Embodiment 1

[0042] Embodiment 1: the production of 20% eugenol and 4% allicin composition emulsifiable concentrate A

[0043] Accurately and quantitatively weigh 212 kilograms of the original drug of 94% eugenol, and then weigh 100 kilograms of the extracted mother liquor whose allicin content is 4%. Mix the two active ingredients in 2M 3 Mix thoroughly in the mixing tank.

[0044]Accurately weigh 10 kg of ascorbic acid and put into the above 2M 3 Pour into jar and mix well again. Add 100 kg of emulsifier Well205 and 578 kg of ethyl acetate to the blending tank accurately, and mix thoroughly in the blending tank. Stirring was continued for 1 hour. The oil preparation product of 1 ton of eugenol and allicin composition is prepared.

[0045] Sampling analysis showed that the content of eugenol was 20.01%, and the content of allicin was 4.10%. The product is divided into aluminum cans coated with barrier material, 5 kg per can, 200 cans in total. Seal the mouth of the jar and put a la...

Embodiment 2

[0046] Embodiment 2: 10% eugenol and 1% allicin ester composition emulsifiable concentrate B production

[0047] Accurately and quantitatively weigh 106 kilograms of the former medicine of 94% eugenol, and 11.1 kilograms of the former medicine of 90 percent allicin content. Fully mix the two active medicinal liquids in the preparation tank (1).

[0048] Accurately take by weighing 15 kilograms of ascorbic acid again, drop into the deployment tank (1) and fully mix again.

[0049] Add Nongru No. 500: 20 kg, emulsifier 602: 100 kg in another blending tank (2), add 747.9 kg of ethyl acetate after mixing, and fully mix.

[0050] 867.9 kilograms of materials in the blending tank (2) are all moved into the blending tank (1) through the pipeline, and after sealing the mouth of the tank, start the stirrer to stir for 1 hour. Prepare 1000 kilograms of emulsifiable concentrate B product. The content of eugenol in the sample analysis product is 10.01%, and the content of allicin is 0....

Embodiment 3

[0051] Embodiment 3: the production of 30% eugenol and 1% allicin soluble liquid agent C

[0052] Accurately and quantitatively weigh 319.1 kg of 94% eugenol and 100 kg of mother liquor with 10% allicin content. Fully mix the two active medicinal liquids in the preparation tank (1). Accurately take by weighing 15 kilograms of ascorbic acid again, drop into the deployment tank (1) and fully mix again.

[0053] Add Nongru No. 600: 20 kilograms and emulsifier OP-10: 100 kilograms in the blending tank (2), add 445.9 kilograms of ethanol after mixing, and fully mix.

[0054] 565.9 kilograms of materials in the blending tank (2) are all moved into the blending (1) through the pipeline, and after the mouth of the tank is sealed, the stirrer is started to stir for 1 hour. Prepare 1000 kilograms of C soluble liquid product. The content of eugenol in the sampling analysis product is 29.99%, and the allicin content is 1.01%, promptly becomes 31% soluble liquid agent C product, and pro...

Abstract

The invention provides an agent which is prepared by compounding phytochemicals namely eugenol and allicin in the weight ratio of (1:30)-(30:1). The compounded agent can be prepared into soluble liquid, emulsion in water, an emulsifiable solution, suspension, a suspend emulsion formulation and other formulations and is used for controlling diseases such as powdery mildew, botrytis, downy mildew,viral disease, leaf mold, anthracnose, rust disease, fusarium wilt or epidemic disease and the like of plants. The eugenol and allicin compounded agent has an obvious synergistic effect, and is high in bacteriostasis activity, and low in relative using amount; and the compounded agent can be expected to be developed into an environment-friendly, high-efficiency, and low-toxicity agricultural bacteriacide which has high quality.

Description

technical field [0001] The invention relates to a pesticide composition for preventing and controlling diseases such as powdery mildew, gray mold, downy mildew, viral disease, leaf mold, anthracnose, rust, fusarium wilt or blight, and in particular relates to a A compound preparation of plant-derived compound eugenol and plant-derived compound allicin and its application. Background technique [0002] Eugenol, also known as eugenol, has a chemical name of 2-methoxy-4-allylphenol. Eugenol belongs to phenolic compounds, which is easily oxidized into quinone and loses its original biological activity. The antibacterial and antiviral biological activities of this compound have been reported by many patents. Such as Chinese patent (patent number: ZL 200710021725.9) name is eugenol microemulsion, discloses the preparation method and the application of the bactericidal microemulsion of eugenol as active ingredient; The application of phenol in the preparation of pesticides for t...
