Embodiment 1

[0015] Embodiment 1 The bactericide containing mustard seed extract of the present invention consists of 40 parts of mustard seed extract, 10 parts of eucalyptus oil, 22 parts of absolute ethanol, 8 parts of carboxymethylcellulose, 14 parts of emulsifier op-10, 6 parts of corn oil were prepared, and the preparation method of the mustard seed extract was as follows: black mustard seeds and yellow mustard seeds were soaked in ethanol with a mass fraction of 50% preheated to 40°C and kept at a mass ratio of 1:2 In the aqueous solution for 20 hours, then the mustard seeds are mixed with an ethanol aqueous solution with 4 times the mass of mustard seeds and a mass fraction of 80%, and ether with 15% of the mass of mustard seeds in a sealed container, and the ultrasonic wave with a frequency of 50 kHz and a voltage of 50V is carried out. Ultrasonic treatment for 20 minutes; after the ultrasonic treatment, the mixture was heated and distilled for 45 minutes to remove the solids.

Embodiment 2

[0016] Embodiment 2 The bactericide containing mustard seed extract of the present invention consists of 30 parts of mustard seed extract, 5 parts of eucalyptus oil, 50 parts of dehydrated alcohol, 3 parts of carboxymethyl cellulose, 25 parts of emulsifier op-10, 10 parts of soybean oil are prepared, and the preparation method of the mustard seed extract is as follows: black mustard seeds and yellow mustard seeds are soaked in ethanol with a mass fraction of 55% preheated to 45°C and kept at a mass ratio of 1:1 In the aqueous solution for 18 hours, then the mustard seeds are mixed with ethanol aqueous solution with a mass fraction of 75% and 10% mustard seed mass in a sealed container, and the frequency is 60 kHz, and the voltage is 80V. Ultrasonic Ultrasonic treatment for 10 minutes; after the ultrasonic treatment, the mixture was heated and distilled for 60 minutes to remove the solids.

Embodiment 3

[0017] Embodiment 3 The present invention contains the fungicide of mustard seed extract, which consists of 10 parts of mustard seed extract, 20 parts of eucalyptus oil, 10 parts of absolute ethanol, 10 parts of carboxymethyl cellulose, 10 parts of Tween 20, soybean oil 15 parts were prepared, and the preparation method of the mustard seed extract was as follows: black mustard seeds and yellow mustard seeds were soaked in an aqueous ethanol solution with a mass fraction of 60% preheated to 30°C and kept at a mass ratio of 1:3 After 24 hours, the mustard seeds were mixed with 5 times the mass of mustard seeds and 70% ethanol aqueous solution, and 20% ether of mustard seeds in a sealed container, and the ultrasonic treatment was carried out with a frequency of 40 kHz and a voltage of 50V. 25 min; after the ultrasonic wave is finished, the mixture is heated and distilled for 50 min to remove the solids, and the product is obtained.

Abstract

The invention discloses a bactericide containing a mustard seed extract. The bactericide is prepared from the following active ingredients in parts by weight: 10-50 parts of mustard seed extract, 5-20 parts of eucalyptus oil, 10-50 parts of anhydrous alcohol, 3-10 parts of carboxymethyl cellulose, 10-25 parts of emulsifier, and 2-15 parts of suspending agents, wherein the mustard seed extract is prepared by the following steps: soaking black mustard seeds and yellow mustard seed into an ethanol water solution according to certain proportion, placing the soaked mustard seed extract into the ethanol water solution and ether mixed solution, performing ultrasonic treatment and heating and distilling to obtain the mustard seed extract. The bactericide contains multiple effective constituents contained in the mustard seeds, such as allyl isosulfocyanate, and other small-molecular phenols and esters such as methyl ester and butyl ester, and the bactericide has more broad-spectrum bactericidal effect and can be effectively applied to sterilization of crops or soil.

Description

technical field [0001] The invention relates to a fungicide, in particular to a fungicide containing mustard seed extract. Background technique [0002] Brassica mustard is an annual or biennial herb of the Brassicaceae family (scientific name: Brassica juncea), and is a famous specialty vegetable in China. Mustard greens are rich in vitamin A, vitamin B family, vitamin C and vitamin D. Mustard greens contain a large amount of ascorbic acid, which is a highly active reducing substance and participates in important redox processes in the body. The use of mustard has the effect of refreshing the mind and relieving fatigue; secondly, it also has the function of detoxification and detumescence, which can resist infection and prevent the occurrence of diseases, inhibit the toxicity of bacterial toxins, promote wound healing, and can be used to assist in the treatment of infectious diseases; After being pickled, it has a special umami taste and fragrance, which can promote the di...
