Example Embodiment

[0021] Example 1

[0022] The pharmaceutical composition consists of 3 parts of limonene, 4 parts of saponins extract, 15 parts of Portulaca oleracea extract, 0.13 parts of zinc chloride, 2 parts of cetearyl glucoside, and 0.6 parts of sodium alginate.

[0023] The saponin extract is prepared by grinding the saponin into a fine powder, and then adding a 25% ethanol aqueous solution with a volume fraction of 1g:10mL according to the material-to-liquid ratio, refluxing extraction at 40-50°C for 60min, and filtering Then concentrate to half of the original volume.

[0024] The Portulaca oleracea extract is prepared by the following method: After grinding garlic, the ratio of material to liquid is 1g: 10mL and 50% acetic acid aqueous solution and 0.5% of the weight of the purslane polyglutamine are added. Acid, reflux and extract at 35-40℃ for 80min, filter and concentrate to half of the original volume.

[0025] The preparation method is as follows:

Abstract

The invention belongs to the technical field of pesticides, and particularly relates to a pharmaceutical composition for preventing peanut rust by utilizing a herba portulacae extract and a preparation method of the pharmaceutical composition. The pharmaceutical composition comprises the following raw materials in parts by weight: 3 to 5 parts of limonene, 3 to 5 parts of a fructus gleditsiae extract, 12 to 15 parts of the herba portulacae extract, 0.13 to 0.15 part of zinc chloride, 1 to 2 parts of cetearyl glucoside and 0.6 to 0.8 part of sodium alginate. The pharmaceutical composition prepared by the method is good in suspension property, can form uniform suspension liquid, and is not layered and precipitated; the pharmaceutical composition prepared by the method can effectively preventpeanut rust and improve the peanut yield and quality.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pharmaceutical composition for preventing peanut rust by using purslane extract and a preparation method thereof. Background technique [0002] Peanut rust is one of the worldwide and explosive leaf fungal diseases. In my country, peanut rust is also one of the main problems in the peanut breeding process. Moreover, during the growth and development of peanuts, as the temperature rises, the occurrence of rust will be aggravated. Peanut rust may occur at all stages of growth, but it will be serious after the pod stage. The leaves are infected, and needle-sized rash-like white spots appear on the back of the leaves, and the leaves appear as small yellow spots. , as the lesion expands, the protrusions of the diseased portion are yellowish-brown. After the epidermis is broken, the rust-colored powder is exposed, that is, the pathogenic uredospore pile and uredospor...
