Description

FIELD OF THE INVENTION The present invention relates to a granular composition for controlling harmful substances in a soil containing plant extracts and minerals,

The present invention relates to a composition for controlling granular plant extracts and minerals, and more particularly, to a composition for controlling harmful animals in soil using a plant extract and mineral degradability, soil permeability and durability, Granular compositions and methods of use thereof.

Several factors are involved in determining the crop cultivation environment, among which are the activity and growth of the soil-pest animals that affect the soil environment and the rhizosphere of crops, and the food chain relationship. In particular, the most important biological factors are soil noxious animals that live in the soil and contain the pests that cause crop damage to cause direct damage and indirect illness as well as disgust. The habitat and breeding of these harmful animals are affected by environmental factors such as physiological factors and ecological factors related to feeding activities and crop cultivation methods in the ecosystem.

The harmful animals that live in the soil space in which the crops or various plants grow are those of the species such as the grubs, the insectivorous insects, the spider mites, the flea beetles, the vertebrates, the small roots flies, the earthworms, the snails, the leeches, And it mainly affects the topsoil or soils and has harmful effects on crop growth.

Because of the stress stimulation inside and outside of various kinds of soil harmful animals, the crops are finally damaged due to direct damage such as nutrition deodorization, growth inhibition, and pathogenic infection.

Soil harmful animals have a negative aspect to human activity, but they can not be artificially easily removed from the viewpoint of ecosystem maintenance, and it is a life that can not be done. However, when more harmful animals are inhabited and breed more than necessary, yields of crops and yields are decreased. Also, as the number of people enjoying outdoor activities increases due to the increase of leisure population, The demand to prevent was increased.

In response to such demands, substances having inhibitory activity such as plant extracts such as tea plants or residues containing them have been used as products of environmentally friendly organic materials and functional fertilizers, but most of them have been developed as liquid type formulations It can be easily lost during the treatment, and the effect thereof fluctuates greatly, which is inconvenient for handling in local treatment. The reason for this is that since the harmful animals inhabit in the soil or in the soil, the granular sustained products represented by the ball type granules, in which the effective components slowly dissolve and are effective, are suitable.

In recent years, there has been a growing public interest in health, hygiene, environment and safety. In the field of eco-friendly materials, it is being developed in various ways using natural materials derived from such plants. Accordingly, functional fertilizers and eco-friendly materials utilizing natural extracts having superior performance to existing natural products have been developed.

Conventionally effective plant-derived natural products have been conventionally weighed, mixed, and simply dissolved to adopt a method of commercializing them in a liquid phase. As an example, Korean Patent No. 10-0852398 discloses a composition containing a plant extract and a method of controlling the same. As for the preparation method of the ball type, Korean Patent No. 10-1306934 discloses a limited technique for forming a composition for a porous ceramic ball and a method of producing it, which does not have a biological activity function.

In recent years, preference for rehabilitation formulas due to the decrease in labor force has increased, steady increase of harmful animals in soil due to increase of organic material input, increase of facility cultivation area, increase of grass plant area such as parks and schools as well as golf course, There has been a continuing demand for the development of bioactive formulations using environmentally friendly substances.

However, the production method of forming into the ball type granular phase is not limited to the characteristics of the raw materials cured by moisture in the atmosphere, the conditions of the heat treatment for determining the degree of collapse, the particle size of the raw materials and the raw materials, the rotation speed for seeding and molding, The amount of injection of the fuel is required to satisfy all of the basic conditions. In order to solve this problem, it is necessary to develop the technique in parallel with the method of dissolving the raw material and injecting it or injecting the raw material directly.

The ball molding products used for existing health, water, building materials, etc. are controlled by the amount of water spray and method on the material composed only of the mineral combination, but when the plant extract material is input, the condition suitable for the characteristic should be optimized. In addition, the ball-type granule is a typical sustained-granule granule product, which has been applied in various industries, but no case has yet been developed as a composition for controlling composition containing plant extracts.

The object of the present invention is to provide a granular composition for the control of soil harmful animals and a process for producing the same, which comprises a plant extract and a mineral substance, which are active ingredients for effectively controlling soil-pest animals and increasing crop growth, Method.

