Problems solved by technology

[0006] Antibiotic fungicides are a kind of fungicides with better application, but because antibiotics are obtained by microbial fermentation, it is difficult to obtain a high-efficiency strain, and there are similar problems to microbial fermentation, so only a few species are widely used at present

Embodiment 1

[0033] Example 1. Preparation of bactericide

[0034] Take 60 grams of Xanthium, 30 grams of Cork, 30 grams of Cnidium, 30 grams of Sophora flavescens, 60 grams of Alum, 15 grams of Honeysuckle, 15 grams of Honeysuckle, 15 grams of Ginkgo Leaf, 20 grams of Pulsatilla and 15 grams of Asarum, according to tradition Traditional Chinese medicine boiling method: After mixing, add 2000ml, 1000ml and 1000ml of water in sequence, and boil 3 times, each time to 200~300ml, the filtrate of 3 times is combined and heated and concentrated to 500ml to make a liquid, which is filtered by multiple layers of gauze. After the bacteria filter is filtered and sterilized, the bactericide LS-1 is obtained.

Embodiment 2

[0035] Example 2. Toxicity determination of fungicides

[0036] 1. Material

[0037] 1.1, test materials

[0038] Test strains Phytophthora sojae, Phytophthora capsici, Phytophthora capsici, Alternaria solani, Fusarium oxysporum Schlecht., Alternaria Alternaria alternata, Exserohilum turcicum, Botrytis cinerea, Fusarium graminicola and Pyricularia oryzae are all common commercial strains.

Embodiment 3

[0053] Example 3 The effect of fungicides on the formation and germination of spores (cysts) of plant pathogens

[0054] 1. Test materials

[0055] Pseudoperonospora cubensis, Phytophthoracapsici, Fusarium oxysporum, Alternaria alternata, and Pyricularia oryzae are all commercial strains.

[0056] 2. Test method

[0057] The effect of the test agent on the germination of spores (capsules): mix the spores or sporangia of the tested plant pathogenic bacteria into 50-60 spores per 10 times the field of view, and then use the spore suspension to dilute the chemical agent, and test before dilution The chemical agent is prepared into a mother liquor of 150, and then the calculated amount of the medicine to be added in 2ml is diluted with the spore suspension to 2ml and added to the wells of the 24-well cell culture plate. The bacterial suspension without the agent is used as the control. Cover the lid and place it in a constant temperature incubator for 24h or 48h, investigate and calcu...

Abstract

The Chinese herbal medicine germicide is prepared with ten kinds of Chinese medicinal materials including cocklebur fruit, phellodendron bark, cnidium fruit, flavescent sophora root, alum, etc. in certain weight proportion. The Chinese herbal medicine germicide has broad spectrum bacteriostasis activity and high safety on plant and human body, and may be used widely in producing green food material.

Description

Technical field [0001] The invention relates to a Chinese herbal medicine fungicide. Background technique [0002] Currently, the fungicides used in agricultural production mainly include chemical fungicides and biological fungicides. [0003] The main problems caused by the use of chemical fungicides for pest control are environmental pollution, pesticide residues and increased resistance to pests. In particular, the residues of pesticides in food have caused great harm to human health. This problem is particularly prominent in the prevention and control of vegetable diseases. [0004] Biological fungicides are preparations that can prevent and treat plant diseases by using living organisms or active ingredients produced by organisms, and chemically synthesized substances with a natural compound structure. Mainly divided into microbial biocides, antibiotics (mainly refers to microbial metabolites or their biomimetic compounds) and plant-derived fungicides. Biological fungicides ...
