Description

Functional composition capable of both soil pest control and soil improvement}

The present invention relates to a functional composition capable of controlling soil pests and improving soil at the same time, and more specifically, as a drug efficacy enhancer, plant extracts extracted from Neem, Yangmyeongju, P. china, and Camellia sinensis, neem oil (Azadirachtin), or neem-cake. , cinnamon oil (cinnam-aldehyde), dolomite, animal by-products, sulfur, etc., and starch, glucose, diatomite, etc. as binders or excipients are reviewed and formulated to control soil pests. It relates to a functional composition that can simultaneously improve and improve soil.

Plant parasitic nematodes, which are widely distributed around the world and cause damage to crops, damage the above-ground parts of plants or damage the roots of plants while living in the soil. Among various plant parasitic nematodes, root-knot nematodes are the most difficult to control and cause the greatest damage.

Control methods for these root-knot nematodes include cultural control, physical control, and chemical control.

Agronomic control includes freshwater, fallow, dry soil, deep plowing, fertilized soil, rice rotation, and resistant varieties. Physical control includes heat treatment (steam, dry heat, hot water immersion) and solar disinfection. Chemical control includes Poscia. Root-knot nematodes are controlled by spraying chemical agents such as jate (nematode charcoal).

To control this, soil disinfectants are used to suppress the decrease in crop yield due to the increase in the density of parasitic nematodes, and a wide range of nematicides such as organophosphorus fosthiazate, cadusafos, and batsamide (active ingredient: dazomet) are used. It is being used extensively. Although these chemical synthetic pesticides have recently shown a clear tendency to be converted to low-toxicity pesticides, they exhibit at least grade 4 toxicity to the human body, and are substances that remain in the soil and flow into rivers with rainwater, showing grade 3 or higher toxicity to fish. In most cases, their use has had problems threatening the dietary safety of recent consumers.

Physical control is a method of controlling pests using physical means rather than chemical or biological control when exterminating weeds or pests, and includes seedling disinfection and soil disinfection.

Seedling disinfection is carried out to prevent the occurrence of infectious diseases in seedlings. There are hot water acupuncture methods, cold water acupuncture methods, bath acupuncture methods, and solar heat use methods. Soil disinfection is performed to prevent the occurrence of soil infectious diseases. The topsoil of the field is scraped up and burned with a combustible agent, or the soil is placed on an iron plate and heated from below to disinfect it, and high-pressure steam from a boiler is sprayed into the ground through a pipe to poison it. To disinfect a relatively small amount of soil, such as steam sterilization and clay, it is an electric sterilization method in which soil is placed in a container containing an electric heating device and heated to sterilize it.

Injection poisoning requires special facilities or machines and is carried out in an electric disinfection experiment, so soil disinfection is not carried out due to the improvement of soil disinfectants.

Pesticide control is a method of controlling harmful organisms such as pests and weeds using chemicals (medicines). It is effective and fast, but there is a risk of causing damage and the problem of killing natural enemies at the same time.

The technology behind the present invention is Patent Publication No. 2007-0035646, “Agricultural nematode control composition containing cinnamon aldehyde isolated and purified from cinnamon” (Patent Document 1). The above background technology proposes 'an agricultural nematode control agent containing the filtrate obtained by pulverizing cinnamon (Cinnamomum cassia), adding 70% hydrous alcohol (5 times its weight), extracting it at 4-40°C for 12 hours, and then filtering it.' However, the above background technology has not yet disclosed a use having a nematicidal effect on root-knot nematodes with the same configuration as the present invention.

The present invention relates to a functional composition capable of controlling soil pests and improving soil at the same time, and more specifically, as a drug efficacy enhancer, neem oil (Azadirachtin) or neem-cake, and vegetable extracts extracted from Neem, Yangmyeongju, Prickly pear, and Tea tree. , cinnamon oil (cinnam-aldehyde), dolomite, animal by-products, sulfur, etc., and starch, glucose, diatomite, etc. as binders or excipients are reviewed and formulated as a soil pest control agent. It relates to a functional composition that can simultaneously improve and improve soil.

