ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a composition for the extermination of harmful arthropods.
BACKGROUND OF THE INVENTION
Various types of agents for the extermination of harmful arthropods have been used so far. In some cases of application, however, it cannot be said that they exhibit satisfactory effects.
SUMMARY OF THE INVENTION
Under these circumstances, the present inventors have extensively studied many compositions for the extermination of harmful arthropods. As a result, they have found that the combined use of at least one compound selected from 1-(tetrahydrofuran-3-yl)methyl-3-methyl-2-nitroguanidine and 3-[(2-chloro-5-thiazolyl)methyl]-5-methyl-4-nitroiminotetrahydro-1,3,5-oxa-diazine with pyriproxyfen makes it possible to exhibit remarkable synergism and therefore gives excellent extermination effects against various harmful arthropods by their application in smaller amounts, thereby completing the present invention.
Thus, the present invention provides a composition for the extermination of harmful arthropods (hereinafter referred to as the present composition), characterized in that it comprises at least one compound (hereinafter referred to as the nitroimino compound) selected from 1-(tetrahydrofuran-3-yl)methyl-3-methyl-2-nitroguanidine and 3-[(2-chloro-5-thiazolyl)methyl]-5-methyl-4-nitroiminotetrahydro-1, 3,5-oxadiazine, and pyriproxyfen, as active ingredients.
DETAILED DESCRIPTION OF THE INVENTION
The nitroimino compound used in the present invention is known to have control activity against various pests in the field of agriculture and disclosed in U.S. Pat. Nos. 5,532,365 and 5,852,012. On the other hand, pyriproxyfen is a compound commercially available as the active ingredient of pesticides for domestic prevention of epidemics and for agriculture.
The mixing ratio of nitroimino compound to pyriproxyfen used in the present composition as expressed by the “nitroimino compound/pyriproxyfen (weight ratio)” is usually not higher than 1000/1, preferably not higher than 100/1, and more preferably not higher than 10/1, but usually not lower than 1/10, preferably not lower than 1/5, and more preferably not lower than 1/1. That is, the mixing ratio of nitroimino compound to pyriproxyfen is generally in the range of from 1000:1 to 1:10, preferably from 100:1 to 1:10.
