Description

A vermin controlling composition with natural substances

The present invention relates to a natural material composition containing a pest repellent, and more particularly to a pest repellent having a pest protection effect for protecting livestock from mosquitoes, which are harmful insects (hereinafter, pests) that mediate various diseases. It relates to a composition contained in.

Diseases caused by mosquitoes in livestock include dog heartworm infections in dogs, getavirus infections that infect not only mammals such as pigs, horses, and cows, but also bovine epidemic fever (BEF), which occurs mainly in cattle. It is known to be a major disease such as Akabane disease, Ibaraki disease, Chuzan disease, terrestrial stratum, and Newcastle disease occurring in birds such as chickens and ducks.

In addition, as a general preparation for pests, conventional spray insecticides are used the most, and fragrance-based and electronic heating methods have been used. However, the conventional method of using pesticides has a destructive effect on the environment, and in advanced countries, the use of pesticides has already been suppressed.In the case of incense, there is a risk of fire, and in the case of electronic mosquito incense, the power is always turned off. As a result, there is a problem in use, such that it is inefficient to apply to livestock, and the insects exposed to pests have a weak insect repelling or repelling effect. Significant damage is inflicted.

It was developed to solve the above problems, and it is a natural substance that has been proved to be safe for humans and livestock, and it is a material that exhibits pest repelling effect against mosquitoes that mediate various diseases such as paper, rice husk, rice straw, barley, sawdust, leaves, It is an object of the present invention to provide a natural material composition containing a pest repellent agent that can be efficiently installed in the rearing space of livestock to protect the livestock from pests.

The natural material composition containing the pest repellent of the present invention for achieving the above object contains a natural material and a pest repellent exhibiting the pest repellent effect. The pest repellent is contained in a proportion of 1 to 80% by weight, preferably 2 to 50% by weight, more preferably 10 to 40% by weight of the total content of the nano- or microcapsule-type solids. In addition, the pest repellent is formed by mixing or spraying on the natural material to the pest repellent material contained in the natural material, and drying the composition.

The implementation method of the natural material composition containing the pest repellent of the present invention for achieving the above object provides the following implementation characteristics.

Prior to describing the preferred embodiments of the present invention in detail, the present invention is not limited to the particular details disclosed. The limitations with respect to the particular implementations published are not intended or inferred. Although the invention has been disclosed in connection with the preferred embodiment, it is evident that various modifications and changes are one of the techniques, and the results will appear within the scope of the invention. Also, the terminology used herein is for the purpose of description and not limitation.

In order to describe in more detail the natural material composition containing the pest repellents disclosed herein, the following definitions will be used.

“A domestic animal” in this specification (and claims) refers to animals and birds that are useful for human life in which humans are purely and improved wild animals and breed freely under human protection. "What is useful here is not only the production of livestock products such as milk, meat, eggs, hair, leather, feathers, and the like, but also the use of power in ministry, as well as pets for appreciation of their appearance, actions, and sounds. Donkeys, cows, buffalo, sheep, goats, camels, reindeer, pigs, dogs, cats and rabbits. Birds include: chickens, turkeys, geese, ducks, septic tanks, pigeons, and quails.

“Injurious insects” in this specification (and claims) generally refer to mosquitoes or flies as insects that directly or indirectly harm human and livestock life. "

In addition, the detailed description of the natural materials and pest repellents used in the present invention are as follows.

The natural materials used in the present invention are conventional paper processed using chaff, rice straw, barley, sawdust, leaves, hay and bark obtained from nature. These natural materials may be used alone or in combination of one or more.

For the paper, it is preferable to use printed matter, packaging paper, etc., which have been used for commercial purposes, because the purpose of the present invention is used for livestock, but good-quality paper (art paper, imitation paper, etc.), which is a non-recycled ordinary material, is used as various printed matter. Papers, papers, newspapers, pulp paper, and other papers such as paper, paper, manila paper, and kraft paper can be used.