The present invention uses a liquid agent mixed with fermented fish by-products, vegetable extracts, neem oil, and cinnamon oil in a powder made of diatomaceous earth, dolomite, neem cake, sulfur powder, seaweed extract, corn starch, and jicama meal. .

Diatomaceous earth refers to rocks or sediments formed by the remains of diatoms, single-celled organisms, after they die. Most diatomaceous earth is white and may have particles of about 3㎛ or less or more than 1mm, but usually consists of fine-grained particles of about 10-200㎛. The general chemical composition of dried diatomaceous earth is about 80-90% silica, about 2-4% alumina, and about 0.5-2% iron oxide.

In agriculture, diatomaceous earth is used not only as an insecticide but also as an anti-caking agent. Some farmers use diatomaceous earth to keep their livestock's food from hardening and to serve as a growth medium in hydroponic cultivation. In growing vegetables, diatomaceous earth, like expanded clays such as perlite and vermiculite, is used as a soil conditioner because it increases oxygen circulation while preserving water and nutrients even during drainage. It is used.

Dolomite or dolomite is named after the French geologist Dolomew, who first described this mineral. Dolomite means 'white cloud-like mineral' and is also called a paleofossil. It is a mineral belonging to the trigonal system and its fossil component is CaMg(CO ₃ ) ₂ . Calcium carbonate (CaCO ₃ ) and magnesium carbonate (MgCO 3 ) form a complex carbonate in a 1:1 ratio, and are colored white, gray, pink, yellow, brown, or green. They are transparent or translucent and have a glassy luster, and the crystals sometimes have a pearlescent luster.

For use in the agricultural field, dolomite is crushed to a particle size of 28 to 10 mesh and used as fertilizer, which is called lime kaolin fertilizer. Like quick lime and slaked lime fertilizers, it is a soil conditioner for acidic soils and neutralizes the soil. It also supplements nutrients such as chlorophyll (Mg), inhibits heavy metal absorption, promotes microbial activity, prevents diseases and pests, increases crop production and improves quality, and protects farmland. There is.

Sulfur is one of the natural substances used by mankind to control diseases and pests arising from crops. According to an old European book, Homer, around the 9th century BC, described sulfur as a substance that pests avoid. Sulfur as a fungicide began to be used in earnest in France in the 1800s to control powdery mildew on grapes, as wine production decreased to 80 parts by weight due to powdery mildew on grapes. It was introduced to the United States in 1845, and was effective in controlling not only powdery mildew on grapes but also mites in grape orchards. It came to be used widely.

Pure sulfur is a crystalline yellow solid that is very stable and insoluble in water. It has been reported that when administered directly to the human body, it is highly toxic and may cause side effects. Despite its toxicity, sulfur is an organic material and is allowed to be used in the United States, Europe, and Korea. And currently, in Korea, it is permitted as a raw material for eco-friendly organic materials that can be used for eco-friendly organic pest control purposes, and products containing sulfur are sold.

In Korea, studies have reported that applying powdered sulfur directly to the soil improves the quality of fruits and vegetables and garlic or has a disease control effect.

Jicama ( Pachyrhizus erosus , Yam bean) is a vine of the legume family and is called ‘Mexican potato,’ ‘Mexican turnip,’ or ‘bean potato.’ It is native to Mexico. The surface is yellow and the peel peels off easily. The inside is cream-colored, similar to a pear or potato. It has a sweet taste and a crunchy texture. There is an expression that the taste is like ‘a savory apple.’ Except for the roots, stems, leaves, and seeds are used as pesticides. The leaves and stems are toxic, so it is resistant to pests and diseases and grows well anywhere.

Jicama contains an insecticidal ingredient called rotenone. Rotenone is a colorless crystal with the chemical formula C23 H22 O6. The melting point is 163℃. It is almost insoluble in water, but dissolves in acetone, chloroform, etc. As a vegetable pesticide, it is particularly effective against cucumber fern flies. It has low toxicity to humans and livestock. When the jicama leaves and seeds used in the product were supercritically extracted at 50°C and 400 bar for 15 minutes, the rotenone content was about 1%.

