JPS6049161B2 - Composition for killing ants - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composition for stage ants containing triallyl isocyanuric acid ester (hereinafter abbreviated as "TAE") and a pyrethroid insecticide as active ingredients.

The present inventors have discovered that TAE exhibits activity against wood-decaying fungi and also exhibits strong activity against termites, which cause great damage to wood and cellulosic materials.

The characteristics of this TAE showing activity against termites include:
At relatively high dosages, it exhibits strong tier ant activity, and at low dosages, it exhibits the effect of preventing termite feeding damage and exhibits tier ant activity.

Moreover, TAE exhibits residual activity against termites over a long period of time. On the other hand, as the pyrethroid insecticide having a step ant action used in the present invention, for example, (+)
-3-aryl-1-methyl-4-oxo-2-cyclopentenyl-(10)-trans-chrysanthemate
(hereinafter referred to as "Esperol"), 3-phenoxybenzylosis/trans-3-(2,2-dichlorovinyl)-2,2-dimethylpropane-1-carboxylate (hereinafter referred to as "Permethrin") )
, (±)-3-aryl-2-methyl-4-oxo2-
Cyclopentele-(±)-cis/trans-chrysanthemate (hereinafter referred to as "allethrin"), 5-benzy-3-furylmethyl-(±)-cis/trans-chrysanthemate (hereinafter referred to as "common name resmethrin") , 5-benzyl-3-furylmethyl-(+)-cis/trans-chrysanthemate (hereinafter referred to as "d-resmethrin"), N-(3,4,5,6-tetrahydrophthalimido)methyl-(±)- Cis/transucrysan 1 temate (hereinafter generic name "phthalthrin")
) and 3-phenoxybenzyl-(+)-cis/trans-chrysanthemate (hereinafter referred to by the common name "d-phenotrin").

The pyrethroid insecticide's activity against termites is characterized by its rapid effectiveness even at low dosages and low toxicity.

As described above, the present invention utilizes the characteristics of TAE and pyrethroid insecticides, and by mixing these two types of agents, an extremely useful termite-killing composition that has both residual effect and immediate effect in a small amount is produced. It is.

Furthermore, the composition of the present invention is characterized by not only the additive activities of TAE and pyrethroid insecticides, but also the fact that their action sites and mechanisms of action against termites are different and act synergistically. . When mixing L-positive and pyrethroid insecticides in the composition of the present invention, since TAE is liquid at room temperature and both pyrethroid insecticides and pyrethroid insecticides are easily soluble in various solvents, each component can be mixed in a wide variety of ways depending on the purpose of use and usage situation. They can be mixed as appropriate within a range.

In order to most effectively exhibit the effects of the composition of the present invention,
The mixing ratio of pyrethroid insecticide to TAE is 2~
40% (wt%) is most preferred. When carrying out the present invention, since TAE, which is one of the components of the composition of the present invention, is a stable compound and is liquid at room temperature, it is possible to use the composition as it is.

However, in order to most effectively achieve the purpose of the present invention, it is preferable to use it as an oil or emulsion. It can also be used as a wettable powder, suspension agent, powder, granule, aerosol, fumigant, or fumigant depending on the purpose or situation. In formulation, the carrier may be solid, liquid or gas, or a combination thereof.

Examples of the carrier here include talc, clay, kaolin, diatomaceous earth, white carbon, calcium carbonate, potassium chlorate, saltpeter, wood flour, nitrocellulose, starch, gum arabic powder, water, alcohol, kerosene, Naphtha, xylene, methylnaphthalene, benzene, acetone, air, nitrogen, carbon dioxide, freon, vinyl chloride,
Propane, butane, etc. are used. Further, auxiliary agents such as spreading agents, emulsifiers, dispersants, wetting agents, etc. may be added to the composition of the present invention.

Depending on the purpose of use, the composition of the present invention may also be used to kill other insects.
It can also be used in combination with disinfectants, fungicides, and preservatives. In actual use, it goes without saying that the content of the composition of the present invention can be varied over a wide range of concentrations depending on the use situation, purpose of use, or form of preparation; however, the generally preferred concentration is 0.1 to 10. A range of %4C is suitable. Also,
The composition can be treated by any appropriate method such as inhalation, spraying, coating, or immersion treatment on wood materials, or soil treatment. Next, an explanation will be given using an experimental example.

Experimental example Efficacy test against house termites Diameter 9C! RL circular paper was treated with 1 ml of an acetone solution containing the active ingredients of each drug at a predetermined concentration and air-dried, and this paper was placed on the bottom of a Petri dish with a diameter of 9 cm and impregnated with 1 ml of water.

Next, 20 worker ants of the domestic termite taken out from the pine wood were placed in the container, covered with a glass lid, and kept at a constant temperature of 25±2° C., and the subsequent progress was observed. The results are shown in the table below. Next, an example will be given and explained.

Example 1 TAE 4 parts by weight Esvirol 0.4 Kawakazol (manufactured by Kawasaki Kasei Co., Ltd.) 95.6 These were mixed well and used as an oil agent.

Example 2 TAE 40 parts by weight Permethrin 10 Dodecylbenzyl sulfonic acid calcium salt 5 Polyoxyethylene alkyl allyl ether 5 Xylene 40 These were thoroughly mixed and used as an emulsion.

Example 3 TAE 4 parts by weight Allethrin 0.5 White carbon 3 Clay 92.5 These were mixed well and ground to use as a powder.
