Abstract

The invention discloses broad-spectrum disease resisting, growth promotion and stress resisting bacillus capable of preventing and treating tomato gray mold and tomato leaf mold and application of the broad-spectrum disease resisting, growth promotion and stress resisting bacillus. The broad-spectrum disease resisting, growth promotion and stress resisting bacillus is bacillus sp. WXCDD105, and is preserved in China General Microbiological Culture Collection Center (CGMCC); the preservation address is 3, No.1 Yard, Western Beichen Road, Chaoyang District, Beijing, the preservation date is May 25, 2016, and the preservation number is CGMCC No.12496. A biocontrol strain provided by the invention has ultraviolet-resisting and drought-resisting properties, has stronger prevention and treatment effects on the tomato gray mold and the tomato leaf mold, and can inhibit fungal diseases including wilt fusarium of a plurality of types of crops, corn foot root bacteria, rice wilt pathogens, acanthopanax senticosus root rot pathogens, corynespora cassiicolai, colletrichum orbiculare, exserohilum turcicum, tomato spot blight fungi, sunflower sclerotinia sclerotiorum, botrytis cinerea, fusarium oxysporum, verticillium fusarium, alternaria alternata and the like; the broad-spectrum disease resisting, growth promotion and stress resisting bacillus has a growth promotion effect on tomato seeds and seedlings and can also improve the quality of fruits and reduce the rotting rate.

Description

technical field [0001] The invention belongs to the technical field of microbes, and relates to a bacillus with strong antagonistic effect on tomato gray mold and leaf mold and the application thereof. Background technique [0002] Botrytis cinerea and leaf mold are a class of plant diseases with high incidence and rapid spread, especially in protected areas. They have become the main diseases during tomato cultivation and seriously affect the yield and quality of tomatoes. At present, chemical pesticides are still the main method in the control of Botrytis cinerea and leaf mold. Although chemical pesticides have played a huge role in plant disease control, their disadvantages have become increasingly prominent. Long-term heavy use of chemical pesticides will increase the resistance of bacteria. In addition, while killing germs, it also threatens beneficial microorganisms, destroys agricultural ecosystems, and endangers human health. Therefore, biological control with the...
