Problems solved by technology

Especially in Ningxia and its adjacent areas in China, there are abundant resources of bitter beans and beef heart pods. At present, these resources have not been well utilized. According to the analysis of scientific researchers, this resource has important development and utilization significance, and has a good economic and social benefits
[0003] The status quo of biological pesticides: general biological pesticides have the disadvantages of slow efficacy and low knockdown rate compared with chemical pesticides. Some biological pesticides are harmful to humans and animals, cause phytotoxicity to crops, and have pesticide residues and pollute the environment.

Embodiment A

[0020] 1. Preparation of extract: 

[0021] (1) Extraction of matrine

[0022] The screened bitter beans are added to the degreasing machine for degreasing, and the degreased bitter beans are crushed to 460 meshes with a superfine pulverizer, added to the leaching axe, added to the soaking agent for leaching for 4 hours, put into the sedimentation tank for precipitation, and the clear liquid is added to a The stage vacuum distillation kettle is used for vacuum concentration, and the temperature is controlled at 55-60°C. When the concentration of total biological alkaloids is 50% through laboratory analysis, the primary concentration process is completed.

[0023] Take out the sediment in the sedimentation tank and put it into the leaching axe, add the soaking agent jfc-2 for secondary leaching, the weight ratio of the soaking agent to Sophora sophora is 0.3:1.75, take out the clear liquid after precipitation and add it to the first-stage vacuum distillation kettle Concentrat...

Abstract

The invention discloses a preparation method of environmental-protection biological pesticide. The biological pesticide comprises the following extracts and auxiliary agents in parts by weight: 150-200 parts of matrine, 100-150 parts of nicotine, 150-200 parts of cynanchum komarovii, 50-70 parts of triperygium wilfordii, 50-80 parts of cnidium fruits, 80-120 parts of Chinese honeylocust fruits, 50-80 parts of hairyvein agrimony, 40-60 parts of radix euphorbiae lantu, 50-80 parts of cortex pseudolaricis, 80-120 parts of melia azedarach fruits, 40-60 parts of cortex meliae, 80-100 parts of chrysanthemum cinerariifolium flowers, 50-80 parts of roots of Japanese stemona, 50-80 parts of thyme and 50-80 parts of baeckea frutescens; the auxiliary agents comprise a penetrant, an emulsifier and a stabilizer; adding amounts of the auxiliary agents into per ton of the extracts are as follows: 100kg of the penetrant, 150kg of the emulsifier and 130kg of the stabilizer. The environmental-protection biological pesticide disclosed by the invention causes no phytotoxicity or leaves pesticide residue to the crops; the environmental-protection biological pesticide is free of environmental pollution; the environmental-protection biological pesticide has the characteristics of high efficiency, low toxicity and long duration; moreover, the environmental-protection biological pesticide also has a relatively good yield-increasing effect.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an environment-friendly biopesticide, in particular to the field of a preparation method of an environment-friendly biopesticide. Background technique [0002] In recent years, a large number of investigations and researches on the insecticidal and antibacterial agricultural efficacy of matrine have been carried out at home and around the world. The results show that matrine has a wide range of uses in the field of pesticides. high. Especially in Ningxia and its adjacent areas in China, there are abundant resources of bitter beans and beef heart pods. At present, these resources have not been well utilized. According to the analysis of scientific researchers, this resource has important development and utilization significance, and has a good economic and social benefits. [0003] The status quo of biological pesticides: general biological pesticides have the disadvantages o...
