Embodiment 1

[0034] 1 The acquisition of cytisine extract

[0035] Firstly, lanceolata chinensis is crushed through a 60-mesh sieve with a pulverizer, and then the raw material powder is soaked in ethanol. The soaking parameters are 90% ethanol volume fraction, 10 times the amount of ethanol, at room temperature, for 24 hours. 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.

[0036] 2 Obtaining of matrine extract

[0037] First, crush the Sophora sophora, pass through a 60-mesh sieve, then dissolve the raw material powder with 15 times the ethanol with a volume fraction of 70%, and then reflux extraction at 70°C for 1.5 hours to obtain the extract. Equivalent to 2 grams of crude drug.

[0043] 1 The acquisition of cytisine extract

[0044] Firstly, lanceolate Huanghua was crushed through a 60-mesh sieve with a pulverizer, and then the raw material powder was dissolved in 15 times the ethanol with a volume fraction of 60%, and then extracted with 100 MHz ultrasonic wave for 30 minutes at a temperature of 35 ° C, and then suction filtered. It is obtained after being concentrated by rotary evaporation, and the extract is equivalent to 2 grams of crude drug per 1 milliliter of medicinal solution.

[0045] 2 Obtaining of matrine extract

[0046] First, crush the Sophora sophora, pass through a 60-mesh sieve, and then soak the raw material powder in ethanol. The soaking parameters are 60% ethanol volume fraction, 15 times the amount of ethanol, and 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.

Abstract

The invention relates to cytisine and matrine insecticide water emulsion, which belongs to the water emulsion obtained through compounding 15 to 20 volume percent of gorse cytisine extract liquid with 8 to 10 volume percent of matrine extract liquid, wherein 1ml of medicine liquid of gorse cytisine extract liquid equals to 2g of crude drugs, and 1ml of medicine liquid of matrine extract liquid equals to 2g of crude drugs. The two kinds of plant source alkaloid of the cytisine and the matrine are mixed, so biopesticide with the advantages of high efficiency, low toxicity and little environment pollution is obtained. Major ingredients such as the cytosine and the matrine are natural products extracted from plants, and both the cytisine and the matrine have the insecticidal action, so strong killing effects are realized on pests, the drug resistance is not easy to occur, no harmful chemical pesticide ingredients are contained, the toxicity on people and livestock is low, no residue is left, and the environment is not polluted.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, in particular to a cytisine matrine insecticidal water emulsion. Background technique [0002] China has thousands of years of experience in the application of medicinal plants, a unique theory of traditional Chinese medicine, a traditional theory of Chinese herbal medicine compatibility, and a rich variety of botanical pesticides. Pesticides have been used for many years, and a lot of toxicology and efficacy data have been accumulated, which provides a solid material, theoretical and technical basis for the development of new biopesticides. [0003] The sources of botanical pesticides in China are extremely extensive, and nearly 1,300 kinds of plants have been found to contain insecticidal and bactericidal active substances. Judging from the current research results, the pesticide plants are mainly concentrated in Meliaceae, Asteraceae, Fabaceae, Euonymus, Euphorbiaceae, Lamiaceae...
