Abstract
The invention provides a long-acting insecticidal spray which contains a raw pesticide component A, a solvent component B and a propellant component C, wherein the raw pesticide component A is a pyrethroid compound accounting for 1-20% of the total weight of the spray; the solvent component B accounts for 0.1-50.0% of the total weight of the spray; the pyrethroid compound is selected from any one or a mixture of more than two of all the stereoisomers of 2,3,5,6-tetrafluro-4-methoxymethylbenzyl-3-(2,2-dichloroethylene)2,2-dimethyl cyclopropane carboxylate, or (S)-2-methyl-4-oxo-3-(2-propynyl)-cyclopene-2-enyl(1R)-trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate. The spray provided by the invention is equivalent to mosquito-repellent incense, liquid mosquito-repellent incense and electrocaloric mosquito-repellent incense slices in the aspect of long-time prevention and control, and can be used more conveniently and safely. The invention also provides a method for preventing and controlling sanitary insect pests by spraying trace spray on the surface of a building structure or a home article.
Description
The application is to be the divisional application of the patent application that August 16, application number in 2011 are 201110234325.2, denomination of invention is " a kind of long-acting insecticidal spraying agent and application thereof " applying date.
Technical field
The present invention relates to a kind of insecticide, be specifically related to a kind of long-acting insecticidal spraying agent, and by spraying at fabric structure or household object surface the method that this spray of trace is prevented and treated sanitary insect pest.
Background technology
Conventional household is used the formulation of kill mosquito to have mosquito-repellent incense, vaporizer mosquito liquid, electric mosquito repellent tablet etc., but need in use with fire, electricity consumption, can make insecticidal active compound constantly be dispersed in indoor environment, this patent product only needs simply to press by injection in use.In the time playing identical preventive effect, avoid with fire, electricity consumption, save the energy, use safely and easy to use, meet the theory of the environment friendly agricultural formulation of the energy-saving and environmental protecting of promotion.
Common aerosol only need to be pressed by injection too, but an about 25m in use
3room in we need to continue to press by spray more than 2 seconds, spray volume is in 8g left and right, in ejection back room, a large amount of solvents are disperseed, after ventilating 4 hours, residual active constituent is difficult to reach preventive effect, and spray of the present invention only need to be pressed by 1 to for several times, metered injection goes out the liquid of 0.1-2g, emitted dose declines more than 4 times, reduce the quantity of solvent in environment, avoid occurring that a large amount of solvents are deposited in desk, the furniture surfaces such as bed, the more important thing is that spray of the present invention can control spray volume, more difficult assurance spray volume how many times can reach preventive effect in use to have avoided common aerosol, spray of the present invention all can reach mosquito-proof effect after ejection in 6～24 hours in addition, do not invaded and harassed by mosquito the time after midnight.Must compare more holding effect, safer, more environmental protection of common aerosol.
In patent documentation CN101637178A, mention and utilizing after aerosol spray, the feature of the minor compound that the pyrethroid compound that vapour pressure is high volatilizes at normal temperatures, reach the situation that continues preventive effect, after through test of many times, find that some vapour pressures are not high, although the active high pyrethroid compound quantity not sufficient that space volatilizes again after injection is to reach preventive effect, but only need this micro-class high activity pyrethroid compound to disperse and be adsorbed on body surface, when mosquito has a rest while dropping on the body surface that contains these high activity pyrethroid compounds, can reach preventive effect.Because active ingredient sticks to body surface and this compounds does not have normal temperature volatility in spray of the present invention, under airtight or ventilation condition, loss ratio is relatively little, causes efficiency time longer, and still has good preventive effect under ventilation state.
