Description

[0001] The present invention relates to a method for manufacturing insecticidal compositions for antimicrobial compositions,

The present invention relates to a method for producing an insecticidal composition, and more particularly, to a method for producing an insecticidal insecticidal composition exhibiting an excellent effect on an insecticidal insecticide, particularly an insecticidal and insecticidal effect on an insecticidal ant.

The ants are typical social insects. The ants that are problematic as domestic hygiene insects are Monomorium pharaonis, Formica japonica, Camponotus Japonicus, and Formica Yessensis. The ants are chemical workers that use chemical agents such as alarm pheromone and trail pheromone as a worker.

These ants are able to infect pathogens by contaminating food through contact with foods that people do not eat, by finding food waste or debris in the house through omnivorous buildings and penetrating through building gaps.

Especially, people and pets can cause pain. Ant poisoning can be a serious problem because of sensitivity or weak baby skin causing rash or allergy symptoms.

In this way, aerosol insecticides, installed toxicants, smokeless smoke fuels, chalky contact pesticides and the like are currently used to control hygienic insect pests in residential areas.

On the other hand, ants exhibit different incentives for the same insecticide depending on the species. For example, antiprotozoal ants, which are representative ants of Korea in preparation for ghost ants and crazy ants, show remarkable deterioration in attractiveness. Therefore, it is urgent to develop a composition for an insect pest which exhibits excellent attractiveness and insecticidal effect against various ants including the representative ants such as the Korean ants.

The method for preparing an insect pesticidal composition according to an embodiment of the present invention is a liquid phase, which can be easily used in the form of an aerosol or a spray, and is easily viscous and does not flow easily. In addition, evaporation is prevented, scattering by the wind and evaporation of the solvent are prevented, so that the insecticidal effective time can be prolonged once after the treatment, and a synergistic action with an effective ingredient exhibiting an insecticidal effect is manifested, It is very suitable as an insecticidal insecticide such as excellent manure and insecticidal effect.

Hereinafter, embodiments of the present invention will be described in detail so that those skilled in the art can easily carry out the present invention. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

The method for preparing an insect pesticidal composition according to the present invention comprises mixing an active insecticidal active ingredient, an ionic liquid which is liquid at 25 캜, and an attractant.

The above active insecticidal active ingredient is an active ingredient used for insecticidal ants, and can be used without limitation in the case of known insecticidal insecticidal active ingredients. Non-limiting examples of this include chlorfenapyr, fenpyroximate, pyridaben, rotenone, tebufenpyrad, hydramethylnon, (lufenuron) can be used.

The insecticidal active ingredient may be at least one member selected from the group consisting of hydra-methylene, rotenone, and lufenuron, and may be at least one member selected from the group consisting of 1-methyl-1- Hydramethylnone may be more preferable considering the solubility with biotilpyrrolidinium bis (trifluoromethanesulfonyl) imide, the increased insecticidal effect, and the attracting effect on the host ants.

The active insecticidal active ingredient may be contained in an amount of 0.8 to 5.0% by weight based on the total weight of the composition. If the insecticidal active ingredient is contained in an amount of less than 0.8% by weight, the desired insecticidal effect may not be sufficiently exhibited. The solubility or dispersibility with the ionic liquid may be lowered, and precipitates may be formed, resulting in an increase in the unit price of the product and environmental pollution.

Next, the ionic liquid will be described.

The ionic liquid means an ionic compound (salt) present in a liquid state at 25 ° C. And is distinguished from conventional surfactants in that the ionic liquid is a salt compound in a liquid phase.

The ionic liquid is used as a solvent for the effective insecticidal active ingredient as described above. Due to the nature of the ionic liquid, there is no fear of volatilization due to the absence of steam pressure and the high viscosity, and even when there is no separate container, There is an advantage that it can be easily attached and positioned without flowing down.

The ionic liquid may be used in any liquid at 25 DEG C in a liquid state without limitation.

The above-mentioned ionic liquid can be produced through a known method such as a halide method, a hydroxide method, an acid ester method, a chelate formation method, a neutralization method, or the like, or a commercial product can be purchased and used.

For example, an ionic liquid, which is a nitrogen-containing onium salt, can be reacted with a tertiary amine and alkyl halide to obtain a halide. The obtained halide is reacted with the anion structure (A-) of the desired ionic liquid The desired ionic liquid (R4NA) can be obtained by reacting with an acid (HA) or a salt (MA, M is a cation which forms a salt with a desired anion such as ammonium, lithium, sodium, potassium, etc.). In the hydroxide method, hydroxide (R4NOH) can be obtained by electrolyzing halide (R4NX) by ion exchange membrane method, OH type ion exchange resin method or reaction with silver oxide (Ag ₂ O) , Bromine or iodine may be used). The hydroxide thus obtained can be reacted with an acid or a salt having a desired anion structure in the same manner as in the above halogenation method to obtain the desired ionic liquid (R4NA). The above examples are merely examples, and ionic liquids can be prepared through various known coupling reactions, and a detailed description of the present invention will be omitted.

On the other hand, according to a preferred embodiment of the present invention, in order to manifest the effect of the ionic liquid merely over the solvent, that is, the above-mentioned insecticidal insecticidal effectiveness component and the increased insecticidal effect, and at the same time, The active insecticidal active ingredient may be hydramethylnone, wherein the ionic liquid may be 1-methyl-1-butylpyrrolidinium bis (trifluoromethanesulfonyl) imide. The inventors of the present invention have been studying the use of an ionic liquid as a solvent in which volatilization characteristics are prevented, and have found that, among hydramethylnone and ionic liquids, 1-methyl-1-butylpyrrolidinium bis (trifluoromethanesulfonyl) imide Have found that there is an improved insecticidal effect and a significantly elevated incentive effect on the host ants. Further, in addition to this, it was confirmed that 1-methyl-1-butylpyrrolidinium bis (trifluoromethanesulfonyl) imide and 1-ethyl-3-methylimidazolium heptafluorobutyrate were used together as the ionic liquid It was found that there was an improved insecticidal effect.

