Description

미산성 차아염소산수를 함유하는 식물병 방제용 조성물 및 이를 이용한 식물병 방제 방법{Composition containing slightly acidic hypochlorous water for plant diseases and method for controlling plant diseases using the same}TECHNICAL FIELD The present invention relates to a composition for controlling plant diseases, which contains micro-hypochlorous acid water, and a method for controlling plant diseases using the same.

본 발명은 미산성 차아염소산수를 활성성분으로 하는 식물병 방제용 조성물 및 이를 이용한 방제 방법에 관한 것이다.The present invention relates to a composition for controlling plant diseases, which contains hypochlorous acid as a active ingredient, and a method of controlling the plant disease.

물을 전기분해하면 양극에서는 산성전해수가 생성되고, 음극에서는 알칼리성전해수가 생성되는데, 이러한 물에 소금이나 염화칼륨을 첨가하여 전해한 pH가 2.7 이하의 산성전해수는 세균, 곰팡이, 바이러스 등 미생물을 순식간에 살균할 수 있는 차아염소산(HOCl)을 함유하고 있어 식품산업의 위생관리를 위한 소독제, 농업분야의 작물병해를 일으키는 병원성 미생물의 제어에 이용되고 있다. 특히, 산성 전해수는 인체에 거의 무해하고, 잔류하지 않아 채소, 과일, 화훼 등의 농업분야에 있어서 농약의 사용량을 감소시키며, 친환경적인 작물재배를 위하여 개발된 다양한 적용방법들이 그 활용대상을 넓히고 있다. 하지만 병원성 미생물의 살균과 병해 발생을 예방하기 위하여 작물의 잎과 줄기에 산성전해수를 살포하게 되면 잎과 줄기의 큐티클층으로 인해 잎과 줄기를 충분히 적시지 못하고 흘러 떨어지게 되고 붙어있는 것도 곧 햇빛과 공기에 분해되어 지속성이 유지되지 못하기 때문에, 산성전해수는 강한 살균력을 가지고 있음에도 불구하고 농약살균제에 비하여 방제가가 낮게 나타나는 문제점이 있었다.Acid electrolytic water with a pH of 2.7 or less, which is electrolyzed by adding salt or potassium chloride to the water, is capable of rapidly producing microorganisms such as bacteria, fungi, and viruses It contains sterilizable hypochlorous acid (HOCl), which is used to control hygienic sanitation in the food industry and to control pathogenic microorganisms that cause crop disease in the agricultural sector. In particular, acidic electrolytic water is virtually harmless to the human body, and does not remain in use, thus reducing the amount of pesticide used in agricultural fields such as vegetables, fruits and flowers, and various application methods developed for cultivating environmentally friendly crops . However, when acidic electrolytic water is sprayed on the leaves and stems of the crops to prevent the pathogenic microbes from being sterilized and diseased, the leaves and stems of the leaves and stems are not sufficiently wetted by the cuticle layer and fall off. , The acidic electrolytic water has a strong sterilizing power, but has a problem in that the control amount is lower than that of the pesticide disinfectant.

차아염소산수는 차아염소산(HOCl)이 함유된 수용액으로서, 전해질의 종류와 전해에 사용하는 전해조의 전극 간 이온투과 격막의 유무에 따라 생성되는 차아염소산수의 성상이 다르게 된다. 0.2% 이하의 염화나트륨용액을 유격막전해조에서 전해하면, 양극측에서는 pH 2.7 이하의 강산성 차아염소산수가 생성되고, 2 내지 6%의 희염산수를 무격막전해조에서 전해하면 pH 5.0 내지 6.0의 pH영역을 갖는 미산성차아염소산수가 생성된다.The hypochlorous acid water is an aqueous solution containing hypochlorous acid (HOCl). The characteristics of the hypochlorous acid generated are different depending on the type of the electrolyte and the presence or absence of the ion permeable diaphragm between the electrodes of the electrolytic bath used for electrolysis. Strongly acidic hypochlorous acid water having a pH of 2.7 or less is produced on the anode side when a sodium chloride solution of 0.2% or less is electrolyzed in a cathode membrane electrolytic cell, and a pH range of 5.0 to 6.0 is obtained when 2 to 6% Resulting in a slightly acidic hypochlorous acid water.

무격막전해조 내에서 염산은 하기 반응식 1에서 보이는 바와 같이 수소이온과 염소이온으로 전해되어 수소이온은 음극측에서 환원되어 수소로 되고 염소이온은 양극측에서 산화되어 염소로 된다.Hydrochloric acid in the seawater electrolytic cell is electrolyzed with hydrogen ions and chlorine ions as shown in the following reaction formula 1, and the hydrogen ions are reduced at the cathode side to become hydrogen, and the chloride ions are oxidized to chlorine at the anode side.

