The present invention will be described in more detail below with reference to formulation examples and test examples, but the present invention is not limited to these examples.

First, formulation examples will be shown. In addition, a part represents a weight part. Formulation Example 1 5 parts of compound (A), 5 parts of compound (B), 8 parts of polyoxyethylene styryl phenyl ether, 2 parts of calcium dodecylbenzenesulfonate and 80 parts of xylene are uniformly mixed to obtain an emulsion.

Formulation Example 2 0.5 part of compound (A), 1 part of compound (B), talc 4
8.5 parts and 50 parts of clay are uniformly mixed and pulverized to obtain a dust.

Formulation Example 3 To 10 parts of compound (A) and 5 parts of compound (B), 5 parts of sodium dodecylbenzenesulfonate, 30 parts of bentonite and 50 parts of clay are added, and they are sufficiently stirred and mixed. Then
An appropriate amount of water is added to these mixtures, and the mixture is further stirred, granulated by a granulator, and air-dried to obtain granules.

Formulation Example 4 5 parts of polyoxyethylene styryl phenyl ether sulphate, 20 parts of a 1% xanthan gum aqueous solution, 3 parts of smectite minerals and 57 parts of water were uniformly dissolved to obtain 5 parts of compound (A) and 10 parts of compound (B). After adding parts and stirring well, wet milling is carried out with a sand mill to obtain a flowable agent.

Formulation Example 5 0.02 parts of compound (A) and 0.1 part of compound (B) were dissolved in 10 parts of acetone, and this solution was mixed with solid feed powder for animals (solid feed powder for breeding and breeding CE- 2: Uniformly mixed with 99.88 parts of Nippon Claire Co., Ltd.), and then air-dried with acetone to obtain a poison bait.

Next, the test examples show that the composition of the present invention is useful as a pest control agent. Test Example 10 parts of compound (A), 35 parts of white carbon containing 50 parts of polyoxyethylene alkyl ether sulfate ammonium salt and 55 parts of water were mixed and finely pulverized by a wet pulverization method to obtain a preparation of compound (A). It was A water-diluted solution of this formulation of compound (A) at a predetermined concentration and compound (B)
10% flowable agent (trade name: Kotetsu Flowable, manufactured by Kumiai Chemical Industry Co., Ltd.) was mixed with a diluted solution of water having a predetermined concentration to prepare a test chemical solution. 2 ml of the above test chemical solution was added dropwise to an artificial feed (Insector LF (manufactured by Nippon Nosan Kogyo Co., Ltd.) cut to a weight of 18 g). Fifteen fourth instar larvae of Spodoptera litura were released here, and the life and death of the test insects were observed 4 days later. From the results, the mortality rate was calculated by the following formula. Mortality rate = {Number of dead insects / (Number of surviving insects + Number of dead insects)} × 100 The results are shown in Table 1.
