Embodiment 1

[0026] The high-content pyrethrin insecticide of this embodiment, based on the total mass fraction of 100%, includes 95% of the original drug of pyrethrins and 5% of fatty alcohol polyoxyethylene ether, the content of the active ingredient pyrethrins 70%, the others are fatty acids and a small amount of water. At normal temperature and pressure, fatty alcohol polyoxyethylene ether was added to the pyrethrin raw drug, stirred and mixed uniformly to form a 66.5% pyrethrin emulsion, and the high-content pyrethrin insecticide of this example was obtained. Dilute 12,000 times of water for the control of citrus red spiders, the control effect is more than 95%; it is used for the maintenance of family flowers and trees, and has a good control effect on scale insects, thrips and whitefly.

Embodiment 2

[0028] The high-content pyrethrin insecticide of this embodiment, based on the total mass fraction of 100%, includes 90% of the original pyrethrin and 10% of the fatty alcohol polyoxyethylene ether. The content of the pyrethrin in the active ingredient is 70%, the others are fatty acids and a small amount of water. Under normal temperature and pressure, fatty alcohol polyoxyethylene ether was added to the pyrethrin raw drug, stirred and mixed uniformly to form a 63% pyrethrin emulsion, and the high-content pyrethrin insecticide of this example was obtained. Dilute 12,000 times of water for the control of citrus red spiders, the control effect is more than 95%; it is used for the maintenance of family flowers and trees, and has a good control effect on scale insects, thrips and whitefly.

Embodiment 3

[0030] The high-content pyrethrin insecticide of this embodiment, based on the total mass fraction of 100%, includes 80% of the original pyrethrin and 20% of the fatty alcohol polyoxyethylene ether. The content of the active ingredient pyrethrin in the described pyrethrin 70%, the others are fatty acids and a small amount of water. Under normal temperature and pressure, fatty alcohol polyoxyethylene ether was added to the pyrethrin raw drug, stirred and mixed uniformly to form a 56% pyrethrin emulsion, and the high-content pyrethrin insecticide of this example was obtained. Dilute 10,000 times of water for the control of citrus spider mite, the control effect is more than 95%; it is used for the maintenance of family flowers and trees, and has a good control effect on scale insects, thrips and whitefly.

Abstract

The invention discloses an insecticide with high-content pyrethrin. The insecticide comprises, in percentage by mass, 49%-66.5% of pyrethrin and 5%-30% of an emulsifier, wherein the emulsifier adopts fatty alcohol-polyoxyethylene ether, polyoxyethylene nonyl phenyl ether, polyethylene glycol dioleate, polyethylene glycol monooleate or alkyl phenol polyoxyethyleneether or a mixture of fatty alcohol-polyoxyethylene ether and polyoxyethylene nonyl phenyl ether. The insecticide with the high-content pyrethrin is environment-friendly, has a good insect-killing effect and good market prospect, can be used for hygienic application, can effectively prevent mosquitos, flies, bugs and cockroaches and can also be used for agricultural and forest pest control; swill-cooked dirty oil can be used as an additive of the insecticide, an approach is provided for effective use of the swill-cooked dirty oil, and reuse of the swill-cooked dirty oil for cooking can be controlled.

Description

Technical field: [0001] 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. Background technique: [0002] 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,...
