are more common, especially in Northeast China, Ganoderma lucidum in the cultivation process due to Trichoderma caused by the disease caused a very serious reduction in yield, which has a huge impact on the development of the entire industry. The laboratory test and field test of the pathogen Trichoderma by using conventional chemical agents and biocontrol fungicides purchased in the market have not achieved good results. Therefore, it is the main task to be realized by the present invention to provide a method that can effectively pre...