In addition, it is difficult to contain pest repellents by mixing or spraying with vinyl or resin among printed matters and packaging papers used in the commercial market, or it is toxic to bacterial infections and printed matters, making it difficult to use in the livestock industry. It is not preferable to use what is present as a component of the present invention.

In addition, the natural material used in the present invention can be used without limitation as long as it is a natural material that does not interfere with the object of the present invention other than the paper, chaff, rice straw, barley, sawdust, leaves, hay.

In addition, natural materials such as paper, rice husk, rice straw, barley, sawdust, leaves, and hay used as components of the present invention include, for example, general sterilization methods; It is preferable to use a sterilized and dried by a method such as high temperature, high frequency, infrared rays, etc., and may be added to the sterilizing agent for the purpose of sterilizing the bacteria in the preparation of the composition. At this time, the fungicide should of course be added so as not to obstruct the purpose of the present invention.

In addition, pest repellents are an alternative to insecticides that can effectively protect humans from pests, using natural materials developed as a new concept as pest control agents, which can prevent insect-borne diseases on the human body and cause side effects such as environmental pollution. There is no attention.

Essential requirements for pest repellents to be used in the present invention are harmless to humans and livestock, long lasting effect, no irritation to skin, no unpleasant odor, chemically stable, full skin It will be effective even if it is not processed. Therefore, in the present specification (and claims), 'pest repellent' is an harmful pest that mediates various diseases to humans or livestock, and it is effective to eradicate insects such as flies and mosquitoes, inhibit access, and prevent activity. Natural substances or compounds that exhibit insect repelling and repelling effects or escape.

Citronella essential oils extracted from the leaves of PELAR GONIUN CITROSA, known as grasses that chase mosquitoes that mediate various diseases in the human body, meet the above requirements and are not regulated by the US Environmental Protection Agency (EPA). It is harmless to the human body as it is classified as a non-toxic substance, has no side effects, and can be used by children. In addition to chasing mosquitoes, Citronella is also effective in relieving muscle spasms, removing oily skin, removing impurities from the skin, disinfecting the skin, and refreshing and clearing convergence.

In addition, the pest repellent (PMD) derived from Eucalyptus is a oil extracted from lemon eucalyptus plants in China, which is not as effective as N, N -diethyl- m -toluamide. It has been shown to be effective against ticks, flies, and mosquitoes, to reduce coughing, antiviral effects, bronchitis, asthma, phlegm, and flu.

In addition, the pest-avoiding plants reported so far are essential oils extracted from neem oil, Lantana camara , Artemisia vulgaris , rose, geranium, and lavender, and Korean Publication No. 2003-0083631. Fennel oil, fenchon ((+)-fenchone), and octadecenoic acid ((E) -9-octadecenoic acid) extracted from fennel are known. It is also a compound contained in plants such as terpenes, phenols and alkaloids (Harbourne, JB 1993.Introduction to Ecological Biochemistry, 4th Ed.Academic Press, New York) as a secondary metabolite. The method is simple and effective for limited pests such as pest evasion purposes and does not affect natural enemies (Jacobson, M. and Crosby, DG 1971. Naturally Occurring Insecticides.Marcel Decker, New York; Elliot, M. 1977. Synthetic pyrethroids, pp 1-28, in M. Eliott (ed.) Synthetic Pyrethroids.ACS Symp.No. 42, Amer.Chem.Soc ., San Francisco, CA; Hedin, PA 1982.J. Agric.Food Chem . 30: 201-215; Arnason, JT, Philogene, BJ, and Morand, P. 1989. ACS Symp. Ser.No. 387, Amer. Chem. Soc ., Wachington, DC, 1989; Isman, MB 1995. Rev. Pestic. Toxicol. 3: 1-20.), Has been recognized as an alternative to pesticides.