At this time, as an ionic liquid, 1-methyl-1-butylpyrrolidinium bis (trifluoromethanesulfonyl) imide was added to 100 parts by weight of 1-ethyl-3-methylimidazolium heptafluorobutyrate More preferably 35 to 40 parts by weight, and if 1-ethyl-3-methylimidazolium heptafluorobutyrate is contained in an amount of less than 35 parts by weight or more than 50 parts by weight An increased salting effect may not be exhibited. Particularly, if it exceeds 50 parts by weight, the attracting effect on the host ants may be significantly lowered.

Next, the attractant is a component that attracts ants to an insecticide composition, and any of the known attractants contained in the insect pest composition can be used without limitation. For example, the attractants may include one or more selected from the group consisting of sugar, cocoa powder, peanut butter, wheat, potato, pheromone and oats. The attractant may be contained in an amount of 10 to 15% by weight based on the total weight of the composition, but is not limited thereto and may be suitably modified according to the purpose.

The above-described cosmetic pesticide composition may further contain other additives such as coloring matters, preservatives and the like in addition to the effective insecticidal active ingredient, the ionic liquid as the solvent and the attractant. The above-mentioned other additives may be used without limitation in known additives contained in the cosmetic insecticide composition, and they may be appropriately included at a known level, so that the present invention is not particularly limited thereto.

The various components described above can be implemented in an open pesticide composition through mixing and stirring at separate room temperature, i.e., at 25 < 0 > C. In the case of stirring, it is preferable to uniformly dissolve and / or disperse the effective insecticidal active ingredient and the attractant in the ionic liquid through mechanical stirring.

The present invention will now be described more specifically with reference to the following examples. However, the following examples should not be construed as limiting the scope of the present invention, and should be construed to facilitate understanding of the present invention.

≪ Example 1 >

1-methyl-1-butylpyrrolidinium bis (trifluoromethanesulfonyl) imide, which is a liquid phase at 25 ° C as an ionic liquid, and sugar and peanut butter as an attractant, (Mixed in a weight ratio of 1: 1), hydramethylnone was contained in an amount of 1.0% by weight of the total composition, the attractant was mixed so as to contain 12% by weight, and the mixed composition was stirred at 25 DEG C and 600 rpm for 2 hours The mixture was mechanically agitated to prepare an antimicrobial composition as shown in Table 1 below.

≪ Examples 2 to 10 >

The ionic liquids were prepared in the same manner as in Example 1 except that the kinds of ionic liquids used were changed as shown in Table 1 below to prepare an insecticidal composition as shown in Table 1 below.

≪ Comparative Examples 1 to 4 >

The composition of the composition as shown in Table 1 below was prepared in the same manner as in Example 1 except that no insecticidal active ingredient was used.

In this case, in Comparative Example 3, water was used instead of an ionic liquid as a solvent.

In Comparative Example 4, a liquid antimicrobial agent (K, K *) containing 1.0 wt% of hydramethylnone as an active ingredient was used.

<Experimental Example 1>

The insecticidal and insecticidal effects of the insecticidal compositions prepared by the examples and the comparative examples were evaluated using insect adults of Monomorium pharaonis. Specifically, 1 ml of the insecticidal composition according to the examples and the comparative examples was treated on the filter paper, and then placed at one end in the isolated space. Then, 200 antiserum ants were put into the opposite end of each insulated space, and the number of ants migrated to the filter paper after 60 minutes was counted. The antifungal antifungals were counted every 5 hours to a new filter paper Replacing and re-inserting were repeated 5 times in total to average the number of attracted ants. Thereafter, the average number of attracted individuals for each of the examples and the comparative examples is shown in the following Table 1, and based on the average number of antagonistic ants attracted by the insecticide according to Comparative Example 4, The percentages of the total number of migratory ants attracted by the mice were expressed as a percentage.

After 5 repetitions, the number of insecticidal ants was counted after 15 days without replacing the filter paper treated with the insecticidal composition, and the insecticidal rate was calculated and shown in Table 1 below.

2) B: 1-ethyl-3-methylimidazolium heptafluorobutyrate

As can be seen in Table 1,

In Comparative Example 3 using only an ionic liquid (Comparative Examples 1 and 2) and using an effective insecticidal active ingredient dissolved in water, it can be confirmed that the mortality rate is significantly lower than in the Examples.

On the other hand, in the case of Comparative Example 3, when water is used as a solvent, all of the composition for insect pest is completely volatilized after 15 days, and only a trace of some solid phase powder is found, so that it is highly desirable as a composition for insect pesticide for a long time Can not be confirmed. In addition, it can be confirmed that the mortality rate of ants is not remarkably low due to the difficulty of continuous induction and ingestion.

Next, in Examples 1 to 3, in which ionic liquid A (1-methyl-1-butylpyrrolidinium bis (trifluoromethanesulfonyl) imide) was combined with various active insecticidal active ingredients It can be confirmed that there is an increased insecticidal and attracting effect according to the combination in Example 1. It can be confirmed that this is an increased effect as compared with Comparative Example 4, which is an insecticidal composition which is the same amount of hydramethylnone as an active ingredient.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the following claims. Those who are engaged in the technology field will understand easily.
