Abstract

The invention relates to streptomyces with double functions of preventing diseases and killing pests, an application and a culture method thereof, and a biocontrol agent thereof, and belongs to the technical field of plant pest control. In the invention, an endophytic streptomyces MS001 with bacteriostatic activity is separated and obtained. The fermentation liquor has stronger bacteriostatic activity on Botryosphaeria dothidea, Colletotrichum gloeosporioides, Phomopsis mali, Rhizoctonia cerealis, Gaeumannomyces graminis, Botrytis cinerea, Fusarium graminearum, Fusarium oxysporum and Colletotrichum karstii, and the bacteriostatic objects have broad-spectrum property; and the fermentation liquor has the function of inhibiting the growth of plant pests such as helicoverpa armigera and monochamus alternatus larvae. Therefore, the streptomyces MS001 can prevent and control some diseases and pests on apple trees, garden plants, vegetables and food crops.

Description

technical field [0001] The invention relates to a streptomycete with dual functions of disease prevention and insecticide, its application, a cultivation method and a biocontrol agent, and belongs to the technical field of plant disease and insect pest control. Background technique [0002] Endophytic actinomycetes are widely distributed in the roots, stems, leaves, fruits and seeds of plants. A large number of studies have shown that actinomycetes isolated from plants have great application value. [0003] The Australian research team isolated more than 60 strains of actinomycetes from the roots of wheat, and screened out the strains for preventing and controlling wheat take-all disease (Gaeumannomyces graminis var. CM.Isolation and identification of actinobacteria from surface-sterilized wheat roots[J].Applied and Environmental Microbiology,2003,69(9):5603~5608.). Liang Yaping and others isolated 29 strains of endophytic actinomycetes from wild plants, among which the con...
