Description

Fumigation, smoking medicine composite of agricultural pesticide

The present invention relates to a fumigation, fumigant composition of agrochemicals for effectively controlling various pests occurring in crops, particularly crops grown in houses.

As the plant cultivation area of various crops increases and the yield per unit area increases, the amount of pesticides used and the number of times of use are increasing. Moreover, since greenhouses are cultivated year round, greenhouses are kept at a constant temperature, so that the environment is very suitable for the breeding of pests.

Conventional control methods for controlling such pests are mainly sprayed by diluting a large amount of water in the pesticide and spraying with a nebulizer. However, since the greenhouse is very hot and humid during the day, it is impossible to wear protective equipment for spraying pesticides such as gas masks, protective clothing, and gloves, so that the sprayer sprays pesticides without any protective equipment. Survival pests become resistant to control, resulting in an increase in the number of control and pesticide use.

When pesticides are sprayed using a pesticide sprayer for manual and automatic pesticide spraying, the spray particles are large and fall to the bottom due to gravity. Strong resistance to pesticides makes it increasingly difficult to control.

In the control efficiency of pesticides, it is very important that the active ingredient of the pesticides reaches the target pests. Therefore, recently, infiltrating transitional pesticides have been developed and used, but there are problems such as effects on crops and long-term residue of pesticides.

There is an ultra-fine particle spraying method as a pesticide spraying method improved the spraying method. The ultrafine particle pesticide spraying method is a method of spraying a high concentration of pesticides diluted with some auxiliary agents such as a solvent and a dispersant in an active ingredient of the pesticide in an ultrafine state. However, pesticide preparation is difficult and expensive, and the spraying equipment is also expensive, so the area covered by the equipment is wide, so that the sprayed spray particles stay in the air for a long time and evaporate before the active ingredient reaches the target, or the distribution of medicinal spraying due to the tipping of the drug. Because of the inconsistency in the amount of drug spraying, there is a problem such as weakness in some areas due to the excessive amount of spraying the medicine or the effect of the drug dropping due to the amount of spraying of the drug.

Another method is fumigation control.

Fumigation control is a method of controlling pests by filling a closed greenhouse with an active ingredient of a fumigating pesticide in a gas or vapor state.

However, pesticides that have an effective ingredient of pesticides have only a few components such as sulfur, so they are not limited to use, and due to the characteristics of the pesticides that have a fumigating effect, the active ingredient is a volatile component and has excellent diffusibility, which easily runs away to the outside. When used in a greenhouse with a relatively low level of pesticides, the efficiency is not high and only low-cost sulfur as a fumigant is mainly used for the control of powdery mildew, a specific pest.

Therefore, in the greenhouse, mainly used the spray method that has been used in the open field crops such as rice, barley, orchard.

Unlike open fields, greenhouses maintain constant temperature and humidity throughout the year, and crops are cultivated, causing severe pest outbreaks. Therefore, pesticides are also used to control these pests. The use of such a large amount of pesticides not only harms people's health due to pesticide pollution. Sprayed pesticides have been a source of pollution, contaminating soil.

Therefore, the soil becomes more and more desolate, so that bacteria or insects that help the plants grow in the soil cannot grow, so that the plants cannot grow healthy. As the plants become weak, the invasion of pests becomes easy, and the occurrence of pests becomes severe. And the amount of usage tends to be increasing, which is the main cause of serial disturbances.

For example, the application of 2,250 liters of the commonly used pesticide, Benomil liquid, by spraying in one hectare reduced the earthworm density by more than 60% (Cooke et al 1974). Effects on microorganisms and earthworms are being published one after another.

Greenhouses have a lot of facility investment on the ground and have to be continuously cultivated for several decades in floating places. Soil contamination by spraying pesticides is a very serious problem.

In the control efficiency of the general spray method, assuming that all spray pesticides reach the target pest area, which is 100%, if one pest is needed to control one pest, one million pests can be controlled. In order to use only 30mg of pesticides. In practice, however, much more than 3,000 times more pesticides have to be used (Brown 1951).

The hazards of general application pesticides are not just the active ingredients of pesticides. Most pesticide active ingredients are greasy and insoluble in water. Therefore, emulsifiers must be used for dilution in water, and use of 6-7 types of adjuvant which is never beneficial to the human body or environment, such as surface tension remover to reduce the surface tension of water, moisturizer and dispersant to prevent evaporation, and other fixing agents and electrodeposition agents. It is essential.