It is another object of the present invention to provide a sustained-release formulation for sustained release of a sustained-release formulation at a constant release rate and a sustained-release formulation using an eco-friendly substance and a plant extract and a mineral substance as an active ingredient, And a method for producing the granular composition for controlling soil harmful animals, which method comprises the steps of:

It is a further object of the present invention to provide a granular soil-controlling composition which is easy to use in soil and which is capable of slowly releasing the active ingredient at a constant release rate for a long period of time to stably control soil- And a method for controlling the same.

An example of the present invention is a plant extract having saponin, wherein the active ingredient and the mineral matter contain the control particles adhered or impregnated to the mineral seed particles, and the control particles have a particle diameter of 1 mm to 5 mm. Based on the total weight of the composition.

DISCLOSURE OF THE INVENTION The inventors of the present invention have made efforts to develop environmentally friendly natural materials having excellent insecticidal effect and to produce stable environmentally friendly materials as ball type granular products, The present invention relates to a process for producing a granular composition for controlling harmful substances in a soil by molding an extractant, a mineral powder and a mineral seed, and subjecting the granules to heat treatment to form a granular composition. Physical strength and special functions are secured, and the disinfecting effect against harmful animals in the soil is excellent, and the disintegration property, soil permeability and durability in soil environment are found, and the present invention is completed.

Hereinafter, the present invention will be described in more detail.

An example of the present invention relates to a granular composition for soil-pest control, comprising an active ingredient of a plant extract containing saponin, and a controlling particle containing a mineral and a mineral seed particle.

Since the composition according to the present invention has a spherical granular structure, plant extracts and minerals must be well formed in the preparation step, and the release properties of the active ingredient should be satisfied when the active ingredient is slowly applied to the soil at a constant release rate. In addition, the active ingredient of the present invention is a plant extract, and unlike ordinary chemical control agents, it is excellent in environmental safety. Further, the composition according to the present invention has an advantage of being safe for organic farming, urban agriculture, and home gardening because it has a large amount of minerals and is excellent in soil modification effect for improving soil environment.

The plant extract applicable to the present invention can be used as long as it has a controlling activity against harmful animals on the surface of the soil or soil. Preferably, considering the controlling effect on the harmful animal of the soil and the release characteristic in the soil, Plant extracts can be used. For example, one or more plant extracts selected from the group consisting of camellia, yucca and quillaia can be used. The plant essential oil can be produced through ordinary extraction, distillation or compression.

The camellia and Camellia oleifera used for the extract of Camellia spp. Used in the present invention are widely distributed and widely cultivated in China and widely distributed at an altitude of 500 to 1,300 m. Saponin, a camellia plant extract, is a glucoside compound. It is a natural surfactant and widely used for chemicals, insecticides, beverages, agriculture, textiles, petroleum, mining, building materials, emulsifiers, detergents, pesticide additives and feed additives.

The oil used for the Yucca gloriosa extract used in the present invention is native to North America and is an evergreen tree planted in a garden or a greenhouse in the southern part of Korea. Diluent and other food additives can be added to preserves the quality of the material obtained by extracting Yucca root with water. It is a dark brown liquid with an unusual odor and contains saponin glycosides, which cause air bubbles when shaken with water. When added to soft drinks, cocktails, etc., the bubbles will be kept for a long time, and the bubbles will be bubbled at pH 2 ~ 10 and the bubbles will be stable. It also improves the environment of the housing by reducing ammonia production when added to the feed.

As used in the present invention, the quillaja used in the Quilajasaponaria extract is an evergreen arborescens of Rosaceae in Chile, Bolivia and Peru region of South America. It is a pale yellowish brown powder or liquid and has an irritating taste. The extract is obtained by extracting and purifying the bark of Quillaiasaponaria with water. The main component is saponin, the Qualylase skeleton is used as a hydrophilic group, and the sugar residue of the glycoside is used as a hydrophilic group. It dissolves in water and does not dissolve in fat. The pH of the 1% aqueous solution is 4.5-5.5 (powder). Qualia extract is an HLB surfactant which has a very high surface tension reduction effect, dissolves in water, and is highly hydrophilic. Especially, it is very stable because it is stable to heat, and the difference of emulsifying power according to pH is small. Diluents and other food additives may be added for the purpose of quality preservation.