Jicama leaf extract has an insecticidal effect on Chrysomya bezziana fly larvae and maggots, and the seed extract or insecticidal components of the seed extract have an insecticidal effect on white-stalked mosquito larvae, cotton aphids, white-tailed moths, and cabbage moths, so they can be widely used in the agricultural field. .

To increase yield, jicama ( Pachyrhizus erosus , Yam bean) cake can be formed by crushing jicama seeds, adding 20 times the amount of hexane as jicama seeds, and then extracting at room temperature for 24 hours.

Seaweed extract is made from various seaweeds and is a natural product that does not add any chemical processes or compounds to the product during or after manufacturing.

Such seaweed extract is a natural growth promoter of plants and can be used as a natural organic material, and is composed of powerful raw materials of primary and secondary nutrients and various bioactive agents. In the present invention, a product made by powdering seaweed extract is used. do.

In the present invention, neem cake is used as a powder.

Neem is a member of the neem family (Meliaceae) and its scientific name is Azadirachta indica .

It is a semi-evergreen tree that grows widely in subtropical and tropical regions, and more than 50 parts by weight of it is found in India. White flowers bloom in February and March, and the green fruits that grow after the flowers ripen turn yellow in July and August, making them a favorite among birds. It is resistant to drying and has high salt resistance. The fruit is edible and is also used as a folk medicine.

Neem tree bark is cold, bitter, and astringent, removes poison, and purifies the blood. Neem oil extracted from the fruit has a unique scent and is not used for food.

The fruit has a bitter taste and is used as a hemorrhoid medicine and anthelmintic. The seeds are also bitter in taste, used as an insect repellent, and have a detoxifying effect. 45 parts by weight of oil is extracted from the seeds. It is a bitter oil with an odor similar to garlic and sulfur, and is rich in fatty acids and contains vitamin E and essential amino acids.

Azadirachtin, the main ingredient in neem cake, affects the growth and reproduction of insects and is useful as a biological pesticide.

In particular, if the raw materials contain a lot of minerals (dolomite, diatomaceous earth, etc.), they cannot be formulated or easily break down, so corn starch, a natural ingredient, was used as an excipient to enable formulation.

In the present invention, the liquid agent is formed by mixing fish by-product fermentation liquid, plant extract, neem oil, and cinnamon oil.

Fish by-products are by-products of the seafood processing industry and are a collection of parts that are unsuitable for human consumption. The nutrient content varies depending on the fish species, but the content of high-quality protein is high at around 35-75% and amino acids such as lysine, methionine, tryptophan, and threonine. It is rich in vitamin B group.

In the present invention, a variety of naturally derived plant extracts such as neem, columbine, prickly pear tree, clove, and tea tree can be used as the vegetable extract. In particular, tea tree extract can be used as the plant extract.

Tea tree is an evergreen broad-leaved shrub. Its scientific name is Camellia sinensis . Camellia refers to the genus Camellia. Camellia sinensis var., which is mainly used as green tea in Korea. sinensis is cultivated in Jeolla-do, Gyeongsang-do, and Jeju-do. Camellia sinensis var. mainly used for black tea. assamica is cultivated in places such as India and Sri Lanka.

It is a subtropical evergreen shrub that can grow into a small tree depending on the environment. For convenience of harvesting, trim them to a height of about 1 meter. The branches diverge a lot. First-year branches are white and have fine hairs, and second-year branches are grey-brown and hairless. The leaves are usually alternate, lanceolate, and oval in shape, with green veins on the surface and grey-green veins on the back, with no hairs on both sides. Flowers bloom in October-November, are 3-5cm in diameter, are white, fragrant, and 1-3 are axillary or hang at the ends of branches. The fruit ripens in the fall of the following year, and the seeds are round and hard.

The seeds of the tea tree are also used for cosmetics and edible purposes, and the oil squeezed from the seeds is also used as fertilizer or livestock feed and as a substitute for soap.

The tea tree extract is concentrated and extracted by repeating the process of washing the tea tree seeds, pulverizing them with a grinder, mixing solvents, extracting, mixing with 95% by weight alcohol and concentrating under reduced pressure.