In recent years, natural pesticides that are less harmful to the environment have been developed one after another, and their use is increasing. However, these natural pesticides are expensive and mostly greasey, and they are synthetic chemicals to effectively spray small amounts of active ingredients onto large packages. Auxiliaries such as emulsifiers that are harmful to humans and the environment are used.

In addition, a lot of water used for spraying pesticides results in an increase in humidity in a closed greenhouse, causing the occurrence of fungal diseases due to high humidity when spraying insecticides. Therefore, in order to prevent the occurrence of fungal diseases, disinfectants are added to insecticides and sprayed. The spray particles sprayed through the nozzles have low control effects due to the gravity of the particles and the varying spray angles, making it difficult to reach the pests hiding in the leaf backs, stem gaps or facilities of the plants where the pests live.

In terms of economics, the equipment for spraying pesticides is expensive and there is a problem of acute pesticide poisoning for heavy labor and high concentration of toxic substances which are performed at high temperature and high humidity.

In order to improve such a problem, a smoking method for spreading an active ingredient into steam or smoke by heat is known. Such a method of smoking has the advantage of avoiding contact with pesticides and reducing labor loss without directly spraying pesticides.

In the conventional method of smoking, the active ingredient of the pesticide is ignited by using an oxidizing agent, a fuming agent, etc., when the combustion causes the active ingredient of the pesticide to evaporate. .

However, since the effective ingredient of the pesticide is encased in a large amount of smoke, the smoking method is effective, since most of the components of the smoke generated are easily evaporated as water vapor, and thus become gaseous before reaching the pest, thus losing much of the effect of contact and poisoning. There is a problem done.

Existing smokers are using a method of admixing the active ingredient of the pesticide with the active ingredient of the pesticide by generating a smoke by making the granules or some solid state by mixing the heating agent, fuming agent, etc. in the active ingredient of the pesticide.

The conventional solid or granular fumigant has problems such as destruction of active ingredient of pesticide due to rapid smoke and fire due to ignition, and it is manufactured by using nitrocellulose, which is a raw material of explosive, because of the risk of explosion and high price. There is a high cost disadvantage. In addition, there is a risk of exposing users to pesticides because of the inconvenience of having to install several in an enclosed space and the need for direct ignition.

And active ingredients of many pesticides are easily destroyed at high temperatures. These pesticides are not suitable for use as a conventional smoking method.

Conventional smokers are commercialized in the form of granules by mixing heat-generating agents and smoke-generating agents with active ingredients.They use nitrocellulose, the raw material of explosives, as a heat-generating agent, which may cause fire or explosion, and require careful handling in manufacturing, transportation, and storage. Do. In addition, even when a user uses a large amount of dozens (several places) in a large greenhouse in a large number of places to be ignited daily, there is a risk of pesticide poisoning.

In particular, accidents such as smoke and fire are often caused by carelessness or other matters. Therefore, the use of the smoker is not active due to the high manufacturing cost, inconvenience in use that must be directly ignited daily, and consequent difficulties in handling the risk of pesticide poisoning.

Smokers used in Korea are granular and use expensive materials such as nitrocell lurose and melamine as heat generators, and use aluminum foil to contain materials and ignition wicks are needed for the ignition of smokers. .

Pesticide spraying method is a method of heating by mixing the active ingredient of the pesticide and the blowing agent, but the azodicarbonamide component, which is mainly used as a blowing agent, generates a strong acid gas during foaming to rust various metal devices and to prevent the vinyl coating of the facility. The use of greenhouses is not suitable due to the shortened lifespan.

The present invention is to solve the problems of the conventional fumigated pesticides that have been used for pest control and the problems that did not achieve a satisfactory control effect due to the technical immaturity of the fumigation, fumigation control and a device for performing the pesticides As a technical problem to be achieved by the present invention, the fumigation and the fumigant of the present invention are intended to simultaneously apply natural products relatively safe to the human body as well as general pesticides as fumigation and fumigation. The purpose can be achieved by heating the dilution-produced liquid smoker using a heating device.

The fumigation, fumigating aid of the present invention is made by diluting an oxidizing agent, a fuming agent and a combustion rate regulator in water at a certain ratio. The user can then add commercial pesticides or other plant extracts and then heat them using a heating device to achieve the goal.

