Description

Highly Concentrated Lime Bordeaux Liquid and Manufacturing Method Thereof

The present invention does not cause problems such as clogging of the nozzle when using the lime Bordeaux liquid as a raw material of the lime component, no precipitation of the raw material components during long-term storage, there is no need to stir every use, uniform concentration It has excellent dispersion stability, excellent electrodeposition stability immediately after spraying and after drying, and it does not leave traces of lime material, which causes deterioration of merchandise right after spraying. The present invention relates to a method for producing a highly functional high-purity lime Bordeaux liquid, which provides a reduction in cost and transportation cost.

After discovering that a mixture of copper sulphate and lime are effective against grape germ disease, Bordeaux liquid has been widely used as a disinfectant for many crops such as grapes and fruits and vegetables. Although it is called 'Bordeaux liquid', it is correct to express board as Bordeaux mixture because it is manufactured by using copper sulfate and quicklime as raw materials, so lime does not dissolve and precipitates.

If the conventional method of preparing Bordeaux liquid according to the reaction step can be expressed by the following reaction formula.

CaO + H ₂ O-> Ca (OH) ₂ ... ①

_{CuSO 4 + 2H 2 O → H} 2 SO 4 + Cu 2+ + 2 (OH) - ... ②

Ca (OH) ₂ + H ₂ SO ₄ + Cu ^{2 +} → CaSO ₄ ↓ + 2H ₂ O + Cu ^{2 +} ... ③

As shown in the reaction scheme, quick lime (CaO) is added to water and left for a long time to obtain a lime suspension in which strong alkaline calcium hydroxide (Ca (OH) ₂ ) of pH 11-12 is dissolved by hydration. When copper sulfate (CuSO ₄ ) solution is added to the lime suspension and reacted, sulfuric acid (H ₂ SO ₄ ) is first generated and copper ions (Cu ²⁺ ) which are bactericidal are liberated, gradually precipitated as the reaction proceeds. The calcium hydroxide reacts with the sulfuric acid again to produce water-insoluble calcium sulfate (CaSO ₄ ) and water, and the free copper divalent ions that do not react are present in the water, which acts on negatively charged microbial cells. By doing so, the pathogenic microorganisms are disinfected and play a role in chemical plant control.

However, in the conventional 'Bordeaux liquid', only lime can be used as a starting material when preparing a lime solution, so that lime is hardly dissolved when reacted with water, so that a large amount of lime powder remains in the Bordeaux solution, and an active ingredient of the Bordeaux liquid composition Phosphorus 'basic copper sulfate / calcium sulfate' also has a high specific gravity, so these components are separated and settled due to the specific gravity difference. Therefore, in order to maintain the dispersion stability of the prepared Bordeaux liquid, there are various problems in use, such as to be dispersed as soon as possible after preparation.

In any case, dispersion stability gradually decreases immediately after preparation of Bordeaux solution. For example, when the Bordeaux solution prepared for the next day is used for the next morning, an insoluble component is added to the bottom of the container. Problems that frequently occur due to sedimentation and impossibility of spreading work occur frequently. In addition, even if you try to force the stirred 'Bordeaux liquid' to be used for the spreading operation, it may cause caking and redistribution, or even if it can redistribute, clogging the nozzle of the chemical spreader, leaves, fruits, etc. There is also the problem of remaining attached to the surface of the workpiece.

Due to the low dispersion stability of Bordeaux liquid, it is not only hassle to prepare and use immediately, but also the quality as 'Bordeaux liquid' is not constant according to the worker's experience or the quality of copper sulfate or lime. Even weakening occurs due to the concentration of copper ions or lime. Therefore, most of the prior art regarding improvement of Bordeaux liquid has been to increase these dispersion characteristics.

In addition, when sprayed on fruit plants such as grapes, peaches, and citrus, insoluble calcium hydroxide or insoluble calcium sulfate adheres to the leaves of the fruit plants, inhibiting vigorous respiration and blocking the sun. Decreased photosynthesis rate may adversely affect the ripening of fruit. In addition, when the yellow-white water-soluble calcium compound or insoluble calcium compound adheres to the fruit or red pepper, there is a disadvantage that it impairs the aesthetics of the product.

