Embodiment 1

[0021] Embodiment 1 Preparation of botanical natural fungicide

[0022] Take the patchouli essential oil with a purity of 98.0%, account for 23.0% of the 97.0% cinnamon essential oil, 30.0% of the perilla essential oil of 98.0%, 12.0% of the eucalyptus essential oil of 95.0%, and 12.0% of the eucalyptus essential oil with a ratio of 22.0%. Cube essential oil accounts for 5.0% and 95.0% citronella essential oil accounts for 30.0% of the vegetable oil composition after mixing uniformly, and then uniformly dispersed in 12.0% polyoxyethylene sorbitan monooleate and water according to the proportion of 2.0% In a solvent, mix and stir at 50°C and 1500r / min for 20min to obtain an emulsified formulation with bactericidal effect.

Embodiment 2

[0023] Embodiment 2 Preparation of botanical natural fungicides

[0024] Get the patchouli essential oil that purity is 98%, account for 12.0%, 99.0% perilla essential oil account for 16.0%, 97.0% eucalyptus essential oil account for 20.0%, 97.0% with the ratio of 10.0%. % Litsea cubeba essential oil accounts for 42.0% and 95.0% citronella essential oil accounts for 10.0% after the plant essential oil composition of composition mixes evenly, then disperses in according to the ratio of 10.0% by 18.0% sorbitan monocinnamate and water Mix and stir for 20 minutes at 50°C and 1500r / min in the solvent formed to obtain an emulsified preparation with a variety of plant essential oils as functional components, and obtain a plant-derived natural fungicide with environmental protection, safety, high activity, and no residue bactericidal effect .

Embodiment 3

[0025] The preparation of embodiment 3 botanical natural fungicides

[0026]Take the patchouli essential oil with a purity of 98.0%, and in a ratio of 6.0%, cinnamon essential oil with a purity of 98.0% accounts for 6.0%, perilla essential oil accounts for 26.0%, 970% eucalyptus essential oil accounts for 16.0%, and 98.0% mountain Cube quince essential oil accounts for 32.0% and 95.0% citronella oil accounts for after the vegetable oil composition of 20.0% composition mixes evenly, then according to the ratio of 15.0%, evenly disperses in 21.0% polyoxyethylene sorbitan monooleate (tween -80) and water in a solvent, mixed and stirred at 55°C and 1000r / min for 15min to obtain an emulsified formulation with bactericidal effect.

Abstract

The invention relates to a botanical natural disinfectant, which is characterized in that the disinfectant is prepared by mixing active components including patchouli essential oil and composite of various plant essential oils and solvent; wherein, the active components are prepared by mixing 0.5 to 30.0 percent of patchouli essential oil, cinnamon essential oil, perilla essential oil, eucalyptus essential oil, litsea cubeba essential oil and citronella essential oil and are used for preventing the crop disease caused by plant pathogenic bacteria. Compared with the original disinfectant, the botanical natural disinfectant has the advantages of good broad spectrum sterilization, safety to non-target organism and environment-friendly biodegradation.

Description

technical field [0001] The invention relates to a botanical natural fungicide, in particular to a botanical fungicide used for the prevention and treatment of crop diseases caused by plant pathogenic bacteria, and a preparation method thereof, belonging to plant pesticides. technical background [0002] Plant diseases often cause significant losses to agricultural production. However, 80% of plant diseases are caused by plant pathogenic bacteria. How to effectively prevent and treat plant fungal diseases has always been one of the problems to be solved in agricultural production. The traditional method is to control by applying chemically synthesized pesticide products. However, due to the long-term and large-scale use of chemical pesticides, their residues have also caused great damage to the ecological environment system. At the same time, due to the diversity, variability and drug resistance of pathogenic bacteria, it has also brought difficulties to the long-term contro...
