Abstract

The invention discloses a broad-spectrum disease-resistant, growth-promoting, and stress-resistant bacillus for preventing and treating tomato gray mold and leaf mold and its application. The broad-spectrum, disease-resistant, growth-promoting, and stress-resistant bacillus is Bacillus sp. WXCDD105 was deposited in the General Microorganism Center (CGMCC) of the China Committee for the Collection of Microbial Cultures. The preservation address is No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing. The preservation date is May 25, 2016, and the preservation number is CGMCC No. 12496. The biocontrol bacterial strain of the present invention has the characteristics of UV resistance and drought resistance, has a strong control effect on tomato gray mold and leaf mold, and can inhibit various crop fusarium wilt, corn stem rot, rice blight, and Acanthopanax Add root rot, cucumber brown spot, cucumber anthracnose, corn leaf spot, tomato blight, sunflower sclerotinia, strawberry gray mold, Fusarium oxysporum, Verticillium, Alternaria and other fungal diseases , and has a growth-promoting effect on tomato seeds and seedlings, and can also improve fruit quality and reduce rot 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...