However, as another problem of the Bordeaux liquid, it is necessary to consider maintaining a stable electrodeposition effect after dispersion. If the electrodeposition stability is poor even with the Bordeaux liquid composition excellent in the dispersion stability, depending on the surface state of the product to be dispersed, a lack of electrodeposition ability, such as splashing of the dispersion liquid, resulting in a uniform application of the chemical liquid. In addition, the lack of electrodeposition ability may cause the drug to be easily peeled off due to physico-chemical factors such as rainwater or wind after spray drying, resulting in the inability to expect stable long-term efficacy.

Low dispersibility due to the use of lime for the production of Bordeaux liquid makes it impossible to use long-term storage of Bordeaux liquid, and makes it impossible to concentrate more, which requires a large amount of packaging containers and increased transportation costs. There is a drawback of not being able to prepare Bordeaux solution, which also requires a solution.

In addition to solving the above problems and disadvantages, Bordeaux liquid is required to be effective in a variety of pathogens and bacteria, a high functional eco-friendly disinfectant by mixing wood vinegar or antibiotics in Bordeaux liquid, but is a natural material disinfectant As a pest control agent, a highly functional 'Bordeaux liquid' that satisfies each required characteristic has not been proposed yet.

Bordeaux liquid is an eco-friendly organic material that has been widely used as a fungicide for many crops, including many fruits and vegetables, after being found to be effective against grape germ disease. However, the conventional Bordeaux liquid is prepared by simply mixing quicklime and copper sulfate, and lime, which is a component, causes a lot of inconveniences and disadvantages such as deterioration of stability when using Bordeaux liquid. In other words, due to the large amount of lime powder precipitated in the prepared Bordeaux liquid and 'basic copper sulfate / calcium sulfate' as an active ingredient of the Bordeaux liquid composition, it can cause stable dispersion for a long time because it causes poor dispersion at both concentration and use concentration before use. After spraying on leaves or fruit trees, they adhere to the surface of leaves and fruits of fruit trees to inhibit vigorous respiration or block sun, resulting in lower photosynthesis rate of plants, and yellowish white precipitates When adhered to, it impairs the aesthetics of the product and lowers its value as a product of agricultural products. In addition, the electrodeposition effect is lowered after spraying, even after drying, it is easily peeled off by physical external pressure or rain water of the external system so that the drug efficacy does not continue. In addition, such a decrease in stability of Bordeaux liquid is impossible to high concentration of liquid, leading to an increase in sales and transportation costs as a product.

In addition, deterioration of chemical stability due to the occurrence of these precipitates to limit the incorporation of drugs or ingredients having an effect on other pests has a problem that it is not easy to manufacture a high quality multifunctional Bordeaux liquid having pest killing and bactericidal properties other than the effects of conventional Bordeaux liquid. .

The present inventors have solved the disadvantages and drawbacks of the conventional Bordeaux liquid, and researched and devised a method for producing a new Bordeaux liquid capable of high concentration of multifunctionality applicable to various diseases and pests.

Hereinafter, the present invention will be described in detail.

The present invention is to prepare a high-concentration 'Bordeaux solution' of high functionality by mixing the complexed lime solution and copper sulfate solution, the complexed lime solution is to use a lime solution completely dissolved in a solvent by complexing the calcium source with a chelating agent It relates to a Bordeaux liquid and a method for producing the same,

Specifically, the highly functional highly concentrated lime bordo solution of the present invention is a complexed lime solution in which a calcium source is complexed with a chelating agent and dissolved in water or another solvent; Copper sulfate solution in which copper sulfate is dissolved in water or another solvent; The complexed lime solution is characterized in that it comprises the copper sulfate solution.

Specifically, the production method of the highly functional high-purity lime Bordeaux liquid of the present invention

(1) complexing the amount of calcium source required for concentration to a desired concentration with a chelating agent to dissolve the calcium source in water or another solvent to form a complexed lime solution free of precipitation;

(2) dissolving the amount of copper sulfate required for concentration to a desired concentration in water or another solvent to prepare a copper sulfate solution;

(3) stirring while adding the copper sulfate solution to the prepared precipitated lime solution;

(4) And phytoncide instead of water as the other solvent for dissolving lime or copper sulfate in step (1) or (2) for the preparation of 'Bordeaux solution' applicable to various pests and bacteria beyond the sterilization effect of the conventional Bordeaux solution Use of solvents containing components;

It provides a method for producing a multi-functional high concentration Bordeaux liquid, characterized in that.