The present invention is to improve the disadvantages of the conventional smoker is limited in use due to the excessive cost, risk and inconvenience of manufacturing, while having the advantages of controlling the pollution and less soil than spraying pesticides.

Dissolve in water by mixing oxidizing agent, combustion rate control agent, and fuming agent, add active ingredient, put liquid smoke agent in heating bowl, and heat it for a certain time. At this time, with the evaporation of water, the active ingredient of the low boiling point pesticide is not destroyed, but is evaporated with some water to exert a fumigation effect. At this time, due to the latent heat of evaporation of water, the temperature of the liquid does not rise above 100 ° C., so that the active ingredient of the pesticide is not exposed to high heat. After all the water evaporates, the temperature rises, and when the boiling point of the circulator, the smoke, reaches the boiling point, the active ingredient with low boiling point evaporates again. When the temperature continues to rise and reaches the decomposition temperature of the oxidant, the oxidant starts to decompose and react with the circulating gas, generating a large amount of smoke. At this time, the active ingredient of the pesticide is also entrapped and volatilized to diffuse throughout the greenhouse. As it combines with the active ingredient particles in a gaseous state previously evaporated and suspended in a space, a high control effect is exerted.

Therefore, the effect of the present invention is that the active ingredient of a relatively low boiling point pesticide evaporates in the process of evaporation of water and boiling of the circulator, the smoke, exerts a fumigating effect and reaches the decomposition temperature of the oxidant after all the water evaporates If the oxidant is decomposed by the high-temperature smoke generated by the active ingredient of the pesticide evaporate to exert an effect in a smoked state.

Another advantage of the present invention is that as the water boils completely dissolves the oxidant, which is sufficiently mixed with the combustion rate control agent and the circulator, which is a fuming agent, does not cause the oxidant to flock and also fires due to the presence of some water during decomposition. It is very safe because no phenomenon such as fire occurs.

The active ingredient of the pesticide evaporated with water at a relatively low temperature before the decomposition of the oxidant is suspended in the air in a gaseous state, and some of them exert a fumigation effect on the target pest, and the gas particles of the active ingredient floating in the remaining air. After a while, the smoke is decomposed by a large amount of smoke generated by the decomposition of the toxic effect to obtain the effect of the contact poison.

As the present invention can obtain the fumigation and the smoke effect at the same time step by step in this way, the control effect is high

As another example of the present invention can be effectively used environmentally friendly pesticides used a lot recently.

Recently, plant essential oils and extracts have been widely used in pest control. However, the use of plant extracts is very high, so its use is limited. This is due to the fact that the plant parts for extracting the active ingredient are inexpensive and the cost of extraction is much higher. The present invention has the advantage that can be used at the same time as the active ingredient and the fuming agent in the relatively low-cost plant portion containing the active ingredient.

In order to extract the plant extract from the plant, various extraction methods are used depending on the type of plant. Hot steam, dimensional method, solvent extraction, etc. are widely used extraction methods. However, using this extraction method is expensive and polluting the environment because the solvent used and the by-products of the plant after extraction are left in large quantities in the form of garbage.

The present invention can be used as it is by milling dry plant parts containing the active ingredient without extraction process.

For example, ethanol extracts from corn leaves have been shown to have a protective effect on gray mold. However, in order to extract the active ingredient from the corn leaves, a large amount of ethanol is used to precipitate for a long time and then filtered to remove the ethanol to obtain the active ingredient. In this complex extraction process, a large amount of ethanol is used and it is expensive to remove and purify it again.

This outbreak can only be used after drying and grinding ground parts of plants containing active ingredients or by selecting appropriate substances such as ethanol, methanol, other solvents or water according to the plant components, and then putting the ground plants in a suitable container and mixing them for a certain period of time. After that, the dilution with the fumigation fume aid solution prepared in a suitable ratio is used as it is.

When the plant leachate and the fumigation aid are heated, the effective boiling point with relatively low boiling point evaporates with a certain amount of the boiling point extraction solution, such as alcohol or solvent, to exert a fumigation effect. The smoke is evaporated along with the smoke effect.

Therefore, it is possible to use only a simple procedure of drying and pulverizing an active ingredient-containing plant or dipping it in a solvent such as solvent, thereby reducing the expensive equipment and removal cost used to remove the used extraction solvent. It is possible to purchase various parts of plants that have been proven to be effective at low prices or to be used after being crushed and collected in nature, thereby widening the selection of drugs.