The plant extract of the present invention may be prepared according to a conventional method for producing plant extracts, and examples thereof include, but are not limited to, a cold extraction method, a warm extraction method, a heat extraction method or a reflux extraction method. Examples of the plant extract include solvent extracts of the plant extract using at least one selected from the group consisting of water, alcohols having 1 to 4 carbon atoms, ethyl acetate and hexane as a solvent. When the extraction solvent is water, it may be subjected to hot water extraction, and in the case where the extraction solvent is alcohol, reflux extraction may be used. Further, the extract extracted with the solvent may be further subjected to extraction, followed by further fractionation with a solvent selected from the group consisting of hexane, methylene chloride, acetone, ethyl acetate, chloroform, and mixtures thereof. May be used alone or in combination. The extraction temperature may be 4 to 120 ° C, but is not limited thereto. The extracting time may be 10 minutes to 300 minutes, but is not limited thereto.

In a specific example of the present invention, the plant extract may be prepared by subjecting a plant to reflux by adding ethanol-diluted water, filtering the obtained extract by using a filter paper, concentrating it by vacuum decompression, and freeze-drying it.

The extraction site of the plant extract according to the present invention is not particularly limited and may be selected from a whole part of the selected plants or a part of plants selected from the group consisting of roots, stems, leaves, flesh, flowers, fruits, Lt; / RTI >

The extraction process may be performed using a conventional extraction apparatus, an ultrasonic pulverization extractor, or a fractionator, but is not limited thereto. The extract thus prepared can be concentrated by filtration under reduced pressure or by drying to remove the solvent. Both filtration under reduced pressure and drying can be carried out. The filtration under reduced pressure can be carried out by low-temperature decompression concentration using a reduced pressure concentrator, But it is not limited thereto.

The granular composition according to the present invention comprises spherical control particles comprising a mixture of mineral and plant extracts and mineral seed particles.

The spherical control particles including the plant extract according to the present invention are distinguished from the prefabricated or adsorbent granules of chemical pesticides. The prefabricated granule of chemical pesticide is prepared by mixing the raw material and the adjuvant, kneading it, pulling it with the granulator, drying it, and having the cylindrical shape. The adsorption type granule is made by adsorbing the raw material in the increasing amount and the auxiliary agent, and has a generally irregular shape. The spherical control particles of the present invention are manufactured into spheres of uniform particle size through friction while rotating the cylinder, and are easy to be applied to plants which are easy to spray and machine spray, and which grow on the ground like grass.

The controlling particles according to the present invention have a particle diameter of 1 mm to 5 mm, preferably 2 to 3 mm, and have a core-shell structure. The mineral seed particles used as a seed for preparing the controlling particles may have a diameter of 0.05 to 1 mm, preferably 0.1 to 0.5 mm.

First, a mineral powder is put into a rotating cylinder, and while spraying water, bead-shaped seed particles having a particle diameter of 0.1 mm to 0.2 mm are formed through rotation and friction. Thereafter, the seeds are rotated and a continuous mixture of plant extracts and minerals is added at the same time as the seeds are continuously supplied, so that the seeds are present in the interior and impregnated and adhered to the seeds of the plant extracts and minerals to form a core- .

The ball type can be applied regardless of the characteristics of the applied crop, and it is convenient to use such as direct spraying and machine spraying. Considering this, the particle diameter range of the control particles is selected. Conventional prefabricated, adsorbent granules and the like may generate fine powder during spraying and storage, which may adversely affect the user's health and environment.

The mixture of the raw mineral material and the plant extract used for producing the controlling particles may be a powder form or a liquid form, for example, a mixture of a plant extract powder and a mineral powder, or a mixture of a liquid plant extract and a mineral powder . The mixing ratio of the mineral powder and the plant extract used for preparing the controlling particles may be 5:95 to 50:50 by weight of the plant extract: mineral. The minerals and plant extracts used for preparing the control particles are 50 to 95% by weight, preferably 80 to 95% by weight, based on 100% by weight of the solid content of the total granular composition, 50% by weight, preferably 5 to 10% by weight.

Minerals applicable to the composition of the present invention include zeolite, bentonite, barley stone, mica (pyrophyllite, talc, pyrophyllite, muscovite, pennyite, sericite, Etc.), and phyllite (Phyllite).