The present invention also provides a lime solution in which a calcium source is dissolved in a solvent containing a phytoncide component; Copper sulfate solution obtained by dissolving copper sulfate in a solvent containing a phytoncide component; It provides a high functionality lime bordeaux solution comprising the lime solution and the copper sulfate solution.

Recently, multifunctional Bordeaux liquid is required to be effective in various pathogens and bacteria. A high functional eco-friendly disinfectant is proposed by mixing wood grass or antibiotics with Bordeaux liquid, but it is basically a natural material disinfectant or pest control agent that satisfies each required characteristic. High functional 'Bordeaux liquid' has not been proposed yet, the present invention provides a lime Bordeaux liquid showing a variety of environmentally friendly functions by using a solvent containing a phytoncide component as a solvent.

In addition, the solvent containing the phytoncide component may be an aqueous phytoncide aqueous solution or an oily organic phytoncide essence, or may be used by mixing an aqueous phytoncide essence with an oily phytoncide essence.

In the case of lime solution complexed in the high-functional high-concentration lime Bordeaux solution and its preparation method;

In the conventional 'Bordeaux liquid' production, calcium component (calcium source) is prepared based on quicklime (CaO), which is insoluble in water or most polar solvents, which is a fundamental cause of most of the disadvantages of the 'Bordeaux liquid'. Therefore, all the disadvantages can be eliminated if the calcium component can be present in the liquid ionic phase rather than in the solid phase. In this study, the solution of the problem is achieved by complexing (chelating) the calcium component using a chelating agent. By using the chelating agent to ionize the calcium component, the Bordeaux solution produced without precipitation in the lime solution not only ensures high uniform stability, but also has a sufficient amount of calcium component than the amount of calcium in the conventional Bordeaux solution. Since it can be uniformly present, it is possible to manufacture a highly concentrated Bordeaux liquid.

In the case of a highly functional high concentration lime Bordeaux solution and a lime solution complexed in the preparation method thereof,

The amount of calcium source and the amount of complexing agent required for concentration to the desired concentration is based on 1000 parts by weight of water or other solvents necessary to make the lime solution.

The calcium source is 2.0 to 50 parts by weight, the complexing agent (chelating agent) is characterized by mixing 3 to 8 times by weight of the calcium source.

2,0 parts by weight of calcium source is the minimum amount of calcium source expressing the efficacy of conventional Bordeaux liquid is less than 2,0 parts by weight, it is difficult to expect the drug efficacy, it is used when applying a calcium source amount of 50 parts by weight or more This is because the calcium source may be precipitated without dissolving in an amount that is excessively dissolved as a chelating agent.

And when the amount of the complexing agent is applied to less than three times the calcium source, the complexing of the calcium component is not made completely, if more than eight times because the excess is no longer required.

More specifically, it is preferable to use quicklime as a calcium source, quicklime is 2.0 to 50 parts by weight, complexing agent (chelating agent) is characterized in that 3 to 8 times by weight of the quicklime. In the case of 2.0 parts by weight of quicklime, the minimum amount of quicklime expressing the efficacy of conventional Bordeaux liquid is less than 2.0 parts by weight, and it is difficult to expect the drug efficacy. When applying an amount of lime of 50 parts by weight or more, it is too much to dissolve as a chelating agent used. This is because the quicklime can be precipitated without dissolving in an amount. And the amount of the complexing agent is applied to less than three times the quicklime, the complexing of the calcium component is not made completely, if more than eight times because the excess is no longer required.

In addition, the lime Bordeaux solution of the present invention may have a small amount of impurity components that are not complexed according to the purity of the lime raw material complexed at the time of manufacture, precipitation may occur at the bottom of the Bordeaux solution, but the supernatant from which these precipitates are removed is still chelated. Highly concentrated lime Bordeaux liquid in the prepared state, the effect is the same even using only the supernatant.

In the step of preparing a highly concentrated lime Bordeaux solution and a complexed lime solution in the production method, the chelating agent (complexing agent) that can be used to dissolve calcium is EDTA, EDTA.2Na, EDTA.4Na, acetic acid, lactic acid, citric acid, Aqueous solutions of organic acids such as succinic acid, malic acid, tartaric acid, butyric acid, palmitic acid, tartaric acid, gluconic acid, sodium gluconate, acetic acid, propionic acid, oxalic acid, sodium oxalate, glycolic acid, amino acids, fermented acid solution, vinegar and fermentation It is characterized by using any one or more selected from the vinegar.

