Embodiment 1

[0039] Preparation of raw materials:

[0040] The preparation of described garlic extract:

[0041](1) Raw material pretreatment: After removing impurities and peeling the fresh garlic seeds, wash them with clear water; (2) Slurry: crush the clean garlic seeds obtained in (1) at high speed in a grinder for 2 minutes, and beat them into Homogenize; squeeze out the garlic juice, filter twice, and put the filtrate in a clean container for later use; (3) add distilled water to the filter residue at a weight ratio of 1:12 to water, and extract at room temperature (25°C-30°C) for 4 hours; (4) Filtration: the extract obtained in (3) is filtered, and the filtrate is for subsequent use; (5) Filtrate is mixed: the initial filtrate obtained in (2) is mixed with the filtrate after the extraction obtained in (4); (6) Store for later use: put the mixed filtrate obtained in (5) in a clean vessel, seal it away from light and store it at low temperature (because the filtrate contains a certai...

Embodiment 2

[0051] The preparation step of raw material is with embodiment 1.

[0052] (1) By volume ratio of each extracted Chinese medicine source extract, namely garlic: Houttuynia cordata: Purslane: Artemisia argyi Ginkgo biloba: 5:1.5:2:1, each extract is mixed and shaken, Into the initial dosing. Then add about the 5% fine sulfur powder that the weight that has sifted is the total weight of the initial dosing solution, fully stir and evenly to form the initial fungicide stock solution. (2) When using this product, take 430 ml of this product, add about 35 liters of clean water, stir well, and then spray it for use.

Embodiment 3

[0054] The preparation step of raw material is with embodiment 1.

[0055] (1) With the extracts of the above-mentioned extracted Chinese medicine sources, according to the volume ratio of garlic: Houttuynia cordata: purslane: artemisia mugwort and ginkgo biloba: 5:2:1.5:1 volume ratio, mix and shake the 6 kinds of Chinese medicinal material extracts Mix evenly to form the initial dosing solution; then add about 3% fine sulfur powder with a sifted weight of the total weight of the initial dosing solution, fully stir and evenly form the initial fungicide stock solution. (2) When using this product, take 400 ml of this product, add about 35 liters of clean water, stir well, and spray it for use.

Abstract

The invention discloses a biopesticide bactericide prepared from Chinese herbs and the use of the biopesticide bactericide. The bactericide is prepared from the following components in percentage by weight: 45%-55% of garlic extract, 15%-25% of heartleaf houttuynia herb extract, 10%-20% of purslane extract, 8%-15% of extract of folium artemisiae argyi, gingko and sweet wormwood, and 3%-5% of sulfur powder. The biopesticide bactericide prepared from Chinese herbs has a strong killing effect on pathogenic bacteria of pythium rot, damping off, rice blast and the like of crops such as rice, wheat and vegetables; the bactericide is capable of achieving the purpose of preventing and treating fungus and bacterial disease, and also capable of promoting the expression of a defensive enzyme system in the bodies of plants, improving the disease resistance of the plants and promoting the increase of production of crops; meanwhile, the prevention and treatment effect of the bactericide on soil-borne diseases propagated via soil is above 90%.

Description

technical field [0001] The invention relates to the technical field of pesticide fungicides, in particular to a biopesticide fungicide made from Chinese herbal medicine and its application. Background technique [0002] As people's requirements for environmental livability and food safety are increasing, the environmental and food pollution problems caused by the excessive use or improper use of chemical pesticides have gradually attracted people's attention. Broad-spectrum pesticides with high efficiency, low toxicity, low residue, and environmental compatibility that meet the concepts of environmental protection, health, and sustainable development have become the direction of pesticide development and research today. The production of new biotype special or broad-spectrum fungicides with traditional Chinese medicine source plants as raw materials is non-toxic, non-polluting and non-residual, and fully meets people's requirements for green and pollution-free food.
