Description

[Detailed description of the invention] <Industrial application field> The present invention relates to an insecticidal aqueous aerosol.

<Prior art and problems to be solved> 2,4-dioxo-1-(2-propynyl) represented by the formula
imidazolidin-3-ylmethyl chrysanthemate (
Hereinafter, it will be referred to as compound A. ) is a compound described in Japanese Patent Publication No. 60-9715, and it is known that it can be used as an active ingredient in insecticidal aqueous aerosols, but the aerosols do not necessarily have sufficient insecticidal efficacy and have not yet been put into practical use. not present.

Means for Solving the Problems The present inventors have conducted extensive studies with the aim of enhancing the insecticidal efficacy of an insecticidal aqueous aerosol containing Compound A as an active ingredient.
(a) Compound A (b) One or more types having 12 to 2 carbon atoms
0 aromatic hydrocarbon and (C) kerosene]
The mixing ratio of (b) and (C) is 1:8 to 1:0 by weight)
, by further adding water, emulsifier and propellant.
The inventors have discovered that the object can be achieved, leading to the present invention.

In addition to Compound A, the insecticidal aqueous aerosol of the present invention may also contain one or more compounds selected from Group A below.

1-triamine [Cyromasin] Among the compounds selected from Compound A and Group A used in the present invention, where optical isomers and geometric isomers exist, any isomers having insecticidal activity and mixtures thereof are included in the present invention. Can be used in Compound A and the compound selected from Group A are each usually contained in an amount of 0.0001 to 2% by weight based on the total amount of the insecticidal aqueous aerosol.
, 0.001 to 5%.

Examples of the aromatic hydrocarbons used include octylbenzene, dodecylbenzene, and phenylxylylethane. The blending amount of the aromatic hydrocarbon and kerosene is usually 1 to 3 by weight based on the total amount of the insecticidal aqueous aerosol agent.
It is 0%. Examples of emulsifiers include sorbitan monolaurate, sorbitan monooleate, etc., and the amount of the emulsifier is usually 0.0% by weight based on the total amount of the aerosol.
It is 1 to 5%.

As water, deionized water, distilled water, etc. are used, and the amount is usually 20 to 80% by weight based on the total amount of the aerosol.
%.

Examples of the propellant include liquefied petroleum gas (LPG), and the amount thereof is usually 20 to 80% by weight based on the total amount of the aerosol agent.

The aerosol insecticide of the present invention may further contain synergists, fragrances, fungicides, rust preventives, and the like.

The synergist used is, for example, α-[2-(2
-butoxyethoxy)ethoxy]-4゜5-methylenedioxy-2-propyltoluene (biveronyl butoxide), octachlorodipropyl ether (S-42))
, N-(2-ethylhexyl)-bicyclo(2,2,1
) hebut-5-ene-2,3-dicarboximide and the like.

Examples of the rust preventive include ammonium benzoate, sodium benzoate, and the like.

The insecticidal aqueous aerosol of the present invention can be prepared by adding, for example, a predetermined amount of Compound A, the above-mentioned aromatic hydrocarbon and kerosene, an emulsifier, and, if necessary, other insecticides, synergists, fragrances, bactericidal agents, etc. at room temperature or After mixing and dissolving the mixture under heating and placing it in an aerosol container, deionized water or deionized water with a rust preventive dissolved therein is poured into the aerosol container, a valve part is attached to the container, and the propellant is passed through the valve part. It is prepared by pressure filling.

Examples of pests against which the insecticidal aqueous aerosol of the present invention prepared in this way are effective include the following.

Lepidopteran pests, Diptera pests such as burrs and carp moths, Culex mosquitoes such as Culex mosquitoes and Culex pipiens, Aedes mosquitoes such as Aedes albopictus and Aedes albopictus, Anopheles insects such as Aedes albopictus, Anopheles insects such as Chironomidae, House flies, and Common houseflies. , black flies, black flies, red flies, seed flies, onion flies, etc.; fruit flies, fruit flies, butterfly flies, horseflies, black flies, sand flies, etc., reticulopteran pests; German cockroaches, black cockroaches, American cockroaches, black kites. Hymenoptera pests such as Japanese cockroaches and Japanese cockroaches; Isoptera pests such as sawflies such as ants, wasps, wasps, and turnip bugs; ticks such as Yamato termites and Japanese termites; indoor dust mites such as Ixodes mites; Examples: The present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited to these Examples.

In addition, in the following examples, parts represent parts by weight.

Example 1 Obtained by mixing and dissolving 0.3 parts of Compound A (d-trans form on the acid side), 1.0 parts of dodecylbenzene, 7.7 parts of kerosene, and 1.0 parts of sorbitan monolaurate under heating. Pour the aerosol stock solution into an aerosol container, then add 5 liters of deionized water.
After adding 0.0 part, attach a valve part to the container,
40.0 parts of LPG was filled under pressure through the valve portion to obtain an aerosol.

Aerosols obtained in the same manner as above are shown in Table 1.

For each aerosol of Example 1-10 and Comparative Examples 1 to 3, the knockdown efficacy KT50 (time required for 50% knockdown) against flies and mosquitoes was determined by the CS M A aerosol test method (beat gradient chamber method). The results of the investigation are shown in Table 2.

Table 2 Each aerosol shown in Table 3 was obtained in the same manner as in Example 1.

Table 4 shows the results of examining the knockdown efficacy against flies and mosquitoes for each of the aerosols of Example 11 and Comparative Examples 4 to 7 using the C5M5 aerosol test method.

Table 4 Table 6 shows the results of examining the knockdown efficacy against flies and mosquitoes using the C8MA aeroaerosol test method for each of the aerosols of Examples 12 to 17.

Table 6 <Effects of the Invention> The insecticidal aqueous aerosol of the present invention has excellent insecticidal efficacy.
