Description

Eco-friendly herbicide composition having sterilization and insecticidal effect and weed removal method using same}

The present invention relates to a herbicide composition, and more particularly, to an eco-friendly herbicide composition having bactericidal and insecticidal effects and a method for removing weeds using the same.

Organic synthetic herbicides, which are mainly used to control weeds in arable land in modern agriculture, have been mainly used for weed control because of their excellent herbicidal effect and relatively low cost. has caused Moreover, in recent years, serious problems such as the emergence of resistant weeds for most of the developed herbicides have been caused, and the development of new herbicides is required.

In particular, the “Codex Guidelines on the Production, Processing, Labeling, and Distribution of Organic Food” of the International Food Standards Commission established the basic rules for organic farming, which prohibit the use of organic synthetic herbicides in weed control. Only materials derived from organic matter or minerals such as plants and microorganisms are permitted. In addition, due to the worldwide interest in eco-friendly agriculture and the regulations of each country to reduce the input of chemical pesticides into the environment, interest and research on the development of herbicides derived from natural substances are being conducted. Herbicidal active substances derived from natural products are highly likely to express unique chemical structures and functional properties different from those of organic synthetic compounds.

BACKGROUND ART Conventionally, in the cultivation of crops in agricultural land, control of weeds that hinder the growth and harvest of crops has been demanded. In addition, effective control of weeds even in non-agricultural land is beneficial to the use of the land. As described above, control of weeds is required in both agricultural and non-agricultural land, and various herbicides have been used until now. In addition, the application of eco-friendly farming methods is increasing due to the increase in the demand for eco-friendly agricultural products to prevent pesticide poisoning and environmental destruction, so an efficient method for removing weeds without the use of chemical herbicides is required.

Such eco-friendly weeding work requires manual work in reality, and as a large cultivated area increases, a correspondingly large amount of labor is required. However, it is still difficult to implement an eco-friendly organic farming method that does not use chemical herbicides due to the lack of labor force in rural areas and the aging of the agricultural population.

On the other hand, in Prior Art Document 1 (Republic of Korea Patent Publication No. 10-1814000, name: Eco-friendly weed remover), an eco-friendly weed remover composed of brine, vinegar, nitrogenous fertilizer, soju, makgeolli and an electrodeposition agent is disclosed, and prior art Document 2 (Republic of Korea Patent Publication No. 10-1877242, title: Composition for improving the turf growth environment containing natural salt as a main raw material and a method for controlling weeds using the composition), weeds composed of brine, vinegar, oryzaline and an electrodeposition agent Control agents are disclosed. However, in the case of Prior Art Documents 1 and 2, there was a problem in that the weeding efficiency was lowered compared to the conventional organic synthetic herbicides.

Accordingly, there is a need to develop an eco-friendly herbicide that uses natural-derived raw materials but has the same weeding efficiency as that of a chemically synthesized herbicide.

Eco-friendly herbicide composition according to an embodiment of the present invention based on 100 parts by weight of water; 1 to 25 parts by weight of wood vinegar; 0.01 to 10 parts by weight of peracetic acid; 0.01 to 10 parts by weight of sodium alginate; 0.01 to 10 parts by weight of silicate; 0.01 to 10 parts by weight of chlorella extract; 0.01 to 10 parts by weight of cineol; 0.01 to 10 parts by weight of calendula; and 0.01 to 5 parts by weight of coral extract minerals.

Hereinafter, the components of the present invention will be described in detail.

As a component of the herbicidal composition of the present invention, water may use distilled or demineralized water without salinity, and in addition, deep sea water, glacial water, Jiangsu water, hexagonal water, electrolytic reduced water, silver ionized water, and a kind of functional water selected from the group consisting of gold ionized water. Single water, or mixed water consisting of a mixture of two or more types of functional water can be used.

The functional water is rich in minerals to fertilize the soil and preserve harmless microorganisms present in the soil.

Specifically, the deep sea water is seawater with a depth of 200 m or less where sunlight does not reach, and the minerals are dissolved in a stable state because there is little change at a low temperature throughout the year, so it is rich in nutrients. In addition, the deep sea water contains only a very small amount of micro-organisms, hardly any disease-causing bacteria, and is rich in various nutrients including nitrogen and phosphoric acid of 60 species. In particular, it contains minerals such as calcium or magnesium, _{and contains a lot of silicate (SiO 3} ), so it can be usefully used in a herbicide composition.

The glacial water is water filtered through a natural filtration device such as granite, gravel, and fine particles as pure ice that is not affected by contaminants formed from ice thousands of years ago before industrialization melts and becomes water. It can be useful.