As described above, by encapsulating a natural material (or natural medicine) which is harmless to humans and livestock and is effective as a pest repellent in small particles of nano or micro units, the capsule is encapsulated as a polymer material having a dense and uniform distribution. In addition to protecting the internal substances that are insect repellents by the walls of the capsules, it is possible to freely control the timing, location, and release rate of the natural medicines inside the capsules by changing the material and thickness of the materials forming the walls of the capsules. By utilizing the characteristics, it is possible to obtain an environmentally friendly product that can give a long-lasting pest avoidance effect. Generally, a nanocapsule is a process of completely enclosing small particles or liquid droplets in a membrane, and inserting a substance into a container made of a polymer having a diameter of several nm to several hundred nm. Nanoparticles and microparticles are classified based on particle size. Particles in the range of 10 to 1000 nm are called 'nanoparticles', and particles having a size of 1 to 1000 μm are commonly referred to as 'micro particles'. The microparticles, that is, microcapsules, are more easily destroyed than nanoparticles in size, and the release rate is not easily controlled due to over-release of the material, whereas the nanocapsules are relatively small in particle size, thus overcoming the above problems. In addition, the polymer material of the inner wall is a quantized molecule, and the physical properties are greatly improved compared to the properties of the bulk material. It is known from the Republic of Korea Patent No. 2003-0067354 "Natural capsules carrying natural flavor and a method of manufacturing the same", the technology related to these nanocapsules means that the pest repellent used in the present invention can be nanoencapsulated do. Nanocapsules carrying the natural fragrance are in the preparation stage for commercialization, and microcapsules as capsule-type pest repellents have been commercialized, and the use of these materials has been expanded in the field of fibers and household goods.

Such pest repellents can be used in the present invention products developed for the purpose of repelling and combating pests such as mosquitoes in the microcapsule type insect repellent material of Banwol Industrial Complex, Choji-dong, Ansan-si, Gyeonggi-do, Korea.

However, the above-mentioned capsule-type pest repellents are merely listed as an example, and the pest repellents used in the present invention are contained in natural materials such as paper, rice husk, rice straw, barley, sawdust, leaves, hay, etc. Any material exhibiting properties can be used without limitation, and it will be understood by those skilled in the art that the product can be properly selected from various commercially available pest repellents or, if necessary, can be used to purchase a product.

In addition, it is apparent that the present invention may contain one or more of the above encapsulated pest repellent components or one or more of the non-encapsulated non-encapsulated pest repellent components.

In addition, the pest repellent contained in the composition of the present invention has a nano or microcapsule-based solid content based on 1 to 80% by weight, preferably 2 to 50% by weight, more preferably 10 to 40% by weight of the total weight of the natural material. Within the range, the components of pest avoidant should be appropriately determined according to the amount of livestock and breeding space for each animal or bird, the range of pest distribution, and the composition or form of the composition.

The preferred content of the pest repellent is too high to suggest that the composition formulation is difficult to use in livestock, or a small amount that is not enough to achieve the object of the invention may be undesirable.

In addition, insecticides, house dust mites and insect repellent microcapsules (HunterBall, for example, products made by Polychrome), solvents (alcohol, etc.), which have been proven to be stable to humans and livestock, as well as house dust mites and moths, may be used as necessary. It can be used as an additive without disturbing.

The present invention exhibits excellent insect repellent and repelling effects that can safely protect livestock from pests by mixing each material with one or more materials, preferably by mixing pest repellents or by a method such as spraying and drying. It is to provide a natural material composition containing the pest repellent of.

The mixing method may be a general method, that is, a method of mixing the material in the mixer to mix well or by hand mixing, etc. Also, as a method of spraying, for example, a sprayer or If it is a method which implements this invention preferably, such as the method of spraying with a spray gun etc. provided with a compressor etc., or the method of spraying and mixing with a special spreader and a mixer, it will be used without limitation.

The drying method is not limited to those capable of achieving the object of the present invention as a method of evaporating moisture, and generally used are dryers, tunnel dryers, heat and hot air dryers, and natural drying using infrared or high frequency. There is this.

Hereinafter, the present invention will be described in more detail through Examples and Experimental Examples. However, the technical scope of the present invention is not limited to these, and the pest repellent content in these examples is, unless specifically determined, the weight percentage of the entire system in which the components thereof are blended.