An object of the present invention is to improve the disadvantages of the conventional smoker, oxidizing agent, smoke, and combustion rate control agent by dissolving in water at a certain ratio according to the active ingredient of the pesticide, mixed with the active ingredient of the pesticide, fumigation fume To provide.

Still another object of the present invention is to provide a safe and easy-to-use smoking agent during production, distribution and storage by mixing with an oxidizing agent and a ignition inhibitor and the like without using an exothermic agent nitrocellulose which may cause an explosion.

Still another object of the present invention is to enable environmentally friendly pest control by purchasing or grinding parts of plants containing active ingredients and pulverizing them in nature and then leaching them in a solvent.

Another object of the present invention is to use the automatic fumigation fume control means as a device for effectively controlling the fumigation fume is divided into distributed installation natural convection diffusion type and central installation forced diffusion type.

By fumigation and fumigant of the present invention without human resident can be controlled automatically at night when the greenhouse is closed by the user to install the device, ignition, fire or not, etc. It is to solve problems such as worker exposure to pesticides.

1. Fumigation fume composition of the present invention

The present invention tends to evaporate easily because the particle diameter of a large amount of smoke and the active ingredient of the pesticide generated as the oxidant is decomposed is very small and less than 1 μm. Once the active ingredient evaporates, the effect as a contact poison becomes difficult to expect.

Therefore, it is important to prevent the active ingredient of the volatilized pesticides from being wrapped in a large amount of smoke (steam) to evaporate.

As a method for preventing the evaporation of the active ingredient as a plant extract or other waxy substance made of waxy substance having a very high evaporation temperature, there is no fear of being harmful to the plant, and it has an appetite suppression system and a repellent property of insects and pests. Can be used together.

As a representative example, Nim or Jojoba oil is widely used as a pesticide and repellent against various pests. However, when the oil is sprayed onto the surface of the plant as a waxy substance, the sprayed components do not evaporate and thus block the pores of the plant, which often causes weakening of the plant's transpiration. Therefore, it is preferable to spray neem oil in ultrafine state, but it is impossible to spread waxy substance in ultrafine state (Anand Prakash, 1997).

The present invention is an oil self-effect by using the plant leach or other pesticides, bactericidal, repellent, appetite suppressant effect such as nim oil or jojoba oil alone or in combination with common pesticides or plant extracts in the fumigant of the present invention In addition, it is possible to increase the effectiveness of other active ingredients, and by inhibiting and delaying the evaporation of the vaporized active ingredient, that is, vapor or smoke, has the advantage of simultaneously obtaining the insecticidal, sterilizing, repelling effect.

In the present invention, the oxidizing agent is chlorite, chlorate, perchlorate, nitrite, nitrate, which are organic or inorganic oxides that can be decomposed at a certain temperature to generate oxygen, such as NaClO2, NaClO3, NaClO4, NaNO2, NaNO3, KClO3, KClO4. , KNO2, KNO3 and the like can be used. Of these, high solubility in water and stable chlorate (NaClO 3) is preferred. These oxidizing agents can be used individually or in mixture of 2 or more types.

In the present invention, if you want to smoke pesticides in the form of emulsions or hydrates formulations that are commercially available pesticides, sorbitol may be used as a sucrose. In this case, since the reaction with the oxidant is made violently, ammonium chloride or other burn rate regulators may be used as the burn rate regulator. In consideration of solubility with water, it is preferable to use ammonium chloride or guanidine sulfamic acid.

In the mixing ratio of oxidizing agent, fuming agent and burn rate ablation. It may vary depending on the active ingredient of the pesticide, the ratio of the active ingredient and the oxidizing agent of the pesticide is a weight ratio of 1: 0.3-50, preferably 1: 0.5-30.

The ratio of oxidant and burn rate abatement also depends on the characteristics of the active ingredient of the pesticide, 1: 1 to 0.1, preferably 1: 0.1 to 1.5.

The ratio of the oxidizer and the smoker's citrose is also dependent on the active ingredient of the pesticide 1: 0.1-15, preferably 1; 0.3-5.0 are preferred.

2. Example configuration and effect of fumigation of fumigation fume composition according to the present invention

The method of fumigation of the fumigation fume composition of the present invention may be divided into a distributed installation natural convection diffusion type and a central installation forced diffusion type using a fumigation smoker and a blower.