After pulverizing 100g of tea tree seeds with a grinder, add 20 times the amount of solvent as the pulverized sample into the flask containing the pulverized sample. Afterwards, each sample is placed in a shaker set at an extraction temperature of 50°C and extracted over night. The extraction process is completed and each sample is filtered using gauze and filter paper.

Neem (Melia azedarach) is a deciduous tree belonging to the neem family (Meliaceae). The bark is finely divided and leaves hang at the ends of branches. It is a plant distributed in tropical and subtropical regions. Its bark and root bark mainly contain ingredients such as four-cyclic triterpenoids and flavone anthraquinones, and its bark, fruits, seeds, and leaves have anti-parasitic, antibacterial, and antiviral effects. It is known to have a round oval shape and has a unique odor from its seedlings.

Sophora japonica is a deciduous broad-leaved tree belonging to the legume family. Its branches are green and emit an odor when cut. The leaves are pinnately compound with leaflets. The flowers bloom in August and are yellow-white, cone-shaped flowers. The fruits are narrow pods, about 5 to 8 cm long, and ripen in October. It likes deep, fertile soil, but thrives even when it is not wet and is resistant to pests and diseases.

Chenopodium ambrosioides is an annual plant in the Chenopodium family. The stem has many branches, has sparse hairs on the upper part, and flowers bloom between June and October. The leaves are long, oval-lanceolate, alternate, have teeth of different sizes on the edges, and the petioles are short and have light yellow lines on the back. The fruit is a porpoise, and the seeds are dark brown, round, ovate, and the seedlings of Yangmyeong-Aju have a unique smell.

It was confirmed that when the neem tree, prickly pear tree, and columbine extract were used in a mixture, a superior insecticidal effect was achieved compared to when each extract was used alone.

Wash, dry and grind the leaves, stems and/or roots of Neem and Prickly pear tree pigweed in equal amounts, mix with organic solvent in a weight ratio of 1:10 to 1:40, extract and filter at room temperature for more than 48 hours. Afterwards, the filtrate is completely concentrated using a vacuum concentrator and dried in a freeze dryer to obtain a crude extract.

The organic solvent for preparing the extract of the Neem plant or Pigweed plant can be methanol, ethanol, dichloromethane, hexane or a mixture thereof, preferably methanol or ethanol.

Vegetable oils such as neem oil and cinnamon oil are added to the by-product fermentation liquid and plant extract according to the input ratio and stirred sufficiently for about 24 hours. The sufficiently stirred liquid mixture is added to the above-mentioned powder and stirred, and then Form it into a certain shape using a molding machine and dry it.

In the present invention, it is preferable to mix 25 to 35 parts by weight of liquid agent based on 100 parts by weight of powder. When mixed with less than 25 parts by weight of liquid agent, the formulation does not form and crumbles easily, and when mixed with more than 35 parts by weight, the liquid agent is mixed. Since drying is slow, the hardness of the formulation is low, and economic feasibility is low, it is preferable to mix 25 to 35 parts by weight of the liquid agent.

The powder contains 29 to 43 parts by weight of dolomite, 23 to 27 parts by weight of diatomaceous earth, 12 to 16 parts by weight of neem cake, 1.5 to 2.5 parts by weight of seaweed extract, 9 to 11 parts by weight of sulfur powder, 9 to 11 parts by weight of corn starch, and jicama. It is preferable to mix 2.5 to 3.5 parts by weight of foil.

Diatomaceous earth and dolomite are difficult to formulate if more than 43 parts by weight of dolomite and 27 parts by weight of diatomaceous earth are added, and economic feasibility is poor if less than 29 parts by weight of dolomite and 23 parts by weight of diatomaceous earth are added.

12 to 16 parts by weight of neem cake, 9 to 11 parts by weight of sulfur powder, and 2.8 to 3.5 parts by weight of jicama bag are mixed to enhance the insecticidal effect. If the amount is less than a certain amount, the insecticidal effect decreases, and if added in large amounts, it becomes less economical.

9 to 11 parts by weight of corn starch is an excipient. If a small amount is added, it breaks easily, and if a large amount is added, it does not decompose easily.
