Abstract
The present invention discloses a Yanshensu emulsion pesticide and a preparing method thereof. The pesticide is composed of the effective components of the extracting solutions of tobacco leaf, lightyellow sophora root, stemona root and Chinese honeylocust fruit. The extracting solution accounts for 40 to 50% of the pesticide, ethanol accounts for 18 to 25%, and an auxiliary agent accounts for 30 to 40%. The preparing method comprises: processing the materials of the proportion by weight of 50 to 60% of tobacco leaf, 15 to 20% of lightyellow sophora root, 15 to 20% of stemona root and 5 to 10% of Chinese honeylocust fruit through slicing, washing, soaking and decocting for 100 to 120 minutes, extracting a medicinal solution, and then processing the medicinal solution through sedimentation, centrifugation, filtration and condensation to obtain a prepared mother solution; adding the ethanol to the mother solution, and then standing for 8 hours; adding a penetrating agent, an emulsifying agent and a synergistic agent, and then obtaining finished products after 8 hours. Field experiments and animal experiments show that the pesticide has the advantages of high efficiency, broad spectrum, low toxicity and no damage to people and livestock.
Description
The present invention relates to a kind of insecticide that extracts from plant, is the alkaloid insecticide specifically.At present agricultural goes up a large amount of chemical insecticides such as organic phosphor that use, and residual life is longer, to people and animals' high toxicity, people and animals' health is had bigger harm.
The object of the present invention is to provide the novel plant insecticide of a kind of efficient, wide spectrum, little poison, use this insecticide good disinsection effect, again to the person poultry harmless.
Technical scheme of the present invention is as follows:
Yansensu emulsion is to have to tag and the insecticide of stomach poison function, and its effective ingredient is made up of the extract at tobacco leaf, radix sophorae, RADIX STEMONAE, Chinese honey locust angle, and this extract accounts for the 40--50% of insecticide, and it mainly contains effective constituent and is:
A: nicotine (NICOTINE), its structural formula is:
Molecular formula is: C
10H
14N
2, molecular weight is: 162.24
B: matrine (MATRINE) and oxymatrine (OXYMATRINE), its structural formula is respectively:
The content of nicotine is 0.7--1.5% in the Yansensu emulsion, and the content of matrine and oxymatrine is 0.5--1.0%;
This Yansensu emulsion also contains organic solvent ethanol 18--25%;
This Yansensu emulsion also contains the auxiliary agent of 30--40%, and they are bleeding agent, emulsifier, synergist.
The ratio of the auxiliary agent of this Yansensu emulsion is a bleeding agent: emulsifier: synergist=2.5: 1: 0.5.
Yansensu emulsion is dark brown liquid, and its low temperature and heat storage are all stablized, and deposit 7 days no solids, no separator at 0 ± 2 ℃; Deposited 14 days at 54 ± 2 ℃, do not have precipitation, no layering.
The preparation method of this Yansensu emulsion comprises the steps: 1, be tobacco leaf 50--60% with weight ratio, kuh-seng 15--20%, tuber of stemona 15--20%, Chinese honey locust 5--10% cuts into slices, and puts into to boil in the jar to decoct after washing, immersion, pick up counting from boiling, boiled 100--120 minute, with admixing medical solutions propose through precipitation, centrifugal, filter and become clear liquid, again clear liquid is carried out vacuum concentration, temperature is at 70--80 ℃, and being concentrated into Baume degrees becomes the preparation mother liquor for 30 °;
2. add ethanol in mother liquor, the limit edged stirs, and mother liquor is 2: 1 with the ratio of ethanol, and mixed liquor was left standstill 8 hours, becomes the mixing clear liquid;
3. will mix the clear liquid adding assistant, add 30--35 ℃ of auxiliary agent, be finished product after in the time of 8 in the ratio of the 30--40% that accounts for this emulsion total amount.
The invention has the advantages that: 1, efficient, wide spectrum, the term of validity are long, through two province's two places field trials, see Table one.Mythimna separata, cabbage caterpillar, pear sucker, aphid, two spotted spider mite, broccoli diamond-back moth all had tag and stomach poison function, the preventive effect of mythimna separata, cabbage caterpillar, aphid, broccoli diamond-back moth is better than the existing chemical insecticide of using, control rate is 73--100%.2, owing to Chinese honey locust is arranged than thickness in the extract, it is good to spray application on the blade tack, because that the adding assistant quick permeation is tagged this insecticide is effective.3, little poisons Tianjin labour health occupation disease precaution﹠china institution measures, its method is: the stomach that pours into big white mouse with this insecticide per os, observe its poisoning and death condition in two weeks, calculate its lethal dose LD＞5000mg/kg with hat for method, according to chemical substance acute toxicity standard, this agricultural chemicals is little poison.4. people and animals are not had the chromosome aberration of causing, embryo's distortion, cell produces the harm of micronucleus.(1) do small white mouse bone marrow stain body distortion analysis with this insecticide 1000mg/kg and 10000mg/kg two dosage, the medicine per os is irritated stomach, puts to death the back and observes its chromosome, and its result is negative; (2). this insecticide makes teratology testing for the same method administration of pregnant mouse with the dosage of 1000mg/kg, and its result is negative; (3). this insecticide with the same method administration, makes to produce micronucleus test with the dosage of 1000mg/kg and 5000mg/kg, and two kinds of dosage mouse of its result perilymphatic cell micronucleus is checked negative.5, cost is low, and this insecticide cost is lower than similar import agricultural chemicals.
