Embodiment 1

[0015] Use the pharmaceutical composition of the present invention to prevent and treat grape downy mildew, plant 1 mu of vineyards in each group, and use the above-mentioned medicine for preventing and treating grape downy mildew in the stages of inflorescence separation, flowering, flower preservation and fruit preservation and expansion of grape growth The composition is sprayed on grapes. The spraying time is once every 11 days. For example, in the initial stage of grape downy mildew, continuous spraying for 2 days is enough.

[0016] A pharmaceutical composition for preventing and treating grape downy mildew. The active ingredients of the pharmaceutical composition include: 900 times liquid myclobutanil, 880 times liquid salicylic acid, 800 times liquid rotenone emulsifiable oil, 1000 times liquid tea saponin, 800 times liquid liquid phenthiastrobin. The mixing volume ratio is 2:3:3:1:3.

[0017] After adopting the above method, the size of each bunch of fruit is unifor...

Embodiment 2

[0019] The difference between this embodiment and the embodiment is that the pharmaceutical composition for preventing and treating grape downy mildew, the active ingredients of the pharmaceutical composition include: 800 times liquid myclobutanil, 1000 times liquid salicylic acid, 600 times liquid rotenone emulsifiable concentrate, 1200 times liquid tea saponin, 900 times liquid 50% dimethomorph wettable powder. The mixing volume ratio is 1:5:1:1:4.

[0020] After adopting the above method, the size of each bunch of fruit is uniform, and the yield is 3182 kg / mu. According to the national standard test, there is no pesticide residue on the grapes.

Embodiment 3

[0022] The difference between this embodiment and the embodiment is that the pharmaceutical composition for preventing and treating grape downy mildew, the active ingredients of the pharmaceutical composition include: 1100 times liquid myclobutanil, 800 times liquid salicylic acid, 1000 times liquid rotenone emulsifiable concentrate, A mixture of 800 times liquid tea saponin, 1000 times liquid garlic oil and cream bell. The mixing volume ratio is 4:1:3:1:2.

[0023] Wherein, the volume ratio of garlic oil and cream bell is 1:5.

[0024] After adopting the above method, the size of each bunch of fruit is uniform, and the yield is 3211 kg / mu. According to the national standard test, there is no pesticide residue on the grapes.

Abstract

The invention discloses a pharmaceutical composition for preventing and treating grape downy mildew. Effective ingredients of the pharmaceutical composition comprise myclobutanil, salicylic acid, derris cream and tea saponin. The pharmaceutical composition for preventing and treating the grape downy mildew, disclosed by the invention can be used for effectively preventing and treating the grape downy mildew, and grapes are full in fruit, high in yield and high in quality. Products can be free of pesticide residues, and thus, environmental pollution is avoided.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pharmaceutical composition for preventing and treating grape downy mildew. Background technique [0002] Grape downy mildew is a worldwide grape disease. It is distributed in various grape producing areas in my country, especially in rainy and humid areas. It is one of the main diseases of grapes. Grape downy mildew mainly damages leaves, and can also infect young tissues such as new shoots and young fruits. The leaves are damaged, and the first small grape downy mildew spots with light yellow water stains and unclear edges gradually expand into brown irregular or polygonal spots, and several spots connect to form large irregular spots. When the weather is humid, white downy mildew-like substances, which are the cyst peduncles and sporangia of the pathogen, are produced on the back of the lesions. When the disease is severe, the diseased leaves wither early and drop early. The you...
