Pesticide spray

Abstract

The invention provides a pesticide spray for quantitatively jetting. The effective ingredient of mist spray comprises an active compound component A, a solvent component B and a propellant component C, wherein the effective ingredient of the mist spray comprises greater than or equal to 0.05wt% and smaller than 0.5wt% of the components A, 0-70.0wt% of the solvent component B and 29.45-99.45wt% of the propellant component C; and the active compound component A is pyrethroid compound, and is selected from one or mixture of more than two of metofluthrin, dimefluthrin, teflon ethofenprox, right anti-propargyl chloride propiolic fenvalerate, cyfluthrin, efficient cyfluthrin, deltamethrin, lambda-cyhalothrin, cyphenothrin, d-cyphenothrin and fine d-cyphenothrin. The pesticide spray for quantitatively jetting utilizes a quantitative nozzle device of which the discharge rate is 0.05-1ml for each time. The pesticide spray for quantitatively jetting disclosed by the invention can achieve the purpose of effectively helping more uniform distribution of the active compound within spaces with different sizes, and is more favorable to the environment and health of a human body at the same time.

Description

technical field [0001] The invention relates to an insecticidal spray, which can be sprayed twice or more through a quantitative spray device, so that the medicine is more dispersed and uniform, the efficacy of the medicine is improved, the amount of the original medicine and the content of the preparation are reduced, and finally it can effectively prevent and treat insecticides. Methods of sanitation from pests. Background technique [0002] In the prior art, perfluthrin and mefluthrin developed by Sumitomo Chemical have been reported to have insecticidal activity; perfluthrin, D-trans permethrin, cyfluthrin, Beta-cyfluthrin (Baishu), deltamethrin, beta-cyhalothrin (Kung Fu), cyphenothrin, d-cyphenothrin, and refined d-cyfluthrin are also commercialized pesticides. Insecticide. There are very early literature reports on the application of perfluthrin and d-trans-permethrin in conventional insecticide aerosols. When used in accordance with the national standard GB13917. ...

Problems solved by technology

[0003] On the other hand, we have conducted research in CN102308842A, disclosing a quantitative spray formulation with 0.5-20% active ingredient content such as cyfluthrin, but in the above-mentioned documents, our research is not thorough enough, and we have not been able to use the formulation The lower limit of the concentration was determined, and it did not take into account how to control the dosage more accurately when used in a small space to prevent drug damage. During further research, it was found that when the concentration of the active ingredient of permethrin was high, a large dose was sprayed once. It is easy to cause the original drug to disperse unevenly and the local concentration is high. Whether it is the effective dose of the mosquito, or the use of the compound to volatilize into the space to achieve the prevention effect, this high local concentration will lead to the need to use more original drug. reach prevention effect

Moreover, due to the limitation of the precision and cost of the existing technology in mechanical processing, the volume of the quantitative nozzle cannot be processed very small. Generally, 0.05ml is the limit. If you want to control the dose of a spray, the better way is to reduce the active ingredient. Concentration of use

When using the high concentration product in CN102349536A, if 28m 3 The room can be used once, if only 14m 3 In a room or a smaller space, if you can’t spray half a time or less, you can only spray once, and the extra part will cause waste, and the amount of medicine in the unit space will increase, which is unhealthy for people and prone to injury.
