Problems solved by technology

Since pyrethroid agents have an excellent knockdown effect on public health pests, if we want to consider pest resistance, we can start with lethal agents; in addition, some space sprays are generally emulsifiable concentrates, which contain more organic solvents. It is easy to pollute the environment and is not friendly enough to the applicators

example 1

[0023] Dissolve 1% dinotefuran and 15% perfluthrin in 7% dimethyl sulfoxide and 3% piperonyl butoxide, then add 5% castor oil polyoxyethylene ether and 3% alkyl Calcium benzenesulfonate, fully stirred, sheared with a high-speed shear emulsifier, added 8% ethylene glycol, 0.2% organic silicon defoamer in the shearing process, supplemented deionized water to 100%, and finally obtained 16 % dinotefuran · tetrafluthrin aqueous emulsion.

example 2

[0025] Dissolve 1.5% dinotefuran and 15% perfluthrin in 10% N-methylpyrrolidone solvent, then add 4% styrylphenol polyoxyethylene ether and 3% fatty alcohol polyoxyethylene ether , 3% Tween-80, fully stirred, sheared with a high-speed shear emulsifier, added 5% propylene glycol, 0.3% C8-10 fatty alcohol compounds during the shearing process, and supplemented deionized water to 100% , and finally obtained 16.5% dinotefuran·tefluthrin aqueous emulsion.

example 3

[0027] Dissolve 3% dinotefuran and 15% perfluthrin in 4% dimethyl sulfoxide and 6% cyclohexanone, then add 4% nonylphenol polyoxyethyl ether, 2% Phenylphenol polyoxyethyl ether phosphate, 5% alkyl aryl polyoxyethylene polyoxyethyl ether, stir fully, shear with a high-speed shear emulsifier, add 10% propylene glycol during the shearing process , 0.4% of C10-20 saturated fatty acid compounds, supplemented with deionized water to 100%, and finally obtained 18% dinotefuran·tefluthrin aqueous emulsion.

Abstract

The invention discloses a dinotefuran-containing compound insecticidal composition and application thereof, wherein active ingredients comprise dinotefuran and tetramethylfluthrin or transfluthrin, the weight ratio of dinotefuran to tetramethylfluthrin is (1:15)-(15:1), preferably (1:4)-(8:1), and the weight ratio of dinotefuran to transfluthrin is (1:15)-(15:1), preferably (1:3)-(8:1). According to the insecticide, dinotefuran and tetramethylfluthrin or transfluthrin are compounded and processed into emulsion in water or microemulsion, so that use of organic solvents is reduced, and the insecticide is more environmentally friendly, wherein tetramethylfluthrin or transfluthrin has an excellent knockdown property on public health pests such as mosquitoes, flies and the like, and due to the lethal effect of dinotefuran, the bactericidal composition has a remarkable synergistic effect on prevention and treatment of public health pests, the application amount of the pesticide can be reduced, the cost is saved, and the drug resistance of the pests is delayed.

Description

technical field [0001] The invention relates to an insecticide, in particular to a compound pesticide insecticide containing dinotefuran and transfluthrin or transfluthrin. Background technique [0002] As we all know, most of the space spraying agents used for public health pests are pyrethroid preparations. The long-term use of these agents will inevitably make hygienic pests such as mosquitoes, flies, cockroaches, etc. resistant to some pyrethroid agents. The control effect will be greatly reduced. Since pyrethroid agents have an excellent knockdown effect on public health pests, if we want to consider pest resistance, we can start with lethal agents; in addition, some space sprays are generally emulsifiable concentrates, which contain more organic solvents. It is easy to pollute the environment more, and it is not friendly enough to the applicators. Therefore, we consider developing a non-pyrethrin compound insecticide for space spraying to control public health pests....
