Production method of disease-resistant medicine for treating cucumber powdery mildew

Abstract

The invention discloses a production method of a disease-resistant medicine for treating cucumber powdery mildew, comprising the following steps: A, material preparation: 27% high-fat membrane, 2% pyrimidine nucleoside agri cultural antibiotic, garlic extract, astragalus polysaccharide, baicalein, polyoxin, root of Chinese pulsatilla and dryopteris crasirhitom nakai are prepared; B, alcohol leaching of extracts of the root of Chinese pulsatilla and Cyrtomium Rhizome: the root of Chinese pulsatilla and Cyrtomium Rhizome are crushed, broken and washed; after air drying, the root of Chinese pulsatilla and Cyrtomium Rhizome are placed in a closed container; 60 wt% of an ethanol solution is added, the root of Chinese pulsatilla and Cyrtomium Rhizome are infiltrated and immersed for 18 hours and then are placed in a percolator; the percolator is a barrel structure, a cone is arranged at the bottom of the barrel structure, and switch equipment for dripping is disposed below the cone for extraction of medicinal materials; medicinal materials are uniformly placed in the barrel; an immersion fluid, water or wine, is added and drips slowly; a percolate is collected; and ethanol is heated and recovered to obtain an extract; and C, 27% high-fat membrane, 2% pyrimidine nucleoside agri cultural antibiotic, garlic extract, astragalus polysaccharide, baicalein and polyoxin are combined with the extract obtained from the step B, uniform stirring is carried out, and UV sterilization is conducted so as to obtain the disease-resistant medicine for treating cucumber powdery mildew. The medicine provided by the invention requires a simple composition ratio, is convenient to use and has a good effect of treating cucumber powdery mildew. Through tests, a liquid which accounts for 400-600 times the volume of the mixture has an obvious inactivation effect on fungi imperfecti Sphaerotheca powdery mildew, and has a good bactericidal effect.

Description

[0001] Technical field: [0002] The invention relates to vegetable medicines, in particular to a method for manufacturing cucumber powdery mildew disease-resistant medicines. [0003] Background technique: [0004] Cucumber powdery mildew, commonly known as "white hair disease", is the most serious damage to leaves, followed by petioles and stems, and generally does not harm fruits. In the early stage of the disease, small white powder spots on the front or back of cucumber powdery mildew-affected leaves will gradually expand into large white powder areas with inconspicuous edges, covering the leaf surface, as if sprinkled with white powder. Wipe off the white powder, it can be seen that the leaves are chlorotic, withered and yellow and brittle. When the disease is severe, the leaves are covered with white powder and become off-white until the whole leaf dies. After powdery mildew infects petioles and tender stems, the symptoms are similar to those on the leaves, but the...
