Description

[Technical Field]

[0001] This disclosure relates to a quantitative spray aerosol for controlling flying insects outdoors. [Background technology]

[0002] In recent years, the number of people who engage in activities such as home gardening, yard work, and outdoor recreation has increased. Consequently, people are increasingly troubled by flying insects such as mosquitoes in and around bushes, trees, and other shaded areas.

[0003] In contrast, Patent Document 1 discloses an insect repellent aerosol composition for ground spraying that contains an insecticidal component with a vapor pressure within a predetermined range, a lipophilic solvent, and a propellant. The insect repellent aerosol composition for ground spraying disclosed in Patent Document 1 is said to be able to prevent flying insects from entering a desired area by spraying it on the ground in that area. Patent Document 1 also discloses an aerosol product in which the insect repellent aerosol composition for ground spraying is contained in a metered-dose spray type aerosol container.

[0004] Furthermore, Patent Document 2 discloses a method for enhancing the control efficacy of an aerosol for controlling flying insects used outdoors, which involves incorporating a specific auxiliary agent that is liquid at room temperature and has a boiling point of 180°C or higher. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2012-149007 [Patent Document 2] Japanese Patent Publication No. 2018-095577 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] Incidentally, in quantitative spray aerosols used outdoors, such as those described in Patent Document 1, there is a need to enhance efficacy against pests while preventing phytotoxicity to plants.

[0007] Therefore, it is conceivable to incorporate an auxiliary agent as disclosed in Patent Document 2, but incorporating such an auxiliary agent would lead to an increase in the cost of aerosol products for controlling flying insect pests.

[0008] Therefore, the objective of the technology disclosed herein is to provide a configuration for a metered-dose spray aerosol for outdoor use that provides sufficient efficacy against pests without the use of special additives, while suppressing phytotoxicity to plants. [Means for solving the problem]

[0009] Through diligent research, the inventors of this application discovered that by setting the particle size within a predetermined range in a quantitative spray type aerosol for outdoor use, sufficient pest control effects can be obtained while suppressing phytotoxicity, and thus completed the aerosol product for controlling flying insects according to this disclosure.

[0010] In other words, the aerosol product for controlling flying insects according to this disclosure can be assumed to be a quantitative spray type aerosol product for controlling flying insects in which an aerosol composition containing an insecticidal component, a solvent, and a propellant is filled into an aerosol container. Furthermore, the aerosol product for controlling flying insects is used outdoors, and the average particle diameter D50 at a distance of 50 cm from the nozzle of the aerosol product for controlling flying insects is 29 μm or more.

[0011] The aforementioned solvent may be a hydrocarbon solvent such as paraffin, isoparaffin, or kerosene.

[0012] The proportion of the solvent in the aerosol composition can be 35 w / w% or less. The proportion of the solvent in the aerosol composition can also be 10 w / w% or more.

[0013] The ratio of the aerosol stock solution containing the insecticidal component and the solvent to the propellant can be 15 / 85 or more and 30 / 70 or less. Further, the ratio of the aerosol stock solution to the propellant can also be 10 / 90 or more and 50 / 50 or less.

[0014] The insecticidal component may contain a pyrethroid compound having a vapor pressure of 1.0×10 -5 Pa or more at 25°C. Further, the insecticidal component may contain transfluthrin and / or metofluthrin.

[0015] In another aspect of the present disclosure, a quantitative spray type aerosol product for controlling flying pests, in which an aerosol composition containing an insecticidal component, a solvent, and a propellant is filled in an aerosol container, is prepared. Outdoor, a method for controlling flying pests by spraying an aerosol stock solution containing an insecticidal component and a solvent so that the average particle diameter D50 at a distance of 50 cm from the spray port of the aerosol product for controlling flying pests is 29 μm or more may also be used. The object to be sprayed may be, for example, grass, trees, the ground, etc.

Advantages of the Invention

[0016] According to the aerosol product for controlling flying pests according to the present disclosure, sufficient efficacy against pests can be obtained without using a special auxiliary agent, and phytotoxicity to plants can be suppressed.

