Abstract
本发明公开了一种高含量除虫菊素杀虫剂。按质量分数计，包括除虫菊素49～66.5％和乳化剂5～30％，所述的乳化剂为脂肪醇聚氧乙烯醚、壬基酚聚氧乙烯醚、聚乙二醇双油酸酯、聚乙二醇单油酸酯或烷基酚聚氧乙烯醚，或者脂肪醇聚氧乙烯醚和壬基酚聚氧乙烯醚两者的混合物。本发明的高含量除虫菊素杀虫剂是一种环保型高含量的除虫菊素杀虫剂，具有良好的杀虫效果，市场前景好。该杀虫剂可用于卫生用药，可有效抑制蚊、蝇、臭虫和蟑螂的发生，也可用于农林害虫防治，该药剂还可以用地沟油作添加剂，为地沟油的有效利用提供了一条途径，从而防治地沟油回流到餐桌上。The invention discloses a high-content pyrethrin insecticide. In terms of mass fraction, it includes 49-66.5% of pyrethrins and 5-30% of emulsifiers. The emulsifiers are fatty alcohol polyoxyethylene ether, nonylphenol polyoxyethylene ether, polyethylene glycol dioleate, Polyethylene glycol monooleate or alkylphenol ethoxylates, or a mixture of fatty alcohol ethoxylates and nonylphenol ethoxylates. The high-content pyrethrin insecticide of the present invention is an environment-friendly high-content pyrethrin insecticide, has good insecticidal effect, and has a good market prospect. The insecticide can be used in sanitary medicine, can effectively suppress the occurrence of mosquitoes, flies, bedbugs and cockroaches, and can also be used in the control of agricultural and forestry pests. The medicament can also use waste oil as an additive, providing a way for the effective use of waste oil. Thereby preventing gutter oil from returning to the dining table.
Description
技术领域：Technical field:
本发明属于新农药开发和应用领域和环保领域，具体涉及一种高含量除虫菊素杀虫剂。The invention belongs to the field of development and application of new pesticides and the field of environmental protection, and in particular relates to a high-content pyrethrin insecticide.
背景技术：Background technique:
除虫菊(PyrethrumcinerariaefoliumTrey)是一种古老的杀虫植物，目前在世界上广泛应用，是三大杀虫植物之一。除虫菊中的杀虫性物质叫除虫菊素，对昆虫的击倒或杀死作用迅速；是一种广谱杀虫剂，可用于农、林、卫生害虫防治，如蚜虫、蓟马、白粉虱、果蝇、甲虫、夜蛾、棉铃虫等多种鳞翅目幼虫都有很好的防治效果，且对蚊、蝇、臭虫和蟑螂效果明显。毒理测定结果表明除虫菊对人和哺乳动物的毒性极低，没有致畸、致癌、致突变的慢性毒性，也不能在哺乳动物体内蓄积残留，是一种安全有效的植物源农药，也是无公害蔬菜生产的理想杀虫剂。Pyrethrum cineraria efolium Trey is an ancient insecticidal plant, which is widely used in the world and is one of the three major insecticidal plants. The insecticidal substance in pyrethrum is called pyrethrin, which knocks down or kills insects quickly; it is a broad-spectrum insecticide, which can be used for agricultural, forestry, and sanitary pest control, such as aphids, thrips, whitefly, Fruit flies, beetles, noctuids, cotton bollworms and other Lepidoptera larvae have very good control effects, and the effect on mosquitoes, flies, bedbugs and cockroaches is obvious. Toxicological test results show that pyrethrum has extremely low toxicity to humans and mammals, has no chronic toxicity of teratogenicity, carcinogenicity, and mutagenesis, and cannot accumulate residues in mammals. It is a safe and effective plant-derived pesticide, and it is also pollution-free. Ideal insecticide for vegetable production.
该药剂在自然环境中不稳定，容易迅速分解为水和二氧化碳，虽然不残留任何有毒物质，不污染环境，但是也影响其效果的。The agent is unstable in the natural environment, and it is easy to quickly decompose into water and carbon dioxide. Although it does not leave any toxic substances and does not pollute the environment, it also affects its effect.
该药剂目前含量较低，据中国农药信息网上公告最高含量为5％乳油和3％的可溶性液剂，检索专利也没有高含量除虫菊素产品和技术。The current content of the medicament is relatively low. According to the China Pesticide Information Online announcement, the highest content is 5% emulsifiable concentrate and 3% soluble liquid, and there is no high-content pyrethrin product and technology in the search patent.
发明内容：Invention content:
本发明的目的是提供一种环保、稳定和高效的高含量除虫菊素杀虫剂。The object of the present invention is to provide an environment-friendly, stable and efficient high-content pyrethrin insecticide.
本发明的高含量除虫菊素杀虫剂，其特征在于，按质量分数计，包括除虫菊素49～66.5％和乳化剂5～30％，所述的乳化剂为脂肪醇聚氧乙烯醚、壬基酚聚氧乙烯醚、聚乙二醇双油酸酯、聚乙二醇单油酸酯或烷基酚聚氧乙烯醚，或者脂肪醇聚氧乙烯醚和壬基酚聚氧乙烯醚两者的混合物。The high-content pyrethrin insecticide of the present invention is characterized in that, in terms of mass fraction, it includes 49-66.5% of pyrethrins and 5-30% of emulsifiers, and the emulsifiers are fatty alcohol polyoxyethylene ether, nonyl Phenol ethoxylates, polyethylene glycol dioleate, polyethylene glycol monooleate, or alkylphenol ethoxylates, or both fatty alcohol ethoxylates and nonylphenol ethoxylates mixture.