The fumigation method of the present invention enables the user to control the fumigation fume composition of the present invention automatically at night in a closed greenhouse without a person resident, such as installation, ignition, confirmation of ignition, etc. In order to solve the problems caused by the need to be directly, that is, unprotected exposure to pesticides during the preparation, ignition, and verification process Looking at the configuration of the present invention automatic fumigation fume means fumigation fume (100) ) Is the casing 110 and the heating plate 130 is fixed to the bottom of the fumigation fume composition heating container 120 and the fumigation fume composition heating container 120 is configured to be accommodated on the casing 110 and the top. The heater 140 is fixed to the bottom surface of the heating plate 130 and a wire 150 for supplying energy to the heater 140 is provided.

In the figure (160) shows the fumigation fume composition of the present invention.

Dispersion installation natural convection diffusion method by the method of fumigation fumigating composition of the present invention by distributing the fumigation fume 100 properly in the control area as shown in Figure 2 a number of fumigation fumes 100 at regular intervals Arrangement is installed and connected to the electricity supply line 200, the electricity supply line 200 is configured to be provided with a timer 210 that automatically adjusts the heating time and control time.

In the present invention of the fumigation smoking apparatus, the central installation forced diffusion type is equipped with a blower 300 on the upper portion of the fumigation fume composition heating container 120 of the fumigation fume 100 and the fumigation fume composition is heated A plurality of active ingredient pressure pipes 310 are provided to pressurize and discharge the generated active ingredient, and a plurality of active ingredient discharge holes 320 are perforated in the active ingredient pressure pipe. The active ingredient discharge hole 320 is configured to gradually increase the diameter away from the blower 300 or to configure the interval of the active ingredient discharge hole 320 of the same diameter gradually away from the blower 300 .

The blower 300 is provided with a timer 330 which automatically adjusts the heating time of the fumigation smoker 100 and the driving time of the blower 300.

The fumigation fume composition heating vessel 120 is composed of a curved surface 121 in consideration of the improved thermal conductivity and thermal deformation and the top surface of the heating plate 130 curved surface 121 of the fumigation smoker heating vessel 120 The curved surface 131 is configured to be in close contact with each other.

Explain the effect of the above fumigation.

The fumigation fume of the present invention is the fumigation fume 100 to perform the fumigation fumes as a device for heating the fumigation fume composition obtained by the present invention to generate an active ingredient with steam and smoke fumigation fume is configured on the casing 110 When a predetermined amount of fumigant 160 is put into the composition heating container 120 and electricity is supplied, the fumigant composition in the heating container 120 is heated while the heating plate 130 is heated to generate an active ingredient in a vapor or smoke state. .

In addition, the fumigation fume composite container 120 is the bottom surface is composed of a curved surface 121, the upper surface of the heating plate 130 is also composed of a curved surface 131, preventing deformation and heat conduction area due to high heat. This acts to enlarge.

In the present invention, the automatic fumigation fume dispersing installation is a natural convection diffusion type is to diffuse the active ingredient generated in the fumigated fire extinguishing material by the convection of the indoor control area.

In the present invention, the automatic fume fume apparatus installed in the central forced diffusion type is mounted through the blower 300 in the upper portion of the fumigator (100) by the effective blowing through the effective component pressure pipe (310) effective ingredient discharge hole (320) It can be discharged to obtain a rapid diffusion effect.

The reason that the diameter size of the effective ingredient discharge hole 320 drilled in the effective component pressure pipe 310 is gradually increased as the distance from the blower 300 increases, so that the blowing pressure generated in the blower 300 increases away from the blower. Because of the drop, the diameter of the effective ingredient discharge hole 320 is reduced in the place close to the blower with strong blowing pressure, and the diameter of the effective ingredient discharge hole 320 is increased in the far away place from the blower having a weak blowing pressure. It is made uniform.

In addition, by moving closer to the distance between the effective component discharge hole 300 having the same direct hole punched in the effective component pressure-supply pipe (300) gradually closer to the blower 300, where the blowing pressure is strong and the blower (300) ), Even where the blowing pressure is weak, it is possible to evenly distribute the active ingredient.

The control method for fumigation of the fumigation fume composition of the present invention will be described in more detail.

