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

[0053] Embodiment 3, bactericide is to the influence of phytopathogenic bacteria spore (capsule) formation and germination

[0054] 1. Test materials

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

[0056] 2. Test method

[0057] The effect of the test agent on the germination of spores (sacs): make the spores or sporangia of the plant pathogenic bacteria to be tested into 50-60 spores per 10 times field of view, and then dilute the chemical agent with the spore suspension. The chemical agent is made into 150 mother liquor, and then according to the calculated amount of drug to be added in 2ml, it is diluted to 2ml with spore suspension and added to the well of a 24-well cell culture plate. Cover and place in a constant temperature incubator for 24h or 48h and then investigate and calculate the spore germination rate.

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] At present, the fungicides used in agricultural production mainly fall into two categories: chemical fungicides and biological fungicides. [0003] The main problems brought about by the use of chemical fungicides for pest control are environmental pollution, pesticide residues and increased pest resistance. In particular, pesticide residues in food have caused great harm to human health, and this problem is particularly prominent in the prevention and control of vegetable diseases. [0004] Biological fungicides are preparations that can prevent and control plant diseases prepared by using living organisms or active ingredients produced by organisms, as well as chemically synthesized substances with natural compound structures. It is mainly divided into microbial living fungicides, antibiotics (mainly referring to microbial metabolites or their biomimetic com...
