Abstract

The invention provides a novel biological broad-spectrum pesticide and a preparation method thereof. The novel biological broad-spectrum pesticide is prepared by mixing and fermenting ginger, hot pepper, pepper, tobacco leaves and soybean milk fermenting liquid according to a certain weight ratio. The novel biological broad-spectrum pesticide adopts natural plants and probiotics as a core, is prepared through pure biological fermentation, is not added with any chemically synthetic ingredients, has the characteristics of broad spectrum, safety, environmental friendliness and the like, can be applied to preventing and controlling insect damage of organic food, green food and agricultural exports, is a new-generation green pesticide, can be widely applied to controlling agricultural and forest pests of vegetables, fruit trees, gardening flowers, tea gardens and fields, has obvious effect of killing various pests, such as Heliothis armigera, aphid, lice, grubs, red spiders, size insects, Meloidogyne and the like, of crops in agriculture and forestry, is particularly applicable to production of green pollution-free agricultural products and agricultural exports, and can meet requirements on detection of any residues.

Description

technical field [0001] The invention relates to a biological fermentation process, in particular to a novel biological broad-spectrum insecticide 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" in the development and use of pesticides and "pollution-free" p...