The fumigation and smoking process of the plant dried compound having the active ingredient of the present invention is prepared by pulverizing the plant containing the active ingredient to be pulverized and then crushed and then used or sealed in a container with a solvent for extracting the active ingredient of the plant. Then, stored at room temperature for 1 to 3 days, mixed with a fume auxiliary agent at a certain ratio, and then put into a fume fume composition heating container of a heating fume, and gradually heated when the power is applied, mixed with an active ingredient of a plant extract, fumigation, and a fume auxiliary agent. As the temperature rises, the relatively low boiling point volatile solvent first evaporates. At this time, the low boiling point components of the active ingredient is also evaporated to exert a fumigation effect. At this time, the temperature of the solution does not increase due to the latent heat of evaporation of the solvent, but after the solvent has completely evaporated, the temperature of the solution rises again to increase the evaporation temperature of the water mixed with the fumigant and the water evaporates. The volatile active ingredients with evaporation will also evaporate and exert a fumigation effect. Due to the latent heat of evaporation of water, the temperature of the solution does not rise above the evaporation temperature of the water. However, after the water has evaporated completely, the temperature rises. At this time, the active ingredient having a high boiling point is evaporated by the circulating component, which is a fuming agent included in the fumigation and smoking aid. Exert a fumigation effect. Afterwards, the circulator, the smoker, does not evaporate well, so the temperature continues to rise, and when the decomposition temperature of the oxidant is reached, the oxidant starts to decompose and reacts strongly with the circulator and starts a rapid combustion. However, since the rapid combustion does not generate smoke, a combustion retardant is used to prevent such a rapid combustion and generate a large amount of smoke. Therefore, a large amount of smoke is generated, and the remaining active ingredient is surrounded by evaporated smoke by high temperature and spreads, thereby exerting a smoking effect.

As described above, the fumigation fume composition and the adjuvant of the present invention have the advantage of being more safe and widely available active ingredients of pesticides than the conventional fume.

The fumigation fume composition and auxiliary of the present invention are in a liquid state containing water, unlike the general fumigant, so there is no risk of ignition during combustion due to decomposition of the oxidant. It is possible to maximize the control effect of pests because it is possible to achieve the best smoking rate by adjusting the

Fumigation rate of the fumigated active ingredient of the present invention is to smoke the waxy natural plant extracts with high evaporation temperature with the active ingredient in order to overcome the disadvantage that the fumigated active ingredient is easily evaporated to lose the efficacy. By lowering the effective ingredient can exert the effect as a contact poison instead of gas poisoning can obtain a high pest control effect

Is easy

The fumigation fume composition and the auxiliary of the present invention do not use nitrocellulose, which is a raw material for a conventional fume, so that the risk of explosion and fire possessed by nitrocellulose can be excluded, and thus safety is high in manufacturing and use processes.

If the effective ingredient is diffused more extensively by the blower pressure of the blower, the control effect is more excellent, and the timer is installed so that the control time can be arbitrarily controlled. As a result, the control effect can be further improved.

In the case of the active ingredient of the pesticide pesticides with some fumigation effect, as in the experimental example above, the control value was much higher than the general fume effect. On the other hand, in the present invention, water and sucrose components of the fumigation and fumigating aids are easily evaporated together with water at low temperature without destroying the drug, and thus remain in the air. This is because it acts on phosphorus pests to exert its effect.

In addition, the control value was higher compared to the spray type diluted with water and sprayed. This is because during the daytime when the temperature of the greenhouse is mainly spraying pesticides, the active ingredient of some pesticides having a fumigating effect is evaporated by the high temperature due to the very high temperature and direct sunlight, and fled to the outside by ventilation or decomposed by the direct sunlight.

On the contrary, the fumigation and the fumigation of the present invention are effective in the enclosed space because the active ingredient is not destroyed by direct sunlight and the ventilation window is closed because the active ingredient is evaporated at night time without direct sunlight and is not ventilated. Is high.

When the general synthetic pesticides and plant extracts are fumigation and smoked together against the pests that are resistant to general pesticides, the effect is increased. According to a recent Journal of Vector Ecology, pesticides of Aedes degypti mosquitoes and Culex annulirostris mosquitoes were much more effective when mixed with general insecticides and plant extracts. In particular, research on mosquitoes resistant to general insecticides has been conducted. The mixed use of general pesticides and plant extracts against pests caused by indiscriminate use of pesticides has the effect that plant extracts act as a potentiator of general pesticides. Therefore, it is preferable to use a plant extract or a plant mill containing an active ingredient as a general pesticide, fumigation, and smoking aid.

When using a plant mill containing an active ingredient, a significant amount of starch is included depending on the type of plant, so the amount of starch in the supplement should be replaced or subtracted.
