Embodiment Construction

[0019] Example 1

[0020] 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.

[0021] After mixing together, configure it into a liquid with a mass multiple of 400-600 times for spraying. (When using Shijunzi and galangal, use the alcohol extraction method to extract the extract, and use the extract when mixing.) After testing, the 400-600 times of the mixture is effective against the fungus genus Deuteromycotina monofilament shell Powdery mildew has an obvious inactivation effect, and the bactericidal effect is good, with an effective rate of 93.1%.

[0022]

[0023] Example 2

[0024] 15 parts of 35% high-fat film, 12 parts of 50% difenone, 15 parts of tangerine peel, 8 parts of talc, 8 parts of baicalein, 10 parts of 60% chlorothalonil, 8 parts of Shijunzi, and 10 parts of galangal.

Abstract

The invention discloses a compounded pharmaceutical composition for preventing and curing powdery mildew. The compounded pharmaceutical composition comprises the following components: by weight, 10-15 parts of 35% high-fat membrane, 8-12 parts of 50% drazoxolon, 10-15 parts of dried orange peel, 4-8 parts of talcum, 4-8 parts of baicalein, 6-10 parts of 60% chlorothalonil, 4-8 parts of quisqualis and 6-10 parts of galagal rhizome. The compounded pharmaceutical composition provided by the invention requires 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 of 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 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 leaves, but the les...