The Jijang water is water from which loess has been filtered, far-infrared rays are emitted, various minerals are contained, and can serve to neutralize toxic substances to restore the soil's stamina.

The hexagonal water has a hexagonal structure in which the water molecular structure is subdivided and ion-activated by strong magnetic field energy.

The electrolytic reduced water is quickly absorbed by plants because the size of the water (cluster) is small, thereby increasing the absorption rate of the herbicidal component to increase the weeding effect, and bacteria cannot live. It can also act as an antioxidant by removing free radicals due to its high reducing power (ORP). It can also perform the function of neutralizing the acidity of the soil.

The silver ionized water is obtained by dissolving silver ions in pure, non-mineralized distilled water, and is rich in various minerals, and can perform far-infrared emission, sterilization, antibacterial action, deodorizing action, and the like.

The gold ion water is obtained by dissolving gold ions in pure, non-mineralized distilled water, and is rich in various minerals and can detoxify particularly toxic substances.

As a component of the herbicide composition of the present invention, 80 to 90% of wood vinegar is water and the remaining 10 to 20% is composed of organic compounds, and generally has a pH of 2 to 3 with acetic acid as the main component (about 3 to 7%). It is an acidic aqueous solution of formic acid, formaldehyde, phenolic acid and other wood pyrolysis substances such as tar components. The specific gravity is about 1.010 to 1.030, and it is very effective as a soil disinfectant. It becomes a nutrient source for microorganisms such as actinomycetes and helps the effective growth of microorganisms. The wood vinegar is used to improve the sterilization effect and the effective microbial growth effect.

The wood vinegar can be used in a reddish-brown transparent liquid state by aging and refining the crude wood vinegar obtained by extracting smoke by a cooling device in the carbonization process of burning charcoal for at least 6 months.

The wood vinegar used in the composition of the present invention can be obtained by a known method for preparing wood vinegar, but it is preferably prepared according to the following method.

Specifically, a green plant is heated, distilled, or roasted in a cauldron at atmospheric pressure or reduced pressure, and the steam generated in the heating, distillation, or roasting step is collected, cooled and condensed, and contained in the cooled or condensed wood vinegar. Oil-water separation is performed to recover oil. The oil-water separated material is aged for chemical stabilization, and foreign substances contained in the wood vinegar are separated and filtered. Then, the wood vinegar is stirred and evaporated to remove the harmful components inside, and the wood vinegar is prepared by distilling to recover the steam generated from the wood vinegar.

The wood vinegar prepared in this way may be used as a pest control agent, a disinfectant, a disinfectant, a cleaning agent, an environment improving agent, a plant nutrient, a soil improving agent, or a odor remover. By atomizing the prepared wood vinegar composition with ultrasonic waves, physical and chemical properties are changed to maximize the contact effect with pests and plants, soil and odor substances, and improve pest prevention and odor removal.

The green plants according to the present invention are specifically oak, bamboo, juniper, cypress, cypress, cypress, olive, spruce, persimmon, chestnut, apple, pear, peach, vine, citron, and tangerine trees. , cherry tree, ginger tree, jujube tree, plum tree, quince tree, fig tree, apricot tree, pomegranate tree, ginkgo tree, walnut tree, fern tree, birch tree, biji tree, birch tree, zelkova tree, maple tree, camellia Trees, mulberry trees, cherry trees, acacia trees, alder trees, pine trees, fir trees, cypress trees, pine trees, cedar trees, birch trees, hackberry trees, yum trees, aspen trees, mulberry trees, sancho trees, oak trees, cinnamon trees, willow trees, mugunghwa trees, oak trees Tree, Schisandra tree, ash tree, elm tree, ginger tree, alder tree, paulownia tree, birch tree, wisteria, arrowroot tree, thyme tree, cornus tree, green tea tree, forsythia, azalea, dandelion, horseradish, eoseongcho, rice straw, barley It is at least one selected from straw, reed, garlic, onion, grass, and mugwort.

The heating process heats the green plant in a temperature range of 80°C to 150°C. Heating below 80°C contains a lot of moisture, and when it exceeds 150°C, the tar component increases, the content of harmful components such as phenols, aldehydes, and alcohols increases, and the smell of wood tar is strongly generated. It is preferable to use a wood vinegar obtained by heating in a temperature range of ℃ to 150 ℃.

