Abstract

A strain of Bacillus velezensis (Bacillus velezensis) SNB55 that suppresses viruses and promotes plant growth and application thereof of the present invention is characterized in that the name of the strain is Bacillus velezensis (Bacillus velezensis) SNB55 and the strain is effective in preventing and treating plant virus diseases and plant fungi. Diseases, application in promoting plant growth. The beneficial effect of the present invention is that: a strain of Bacillus Veles that suppresses viruses and promotes plant growth and its application is non-toxic, non-pathogenic, safe for humans and animals, friendly to the environment, strong in stress resistance, and resistant to stress. Bacterial activity is stable; it can inhibit Bacillus cereus, tobacco mosaic virus and tomato yellow leaf curl virus, cucumber fusarium wilt, tobacco target spot fungus, capsicum phytophthora, rice sheath blight and tomato botrytis cinerea and other plants The pathogenic bacteria can secrete indole acetic acid to promote seed germination and plant growth. It is a multifunctional biocontrol bacterium and has broad application prospects.

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...