Brief Description of the Drawings

[0017] [Figure 1] FIG. 1 is a perspective view of an aerosol product for controlling flying pests according to an embodiment of the present invention. [Figure 2] FIG. 2 is a schematic diagram of a test apparatus used in the basic test. [Figure 3] FIG. 3 is a schematic diagram of a test apparatus used in the adhesion confirmation test 2.

Modes for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Note that the following description of the preferred embodiments is merely illustrative in nature and is not intended to limit the present invention, its applications, or its uses.

[0019] FIG. 1 shows an aerosol product 1 for controlling flying pests according to an embodiment of the present invention. The aerosol product 1 for controlling flying pests includes an aerosol container 2, a cap 3, an injection button 4, and a nozzle 5. The aerosol product 1 for controlling flying pests is used outdoors. Therefore, the aerosol product 1 for controlling flying pests can also be referred to as an outdoor aerosol product, for example.

[0020] The aerosol container 2 is a pressure-resistant container, and a valve mechanism (not shown) is provided at the upper part. The valve mechanism is configured to be operable by the injection button 4, and when it is operated once by the injection button 4, it is a metering injection type valve mechanism that injects a fixed amount of the contents of the aerosol container 2 and then stops. Therefore, the aerosol product 1 for controlling flying pests is a metering injection type aerosol product. The above fixed amount is the injection amount per injection operation, and can be, for example, in the range of 0.1 mL or more and 3.0 mL or less, but may preferably be 0.2 mL or more and 2.0 mL or less.

[0021] The cap 3 is a member attached to the upper part of the aerosol container 2. The nozzle 5 is integrated with the injection button 4 and is formed in a cylindrical or tubular shape for injecting the contents injected from the aerosol container 2 through the valve mechanism. An injection port 5a is opened at the tip of the nozzle 5. The structures and shapes of the aerosol container 2, the cap 3, the injection button 4, and the nozzle 5 are examples, and those other than the illustrated structures and shapes can also be used.

[0022] Only one injection port 5a may be provided, or a plurality of injection ports 5a may be provided. When a plurality of injection ports 5a are provided, they may be arranged side by side in the vertical or horizontal direction, for example, or may be provided so as to surround a certain point.

[0023] The diameter of the nozzle 5a can be, for example, 0.5 mm or more and 2.0 mm or less. The passage inside the nozzle 5 may be of the diffusion type or the straight-line type, and is not particularly limited.

[0024] The average particle diameter D50 at a distance of 50 cm from the nozzle 5a is 29 μm or larger. The upper limit of the average particle diameter D50 at a distance of 50 cm from the nozzle 5a is 61 μm or smaller. The size of the average particle diameter D50 can be changed by, for example, the diameter of the nozzle 5a, the shape of the passage inside the nozzle 5, the amount of propellant (described later), the amount of aerosol concentrate, etc.

[0025] Here, we will explain the method for measuring the average particle diameter D50. Although not shown in the diagram, the aerosol composition is sprayed from a position where the horizontal distance between the laser beam, which is irradiated from the laser light irradiation unit of the particle diameter measuring instrument to the light receiving unit, and the spray nozzle 5a is 50 cm, so that the aerosol concentrate, which is the sprayed material, passes through the laser beam in a direction perpendicular to the direction of irradiation. Measurements are taken while the aerosol composition is being sprayed, and the average particle diameter D50 can be determined by analyzing the particle size distribution of the aerosol composition using an automatic calculation processing unit. This method for measuring the average particle diameter D50 is conventionally known. The measuring instrument used was the LDSA-SPR-1500A manufactured by Microtrac-Bell Co., Ltd., and the particle size distribution measurement software Aerotrac was used.

[0026] The measuring equipment was set to the following conditions.

