Abstract

The invention discloses a bdellovibrio bacteriovorus for preventing and curing rice bacterial diseases and application thereof. The invention can obtain bdellovibrio bacteriovorus BDFM05 by separation and ultraviolet mutation. The bdellovibrio bacteriovorus BDFM05 is combined with oligosaccharide to obtain bdellovibrio bacteriovorus for preventing and curing crop bacterial diseases. The inventionapplies bdellovibrio bacteriovorus BDFM05 to prevent and cure crop bacterial diseases for the first time. The bdellovibrio bacteriovorus prepared by the method has better rice bacterial diseases preventing and curing effect than common Saisentong, has no toxicity or pollution, is safe to natural enemies of crop diseases and pests, produces no pathogenic bacteria resistance, has no toxic or side effects to people and animals, improves the quality and safety of agricultural products and conforms to the requirements of people on healthy and green food and sustainable-development for agriculturalproduction.

Description

technical field

[0001] The invention belongs to the field of biotechnology, in particular to a Bdellovibrio for preventing and treating bacterial diseases of rice and its application. Background technique

[0002] Bacterial diseases of crops are common worldwide epidemic diseases, many of which are listed as plant quarantine diseases, which are more serious and difficult to control than fungal diseases. With global climate anomalies and local warming, typhoons, rainstorms and thermals occur year by year, creating external climatic conditions for the aggravation of bacterial diseases. With the reduction of cultivated land, the multiple cropping index and the multiple cropping area are increasing, and a large amount of cultivated land cannot be fallow and rotated, and the accumulation of pathogenic bacteria and pathogenic bacteria base in the soil is gradually increasing.

[0003] Bacterial diseases of rice are the main diseases in the growth process of rice, among which bact...
