preparation example Construction

[0021] A method for preparing pesticides for preventing and treating Alismatis leukoplakia, comprising the following steps:

[0022] Step 1: Weigh the raw materials by weight; the raw materials include the following components by weight: 3-12 parts of Coptis rhizome, 1-9 parts of Scutellaria baicalensis, 5-7 parts of Sophora flavescens, 1-4 parts of Houttuynia cordata, Cnidium 6-12 parts, Gardenia 3-9 parts;

[0023] Step 2: decocting the raw materials with water, filtering, and concentrating to obtain a concentrated solution;

[0024] Step 3: Add the concentrated solution into a suspending agent to obtain.

[0025] Further, the decocting condition is adding water 4-6 times the mass of the raw material and decocting 2-4 times, 2-3 hours each time.

[0026] Further, the concentrated solution has a density of 1.24-1.30 at 50°C.

[0027] Further, the raw materials include the following components in parts by weight: 5-10 parts of Coptis rhizome, 2-6 parts of Scutellaria baical...

Embodiment 1

[0031] The raw material composition of the present invention.

[0032]

Embodiment 2

[0034] Using the raw materials with the serial number of 1 in Example 1, a kind of pesticide for preventing and treating Alismatis leukoplakia is prepared, which specifically includes the following steps:

[0035] Step 1: taking the raw material by weight;

[0036] Step 2: Decocting 4-6 times the amount of the raw material in water twice, each time for 2 hours, filtering, and concentrating to obtain a concentrated solution with a density of 1.30 (50°C);

[0037] Step 3: Add the concentrated solution to 0.5% sodium alginate by mass of the concentrated solution to dissolve, stir evenly, and obtain the product.

Abstract

The invention discloses a preparation method of a pesticide for preventing and treating ramularia alismatis, and solves the problems in the prior art that the pesticide residue is easily caused and thus influences the quality of rhizoma alismatis as well as influences the environment. The preparation method comprises the following steps: weighing raw materials comprising the following components in parts by weight: 3-12 parts of coptis roots, 1-9 parts of baical skullcap roots, 5-7 parts of radix sophorae flavescentis, 1-4 parts of herba houttuyniae, 6-12 parts of common cnidium fruits and 3-9parts of cape jasmine fruits; adding water for decocting the raw materials, and performing filtration and concentration to obtain a concentrated solution; and adding a suspending aid to the concentrated solution to obtain the pesticide. The preparation method disclosed by the invention has the advantages that the process is simple, the operation is simple and convenient, process conditions are easy to control, and the pesticide prepared by adopting the method disclosed by the invention has exact action and obvious effects on prevention and treatment of the ramularia alismatis, can not cause the pesticide residue, can not influence the quality of the rhizoma alismatis, and can not generate pesticide resistance.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a preparation method of a pesticide for preventing and treating Alismatis leukoplakia. Background technique [0002] Alisma is the dried tuber of Alisma orientale (Sam.) Juzep. It is mostly produced in Sichuan and Fujian. When the stems and leaves begin to wither in winter, they are excavated, washed, dried, and fibrous roots removed. Alisma plants are perennial aquatic or marsh herbs. The whole plant is poisonous, and the underground tubers are more toxic. Tubers 1-3.5 cm in diameter, or larger. Anthers about 1 mm long, elliptic, yellow, or light green; achenes elliptic, or nearly oblong, seeds purple-brown, with protrusions. Produced in Heilongjiang, Jilin and other provinces. It grows in shallow water zones of lakes, river bends, streams, and ponds, and also grows in swamps, ditches, and low-lying wetlands. The flowers are larger and the flowering period...
