Abstract

The invention relates to bacillus subtilis Pc3 and a use of bacillus subtilis Pc3 in preparation of a fermentation supernatant for preventing and controlling plant pathogenic fungi, and relates to bacilli. The bacillus subtilis Pc3 has a preservation number of CCTCC NO: M2013470. The bacillus subtilis Pc3 can prevent and control plant pathogenic fungi such as gloeosporium musarum, paecilomyces variotii, sclerotinia sclerotiorum, alternaria longipes, trichoderma viride, rhizoctonia solani and fusaria. A rape sclerotinia sclerotiorum prevention and control pot experiment proves that the bacillus subtilis Pc3 has good biological-prevention and control effects and has prevention and control efficiency of 95.6%. The fermentation supernatant of the bacillus subtilis Pc3 can be prepared by simple processes and has a wide fungus inhibition spectrum and good biological prevention effects.

Description

technical field

[0001] The invention relates to a bacillus, in particular to a bacillus subtilis Pc3 and its application in preparing a fermentation supernatant for preventing and controlling plant pathogenic fungi. Background technique

[0002] With the resistance of plant diseases and insect pests to existing pesticides and the emergence of new diseases, it is required to continuously develop new pesticides. Microbial resources have always been the focus of research by agricultural workers, and finding new microbial-derived lead compounds or active products is one of the main means of pesticide creation. However, due to the long research and development time and high requirements for screening technology, it is becoming more and more difficult to screen and obtain new agricultural active substances. From the perspective of the process of new drug development, most of them still come from natural resources (Bevan et al.1995), including activity screening of microorganisms ...