Experimental Example: Evaluation of the pest repellent effect of natural material composition containing pest repellent

Table 2 is a place where the target group of Table 2 is raised by installing the composition prepared in the above example in a livestock breeding space, that is, a barn for about 2.5 months from mid-July to the end of September, when mosquitoes and other pests are most active. Experimental evaluation indicating that the distribution of pests was visually identified and evaluated.

At this time, the composition is dry within the barn within the range in which the target group is active, or the thickness of about 3 to 10 cm on the floor with a humidity of 65 ~ 90 ° F to step directly on the subject or sleep on the composition. The natural state was maintained without any restriction on the back activity.

In addition, the space where the target group is raised is a place that is not normally sealed in the form of a barn or a house, and it is defenseless from pests, and especially at night when mosquitoes are active, it is considered to be a serious place to raise the target group without using insect repellents. This is where it becomes.

As shown in the experimental example using the composition of the present invention of Table 3, there are a large number of evaluation target groups in the barn (breeding space) to increase the temperature in the barn by the body temperature of the livestock, or the composition of the livestock is bright or its When there is a lot of physical contact with the composition, such as sleeping on the stomach, the capsule that protects the pest repellent, ie, the coating, ruptures, releasing the substance of the pest repellent, preventing the access of mosquitoes, causing diarrhea to die, or inhibiting activity. The mosquitoes showed no or almost reduced mosquitoes in the vicinity of the target group where the natural ingredients containing pest repellents were installed, and the distance from the composition was large. In areas where pest repellents are not within reach, mosquitoes are concentrated to try to reach the target population. It could be full.

Of course, a small number of mosquitoes around the livestock were also very active due to pest repellents, making it difficult to harm them.

Therefore, natural ingredients containing pest repellents were evaluated to have excellent insect repelling and repelling effects to protect livestock from pests such as mosquitoes.

In addition, the time and number of exchange of the composition during the experiment period is different depending on the subject group, but only at least once every three to 15 days intervals that the composition is deteriorated by animal waste (feces, urine). In addition, the composition that consumed the pest avoiding substance was replaced with another composition that was not exhausted. The composition of the insect repellent containing less content Formula 1 is replaced more frequently than the formulations 2 to 4, so that the livestock frequently loses dirt (feces and urine). It is considered that it is economical to use a composition with a low content of pest repellents such as silver formulation 1, and to use a composition containing a high content of pest repellents for the parts free of dirt.

In addition, the natural material composition containing the pest repellent did not find any adverse effects such as skin irritation and unusual skin irritation of the test subjects, even after physical contact with the composition during the experiment, and did not show any problem even after the experiment.

As described above, in the pest avoidance experiment by the natural material composition containing the pest repellent completed by the above-described technology of the present invention, the higher the content of the pest repellent as evaluated above, the better the insect repellent effect, and the microcapsule-type pest Since the repellent is preferably installed and used in places where the physical contact of the livestock is large, and where the body temperature of the livestock can be transmitted, the effective life span of the pest repellent is continuously maintained for a long time, and thus the repellent effect against the pest is excellent. In addition, the material is an environmentally friendly natural material such as paper, rice husk, rice straw, barley, sawdust, leaves, hay, etc., and it is a material that natural livestock makes contact with the livestock. It is useful in the livestock industry as a means to safely protect livestock from pests.

As described above, the natural material composition containing the insect repellent of the present invention includes a pest repellent in natural materials such as paper, rice husk, rice straw, barley, sawdust, leaves, and hay, and is placed on the bottom of the livestock breeding space. It is easy to install and releases pest repellents, so that the insect pests or avoiding natural pests harmful to the livestock are continuously and effectively protecting the livestock from pests. In addition, the natural material composition containing the pest repellent used in the rearing space of the livestock is used for plant compost, so that the pest repellent material remaining in the composition is less entangled by the release of the pest repellent material, which is useful for crops (plants). Many effects can be provided, such as reducing the damage from pests.
