Abstract

The invention provides bacillus velezensis for inhibiting virus and promoting plant growth and application of a bacillus velezensis SNB55 strain in prevention and treatment of plant virus diseases andplant fungal diseases and promotion of plant growth. The bacillus velezensis for inhibiting virus and promoting plant growth and the application of the bacillus velezensis have the beneficial effectsthat the bacillus velezensis has no toxicity and pathogenicity, is safe to human and livestock, is environment-friendly, and has high stress resistance and stable antibacterial activity; the bacillusvelezensis can inhibit phytopathogens such as bacillus cereus, tobacco mosaic virus, tomato yellow leaf curl virus, fusarium wilt of cucumbers, tobacco target spot pathogens, phytophthora capsici, rice sheath blight disease and botrytis cinerea, can be secrete indoleacetic acid to promote seed germination and plant growth; and the strain is a multifunctional biocontrol bacterium and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of microbial control, and relates to a microbial control technology for tomato virus diseases, in particular to a strain for inhibiting tobacco mosaic virus (TMV) and tomato yellow leaf curl virus (Tomato yellow leaf curl virus, TYLCV) Bacillus velezensis and its application. Background technique [0002] Plant viral pathogens are known as "plant cancer", which is the second largest plant disease after plant fungal diseases, causing significant economic losses to agricultural production. There are many kinds of plant viruses, among which the tobacco mosaic virus (TMV) is one of the main poisonous sources causing tomato and tobacco and other Solanaceae plants. In recent years, tomato yellow leaf curl virus (Tomato yellow leaf curl virus, TYLCV) spreads rapidly in my country, and shows an increasing trend year by year, posing a serious threat to my country's tomato production. For a long time, the prevention...
