Room-temperature volatile insecticidal spray composition and application thereof

Abstract

The invention relates to a room-temperature volatile insecticidal spray composition and application thereof. According to the insecticidal spray, the characteristics of high basic activity and high room-temperature volatility of dimefluthrin, transfluthrin, tetramethylfluthrin, meperfluthrin, heptafluthrin and metofluthrin are fully utilized; a low-toxicity and environment-friendly volatilizationaccelerator with the volatilization speed of 300 to 3000 is used; a volatilization auxiliary carrier solvent with a volatilization speed of 20-300 is used as an auxiliary material; the volatilizationaccelerator and the auxiliary material are mixed according to a specific ratio; a conventional spraying device is adopted; after micron-sized effective component fog drops are sprayed into an indoor environment, the solvent is rapidly volatilized, the fog drops are rapidly refined, on one hand, a faster quick-acting insecticidal effect is achieved, and on the other hand, the effective component fog drops are permanently suspended and fully dispersed, so that the effective component fog drops are more uniformly dispersed and attached to the surface of a building structure or a household object,and a more stable long-acting volatilization insecticidal effect is achieved.

Description

technical field [0001] The invention relates to the field of hygienic insecticides, in particular to hygienic insecticide formulations, in particular to a normal temperature volatile insecticide spray composition and its application. Background technique [0002] Generally speaking, the use of insecticide sprays to prevent and control sanitary pests can only have a good killing effect on those pests that are in direct contact with the pesticides within a relatively short period of time when the pesticides are sprayed. For indoor flying pests, electric heating devices are needed to continuously disperse the insecticidal active ingredients in the indoor environment.

The aerosol can realize the slow release of the drug effect, and can still maintain the control effect on mosquitoes within 6-10 hours; while the insecticidal sprays described in the above patents all use the propellant liquefied petroleum gas propylene butane to make the aerosol However, propane-butane itself has the characteristics of flammability and explosion, and there are certain potential safety hazards, and the compressed gas volatilizes too fast, which is difficult to drive the initial release and dispersion of active ingredients; and it is unstable during transportation, and transportation costs are relatively high. high

[0004] Our research found that the perflumethrin, transfluthrin, transfluthrin, bichlorofluthrin, seflumethrin, and metfluthrin in the pyrethroids All have the characteristics of high basic activity and good volatilization effect at room temperature. Although these traditional hygienic insecticide formulations such as mosquito coils, aerosols, quantitative aerosols, electric mosquito coils, and electric mosquito coils can play a better role in killing However, mosquito coils need to burn a large amount of base materials to pollute the indoor environment; aerosols or quantitative aerosols use compressed liquefied petroleum gas, which is inconvenient to transport and carry, and there are a lot of organic solvent residues; dosage forms such as electric mosquito coils and electric mosquito coils An electric heating device is also required, and a large amount of non-volatile organic solvents are heated into the indoor environment, which has certain inconvenience and use limitations