Conventional chemical pesticides may contain zeolite as an extender, but in the present invention, even if the plant extract is liquid or powder, the hygroscopicity is very high. Therefore, when the plant extract alone is treated with the seed, physical properties such as collapsibility are reduced, . Therefore, in the composition for controlling agent of the present invention, it is preferable to mix the mineral powder such as zeolite with the plant extract to form the mixture, and to maintain the disintegrating property and the effectiveness persistence after treating the soil controlling agent. Minerals, such as zeolites, also have the function of helping to control the harmful animals in the soil and have a soil-modifying effect in soil treatment. Therefore, according to the present invention, plant extracts, which are active ingredients, and detergent formulations containing minerals have soil remodeling functions as well as controlling functions of harmful animals in the soil.

In zeolites, tetrahedrons of (Si, Al) O4, like feldspar, make a three-dimensional skeletal structure by apical oxygen, but they have voids and include water molecules and exchangeable cations. The water molecules are easily removed by heating at a relatively low temperature, but since the framework of the structure is not changed, the water molecules are absorbed in the air to fill the water. Such water is called zeolitic water. The chemical composition can be expressed as [Wy (Si, Al) (O2xnH2O)]. W is mainly Na and Ca, and includes K, Mg, Ba, and Li.

The controlling composition of the present invention may further comprise a carrier, diluent or excipient suitable for the formulation and / or purpose of use in addition to the above-mentioned effective ingredient.

The composition of the present invention may further comprise a carrier of a natural or synthetic, organic or inorganic substance which, in combination with the active substance, facilitates application of the plant, seed or soil.

The excipient may be a conventional material according to the formulation, and when formulated, a filler, an extender, a wetting agent, a disintegrant, a surfactant, or the like may be used. The diluent or excipient typically used may include water, dextrin, calcium carbonate, lactose, propylene glycol, liquid paraffin, physiological saline and the like, preferably 0.01 to 10% per liter (L) Secondary distilled water to which 0.1 to 1% of Tween 80 is added can be used.

The present invention relates to a method for producing a granular composition for controlling harmful animals in a soil, comprising the steps of: (1) preparing a powder mixture containing an active ingredient and a mineral substance of saponin or a plant extract containing the same, (2) Spraying the seed particles to mold the control particles, and (3) drying the molded control particles. When the plant extract in step (2) is mixed with the mineral powder as a powder and the powder mixture is put in step (2), the binder is molded while spraying a binder, for example, water or alcohol, It may not. The liquid plant extract may be one obtained by extracting or fractionating a plant, or by mixing a powdery plant extract with water.

Optionally, heat treating the dried control particles at a temperature ranging from 200 to 500 ° C. In the case where the heat treatment is not carried out, it is more preferable in terms of long-term sustainability when used in fresh water conditions.

Optionally, heat treating the dried control particles at a temperature ranging from 200 to 500 ° C. In the case where the heat treatment is not carried out, it is more preferable in terms of long-term sustainability when used in fresh water conditions.

Hereinafter, the preparation of the powder mixture containing (1) saponin or a plant extract containing the active ingredient and the mineral is described in more detail. Specifically, the granules of the active ingredient and the additives are uniformly dispersed and mixed through the steps of pulverizing and mixing the plant extract (camellia or yucca or quillaia).

In the preparation of the mixed raw materials, as the natural substance of the soil harmful animal control agent, one selected from the group consisting of purified high purity camellia oleicera extract, yucca extract, and quillaia extract is used singly or in combination of two or more The concentration of the plant extract is preferably 5 to 50% by weight based on the total weight of the plant extract. When the content of the plant extract is less than 5% by weight, it is difficult to exhibit the expected effect, while when it exceeds 50% by weight, the physical properties are deteriorated.

The sub-raw material minerals are selected from zeolite, bentonite, elvan, sericite and phyllite, which are selected so as to contain zeolite or bentonite, either singly or in combination. At this time, the concentration of the total minerals is preferably 50 to 95% by weight based on the total weight. In this case, the particle size of the mixed raw material is preferably 50 to 500 mesh.

(2) Molding the control particles while spraying the binder onto the mixture and the mineral seed particles will be described in more detail.

