Abstract

The invention discloses a method for preparing a fungicide containing coptis chinensis and ethylicin. A coptis chinensis concentrated liquor and ethylicin are adopted as main raw materials; a fermented product of the coptis chinensis and the ethylicin and an adjuvant are prepared into the fungicide containing the coptis chinensis and the ethylicin; the fermented product of the coptis chinensis and the ethylicin comprises the following components in parts by weight: 50-80 parts of the coptis chinensis concentrated liquor, 20-30 parts of the ethylicin, 5-15 parts of a surfactant, 1-10 parts of a microbial fermentation adjuvant and 20-40 parts of a weakly acidic solution. The fungicide prepared by the method is a botanical fungicide; and due to complementary advantages of the coptis chinensis and the ethylicin, the pesticide effect is improved, the dosage of a chemical agent can be reduced, and the ecological environment is improved.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and in particular relates to a preparation method of a fungicide containing coptis and allicin. Background technique: [0002] In recent years, with the continuous improvement of people's living standards, pollution-free vegetables have become the development direction of the current vegetable industry, because the long-term use of chemical pesticides in large quantities to prevent and control vegetable pests and bacteria has caused pollution to vegetables and soil, affecting long-term development, and some even seriously threaten people's health. Therefore, for pollution-free vegetables, it is necessary to choose pesticides reasonably, give priority to biological pesticides, and choose chemical pesticides reasonably, and choose chemical pesticides with high efficiency, low toxicity and low residue. [0003] At present, the use of biopesticides is more advocated. Biopesticides use natural pl...
