Production method of biopesticide

Abstract

The invention provides a production method of biopesticide, comprising the steps of sorting, dipping, enzymolysis and boiling. Specifically, the purchased Chinese herbal medicine with the functions of sterilization, deinsectization and killing pests is separated according to grades; the obtained raw materials are dipped, boiled and / or performed with enzymolysis to take juice; mixed liquid medicine is obtained by stirring, low-temperature squeezing and filtering as well as high speed centrifugation; after high-pressure filtration and concentration extraction, biopesticide of which the volume concentration is 30-40% is prepared; during dipping, the raw material are dipped in a large pool for 3-5 hours; during boiling, the raw material are boiled at the temperature of 80-100 DEG C; and during high-pressure filtration, mixed liquid medicine is filtered under the pressure which is less than or equal to 100 kg to obtain the filtered liquid medicine. The biopesticide prepared with the method of the invention has no toxicity or harm on people and livestock, does not damage nature, does not pollute environment, can replace chemical and chemical industry synthetic pesticides used at present at home and abroad, can be used for sterilization, deinsectization and killing pests for crops and vegetables.

Description

technical field [0001] The invention relates to pesticides, in particular to a biopesticide production method that can be widely used for insecticidal, sterilizing and harmful removal of various crops, fruit trees and vegetables. Background technique [0002] Today's international society mainly uses chemically synthesized pesticides to kill insects, sterilize, and eliminate pests to solve crops, fruit trees, vegetables and other pests and diseases. Although chemically synthesized pesticides have solved some problems, such pesticides are highly toxic and have a long residual time, which is harmful to humans and animals. It has a destructive impact on nature, air, land, and the ecological environment. If it is used for a long time, it will bring devastating disasters to humans. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production method of biopesticide. The biopesticide prepared by this method is scientifi...
