Embodiment 1

[0008] Under normal temperature and normal pressure, plant extracts such as berberine in Coptis chinensis, astragalus polysaccharide in astragalus, and aloe extract are dissolved in water in proportion to make a water solvent. The content of berberine in the water solvent is 2.0%, and the content of astragalus polysaccharide is 1.0%. , Aloe extract 5%, saponins 5%, clover extract 5%.

Embodiment 2

[0010] Under normal temperature and normal pressure, plant extracts such as berberine in Coptis rhizome, astragalus polysaccharide in astragalus, and aloe extract are dissolved in water in proportion to make a water solvent. The content of berberine in the water solvent is 1.0%, and the content of astragalus polysaccharide is 5.0%. , Aloe extract 10%, saponins 5%, clover extract 10%.

Embodiment 3

[0012] Under normal temperature and normal pressure, plant extracts such as berberine in Coptis chinensis, astragalus polysaccharide in astragalus, and aloe extract are dissolved in water in proportion to make a water solvent. The content of berberine in the water solvent is 4.5%, and astragalus polysaccharide is 10%. , Aloe extract 10%, saponins 5%, clover extract 20%.

[0013] The finished extract solution of the embodiment of the present invention can be applied in the field after being diluted 400-600 times with water.

[0014] The bactericidal effect of above-mentioned three embodiments of the present invention and conventional chemical agent (comparative example) is contrasted below:

Abstract

The invention discloses a broad-spectrum bactericide of a plant source. The broad-spectrum bactericide of the plant source comprises the raw materials by weight percentage as follows: 0.5-4.5% of berberine, 0.5-20% of astragalus polysaccharide, 0.5-20% of radix tetrastigme extract, 0.5-20% of aloe extract, 0.5-20% of saponins and the balance of water. The broad-spectrum bactericide of the plant source generated after compounding the plant extracts extracted from pure plants has the advantages of efficiency, low cost, environment-friendliness, difficulty to generate drug resistance and innocuity to people and livestock.

Description

technical field [0001] The invention relates to the technical field of biopesticides, in particular to a new technology for synthesis and deep processing of botanical broad-spectrum fungicides and other active ingredients of natural plants such as Coptis chinensis, astragalus, aloe and the like. Background technique [0002] According to statistics, the perennial area of ​​pests and weeds in my country is about 400 million hectares. Due to the use of pesticides, my country's annual direct economic loss is reduced by about 50 billion yuan. Chemical pesticides are widely used due to their high efficiency and speed. In my country, the annual demand is more than 1 million tons of preparations, and the annual spraying of chemical solutions is more than 100 million tons. The area of ​​chemical control has exceeded 2.8 billion hectares per year, and it is increasing year by year. . Due to factors such as high toxicity, high residue and irrational use of some chemical pesticides, wh...