[0027] Measurement method: Auto-start Calculation method: Histogram Measurement automatically begins when a particle is detected in the laser beam's optical path. The particle diameter was measured five times at 0.02-second intervals, and the average of the second to fifth measurements was used as the average particle diameter. The first measurement was excluded because it was taken immediately after particle detection and the value was unstable.

[0028] Aerosol container 2 is filled with an aerosol composition containing an aerosol concentrate and a propellant for spraying the aerosol concentrate. The aerosol concentrate contains at least an insecticidal component and a solvent.

[0029] The ratio (liquid volume ratio) of the aerosol concentrate containing the insecticidal component and solvent to the propellant is defined as the liquid-gas ratio (liquid / gas). The liquid-gas ratio of the aerosol composition in this embodiment is in the range of 10 / 90 to 50 / 50, but it can also be 15 / 85 to 30 / 70.

[0030] The insecticidal component contains pyrethroid compounds that evaporate highly at room temperature. Specifically, the insecticidal component has a vapor pressure of 1.0 × 10⁻⁶ at 25°C. -5 It contains pyrethroid compounds with a vapor pressure of 1.0 × 10⁻⁶ Pa or higher. The insecticidal component has a vapor pressure of 1.0 × 10⁻⁶ Pa at 25°C. -4 It may contain pyrethroid compounds with a Pa or higher rating.

[0031] Examples of usable insecticidal ingredients include transfluthrin, metofluthrin, profluthrin, empenthrin, terrarethrin, and tetraflumethrin. Any one of these may be included as an insecticidal ingredient, or any two or more may be included. Transfluthrin and metofluthrin are particularly preferred, and both transfluthrin and metofluthrin may be included as insecticidal ingredients, or only one of them may be included.

[0032] The concentration of the insecticidal component in the aerosol composition (mg / v% of the total liquid) is specified to be in the range of 0.1 to 30.

[0033] Any solvent that can dissolve the insecticidal component is acceptable, such as hydrocarbon solvents. Examples of hydrocarbon solvents include paraffin, isoparaffin, and kerosene, and the solvent may contain only one of these, or two or more. As will be explained in detail later, using a hydrocarbon solvent results in excellent adhesion of the aerosol concentrate and active ingredient to the target object when the aerosol concentrate and active ingredient are sprayed onto the target object.

[0034] The amount of solvent in the aerosol composition should be sufficient to dissolve the insecticidal component. In this embodiment, the proportion of solvent in the aerosol composition is, for example, 35 w / w% or less. The lower limit of the proportion of solvent in the aerosol composition is 10 w / w% or more.

[0035] While there are no particular limitations on the types of propellants that can be used, examples include liquefied petroleum gas (LPG), dimethyl ether (DME), and compressed gases (carbon dioxide, nitrogen, nitrous oxide). Any one of these may be used as a propellant, or any two or more may be used as propellants.

[0036] The aerosol concentrate may contain other ingredients. Examples of other ingredients include other insecticides, insect repellents, animal repellents, antiseptics and preservatives, surfactants, deodorants, pH adjusters, thickeners, fragrances, dyes, potency enhancers, UV absorbers, antioxidants, etc. Only one of these may be included as other ingredients, or two or more may be included as other ingredients.

[0037] By spraying the aerosol product 1 for controlling flying insects outdoors, insecticide treatment can be applied. The amount of insecticide (pyrethroid compound) applied in this insect control treatment is, for example, 1 mg / m². 2 More than 100mg / m 2 The following range applies: Insecticide treatment amount of 1 mg / m². 2By setting it as above, sufficient control efficacy of pests by the insecticidal component can be obtained. Also, by setting the treatment amount of the insecticidal component to 100 mg / m 2 or less, unnecessary consumption of the insecticidal component can be suppressed. The treatment amount of the insecticidal component in the pest control treatment may be, for example, 10 mg / m 2 or more and 50 mg / m 2 or less. By setting the treatment amount of the insecticidal component to 10 mg / m 2 or more, the control efficacy of pests by the insecticidal component can be further enhanced.

