Description
Technical field
The present invention relates to a kind of pesticidal preparations, be specifically related to a kind of pesticide spray and application thereof.
Background technology
Publication number is to have mentioned a kind of spray in the patent documentation of CN101637178A, utilize the characteristic of the volatilizable pyrethroid compound of normal temperature, after making to use, by the normal temperature volatile performance of compound itself, in 6～10 hours, still can keep the control efficiency to mosquito.
But we find that this spray is after use between 0～10 hour, in unit hour, the pyrethroid amount of volatilization is relevant with the vapour pressure of compound itself, and be early stage volatile quantity large, later stage volatile quantity is little, this declines later stage control efficiency, after surpassing 10 hours, be difficult to especially reach control efficiency, and after inventor's research, discovery is added after certain slowly-releasing auxiliary element in spray, not only make in 10 hours more constant before and after pyrethroid phase volatile quantity, also make efficiency time extend to 12 hours, guaranteed better by mosquito, not harassed a night.
Summary of the invention
The object of the invention is to: a kind of pesticide spray is provided, and the formulated in combination by four kinds of components forms, can the constant slow release that maintains active compound component A after use, to reach the method for long-term control sanitary insect pest.
