ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an arthropod-controlling composition.
BACKGROUND OF THE INVENTION
Many arthropod-controlling compositions are on the market at present. However, the objected harmful arthropods have many kinds and the situations for controlling them are in many ways. Therefore, the arthropod-controlling composition having practically high effectiveness and safety is desired.
Though pyrethroid insecticides having rapid knock-down efficacy are excellent agents for controlling harmful arthropods, progress of pyrethroid resistance to some arthropods has been reported in various places recently. Under these circumstances, non-pyrethroid compounds having excellent knock-down efficacy are earnestly desired.
On the other hand, it is known that some &agr;-pyrone compounds are effective for controlling harmful acarina and houseflies in Japanese Unexamined Patent Publication No. sho-51-19126. However, the compounds described in the publication do not necessarily give a sufficient effect.
SUMMARY OF THE INVENTION
The present invention provides 4-hydroxy-6-methyl-3-(3-methylbutanoyl)-2-pyrone shown by the formula:
an arthropod-controlling composition comprising it as an active ingredient and a method for controlling arthropods by using it.

As The Pyrone Compound, which is an active ingredient of the present controlling agent, gives an efficacy by contacting the objective harmful arthropods including insects and acarina, it is usually to be formulated as described below for use.
Namely, The Pyrone Compound or its solution can be formulated to the present controlling agent such as oil solution, emulsifiable concentrate, wettable powder, flowable (aqueous suspension or aqueous emulsion), granule, dust and so on, by mixing with solid carrier, liquid carrier or liquefied gaseous carrier and optionally surfactant, the other formulation auxiliaries.
The present controlling agent described above contains usually 0.001 to 95% by weight of The Pyrone Compound as an active ingredient.
Examples of the solid carrier used in the formulation described above include fine granules or granules of inorganic carriers such as clays (e.g. kaolin clay, diatomaceous earth, synthetic hydrated silicon oxide, bentonite, Fubasami clay, acid clay, etc.), talc, ceramics, sericite, quartz, calcium carbonate and so on; synthetic resins such as polyethylene, polypropylene and so on; and carriers originated from plants such as wood powder, activated carbon and so on. Examples of the liquid carrier include water, alcohol