[0038] Flying pests to be controlled by the aerosol product 1 for controlling flying pests include, for example, mosquitoes, flies, wasps, midges, crane flies, and fleas. The aerosol product 1 for controlling flying pests exhibits control efficacy against these flying pests, and particularly exhibits sufficient control efficacy against mosquitoes. Examples of the above-mentioned mosquitoes include Aedes albopictus, Ochlerotatus japonicus, Aedes vexans, Aedes aegypti, Aedes albopictus, Aedes atropalpus, Aedes notoscriptus, and Aedes albopictus. Examples of the above-mentioned flies include house flies, blow flies, blue flies, and flesh flies. Examples of the above-mentioned wasps include Drosophila melanogaster, Drosophila simulans, Drosophila yakuba, and Drosophila ananassae. Examples of the above-mentioned midges include Chironomus plumosus. Examples of the above-mentioned crane flies include Tipula paludosa, Tipula oleracea. Also, not only flying pests but also crawling pests are subject to the control effect. For example, ticks, mites, etc. can be mentioned.

[0039] The place where the aerosol product 1 for controlling flying pests is used may be outdoors, and the place is not particularly limited. The place where the aerosol product 1 for controlling flying pests is used includes, for example, verandas, entrances, around houses, garages (parking lots, bicycle parking areas), gardens, around tents, inside tents, outdoor toilets, old tires, stumps, puddles, thickets, grasslands, around garden trees, shaded areas, the ground, fishing ports, etc.

[0040] When using the flying insect control aerosol product 1, you can spray it into the air, towards the ground, downwards, upwards, or directly onto insects, objects, or buildings.

[0041] For example, by spraying the aerosol product 1 for controlling flying insects according to this embodiment onto the ground or bushes (including grass and trees), the active ingredient (insecticide) adheres reliably to the ground or bushes. For example, since mosquitoes tend to rest in grassy areas and bushes during the day, it is possible to control the mosquitoes that land there. In addition, the active ingredient that adheres to the ground or bushes is re-evaporated, so the control effect can be maintained for a long period of time.

[0042] When spraying the aerosol product 1 for controlling flying insects onto an object, the distance between the object and the nozzle 5a should be between 50 cm and 100 cm. This reduces the amount of insecticide that scatters while ensuring that the spray adheres securely to the object.

[0043] Furthermore, when spraying the aerosol product 1 for controlling flying insects, 1m 2 The number of sprays should be between one and ten. This ensures that the insecticide adheres reliably to the target object while guaranteeing effectiveness against flying insects with the optimal amount of pesticide applied.

[0044] The flying insect control method can be implemented by spraying the flying insect control aerosol product 1 outdoors towards the target object. First, prepare the flying insect control aerosol product 1, which is filled with the aerosol composition and propellant. Point the nozzle 5a of the flying insect control aerosol product 1 towards the target object, such as the ground or bushes (grass, trees, etc.). Then, operate the spray button 4 of the flying insect control aerosol product 1 to spray the aerosol composition so that the average particle size D50 at a distance of 50 cm from the nozzle 5a is 29 μm or more. This will cause the insecticidal active ingredient to adhere to the ground, grass, trees, etc., thereby controlling flying insects. [Examples]

[0045] The following describes examples of the present invention, but the present invention is not limited to these examples.

[0046] [Mosquito repellent test (basic test)] Test insect: Culex pipiens (female) Test materials: Examples 1-9 shown in Table 1 and Comparative Examples 1-5 shown in Table 2 The test method was as follows: First, a filter paper with a diameter of 9 cm was placed horizontally, and the nozzle 5a was positioned downwards at a height of 1 m above the filter paper. The test agent was sprayed once from the nozzle 5a and left to stand for 3 hours. The amount sprayed each time was 1.0 mL.

[0047] As shown in Figure 2, a filter paper 100 sprayed with the test agent was placed on a circular glass plate 101, and the filter paper 100 was surrounded by a glass ring 102. The upper end of the glass ring 102 was covered with a mesh nylon net 103 having a mesh size that prevents mosquitoes from passing through.

