Embodiment 1

[0008] Under normal temperature and pressure, dissolve plant extracts such as berberine in berberine, astragalus polysaccharide in astragalus, aloe extract and other plant extracts into water in proportion to make a water solvent. The content of berberine in the water solvent is 2.0% and the astragalus polysaccharide is 1.0%. 5% of aloe extract, 5% of saponins, 5% of trifolium extract.

Embodiment 2

[0010] Under normal temperature and pressure, dissolve plant extracts such as berberine in berberine, astragalus polysaccharide in astragalus, aloe extract and other plant extracts into water in proportion to make a water solvent. The berberine content in the water solvent is 1.0% and the astragalus polysaccharide is 5.0%. , Aloe extract 10%, saponins 5%, Trifolium extract 10%.

Embodiment 3

[0012] Under normal temperature and pressure, dissolve plant extracts such as berberine in berberine, astragalus polysaccharide in astragalus, aloe extract and other plant extracts into water in proportion to make a water solvent. The water solvent contains 4.5% berberine and 10% astragalus polysaccharide , 10% aloe extract, 5% saponins, 20% trifolium extract.

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

[0014] The bactericidal effects of the above three embodiments of the present invention and conventional chemical agents (comparative examples) are compared 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 biological pesticides, in particular to a new technology for the synthesis and deep processing of plant-derived broad-spectrum fungicides of natural plant Coptis, Astragalus, Aloe and other plant active ingredients. Background technique [0002] According to statistics, my country’s pests, weeds and diseases perennially occur in an area of ​​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 used in large quantities because of their high efficiency and rapidity. The annual demand in our country amounts to more than 1 million tons of preparations, and more than 100 million tons of chemical liquids are sprayed annually. The area of ​​chemical control has exceeded 2.8 billion hectares per year, and it is increasing year by year. . Due to the high toxicity, high residue and unreasonable use of some chemica...
