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 compound insecticidal composition containing dinotefuran and its application. The weight ratio of esters is 1:15-15:1, preferably 1:4-8:1; the weight ratio of dinotefuran and transfluthrin is 1:15-15:1, preferably 1:3-8: 1. The insecticide described in the present invention is processed into aqueous emulsion or microemulsion by compounding dinotefuran and transfluthrin or transfluthrin, which reduces the use of organic solvents and is more friendly to the environment. Biflufenthrin or transfluthrin has excellent knockdown properties against mosquitoes, flies and other public health pests, and the lethal effect of dinotefuran has a significant synergistic effect in the prevention and control of public health pests, which can reduce the amount of pesticides Reduce the amount of application, save costs, and delay the emergence of pest resistance.

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....