(반응식 1)(Scheme 1)

염산의 전해 : 2HCl → 2H+ + 2Cl- Electrolysis of hydrochloric acid: 2HCl -> 2H + + 2Cl -

양극 반응 : 2H+ + 2e → H2 Anode reaction: 2H + + 2e - & gt ; H 2

음극 반응 : 2Cl → Cl2 + 2e
Cathode reaction: 2Cl → Cl 2 + 2e

염소는 물에 용해하여 고농도염소용액을 생성하게 되는데 상기 고농도염소용액은 pH 0.7내지 1.5내로서 유효염소의 대부분이 염소이고 약간의 차아염소산으로 형성된다. pH 1의 고농도염소용액은 염소 대 차아염소산 비율이 22:1 정도이고 염소 일부가 물과 반응하여 생성된 염산, 미분해 염산 등을 함유하고 있다.The chlorine is dissolved in water to produce a high concentration chlorine solution. The high concentration chlorine solution has a pH within the range of 0.7 to 1.5, and most of the available chlorine is chlorine and is formed with a slight amount of hypochlorous acid. The high concentration chlorine solution of pH 1 has a chlorine to hypochlorous acid ratio of about 22: 1 and contains a part of chlorine reacted with water to produce hydrochloric acid and undissolved hydrochloric acid.

차아염소산수는 주로 그 용도가 살균소독과 소취이며, pH 2.7 이하의 강산성 차아염소산수와 2.7 이상 5.0 미만의 약산성 차아염소산수 및 pH 5.O 내지 6.0의 미산성 차아염소산수로 구분된다.The hypochlorous acid water is mainly used for disinfection and deodorization. It is divided into strongly acidic hypochlorous acid having a pH of 2.7 or less, slightly acidic hypochlorous acid having a pH of less than 2.7 and less than 5.0, and hypochlorous acid having a pH of 5. to 6.0.

강산성 차아염소산수는 유효염소의 성분구성이 염소(Cl2, 액상)가 15 내지 20%, 차아염소산이 80 내지 85%로 되어 있으며, 미산성 차아염소산수는 2% 이내의 차아염소산이온(OCl-)과 98 내지 100%의 차아염소산으로 되어있고, 염소를 함유하지 않고 있는 것을 특징으로 한다. pH 6.0 이상이 되면 차아염소산이온의 생성이 많아져 살균력이 약화된다.The strong acidic hypochlorous acid water has a constituent constituent of chlorine (Cl 2 , liquid phase) of 15 to 20% and hypochlorous acid of 80 to 85%, and the number of hypochlorous acid which is not acidic is less than 2% of hypochlorite ion - ) and 98 to 100% of hypochlorous acid, and does not contain chlorine. At pH 6.0 or higher, the production of hypochlorous acid ion is increased and the sterilizing power is weakened.

강산성 차아염소산수와 pH 5.0 이하의 약산성 차아염소산수는 유효염소 구성 성분 중에 분자상 염소를 포함하고 있기 때문에 염소 자극취와 금속부식성이 있으며, pH가 낮기 때문에 보관 중에 하기 반응식 2에서 보이는 바와 같이 반응이 좌측으로 이행하여 유효염소성분인 차아염소산(HOCl)이 염소로 되어 휘발하기 때문에 차아염소산수의 유효염소농도가 저하됨으로 인하여 보관 안정성이 낮아지는 결점이 있다.Strongly acidic hypochlorous acid water and weakly acidic hypochlorous acid having a pH of less than 5.0 have a chlorine scent and a metal corrosive property because they contain molecular chlorine in the effective chlorine constituent, (HOCl), which is an effective chlorine component, is volatilized as chlorine, and thus the effective chlorine concentration of hypochlorous acid water is lowered, resulting in a drawback that storage stability is lowered.

대한민국 등록특허 제0684357에는 식염수를 이용해 만든 강산성 전해수 및 강알칼리 전해수를 이용해 신선편이 채소류의 유해세균 저감화를 위한 효과적인 항균방법이 개시되어 있다. Korean Patent No. 0684357 discloses an effective antibacterial method for reducing harmful bacteria in fresh-cut vegetables using strong acid electrolytic water and strong alkaline electrolytic water made using saline.

