Use method of compound pharmaceutical composition for preventing powdery mildew

Abstract

The invention discloses a use method of a compound pharmaceutical composition for preventing powdery mildew. The use method includes the steps: A, preparing stock solution; B, adding water into the stock solution and mixing the stock solution and the water into dilution solution with 400-600 mass times; C, uniformly and thoroughly spraying the dilution solution to the front and the back of each leaf, focally spraying the dilution solution to the diseased leaves and protecting upper healthy leaves by spraying; D, supplementing fertilizers within 3 days after spraying to prevent early aging due to shortage of the fertilizers, and enhancing disease resistance of plants; E, performing smoking by the aid of sulfur in a greenhouse for 10 minutes everyday within 3 days after spraying. The stock solution comprises 35% of high-fat membranes, 50% of drazoxolon, dried orange peel, soapstone, baicalein, 60% of chlorothalonil, quispualis indica and galangal. 3.5-4kg of dilution solution is used per mu. After the fertilizers are applied, watering is omitted in cloudy days, more fresh air is supplied in sunny days, the relative humidity of the greenhouse is reduced, excessive temperature is prevented, and stuffiness is avoided. The compound pharmaceutical composition is simple to match and convenient to use, the effect of treating the cucumber powdery mildew is fine, and tests indicate that the 400-600 time solution of mixture has obvious deactivation for fungus deuteromycotina sphaerotheca powdery mildew and is fine in bactericidal effect.

Description

[0001] Technical field:

[0002] The invention relates to vegetable medicines, in particular to a method for using a compound medicine composition for preventing and treating powdery mildew.

[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 ...

Examples

Embodiment Construction

[0025] Example 1

[0026] 10 parts of 35% high-fat film, 8 parts of 50% chlorhexazone, 10 parts of tangerine peel, 4 parts of talc, 4 parts of baicalein, 6 parts of 60% chlorothalonil, 4 parts of Shijunzi, and 6 parts of galangal.

[0027] The method of use includes the following steps:

[0028] A, prepare the stock solution: the components of the stock solution are 35% high-fat film, 50% chlorhexazone, tangerine peel, talcum, baicalein, 60% chlorothalonil, gentile, galangal;

[0029] B. Add water to the stock solution to prepare a diluted solution with a mass ratio of 400-600;

[0030] C. The dosage per acre is 3.5-4kg. When spraying, it should be even and thoughtful, and the front and back of the leaves should be sprayed evenly. The focus is on the diseased leaves, and the upper healthy leaves should be sprayed to protect them;

[0031] D. Supplement fertilizer within 3 days after spraying to prevent defertilization and premature aging, and enhance plant disease resistance...