In order to prepare a 'Bordeaux solution' applicable to various pests, the phytoncide aqueous solution is used as a solvent used to dissolve calcium in the step of preparing the complexed lime solution.

Phytoncide is known for its use as a very effective natural pest control agent. However, when the phytoncide is usually extracted and introduced into the Bordeaux liquid solution in an aqueous phase as an oily phase, the liquid stability and uniformity of the Bordeaux liquid are lost, and the phytoncide is not easily mixed. Therefore, in the present invention, when extracting the phytoncide component by steam distillation method on coniferous trees including phytoncide, cedar, cedar, pine, pine, etc., the aqueous phase phytoncide essence of oil phase having high volatility and the water-soluble phytoncide component A phytoncide aqueous solution is obtained, and the phytoncide aqueous solution obtained here is used as a solvent for dissolving calcium sources such as quicklime.

In addition, it is possible to prepare a 'Bordeaux liquid' applicable to various pests by introducing an organic phase phytoncide essence in oil form, but in this case, it is possible to substitute the use of an aqueous phytoncide solution by emulsifying the organic phase phytoncide essence in oil form.

In addition, phytoncide essences are highly volatile and require a release control technique to prevent volatilization during action on pests. Sustained release means to release the trapped material slowly. To do this, the phytoncide essence is enclosed in a microcapsule with fine pores to allow the phytoncide to slowly leak out.

In addition, the solvent containing the phytoncide component may be used by mixing the phytoncide aqueous solution and the phytoncide essence into a microcapsule.

The phytoncide can be used as a natural pest control agent because it contains the following components:

1) Verbenone (Verbenone): Terpene is a kind of pheromone, and has an anti-inflammatory activity. Trees secrete a substance called terpenes. There are about 144 kinds of terpenes that are produced by trees, including the essential oils, resins, and carotene that we know. The efficacy of terpenes is varied. The most well known are those that kill or inhibit the growth of bacteria, fungi, parasites, insects, etc. Terpenes are used as insecticides, fungicides, preservatives, skin irritants, anti-inflammatory agents, disinfectants, and fatigues. It is also used as a replica. Terpene secreted from the tree is volatile, so it is mixed in the air. When absorbed by the human body, it can activate the body, stabilize the mind, sterilize, and kill insects. Terpenes can stimulate the body's biological activity when we take a certain amount.

2) alpha-terpineol: strong antiseptic and antiseptic effect against bacteria, viruses, molds, acne-induced bacteria, athlete's foot fungus and scalp-induced fungal activity prevention, prevention of whitehead and blackhead formation through sebum removal It has been reported to have an anti-inflammatory effect and a growth inhibitory effect on microorganisms.

3) Camphor: Extracts that relieve skin itch, relieve stress headaches and neuralgia, treat colds, bronchitis, arthritis, strong antifungal effect, and use solids as anti-gompies and insecticides for base insect repellent.

4) Fenchol: gives off pine

5) Borneol: Used as a soft analgesic, preservative, antiviral, antiperspirant, redness.

6) p, alpha-Dimethylstyrene: Used as an aromatic and flavoring agent.

7) Myrtenol: Serves as a signaling pathway for receptors involved in the treatment and pain delivery of effective immune inflammatory diseases while scenting grass, camphor, and inhibiting the migration of inflammatory mediator cells.

8) Carveol: strong tonic, gust, excitement, antibacterial action.

9) Carbon (Carvone): It is responsible for removing breast odor and fish smell.

10) Benzaldehyde: It shows antibacterial effect like ethanol, which is more toxic than ethanol, and it has the effect of treating central nervous system activity and cancer.

11) d-Fenchone: Synthetic flavoring substance and adjuvant, used as a flavoring additive in food and beverages.

In the step of preparing the highly functional high-concentrated lime Bordeaux solution and the complexed lime solution of the production method, conventional Bordeaux solution is necessarily used as a calcium source, but in the present invention, as well as quicklime (CaO) as well as hydrated lime (Ca (OH) ₂ ) And calcium carbonate (CaCO ₃ ) and the like also have usable features.

