Problems solved by technology

Although oil-based formulas are the mainstream of liquid mosquito-repellent incense so far in the world, water-based formulas can reduce the danger to fireworks compared with oil-based formulas. In addition, compared with oil-based formulas, the insecticidal effect on pests can be said to be The demand for water-based formulations is expected to increase in the future

Embodiment 1

[0065]

[0066] 0.9% by mass of transfluthrin as a pyrethroid-based insecticidal component, 40% by mass of 1,2-hexanediol as a diol-based compound as an insecticidal efficacy enhancer, and 3-methanol as an aqueous organic compound 10% by mass of oxy-3-methylbutanol (SOLFIT), 0.1% by mass of dibutylhydroxytoluene (BHT) as a stabilizer, and 49% by mass of purified water were used to prepare a heat-evaporating water-based insecticide composition.

[0067]

[0068] Contains 52% by mass of mica powder as an inorganic powder, 33% by mass of clay powder as an inorganic binder, 10% by mass of graphite as an organic substance, and 3% by mass of carboxymethylcellulose as an organic binder. , starch 2 mass % mixture, adding water and kneading, extruding while pressurizing the kneading thing, air-dried and then firing at 1100°C to obtain a liquid-absorbing core for heating and transpiration (a round rod with a diameter of 7mm and a length of 66mm) ).

Embodiment 2～16、 comparative example 1～6

[0074] According to Example 1, the water-based insecticide composition for heating and evapotranspiration and the liquid-absorbing wick for heating and evapotranspiration were prepared, and they were loaded in a heating and evapotranspiration device to produce the pest control products of Examples 2 to 16. However, the measurement and test of (1)-(3) mentioned later were implemented about each pest control product of Examples 2-15. Moreover, the measurement and test similar to Example were implemented about the pest control products of Comparative Examples 1-6 produced for comparison. The formulation of the water-based insecticide composition for heating and transpiration and the compounding of the liquid-absorbent wick for heating and transpiration are shown in Tables 1-2 in each Example and Comparative Example separately. In addition, Table 1 also describes the formulation of the water-based insecticide composition for heating and transpiration of Example 1, and the compound...

Abstract

Provided is an insecticidal efficacy enhancer that can effectively enhance the insecticidal efficacy of a pyrethroid insecticide component having a relatively high vapor pressure in an aqueous insecticide composition for thermal transpiration that contains the pyrethroid insecticide component. The insecticidal efficacy enhancer contains, as an active ingredient, a glycol-based compound in which a hydroxyl group is bonded to each of two adjacent carbon atoms in an alkane having 4-7 carbon atoms. The insecticidal efficacy enhancer is blended in an aqueous insecticide composition for thermal transpiration that contains a pyrethroid insecticide component having a vapor pressure of 2*10<-4> to 1*10<-2> mm Hg at 30 DEG C.

Description

technical field [0001] The present invention relates to an insecticidal effect enhancer compounded in a heating transpiration water-based insecticide composition containing a pyrethroid insecticidal component with a high relative vapor pressure, and a heating transpiration water-based insecticide compounded with the insecticidal effect enhancer. A pest control method of an insecticide composition and a heat-evaporating water-based insecticide composition containing the insecticidal effect enhancer. Background technique [0002] As a flying pest control product for controlling flying pests such as mosquitoes, a liquid-absorbent core is soaked in a chemical liquid containing an insecticidal component, and the absorbed chemical liquid is guided to the upper part of the liquid-absorbent core, and the liquid-absorbent core is treated So-called "liquid type mosquito coils" that use heat to evaporate insecticidal ingredients into the atmosphere are already on the market. The insec...
