Embodiment 1

[0028] 1 Obtaining the extract of Euphorbia euphorbia

[0029] First, dry the Euphorbia euphorbia in the air, crush it through a 60-mesh sieve, and soak the raw material powder in ethanol. The soaking parameters are 60%-90% ethanol volume fraction, 10-15 times the amount of ethanol, and 12-36 hours at room temperature. Then, it is obtained by suction filtration and concentrated by rotary evaporation, and the extract is equivalent to 2 grams of crude drug per 1 milliliter of medicinal liquid.

[0030] 2 The preparation of milk emulsion Euphorbia plant insecticidal water emulsion

[0031] According to the following volume percentage, the raw materials are uniformly mixed.

[0032] Euphorbia ethanol extract 10%, rotenone 2%, wintergreen oil 10%, turpentine 44%, acetone 24%, emulsifier 10%.

[0033] Wherein the emulsifier is prepared in the ratio of Nongru 500 (calcium dodecylbenzenesulfonate): alkylbenzene=1:1 (volume ratio).

Embodiment 2

[0035] 1 Obtaining the extract of Euphorbia euphorbia

[0036] First, dry the Euphorbia euphorbia in the air, crush it through a 60-mesh sieve, and then dissolve the raw material powder with 10-15 times the ethanol with a volume fraction of 60-90%. Ultrasonic extraction for 30-60 minutes, then suction filtration, concentrated by rotary evaporation, the extract is equivalent to 2 grams of crude drug per 1 ml of medicinal solution.

[0037] 2 The preparation of milk emulsion Euphorbia plant insecticidal water emulsion

[0038] According to the following volume percentage, the raw materials are uniformly mixed.

[0039] Euphorbia ethanol extract 15%, rotenone 3%, wintergreen oil 8%, turpentine 44%, acetone 22%, emulsifier 8%.

[0040] Wherein the emulsifier is prepared in the ratio of Nongru 500 (calcium dodecylbenzenesulfonate): OP-10 (alkylphenol polyoxyethylene ether)=1:1 (volume ratio).

Embodiment 3

[0042] 1 Obtaining the extract of Euphorbia euphorbia

[0043] Firstly, the milky Euphorbia is dried, crushed through a 60-mesh sieve, and then the raw material powder is dissolved in 10 to 15 times the ethanol with a volume fraction of 60% to 90%, and then refluxed at a temperature of 50 to 70°C to extract 1 ~3 hours.

[0044] 2 The preparation of milk emulsion Euphorbia plant insecticidal water emulsion

[0045] According to the following volume percentage, the raw materials are uniformly mixed.

[0046] Euphorbia ethanol extract 12%, rotenone 5%, wintergreen oil 10%, turpentine 40%, acetone 24%, emulsifier 9%.

[0047] Wherein the emulsifier is prepared in the ratio of Nongru 500 (calcium dodecylbenzenesulfonate): OP-10 (alkylphenol polyoxyethylene ether)=1:1 (volume ratio).

Abstract

The invention relates to a euphorbia esula plant pest-killing emulsion in water. The emulsion in water is formed by compounding euphorbia esula ethanol extracting solution and rotenone. According to volume percent, the dosage of the euphorbia esula ethanol extracting solution is 10%-15%, the dosage of rotenone is 2%-5%, and one milliliter of the euphorbia esula ethanol extracting solution is equivalent to 2 grams of crude drugs. The pest-killing plant, euphorbia esula serves as a raw material, pest-killing active ingredients in raw plants are utilized for pest control, a green pesticide is prepared by scientific compounding, a main pest-killing active ingredient of the green pesticide is flavonoid glycoside, and restraining pests is achieved by food refusal and stomach poisoning effects. The euphorbia esula plant pest-killing emulsion in water is mainly used for controlling wolfberry aphid, and the comprehensive control effect can be over 90%.

Description

technical field [0001] The invention belongs to the technical field of biopesticides, and in particular relates to an emulsion euphorbia plant insecticidal aqueous emulsion. Background technique [0002] With the implementation of the sustainable development strategy of human beings, people have gradually begun to pay attention to the direct or indirect potential dangers and hazards caused by the application of toxic chemicals. Therefore, the development of high-efficiency, low-toxic, low-residue, and environmentally compatible pesticides that conform to the concepts of environmental protection, health, and sustainable development has become the subject of current pesticide research. [0003] Milk Euphorbia is a perennial herbaceous poisonous plant of Euphorbiaceae. It is distributed in all major provinces and regions of my country, but it mostly grows in grasslands, hillsides, dry sandy land and roadsides. In Ningxia, it is distributed in Yanchi, Tongxin, Guyuan City and v...
