Embodiment 1

[0054] Example 1: Weigh 10 kg of betel nut, add 8 L of ammonia water to moisten it for 10 minutes, extract it with 120 L of ether for 1 hour, and precipitate the ether extract, and wash the residue with ether three times, 20 L each time, combine the ether solution, and evaporate to dryness at room temperature. Extract the dry extract with 20L of chloroform, precipitate, filter, wash with chloroform three times, 8L each time, combine the chloroform extracts, and dry in vacuum to obtain arecoline.

Embodiment 2

[0055] Embodiment two: the insecticidal and bactericidal microemulsion of thymol and arecoline provided by the present invention is composed of the following components in percentage by weight:

[0056] Thymol 10%,

[0057] Arecoline 10%,

[0058] Ethanol 20%,

[0059] Farm Milk 6025%,

[0060] Nisin 3%,

[0061] The remainder is water;

[0062] Add 1 kg of thymol original drug, 1 kg of arecoline, and 2 kg of ethanol into the reaction kettle and stir until they are completely dissolved, then add 500 g of Nongru 602 and 300 g of nisin in turn, and stir in the preparation obtained under high-speed stirring at room temperature Add water to a total weight of 10 kg, stir evenly at a constant temperature, and take out the reactant after 1 hour, which is the insecticidal and bactericidal microemulsion of thymol and arecoline.

Embodiment 3

[0063] Embodiment three: a kind of insecticidal and bactericidal suspoemulsion containing thymol and arecoline provided by the present invention is made up of the following components in weight percentage:

[0064] Thymol 15%,

[0065] Arecoline 10%,

[0066] Kaolin 20%,

[0067] Tripolyglyceryl Monostearate 5%,

[0068] Sodium lignosulfonate 2%,

[0069] Sodium Lauryl Sulfate 1%

[0070] Xanthan Gum 1.5%,

[0071] Mineral oil 0.3%,

[0072] The remainder is water;

[0073] Add 1.5 kg of thymol technical substance, 1 kg of arecoline, 2 kg of kaolin, 200 g of sodium lignosulfonate, 500 g of tripolyglycerol monostearate, 100 g of sodium lauryl sulfate, 150 g of Add 10 grams of xanthan gum, 30 grams of mineral oil, add water to a total weight of 10 kilograms, stir evenly, grind finely in a sand mill, and the resultant is the insecticidal and bactericidal suspoemulsion of thymol and arecoline.

Abstract

The invention relates to an insecticidal and bactericidal agent with thymol and arecoline, in particular to a formula of the insecticidal and bactericidal agent with thymol and arecoline and a preparation method of the insecticidal and bactericidal agent. The insecticidal and bactericidal agent is prepared from, by weight, 1-45% of thymol, 1-25% of arecoline and the balance additives. Because few insecticidal and bactericidal pesticides exist on the market, the insecticidal and bactericidal agent will save lots of cost for vast farmers once being produced and used, and the main ingredients, namely, thymol and arecoline, used by the insecticidal and bactericidal agent are plant source ingredients extracted from the nature, can be decomposed in the natural environment, cause no pollution to crops or the environment, and belong to green pesticide. Due to the two active ingredients, namely, thymol and arecoline, the synergistic interaction effect is achieved, and it is avoided that diseases and insects resist to the agent and the control object is simplex in the use process.

Description

technical field [0001] The invention relates to an insecticide and fungicide, in particular to a formulation of thymol and arecoline insecticide and fungicide, and preparation methods of several formulations of the insecticide and fungicide. Background technique [0002] Thymol is a phenol derivative of p-cymene, which is slightly soluble in water. Its molecular formula is C 10 h 14 O, the chemical name is 2-isopropyl-5-methylphenol, and its structural formula is: [0003] [0004] Thymol is named after it was first extracted and isolated from thyme. It is a colorless translucent crystal, easily soluble in ethanol, ether, acetic acid, chloroform and benzene, has a certain fragrance and has a strong bactericidal effect. On June 19, 2013, the European Commission has approved the marketing of thymol as a plant protection product. It is obvious that thymol has high safety and low toxicity. Thymol is currently also widely used in other aspects. For example, due to its anti...
