Embodiment 1

[0022] Dissolve 180g of carboxymethyl cellulose in 711.997g of distilled water, then add 18g of starch, 90g of nepeta volatile oil, 0.002g of brassinolide, 0.001g of gibberellin, and mix well to obtain a cream. Coat the surface of the sponge cloth with a coating amount of 180g / m2, and dry at 35°C to obtain the drug core 2. Put the drug core 2 on the double-sided tape 3, and stick the bottom isolation layer 1 under the double-sided tape 3, which is polyurethane Ester, the drug core 2 is pasted with a surface isolation layer 4 that is sulfuric acid paper, and the volatile oil of Nepeta nepeta is taken from the whole herb of Nepeta nepeta, dried in the shade, cut into small sections of 0.2 cm, extracted by steam distillation for 2 hours, and the volatile oil is collected to obtain Nepeta nepeta. Volatile oil.

Embodiment 2

[0024] Dissolve 200g of carboxymethylcellulose in 679.997g of distilled water, then add 20g of starch, 100g of Nepeta volatile oil, 0.002g of brassinolide, 0.001g of gibberellin, and mix well to obtain a cream. Coating on the surface of sponge cloth, the coating amount is 190g / m2, and drying at 35°C to obtain the drug core 2, the drug core 2 is pasted on the double-sided tape 3, the double-sided tape 3 is attached to the bottom isolation layer 1, and the drug core 2 is on the Paste the surface isolation layer 4. For the volatile oil of Schizonepeta, take the whole herb of Schizonepeta, dry it in the shade, cut it into 0.5 cm sections, extract it by steam distillation for 2 hours, collect the volatile oil to obtain the volatile oil of Schizonepeta.

Embodiment 3

[0026] Dissolve 250g of carboxymethylcellulose in 619.997g of distilled water, then add 20g of starch, 110g of Nepeta volatile oil, 0.002g of brassinolide, 0.001g of gibberellin, and mix well to obtain a cream. Coating on the surface of sponge cloth, the coating amount is 190g / m2, and drying at 35°C to obtain the drug core 2, the drug core 2 is pasted on the double-sided tape 3, the double-sided tape 3 is attached to the bottom isolation layer 1, and the drug core 2 is on the Paste the surface isolation layer 4. For the volatile oil of Schizonepeta, take the whole herb of Schizonepeta, dry it in the shade, cut it into 0.8cm sections, extract it by steam distillation for 2 hours, collect the volatile oil, and obtain the volatile oil of Schizonepeta.

[0027] In order to better verify the actual application effect of the present invention, the following examples are used to illustrate the field efficacy test effect of the Nepeta volatile oil patch of the present invention.

Abstract

The invention discloses a Chenopodium ambrosioides volatile oil patch and a preparation method thereof to solve the problems of large residual quantity, easy disease recurrence, frequent medication and the like of common branch disease control methods. The Chenopodium ambrosioides volatile oil patch comprises 7-15wt% of Chenopodium ambrosioides volatile oil, 0.0001-0.0003wt% of a plant growth regulator, 1.5-3wt% of starch, 15-25wt% of carboxymethylcellulose sodium, and the balance distilled water. The preparation method comprises the following steps: dissolving carboxymethylcellulose sodium in distilled water, sequentially adding starch, the Chenopodium ambrosioides volatile oil, brassinolide and gibberellin, uniformly mixing to obtain a cream, coating the surface of a sponge cloth with the cream, drying at 35DEG C to obtain a drug core, plastering the drug core onto a double-sided tape, plastering a bottom separation layer onto the lower surface of the double-sided tape, and plastering a surface separation layer onto the drug core. The Chenopodium ambrosioides volatile oil patch has the advantages of use convenience, small pollution and long efficacy period, and overcomes the disadvantages of previous medication modes when the Chenopodium ambrosioides volatile oil patch is used for controlling tree branch diseases.

Description

technical field [0001] The invention belongs to the field of botanical fungicide production, and in particular relates to a plant extract Nepeta nepeta volatile oil patch and a preparation method. Background technique [0002] Nepeta is a plant of Chenopodiaceae, which is widely distributed in temperate to tropical regions all over the world, and usually grows in wastelands such as roadsides and river banks and in farmland. The whole herb of Schizonepetae is used as medicine, which has the effects of expelling wind, dehumidification, killing insects, stimulating menstruation, and relieving pain. Nepeta nepeta is rich in volatile oil, which has the functions of antibacterial, insecticidal, inhibiting the growth of cancer cells and treating gastric ulcer, especially has a significant inhibitory and bactericidal effect on plant pathogenic fungi, and has a wide antibacterial spectrum. But the volatile oil of Nepeta nepeta has not been prepared yet. [0003] In agricultural and...
