Problems solved by technology

At present, after the peanut seedlings are ready, the medicines are used in time to prevent diseases. Usually, spraying or drenching methods are used to apply the medicines. Triadimefon and carbendazim are mostly used. The application amount is large, and it is easy to cause drug residues, which is not good for the environment and human health.

Embodiment 1

[0021] The composition of the pharmaceutical composition: 2 parts of limonene, 5 parts of saponin extract, 8 parts of garlic extract, 0.1 part of zinc chloride, 1.5 parts of cetearyl glucoside, and 0.7 part of sodium alginate.

[0022] The saponins extract is prepared by the following method: Grind saponins into fine powder, then add 25% ethanol aqueous solution according to the ratio of solid to liquid 1g:10mL, reflux extraction at 40-50°C for 60min, filter Concentrate to half the original volume.

[0023] The garlic extract is prepared by the following method: after grinding the garlic, adding acetic acid aqueous solution with a volume fraction of 50% according to the solid-liquid ratio of 1g:10mL, refluxing and extracting at 35-40°C for 80min, filtering and concentrating to half of the original volume.

[0024] The preparation method is as follows:

[0025] (1) Mix the saponins extract and garlic extract in parts by weight, then add zinc chloride, heat up to 35-40°C, keep...

Embodiment 2

[0028] The composition of the pharmaceutical composition: 2 parts of limonene, 4 parts of saponins extract, 10 parts of garlic extract, 0.12 parts of zinc chloride, 1.5 parts of cetearyl glucoside, and 0.8 parts of sodium alginate.

[0029] The preparation method is the same as in Example 1.

Embodiment 3

[0031] The composition of the pharmaceutical composition: 2.5 parts of limonene, 5 parts of saponin extract, 9 parts of garlic extract, 0.12 part of zinc chloride, 1.5 parts of cetearyl glucoside, and 0.5 part of sodium alginate.

[0032] The preparation method is the same as in Example 1.

Abstract

The invention belongs to the technical field of pesticides, and in particular relates to a limonene-based pharmaceutical composition for preventing peanut root rot and a preparation method thereof. The pharmaceutical composition comprises the following raw materials in parts by weight: 2-3 parts of limonene, 3-5 parts of saponin extract, 8-10 parts of garlic extract, 0.1-0.12 parts of zinc chloride, 1-1 part of cetearyl glucoside 2 parts, 0.6-0.8 parts of sodium alginate. The pharmaceutical composition prepared by the invention has good suspensibility and can form a uniform suspension without stratification and precipitation; the pharmaceutical composition prepared by the invention can effectively prevent peanut root rot and improve peanut yield and quality.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a limonene-based pharmaceutical composition for preventing peanut root rot and a preparation method thereof. Background technique [0002] Peanut is a common oil crop in the north. As a root-growing crop, the quality of the root system often determines the yield. Root rot may occur in various growth stages of peanuts. Infection before emergence can cause rotten seeds and buds; infection in the seedling stage can cause root rot and seedling withering; after adult plant, it can cause root rot, stem base rot and pod rot. The aboveground part of the diseased plant mainly shows short stature, poor growth, yellowing of leaves, and finally the whole plant withers. Peanut root rot is a soil-borne disease, and the pathogen can infect crops with the diseased residue overwintering in the soil until the second year, or spread by seeds. At present, after the peanut seedlings...
