Embodiment Construction

[0019] Example 1

[0020] 10 parts of 50% thiram wettable powder, 8 parts of 75% chlorothalonil wettable powder, 10 parts of 35% Apulon (Ruidu mold), 4 parts of honeysuckle saponin, 4 parts of baicalin, 6 parts of indirubin, Honeysuckle 4 parts, coriander 6 parts.

[0021] After mixing together, configure it into a liquid with a mass multiple of 400-600 times for spraying. (When honeysuckle and coriander are used, use the alcohol extraction method to extract the extract, and use the extract when mixing.) After testing, the 400-600 times of the mixture has obvious killing effect on the fungus Deuteromycetes parasitic downy mildew. Active function, good bactericidal effect, the effective rate is 93.1%.

Abstract

The invention discloses a disease resistant drug for Chinese cabbage downy mildew. The disease resistant drug comprises the following components in parts by weight: 10-15 parts of 50% thiram wettable powder, 8-12 parts of 75% chlorothalonil wettable powder, 10-15 parts of 35% atibeprone (ridomil), 4-8 parts of honeysuckle saponin, 4-8 parts of baicalin, 6-10 parts of indirubin, 4-8 parts of honeysuckle, and 6-10 parts of Chinese parsley. The disease resistant drug has the advantages of simple preparation, 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 a drug for vegetables, in particular to a disease-resistant drug 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 enlarged, repeating bifurc...