A matrix of a product to be molded is formed through a seed preparation step as a basis for going from a powder raw material to a spherical structure, and then a mixed raw material is introduced into the produced seed, and then, in a step of controlling rotation of the molding machine and determining particles, Level ball type granular shape.

The seed production is performed by injecting zeolite or bentonite beads (for example, 0.1 to 0.2 mm in diameter), which is an auxiliary raw material, into a ball molding machine drum, and spraying water while rotating to form a base of a spherical structure. The seed production period may be 3 to 6 days, considering the production efficiency, but is not limited thereto. If the natural drying is excessive during the production of the seed, the physical properties may be deteriorated due to the separation of the seed and the plant extract and the mineral compound, which may adversely affect the sustained action of the active ingredient.

In the forming step, particles of a ball type granule are determined through rotation of a molding machine and control of water injection while a mixed raw material is put into a seed. In this case, rotation of the molding machine can be adjusted in consideration of collapsibility between 10 and 100 rpm have. Further, the amount of water to be sprayed is preferably 10 to 50% by weight based on 100% by weight of the whole granular composition. At this time, a proper amount of water should be supplied so as not to be insufficient or excessive to make spherical balls. The particle size of the ball to be formed is preferably 1 to 5 mm, and the particle size can be determined according to the application method. On the other hand, the ball forming period at this time can be set to about 4 to 8 days.

In an embodiment of the present invention, when the plant extract is used as a liquid phase, the water content included in the plant extract may be included in the above range, and the amount of water sprayed in consideration of the water content or the total water content may be determined .

The step (3) of drying the molded particles may include removing the moisture by natural drying, cold air drying or hot air drying, wherein the final moisture content is about 3 to 5% by weight based on 100% . For example, the drying may be carried out at a temperature of 20 to 50 캜 using natural drying or a fan.

Alternatively, the process for preparing the granular composition according to the present invention may further comprise (3) after the drying step, and (4) heat treatment step. The molded product is made to have physical strength and special properties, and the temperature is preferably 200 to 500 占 shortly at a relatively low temperature. More preferably, it is determined in advance whether or not the finished ball-type composition will be carried out because the time at which the finished ball-type composition collapses depends on the environment in which it is treated. It is most effective to omit the heat treatment step in the ball type molding of the present invention. That is, conventionally, the ball type for the pest control agent is fired in order to give the hardness of the ball. However, The calcination is not performed at the temperature condition, and the heat treatment can be optionally performed at a relatively low temperature of 200 to 500 ° C.

And the bio-assay and the physical property confirmation step of the step 6) are completed. In this case, the soil pest control effect can be classified into three types: soil insecticides such as grasses, insect bugs, flea beetles, flea beetles, highland flies, small root flies, earthworms, snails, leeches, And other harmful animals. Also, the physical properties of the finished product are confirmed by confirming the collapsing property, soil permeability and sustainable effect.

The method of the present invention may further include a step of confirming the biological and physical properties of the composition for controlling according to the present invention and the controlling effect of the harmful animals in the soil and the degradability, In this case, the soil pest control effect can be classified into three types: soil insecticides such as grasses, insect bugs, flea beetles, flea beetles, highland flies, small root flies, earthworms, snails, leeches, And other harmful animals. Also, the physical properties of the finished product include degradability, soil permeability and sustainability.

The present invention also provides a method for controlling harmful organisms in a soil, characterized by using the composition or the controlling agent for the soil.

The ball type granular conditioner according to the present invention is not particularly limited in its use, and can be used, for example, for agricultural, livestock, aquatic, architectural, and environmental materials. The content of the plant extract is preferably 5 to 50% by weight based on 100% by weight of the total amount of the control particles. When the content of the plant extract is less than 5% by weight, , And when it exceeds 50% by weight, the physical properties are deteriorated.

The ball type can be processed in various ways. The main method is to treat the formed ball directly on the soil surface or to mix it with the soil. In this case, the artificial or natural water supply gradually dissolves and dissolves, and the effect is constantly maintained. Another method is convenient because it is possible to inject the molded ball into a container with a spray gun and melt it in water and spray it immediately.

The composition of the ball type granular antifungal agent according to the present invention effectively inhibited harmful animals in the soil by containing a plant extract (camellia, yucca or quillaja) and a mineral complex as an active ingredient, and showed an increase in crop growth.
