Example Embodiment

[0023] Example 1

[0024] 15 parts of 70% ethyl phosphorous aluminum manganese zinc wettable powder, 12 parts of cork, 6 parts of Daqingye, 6 parts of frost, 9 parts of clove oil, 4 parts of azoxystrobin.

[0025] A. Preparation: 70% by mass of ethyl phosphorous aluminum manganese zinc wettable powder, cork, green leaf, frost, clove oil, azoxystrobin;

[0026] B. Alcohol extraction of Phellodendron chinense and Daqingye extract:

[0027] The cork and green leaves were broken, washed, dried, and placed in a closed container, and 75% by mass ethanol solution was added, soaked for 12 hours, and then put into the percolator. The device is a barrel structure with a cone underneath. Under the cone is a device with a switch that can drip water. It is used for extracting medicinal ingredients. Put the medicinal materials evenly into the barrel and add the soaking liquid: water or wine, slowly dripping, Collect the percolate, heat and recover the ethanol to obtain the extract;

[0028] C. Add ...

Abstract

The invention discloses a manufacturing method of a drug for inhibiting pseudoperonospora cubensis rostov. The method comprises the following steps: A, preparing raw materials comprising an aluminum tris-o-ethyl phosponate/mancozeb wettable powder with the mass percentage of 70%, cortex phellodendri, folium isatidis, a pesticide named Shuangbeier, a clove oil, and copper azoxystrobin; B, carrying out alcohol extraction on cortex phellodendri and folium isatidis to obtain an extraction liquid: crushing and breaking cortex phellodendri and folium isatidis, washing cleanly, after drying operation in air, placing in a closed container, adding an ethyl alcohol solution with the mass percentage of 75%, infiltrating and soaking for 12 hours with tightly covering, and then filling into a percolator, wherein the percolator is a device having a barrel structure, having the bottom provided with a conical body, and having a switch which is connected below the conical body and can drip water, and the percolator is used for extracting medicinal components; and putting the medicinal materials evenly into the barrel, adding a soaking liquid of water or alcohol, slowly dripping, collecting the percolate, and heating and recycling ethyl alcohol to obtain the extraction liquid; and C, adding the 70% fosetyl aluminum manganese zinc wettable powder, the pesticide named Shuangbeier, the clove oil and copper azoxystrobin into the extraction liquid obtained in the step B, and mixing and stirring evenly to obtain the drug for inhibiting pseudoperonospora cubensis rostov. The manufacturing method is simple, and the prepared product is simple to prepare a mixture, is easy to use, and has good effect on treatment of cucumber downy mildew.

Description

[0001] Technical field: [0002] The invention relates to a medicine for vegetables, in particular to a preparation method of a medicine for inhibiting cucumber downy mildew. [0003] Background technique: [0004] Cucumber downy mildew occurs at the seedling stage, and irregular chlorotic yellow-brown spots appear on the front of the cotyledon, and the diameter of the spot is 0.2-0.5 cm. When it is wet, gray-brown moldy matter is produced on the back of the spot, and the cotyledon turns yellow when it is severe. dry. The disease of adult plants usually starts from the front of the greenhouse. The diseased plants first appear water-soaked, light green small spots on the back of the middle and lower leaves, which are not visible on the front, and then the spots gradually expand and appear on the front. Lesions are polygonal. Under humid conditions, a purple-brown or taupe sparse mold layer appears on the back of the lesions. In severe cases, the lesions become one piece a...