한편, 재배현장에 있어서 발생하는 많은 식물병들이 주변에서 사용되는 농업용수를 매개로 발생되는 것으로 알려져 있는데 특히 수매전반을 통해 병을 전파시키는 세균인 토마토청고병균과 역병을 일으키는 곰팡이류의 고추역병균 발생은 농업용수 및 양액을 통해 병을 전반시키며 매우 큰 피해를 준다. 이와 관련 오염된 농업용수 및 수경재배시 사용되는 양액의 병방제에 사용되는 기존 농약은 그 적용대상이 매우 한정되어지는데 광범위한 병원균들을 대상으로 살균효과가 나타나는 미산성 차아염소산수의 새로운 병억제 특성 규명은 친환경적 살균제로서의 활용가치를 매우 높일 것으로 본다. On the other hand, it is known that many plant diseases occurring in the cultivation field are generated through agricultural water used in the vicinity. In particular, it is known that the tomato bacteria that cause the disease propagation through the whole purchase process and the mold bacteria that cause the plague Is very dangerous because it causes the disease to spread through agricultural water and nutrient solution. Conventional pesticides used in polluted agricultural water and nutrient solution used in hydroponic cultivation are very limited in their application. New pesticidal properties of hypochlorous acid water, which has a germicidal effect on a wide range of pathogens, Will greatly enhance the value of its use as an environmentally friendly disinfectant.

또한, 작물재배시 발생하는 병원균을 대상으로 미산성전해수의 살포시 표면장력의 감소와 살포면적의 확장이 가능하면 방제효과 증진을 가져와 부가가치가 높은 식물 재배 생산성을 향상시킬 수 있다.
In addition, it is possible to reduce the surface tension and spread the spraying area of the pathogenic microorganisms in the cultivation of crops, thereby improving the control effect and improving the productivity of the plant with high added value.

상기 비이온성 계면활성제는 소르비탄 지방산 에스테르, 폴리옥시에틸렌소르비탄 지방산 에스테르, 자당 지방산 에스테르, 폴리옥시에틸렌 지방산 에스테르, 폴리옥시에틸렌수지산에스테르, 폴리옥시에틸렌 지방산 디에스테르, 폴리옥시에틸렌피마자유, 폴리옥시에틸렌알킬에테르, 폴리옥시에틸렌알킬페닐에테르, 폴리옥시에틸렌디알킬페닐에테르, 폴리옥시에틸렌알킬페닐에테르의 포르말린 축합물, 폴리옥시에틸렌폴리옥시프로필렌 블록폴리머, 알킬폴리옥시에틸렌폴리옥시프로필렌 블록폴리머에테르, 알킬페닐폴리옥시에틸렌폴리옥시프로필렌 블록폴리머에테르, 폴리옥시에틸렌알킬아민, 폴리옥시에틸렌 지방산 아미드, 폴리옥시에틸렌비스페닐에테르, 폴리옥시알킬렌벤질페닐에테르, 폴리옥시알킬렌스티릴페닐에테르 및 폴리에틸렌글리콜-p - 이소옥틸페닐에테르 중에서 선택되는 어느 하나 또는 둘 이상의 혼합물을 포함한다. The nonionic surfactant may be selected from the group consisting of sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, sucrose fatty acid esters, polyoxyethylene fatty acid esters, polyoxyethylene resin acid esters, polyoxyethylene fatty acid diesters, polyoxyethylene castor oil, poly Polyoxyethylene alkylphenyl ether, polyoxyethylene dialkyl phenyl ether, formalin condensate of polyoxyethylene alkyl phenyl ether, polyoxyethylene polyoxypropylene block polymer, alkyl polyoxyethylene polyoxypropylene block polymer ether , Alkylphenyl polyoxyethylene polyoxypropylene block polymer ether, polyoxyethylene alkylamine, polyoxyethylene fatty acid amide, polyoxyethylene biphenyl ether, polyoxyalkylene benzyl phenyl ether, polyoxyalkylene triester phenyl ether and polyethylene glycol Cole- p -iso-octylphenyl ether, and mixtures thereof.

본 발명의 일 실시예에 따른 식물병 방제용 조성물에 있어서, 상기 비이온성 계면활성제를 대체하여 음이온성 계면활성제, 양이온성 계면활성제 또는 양성 계면활성제를 사용할 수도 있겠지만, 이들 계면활성제는 산성 전해수의 유효 염소 농도 및 산화환원전위를 저하시키는 경향이 있어, 이들에 비하여 비이온성 계면활성제를 사용하는 것이 식물병 방제 성능에 현저한 효과를 발현할 수 있으며, 특히, 차아염소산수와의 조합으로 그 상승효과는 월등하다. In the composition for controlling plant diseases according to an embodiment of the present invention, anionic surfactant, cationic surfactant or amphoteric surfactant may be used instead of the nonionic surfactant. However, these surfactants are effective for acidic electrolytic water Chlorine concentration, and oxidation-reduction potential. In contrast, use of a non-ionic surfactant can exert a remarkable effect on the plant disease control performance, and in particular, in combination with hypochlorous acid water, Be superior.
