Embodiment Construction

[0015] Example 1

[0016] 10 parts of 55% Ankermanganese-zinc wettable powder, 8 parts of 30% potassium dihydrogen phosphate aqueous solution, 10 parts of polyethylene glycol solution, 4 parts of forsythin, 4 parts of chlorogenic acid, 6 parts of stachyine, silicon 4 parts of sol and 6 parts of calcium chloride.

[0017] After mixing together, it is configured into a liquid with a mass multiple of 400-600 times for spraying. (When using silica sol and calcium chloride, use the alcohol extraction method to extract the extract. When mixing, the extract is used.) After the test, 400-600 times the mixture is effective against the fungus imperfect fungus Parasitic Downy mold. Obvious inactivation effect, good bactericidal effect, effective rate of 93.1%.

[0018] Example 2

[0019] 15 parts of 55% Anke manganese zinc wettable powder, 12 parts of 30% potassium dihydrogen phosphate aqueous solution, 15 parts of polyethylene glycol solution, 8 parts of forsythin, 8 parts of chlorogenic acid...

Abstract

The invention discloses a composition for resisting downy mildew. The composition is composed of, by weight, 10-15 parts of 55% dimethorph wettable powder, 8-12 parts of 30% monopotassium phosphate solution, 10-15 parts of polyethylene glycol solution, 4-8 parts of phillyrin, 4-8 parts of chlorogenic acid, 6-10 parts of stachydrine, 4-8 parts of ludox and 6-10 parts of calcium chloride. The composition is simple in ratio, convenient to use and good in Chinese cabbage downy mildew treatment effect; through experiments and tests, 400-fold to 600-fold solutions of the mixture have a remarkable inactivating effect on the eubacterium deuteromycota parasitic downy mildew and are good in sterilizing effect.

Description

Technical field: [0001] The invention relates to a vegetable medicine, in particular to a composition for resisting downy mildew. Background technique: [0002] Parasitic downy mildew mainly harms cabbage. The mycelium is colorless and has no compartments. It grows between filament cells. The sucker penetrates into the cell to absorb water and nutrients. The sucker is sac-shaped, spherical or bifurcated. During vegetative reproduction, sporangia stalks emerge from the hyphae, protruding from the stomata, colorless, without septa, solitary or 2~4 bunches, 260~300μm long, slightly enlarged at the base of the main branch, repeated bifurcations Branches, 2 to 5 branches at the top, the main axis and the branches are at an acute angle, and the small stalks at the top are sharp and curved, with a sporangia at each end. The sporangia are colorless, single cells, oblong to ovoid, 24~27×15~20μm, germ tubes are usually produced from the side during germination, and zoospores are not form...
