Problems solved by technology

Pharmacological studies have shown that methyl eugenol has obvious antitussive, expectorant, sedative, and analgesic effects ("Study on the Pharmacological Effects of Methyl Eugenol", Journal of Traditional Chinese Medicine, 2000, 2, 79-81), but about methyl eugenol There are few studies on the antibacterial activity of phenols, and the application of phenolic fungicides in agriculture has not been reported

Embodiment 2

[0022] Embodiment 2: (1) Preparation of 10% methyl eugenol SL preparation:

[0023] Weigh 10kg of methyl eugenol, 8kg of alkylphenol polyoxyethylene ether, 22kg of ethanol, and 20kg of methanol; stir evenly in the reaction kettle at 50°C, then add 40kg of deionized water dropwise, and stir evenly.

[0024] (2) Determination of in vitro antibacterial activity of 10% methyl eugenol SL preparation

[0025] The 10% methyl eugenol SL preparation was prepared by the growth rate method, with Alternaria panax, Pestalotipassi sp., Rhizoctonoia solani, and Fusarium sp. Bacteria were tested for their antibacterial activity at dilutions of 500 and 1000 times for 120 hours. The antibacterial effect is shown in Table 2:

Abstract

The present invention relates to an application of methyl eugenol for controlling plant disease. Said methyl eugenol mainly is existed in extracts of natural plants of asarum and clove, etc, and has stronger effect for inhibiting and killing plant pathogenic eumycetes.

Description

1. Technical field [0001] The invention relates to a new application of a natural compound methyl eugenol in agriculture, in particular to the application of a plant source fungicide containing methyl eugenol. 2. Technical background [0002] The structural formula of methyleugenol (methyleugenol) is: [0003] [0004] Methyl eugenol is a known compound that can be purchased from the market. It mainly exists in the extracts of Chinese herbal medicines such as Asarum, cloves, and nutmeg. The process of extracting and separating methyl eugenol from Chinese medicinal materials has been compared Mature, for example, the steam distillation method specified in the Pharmacopoeia can obtain Asarum volatile oil, and then apply chromatography to separate and obtain methyl eugenol. [0005] Methyl eugenol is often used as a spice in baked foods, soft drinks, chewing gum, cheese, candy, pudding desserts, ice cream and other foods, and is also used in perfumes, shampoos, detergents, ...
