Abstract

The invention provides a novel biological broad spectrum bactericide and a preparation method thereof. The bactericide is prepared from garlic, onion and bitter gourd fermentation liquor according to a certain weight proportion by mixing and fermenting. The biological broad spectrum bactericide takes natural plants and probiotics as cores, is prepared by pure biological fermentation and is not added with any chemical synthetic component, so that the bactericide has the advantages of high efficiency, no harm, no pollution, no side effect, broad antibacterial spectrum and long effect, has double effects on prevention and control of multiple diseases caused by bacteria, can be used for prevention and control of diseases of organic food, green food and exported agricultural products, is a new-generation green bactericide, can be widely applied to disease control of vegetables, fruit trees, gardening flowers, tea gardens and field agriculture and forestry, and has obvious inhibiting and eliminating effects on multiple pathogenic fungi and bacteria of agricultural and forest crops.

Description

technical field [0001] The invention relates to a biological fermentation process, in particular to a novel biological broad-spectrum fungicide and a preparation method thereof. Background technique [0002] For a long time, the problem of environmental pollution caused by the extensive use of chemical pesticides has become increasingly serious. Chemical pesticides also pose a threat to beneficial organisms because they are not selective. Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants. [0003] As the public's requirements for "green food" and "pollution-free food" are getting higher and higher, the market's demand for pollution-free and naturally degradable ecological pesticides is gradually increasing. From the perspective of the development of pesticide science, "returning to nature" and "pollution-free" pesticides in the development and use of pes...