In the case of copper sulfate solution in the high-functionality highly concentrated lime boron solution and its preparation method, the copper sulfate solution is prepared by dissolving the amount of copper sulfate required for concentration to a desired concentration in water or another solvent, and the amount of copper sulfate required for concentration to the desired concentration The high concentration of Bordeaux liquid depends on whether it is a higher amount of lime than lime sulfate and a higher amount of lime. Basically, the amount of calcium source determined in the step of preparing the complexed lime solution and the same amount of copper sulfate is dissolved.

In addition, the copper sulfate solution in the highly concentrated lime Bordeaux solution and its preparation method is a solvent containing a phytoncide component instead of water as a solvent to dissolve copper sulfate in order to prepare a 'bordea solution' applicable to various diseases and pesticides, or a phytoncide essence in a microcapsule It is characterized by using, or mixing them.

In the method for preparing a highly concentrated multifunctional bordeaux solution of the present invention, in step (3), the copper sulfate solution prepared in step (2) is slowly added to the complexed lime solution prepared in step (1). It is characterized by producing a 'Bordeaux liquid'.

In the method for producing a highly concentrated and versatile Bordeaux liquid, the mixing of the complexed lime solution prepared in step (1) and the copper sulfate solution prepared in step (2) is required in principle to mix the same weight ratio. Depending on the mixing ratio of the two solutions can be selectively controlled.

Bordeaux liquid in the present invention refers to a highly concentrated solution, it is possible to concentrate at a concentration of 20 times or more on the basis of 8-8 formula, but preferably 5 to 10 times the concentration for the stability of the prepared solution.

In addition, when spraying the Bordeaux liquid of the present invention to the crop can be used to dilute 200 times to 500 times depending on the crop, it is usually preferred to use 500 times dilution.

The highly concentrated multifunctional 'Bordeaux liquid' prepared in the present invention has a pH of 8-9 due to the use of an acidic chelating agent, unlike the conventional Bordeaux liquid having an alkaline pH of 11-12 with the use of a complexing agent. It can be lowered to such an extent that, since the effect of copper can be effectively expressed under basicity, a small amount of an alkali component can be added if necessary. The alkali component is preferably characterized in that a small amount of NaOH or KOH can be added.

Bordeaux concentrate of the present invention prepared as described above is completely dissolved in lime, lime powder does not remain, and excellent calcium supply to the crop to prevent various physiological disorders, while being present in high concentration to minimize the toxicity of copper sulfate There is little harm, so it can be applied to most crops and is effective against a wide range of pathogens. In addition, the Bordeaux concentrate is easy to use, does not leave a cloudy residue (lime powder) on the leaves and fruits of plants, crops, etc. does not lower the value of the product, and can maintain the color, state, efficacy at the time of manufacture even if stored for a long time In addition to the prevention of the disease can be seen a significant healing effect after the onset of the disease.

In addition, Bordeaux liquid of the present invention can be mixed spraying of environmentally friendly organic agricultural materials (mainly pest inhibitors), which could not be added due to serious weakness of the prior art, and can be sprayed at any time regardless of the time of flowering, since lime powder does not have to concern the flowers. Has the advantage.

In addition, if the existing Bordeaux liquid rains after rain or after 1 week of spraying, when the external temperature is 30 ℃ or more during spraying (wet leaf phenomenon) occurred, Bordeaux liquid of the present invention is weak if not rain within 24 hours after spraying It does not occur and can be sprayed regardless of the outside temperature. In addition, the existing Bordeaux solution can cause respiratory failure by inhaling fine lime powder into the respiratory tract when spraying medicine, and not only could cause eye damage or visual impairment due to lime powder on the eyes, The Bordeaux solution of the present invention is exposed to considerable difficulties and risks because it may cause disease, but the Bordeaux solution of the present invention is a complete liquid phase without any fine powder and there is no such concern.

Bordeaux liquid of the present invention can be appropriately selected and adjusted the number and quantity of the plants, crops and the like, as appropriate, and can be spread, and the method can also be selected and carried out according to a conventional method.

Hereinafter, the present invention will be described in more detail with reference to the following examples. These examples are for illustrative purposes only and are not intended to limit the protection scope of the invention.