The process of distillation means heating a liquid to its boiling point and cooling the evaporated material to make it a liquid again. When purifying a liquid, or when the liquid is a mixture, it is mainly used for the purpose of separating it into each component. During distillation, the first thing that evaporates is a substance with a low boiling point, and the substance that comes out later is a substance with a high boiling point. According to the present invention, it is possible to prepare a liquid obtained by heating a green plant containing moisture, etc. by additionally including water and collecting the generated vapor as wood vinegar.

The roasting process refers to heating and cooking plants or medicines containing moisture without adding water. The process of heating a cauldron hot, adding green plants, and roasting it is similar to the method commonly used for producing green tea. After ripening moderately and rubbing by hand, repeat the second rubbing process again. It is possible to prepare wood vinegar by collecting the steam generated during this process.

The steam generated through the heating, distillation, or boiling process is collected at a temperature range of 80°C to 150°C, cooled and condensed. The resulting wood vinegar is aged at 20° C. or higher for 4 to 6 months to stabilize it. Then, it goes through a filtration process that reduces the concentration of soluble tar contained in the wood vinegar prepared by using a direct heating furnace. The pore size is filtered one or more times with a filter having a pore size of 0.2 to 1.0 micrometer, or the dissolved tar component is separated to be 1 mg/L or less by high-speed rotational centrifugal force of 3,000 RPM or more.

Compared with the pyrolysis process, the process according to the present invention produces less tar and has the effect of reducing cost and time because the process of filtration and separation is simple. In order to further lower the concentration of methanol, formaldehyde, acetaldehyde, phenol, etc. contained in the wood vinegar, stirring and evaporation are performed. By evaporating the irritant gas while stirring the internal temperature of the wood vinegar at 40°C to 90°C for at least 1 hour at about 50 RPM to 100 RPM, a wood vinegar composition with excellent deodorization performance can be obtained. Distillation increases the organic acid concentration of the wood vinegar composition to obtain a distillate by heating the internal temperature at 95° C. to 105° C. to produce a high-quality product.

It may further include a step of heating in order to shorten the aging period in the aging step. In addition, it may further include the step of removing the harmful components inside the wood vinegar by direct or indirect heating in the evaporation step. In addition, at least one selected from the wood vinegar of the cooling and condensation step, wood vinegar of the oil-water separation step, wood vinegar of the aging step, wood vinegar of the filtration step, wood vinegar of the stirring step, wood vinegar of the evaporation step, and wood vinegar of the distillation step can be mixed and used. In addition, in the wood vinegar, the smoke generated by direct or indirect thermal decomposition of green plants such as conifers and broadleaf trees at 150 ° C to 450 ° C. And it can be prepared by mixing at least one selected from the wood vinegar that has undergone the evaporation step, and the wood vinegar that has undergone the distillation step.

Since the wood vinegar prepared by the above method acts to decompose the decomposition rate of water molecules three times faster, when the herbicide containing wood vinegar prepared in the present invention is diluted with water and used, the effect of weeding is increased and the effect is increased. In order to maximize, it is preferable to include 1 to 25 parts by weight of wood vinegar based on 100 parts by weight of the water. If the content of the wood vinegar is less than 1 part by weight, the sterilization effect may be reduced, and if the content of the wood vinegar exceeds 25 parts by weight, the sterilization effect is excellent, but the growth of microorganisms may be reduced.

In addition, the wood vinegar may further include a mixture of ginger juice and fruit extract in order to maximize the sterilization effect and the herbicidal effect. The fruit extract is obtained by ripening one or more fruits selected from the group consisting of apples, bananas, kiwis, pears, pomegranates and grapes, pulverizing and freeze-drying them, put them in butylene glycol containing water as a solvent, ultrasonic extraction and supercritical fluid As a fruit extract filtered through a nanofilter after extraction, the fruit extract prepared by this method is manufactured in nano size and synergistically with the active ingredient of ginger juice, thereby remarkably improving the sterilization and weeding effect of wood vinegar.

Next, step d) is a filtration, separation and concentration step, wherein the filtration is first filtered with an ultra-filter, and then filtered again with a nano-filter to obtain a nano-sized extract, which is The fruit extract according to the present invention can be obtained by concentration for 5 hours. When the concentration exceeds the above temperature, the active material may be deformed, and if the concentration time is exceeded, the efficiency of the operation may be reduced.

The extraction of the fruit extract according to the present invention is a low-temperature extraction, and it is possible to suppress the inactivation of active substances by temperature, to reduce the production cost for maintaining a high temperature, and to obtain a high yield, thereby improving the efficiency of material use. It also has an elevating effect.
