Production method of disease resistant drug for Chinese cabbage downy mildew

Abstract

The invention discloses a production method of a disease resistant drug for Chinese cabbage downy mildew. The production method comprises the following steps: A. a stock solution is prepared, and comprises the following components: 50% thiram wettable powder, 75% chlorothalonil wettable powder, 35% atibeprone (ridomil), honeysuckle saponin, baicalin, indirubin, honeysuckle and Chinese parsley; B. extracting solutions of the honeysuckle and the Chinese parsley are digested by alcohol; C. the 50% thiram wettable powder, the 75% chlorothalonil wettable powder, the 35% atibeprone (ridomil), the honeysuckle saponin, the baicalin and the indirubin are compounded with the extracting solutions of the step B for evenly mixing, and are ultravioletly disinfected to obtain the drug resisting the Chinese cabbage downy mildew. The production method has the advantages of simplicity, simple application method of used products, simple preparation of the used products, convenience in use and good effect on treatment of the Chinese cabbage downy mildew; through the test of experiments, 400-600 times of liquid of the mixture has obvious inactivation effect on fungus fungi imperfecti and peronospora parasitica; the disinfection effect is good.

Description

[0001] Technical field: [0002] The invention relates to vegetable medicines, in particular to a method for preparing disease-resistant medicines for cabbage downy mildew. [0003] Background technique: [0004] Cabbage downy mildew, the disease mainly damages the leaves, initially light yellow or yellow-green lesions, which expand to yellowish brown, polygonal or irregular. When the air is humid, a white to off-white frosty mold layer is produced on the diseased part of the back of the leaf. The pathogen of this disease is: parasitic downy mildew, the mycelium is colorless, without septum, grows between the silk cells, and stretches into the cell to absorb water and nutrients by the haustoria, and the haustoria is cystic, spherical or bifurcated. During vegetative reproduction, cyst peduncles are produced from the hyphae, protruding from the stomata, colorless, without septa, solitary or in bundles of 2-4 roots, 260-300 μm long, the base of the main branch is slightly en...
