Embodiment 1

[0023] A botanical pesticide preparation for preventing and treating botrytis cinerea, prepared by the following process steps:

[0024] (1) Extraction of carvacrol

[0025] The oregano is obtained by steam distillation to obtain oregano volatile oil, and then the volatile oil is alkali-dissolved and liquid-separated to obtain a water-phase alkali solution. After acidifying the alkali solution, it is extracted with ethyl acetate to obtain an extract, and finally removed by atmospheric pressure distillation. Organic solvent, the remaining oil is carvacrol;

[0026] (2) Preparation of Chinese herbal medicine composition extract

[0027] The medicinal extract is obtained by using the Chinese herbal medicine Scutellaria baicalensis, Nepeta nepeta, perilla, chrysanthemum chinensis, and sinensis as raw materials, through ion impregnation, ultrasonic vibration extraction, and vacuum low-temperature concentration;

[0028] (3) Product preparation

[0029] Weigh 5% carvacrol, 5% ext...

[0033] (1) Extraction of carvacrol

[0034] With embodiment 1;

[0035] (2) Preparation of Chinese herbal medicine composition extract

[0036] The medicinal extract is obtained by using the Chinese herbal medicine Nepeta Nepeta, Huoxiang, Cedar, Prunella vulgaris, and oregano as raw materials through ion impregnation, ultrasonic vibration extraction, and vacuum low-temperature concentration;

[0037] (3) Product preparation

[0038] Weigh 5% carvacrol, 10% extract of traditional Chinese medicine composition, 5% fatty acid polyoxyethylene ester (emulsifier), 2% sodium polyacrylate (dispersant), dodecylbenzenesulfonic acid (emulsifier) ) 4%, silicone oil 0.1% (defoamer), polyvinyl alcohol (solvent) 1%, phenylphenol polyoxyethyl ether (dispersant) 2%, deionized water to 100%, after mixing The soluble agent of 15% carvacrol and Chinese medicine com...

Embodiment 3

[0041] A botanical pesticide preparation for preventing and treating botrytis cinerea, prepared by the following process steps:

[0042] (1) Extraction of carvacrol

[0043] With embodiment 1;

[0044] (2) Preparation of Chinese herbal medicine composition extract

[0045] The traditional Chinese medicinal materials of Labiatae, such as peppermint, perilla, chrysanthemum, ear dig grass, and Huoxuedan, are used as raw materials to obtain the drug extract through ion impregnation, ultrasonic vibration extraction, and vacuum low-temperature concentration;

[0046] (3) Product preparation

[0047] Weigh 3% of carvacrol, 15% of traditional Chinese medicine composition extract, 4% of sodium lignosulfonate (dispersant), 5% of sapinberry powder (emulsifier), and 0% of silicone compound (active agent). .1%, xanthan gum (active agent) 0.2%, ethylene glycol (thickener) 2%, calcium alkylbenzenesulfonate (emulsifier) ​​2%, deionized water to 100%, mix After homogeneity, the 18% carvacr...

Abstract

The invention provides a plant-derived pesticide preparation for preventing and controlling gray mold of crops, which is prepared by mixing carvacrol and extracts of traditional Chinese medicinal materials of labiatae according to a weight ratio of 1 to (1-10) and through a conventional pesticide process and with auxiliary agents, wherein the traditional Chinese medicinal materials of labiatae include one or more of radix scutellariae, fineleaf schizonepeta herb, wrinkled gianthyssop herb, radix salviae miltiorrhizae, herba menthae, folium perillae, herba elsholtziae, scabrous mosla herb, spica prunellae, decumbent bugle herb, scutellaria indica herb, glechoma hederacea herb, origanum vulgare herb and herba pogostemonis. The plant-derived pesticide preparations can prevent and control graymold of crops by rationally mixing the carvacrol and the extracts of traditional Chinese medicines, has an obvious prevention and control effect, can improve crop yield, is environmentally friendly and free of any residue, and is an ideal substitute for chemical pesticides in the development of modern green ecological agriculture.

Description

technical field [0001] The invention belongs to the application technical field of agricultural disease and insect pest control, and in particular relates to a botanical pesticide preparation for preventing and treating gray mold of crops. Background technique [0002] The long-term use of chemically synthesized pesticides in my country has not only affected the export of agricultural products, Chinese herbal medicines, tobacco leaves, melons and fruits, and tea leaves in my country, but also caused serious deterioration of the natural ecological environment. Produce corresponding toxicity, seriously endanger the health of the whole people. Therefore, prohibiting the use of highly toxic pesticides, reducing the use of chemically synthesized pesticides, and developing, promoting and using pollution-free and environmentally friendly natural biological pesticides have broad market prospects. In recent years, due to single and irrational use of drugs, many diseases have develope...