[0048] A glass cylinder 104 containing 20 test insects was placed on a glass ring 102, exposing the test insects to the active ingredient. Simultaneously with the exposure, a plate 105 having one 5 cm diameter hole 105a was placed in between, and a glass cylinder 107, with its upper end sealed with a mesh nylon net 106 having a mesh size that prevents mosquitoes from passing through, was placed on top of it.

[0049] Of the test insects, those that escaped to the upper part through hole 105a of plate 105 and those that were knocked down at the lower part were counted as the number of insects that were driven out. The number of insects driven out 3 hours and 6 hours after exposure to the insecticide were counted, respectively. The ratio of the number of insects driven out to the total number of test insects was calculated as the driving-out rate.

[0050] Furthermore, a 9 cm diameter filter paper that was not sprayed with the test agent was designated as the untreated group, and the same test was conducted. The repellency rate was calculated using the following formula.

[0051] Repellent rate (%)=(TC) / (100-C)×100 C: Eradication rate in untreated areas (%) T: Eviction rate from treatment area (%)

[0052] [Table 1]

[0053] [Table 2]

[0054] As shown in Examples 1 to 9, it was found that the repellency rate was high when the solvent was a hydrocarbon-based solvent, the liquid-gas ratio was 15 / 85 to 50 / 50, and the average particle size D50 was 29 μm to 61 μm. Furthermore, the vapor pressure at 25°C was 1.0 × 10⁻⁶. -5 By including pyrethroid compounds with a Pa or higher, both the repellency rate after 3 hours and after 6 hours can be increased. Furthermore, by keeping the proportion of solvent in the aerosol composition at 35 w / w% or less, both the repellency rate after 3 hours and after 6 hours can also be increased. The same applies to the practical tests described later.

[0055] However, the efficacy does not change even if the liquid-gas ratio exceeds 30 / 70. On the other hand, from the perspective of suppressing phytotoxicity, a smaller liquid-gas ratio is considered preferable. Therefore, it may be preferable to set the upper limit of the liquid-gas ratio to 30 / 70.

[0056] Comparative Example 1, with an average particle size of 15 μm, and Comparative Example 2, with an average particle size of 11 μm, both showed low repellency rates after 3 hours and 6 hours. Comparative Example 3, which used isopropanol as the solvent, also showed low repellency rates after 3 hours and 6 hours. Furthermore, Comparative Examples 4 and 5, which used isopropyl myristate as the solvent, showed high repellency rates after 6 hours, but low repellency rates after 3 hours, at around 42-45%. Similar repellency rates were observed for flying insects other than Culex pipiens.

[0057] [Mosquito repellent test (field test)] Test insects: The presence of Asian tiger mosquito (Aedes albopictus) and Japanese aedes mosquito (Armigeres subalbatus) was confirmed in the field.

[0058] Test material: Example 3 Location: Thicket in Ishigaki City, Okinawa Prefecture (Itokazu Utaki, Ube Utaki) Itokazu Utaki: Temperature 25℃, Humidity 78% Ube Ontake: Temperature 24.1℃, Humidity 90% The test method was as follows: First, the number of mosquitoes flying around each location was counted before spraying the test agent. The test agent was sprayed once at each of several locations at 1m intervals from a distance of 1m from the bush with the spray nozzle 5a. After treatment, the number of mosquitoes flying around was counted 3 hours, 6 hours, 8 hours, and 12 hours later. The amount sprayed each time was 1.0 mL.

[0059] The outdoor repellency rate was calculated using the following formula.

[0060] Outdoor repellency rate (%) = (1 - number of birds after treatment / number of birds before treatment) × 100

[0061] [Table 3]

[0062] Example 3 showed a high repellency rate, with a repellency rate of over 80% even 12 hours after treatment outdoors. Similar repellency rates were observed against flying insects other than Culex pipiens. Similar repellency rates were also observed in Examples 1, 2, 4-9.

