Problems solved by technology

The long-term use of these single agents has caused sanitary pests such as mosquitoes, flies, cockroaches, etc. to produce varying degrees of resistance to some pyrethroids, and the control effect is greatly reduced.
At the same time, some space sprays contain more organic solvents, which can easily lead to strong odor and environmental pollution when used, and users may even fall down due to the large amount of solvents on the ground and cause injuries. However, if there is no large solvent in actual use, the prevention effect will decrease. , mainly because the presence of solvents can improve the volatilization and penetration properties of drugs

Abstract

The invention provides a compounded insecticidal aqueous emulsion. The compounded insecticidal aqueous emulsion comprises 2-15wt% of an insecticidal active component, 5-15wt% of a cosolvent, 3-15wt% of an emulsifier, 1-10wt% of an antifreeze agent, 0.1-0.5wt% of an antifoaming agent, and the balance of water; the insecticidal active component is composed of permethrin and tetramethylfluthrin according to a weight ratio of 1:20-30:1; and the cosolvent is selected from one or a mixture containing two or more of piperonyl butoxide, N-methylpyrrolidone, odorless kerosene, trimethylbenzene, tetramethylbenzene and pentamethylbenzene. The above insecticide is an aqueous emulsion obtained by compounding permethrin and tetramethylfluthrin and by processing, so the aqueous emulsion reduces the use of an organic solvent and is environmentally friendly; and tetramethylfluthrin has an extremely good knockdown effect on health pests, and permethrin has a fatal effect, so the aqueous emulsion has substantial synergistic effects on outside environment control of the health pests, reduces the application amount of drugs, and delays the drug resistance of the pests.

Description

technical field [0001] The invention relates to an insecticide, in particular to a compound pesticide insecticidal emulsion in water containing permethrin and transfluthrin, and an application thereof. Background technique [0002] For a long time, most of the space sprays used for public health pests are permethrin single agents. For example, the current WHO is still promoting ultra-low volume sprays of permethrin for the prevention and control of adult mosquitoes in public environments. The long-term use of these single agents has caused sanitary pests such as mosquitoes, flies, cockroaches, etc. to produce drug resistance to some pyrethroids in varying degrees, and the control effect is greatly reduced. At the same time, some space sprays contain more organic solvents, which can easily lead to strong odor and environmental pollution when used, and users may even fall down due to the large amount of solvents on the ground and cause injuries. However, if there is no large s...
