The present invention relates to stable thermal fumigation pest control compositions, and more particularly to 3-(2-methoxyphenyl)-5-methoxy-1,3,4- as an active ingredient.
A stable thermal fumigation pest control composition containing oxadiazol-2(3H)-one. The above 3-(2-methoxyphenyl)-5-methoxy-1,3,4-oxadiazole-2(3H)
-one (hereinafter referred to as compound A) is known to have high pest control activity [D. Ambrosi et al.
al (1979): Proc.Brit.Prot.Conf, Pests and
Diseases, p. 533], however, it has poor stability, especially thermal stability, and there are various limitations when using Compound A as an insecticide or acaricide. In particular, when Compound A is used in the form of a heating fumigant at a heating temperature of 150 DEG C. to 350 DEG C., its decomposition is so severe that it is virtually impossible to use it. As a result of various studies to enable the use of Compound A as a heat fumigant, the present invention has developed Compound A.
By adding a phenolic compound represented by the following general formula [] and/or sorbitan monooleate, or these and piperonyl butoxide as a stabilizer to the compound A, the stability of compound A is significantly increased, making it difficult to heat fumigation. The present invention was completed based on the discovery that it could be put to practical use as a drug. (In the formula, R 1 and R 2 are the same or different and represent a hydroxyl group or a group -OOC-CH=CH 2 , and R 3 and R 4 are the same or different and represent a methyl group or an ethyl group. However, R 1 and
Either one of R 2 is a hydroxyl group. ) That is, the present invention contains Compound A as an active ingredient, a phenolic compound represented by the above general formula [ ] and/or sorbitan monooleate, or these and piperonyl butoxide as a stabilizer. A stable thermal fumigation pest control composition is provided. The composition of the present invention can be used in the form of heat fumigation without impairing the high insecticidal and acaricidal efficacy of Compound A, and is effective in exterminating various pests such as house flies, mosquitoes, cockroaches, aphids, planthoppers, and mites. Demonstrates outstanding effectiveness. The composition of the present invention will be explained in detail below. Examples of the phenolic compound represented by the following general formula [] used as a stabilizer in the composition of the present invention include the following.

The amount (weight) of the above-mentioned phenolic compound, sorbitan monooleate or piperonyl butoxide used as a stabilizer in the present invention is 1/20 to 2 times the total amount of stabilizer relative to Compound A. Any amount can be used, but preferably from one-tenth to an equivalent amount. The formulations obtained from the composition of the present invention include, for example, making a mosquito coil by kneading the composition of the present invention into a mosquito coil base material and punching it out in the shape of an incense coil, or by applying the composition of the present invention to an organic solvent. Pulp mats are impregnated with the dissolved liquid and perfumes are added as needed to make mats for electric mats, or the composition of the present invention is kneaded with an inorganic carrier such as talc or clay and heated as granules when used. The composition of the present invention may be impregnated into a small block of asbestos, ceramic, alumina, etc. and then fumigated by electric heating. Next, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited to these Examples. Example 1 500 mg of compound A and 200 mg of the phenolic stabilizer shown by compound number (1) were dissolved in 2 ml of acetone,

Example 2 100 mg of Compound A, 50 mg of the phenolic stabilizer represented by Compound No. (3), and a small amount of fragrance are dissolved in 1 ml of hexane, and a conventional pulp mat for electric mats is impregnated with this solution to obtain an electric mat formulation. Example 3 A mosquito coil preparation is obtained by kneading 100 mg of Compound A and 50 mg of the phenolic stabilizer represented by Compound No. (4) with a mosquito coil base material and punching the mixture into the shape of an incense stick. Example 4 Each amount of compound A and compound number shown in the table below
The phenolic stabilizer shown in (2) was dissolved in 2 ml of acetone, and a ceramic porous plate 4 cm square and 1.2 cm thick was impregnated with this solution. When these preparations were tested for insecticidal efficacy by the method described below, very good insecticidal efficacy was obtained as shown in the table below. Insecticidal efficacy test method: Waist-high glass sheath (diameter 14cm, height 7cm) containing 10 adult German cockroaches
cm) were installed in the four corners of the floor of a 28m3 living room.
Two of the glass shelves are not covered at all, and the remaining two glass shelves are fitted with lids that cover four-fifths of the entire area of the open upper part. the
A temperature-adjustable electric heater will be installed in the center of the 28m3 living room, the above-mentioned chemical-treated ceramic perforated plate will be placed on top, the electric heater will be energized, and fumigation will be carried out at a constant heating temperature. After 60 minutes, the cockroaches were collected, transferred to a new container, and fed and watered for 24 hours to determine mortality rate.

[Table] Example 5 500 mg of compound A and 100 mg of the phenolic stabilizer shown by compound number (2) are dissolved in 2 ml of acetone, and a ceramic porous plate of 4 cm square and 1.2 cm thick is impregnated with this solution. On the other hand, 500mg of compound A only
was dissolved in 2 ml of acetone and impregnated into a porous ceramic plate of the same shape. Each of these is placed in an electric heater and heated at 250°C and 300°C. Place a hanging mirror funnel on top of the heater, and assemble the device so that it leads to a 30 cm long Liebig condenser, and then to a glass tube filled with 5 g of silica gel (60-80 mesh) and plugged with cotton at both ends. ,
Air is drawn through these devices at a rate of 20 per minute to collect the fumigated Compound A. Extract the collected compound A with acetone,
The volatilization rate was measured by analysis. The volatilization rate was calculated using the following formula. Volatilization rate (%) = Number of mg of collected compound A / 500 x 100 The volatilization rate under each condition is as shown in the table below,
The phenolic stabilizer of compound number (2) effectively increased the stability of the compound and obtained a high volatilization rate.