[0063] [Adhesion Confirmation Test 1] We investigated the degree of adhesion of the aerosol concentrate when spraying aerosol product 1 for controlling flying insects onto an outdoor bush.

[0064] Test materials: Example 3, Comparative Example 3 The test method was as follows: First, a filter paper with a diameter of 9 cm was attached to the wall at a height of 150 cm from the ground. The test agent was sprayed 10 times onto the filter paper from the same height as the wall and from a nozzle 5a 40 cm away from the filter paper. The amount sprayed each time was 1.0 mL. After that, to prevent evaporation of the solvent, the filter paper was placed in a poly cup and weighed using a precision balance. The above method was repeated twice, and the average value was calculated to determine the "amount of agent adhering to the filter paper attached to the wall."

[0065] Furthermore, the filter paper was placed on the ground, and the test agent was sprayed 10 times onto the filter paper from a nozzle 5a 40 cm away from the filter paper. The amount sprayed each time was 1.0 mL. Afterwards, to prevent evaporation of the solvent, the filter paper was placed in a plastic cup and weighed using a precision balance. The above method was repeated twice, and the average value was calculated to determine the "amount of agent adhering to the filter paper placed on the ground."

[0066] [Table 4]

[0067] By using a hydrocarbon-based solvent instead of an alcohol-based solvent, the adhesion rate of the aerosol concentrate increased. Similar adhesion rates were observed in other examples 1, 2, and 4-9.

[0068] [Adhesion Confirmation Test 2] In Adhesion Confirmation Test 2, not only was the adhesion rate of the aerosol concentrate of Aerosol Product 1 for Flying Insect Control confirmed, but the adhesion rate of the actual active ingredient was also confirmed.

[0069] Test materials: Example 3, Comparative Example 3 The test method is as follows: First, as shown in Figure 3, a filter paper 200 with a diameter of 24 cm was placed on the ground, the nozzle 5a was pointed downwards, and the aerosol container 2 was fixed to the stand 210 so that the distance between the nozzle 5a and the filter paper 200 was 1 m.

[0070] The test agent was sprayed onto filter paper 200, and the amount of active ingredient adhering to the filter paper 200 was quantitatively analyzed by gas chromatography. Since the spray range of the test agent varied, the area of ​​the spray circle expected from the spray angle of the test agent was determined, and the quantified amount of active ingredient was corrected. The above method was repeated seven times, and the average value was taken as the measured value.

[0071] [Table 5]

[0072] By using a hydrocarbon-based solvent instead of an alcohol-based solvent, the adhesion rate of the active ingredient increased. Similar adhesion rates were observed in other examples 1, 2, and 4-9.

[0073] (Drug-induced harm testing) A test was conducted to confirm whether or not phytotoxicity occurred when the aerosol product 1 for controlling flying insects adhered to plants after being sprayed towards the ground.

[0074] Test plant: Wild grass (cut into approximately 15cm x 20cm pieces) Test material: Example 2 The test method was as follows: First, photographs of the test plants were taken before spraying the test agent. Then, the test agent was applied from a predetermined distance a predetermined number of times. The condition one week after spraying was compared with the pre-spray photograph to check for phytotoxicity. A total of five conditions were tested, including treatment groups with varying spraying frequency and distance, and an untreated group where no test agent was sprayed.

[0075] [Table 6]

[0076] Under test condition 4, some areas of poor grass growth were observed. Under all other conditions, no phytotoxicity was observed. Similar results were obtained for other examples 1, 2-9. It is believed that phytotoxicity will not occur unless the spray is applied at close range and multiple times to the plants. Therefore, aerosol product 1 for controlling flying insects can be used with little concern about phytotoxicity.

[0077] The embodiments described above are merely illustrative in all respects and should not be interpreted restrictively. Furthermore, any modifications or changes that fall within the equivalent scope of the claims are all within the scope of the present invention. That is, the present invention also includes aerosol products for controlling flying insects, aerosol compositions, and flying insect control using aerosol products for controlling flying insects.
