Abstract

Kiwi plague is a serious blight caused by mildew. According to the method for controlling a plague carried out by the present inventors in Sacheon, Koheung and Kosung farms, a method for controlling pathogenic bacteria based on soil disinfection carried out in combination with foliage spray is shown to maximize the effect of controlling a plague. Particularly, according to the present invention, when an agrochemical is inpoured after spraying water sufficiently 12 hours before the agrochemical inpouring, while carrying out foliage spray at the same time, the effect of controlling a plague is increased to 96.6%. Therefore, it can be seen that the method is the most preferred method for controlling a plague. In addition, when foliage spray is carried out twice per month after May, and a mixture of phosphorus acid with copper sulfate is used continuously until the harvest time, it is possible to control a plague to 95% or higher.

본 발명은 키위 역병 방제용 농약 조성물 및 그 제조방법에 관한 것으로, 더욱 상세하게는 본 발명은 아인산과 황산동을 포함하는 키위 역병 방제용 조성물과 그 제조방법 및 그 방제방법에 관한 것이다.The present invention relates to an agrochemical composition for controlling kiwi blight and a method for preparing the same, and more particularly, the present invention relates to a composition for controlling kiwi blight comprising phosphorous acid and copper sulfate, a method for preparing the same, and a method for controlling the same.

키위(일명 참다래) 역병의 병원균은 곰팡이의 일종인 피토프토라 드레취스레리(Phytophthora drechsleri)에 의해 발생하는 전염병으로 토양 중의 수분이 많은 조건에서 활동력이 왕성하여 피해가 극심하다. 따라서 배수가 불량한 과수원에서 주로 발생하고, 일반 과수원에서도 배수가 불량한 자리에서 흔히 발생한다. 이렇게 역병균이 물을 좋아하는 관계로 역병의 피해를 습해로 오인해 왔다.The pathogen of kiwi (also known as blue sputum) plague is an infectious disease caused by Phytophthora drechsleri, a type of fungus, and its damage is severe due to its active force under high moisture conditions in the soil. Therefore, it occurs mainly in orchards with poor drainage, and it often occurs in places with poor drainage even in general orchards. In this way, because the plague bacteria love water, the damage of the plague has been mistaken for wetness.

키위 역병은 뿌리에서 감염되어 물관부를 타고 올라가 심부를 부패시키기 때문에 수분과 양분 이동이 제대로 이루어지지 않아 키위 식물을 고사시킨다. 병변 초기에는 잎 바깥 쪽이 황화되고 잎이 말리거나 탈색되면서 낙엽과 함께 측지부터 말라 들어가는 증상을 보인다. 병변 진행 후 키위 식물 뿌리를 파보면 뿌리가 완전히 갈변되어 있는 증상을 볼 수 있고, 줄기의 껍질을 벗겨보면 물관부가 갈변되고 심할 경우에는 심부도 부패되어 있는 것을 볼 수 있다. 그러나 줄기의 겉에서는 별 다른 증상을 보이지 않기 때문에 키위 재배 농민이나 관리자들이 소홀히 하는 경향이 있다.Kiwi blight is infected from the roots and rises up the water pipe and causes the core to rot. Therefore, moisture and nutrients are not properly transferred, causing the kiwi plant to die. In the early stage of the lesion, the outside of the leaves is yellowed and the leaves are dried or bleached, showing symptoms of drying from the lateral branches along with fallen leaves. If you dig the kiwi roots after the lesion progression, you can see the symptoms that the roots are completely browned. If you peel the stems, the water tube part is browned, and in severe cases, the deep part is also decayed. However, since the stem does not show any other symptoms, kiwi farmers and managers tend to neglect it.

키위 역병과 습해의 차이점은 습해를 받은 경우 배수 문제만 해결되면 회복이 가능하지만, 역병이 걸린 경우는 거의 회복이 불가능하다. 키위 뿌리의 침수시간이 길수록 역병균에 감염율은 높아지고, 96시간 이상 침수시켰을 때는 새뿌리 생성이 안되어 회복이 불가능하다는 것이 확인되었다.The difference between kiwi blight and moist damage is that if you receive moisture, you can recover only if the drainage problem is solved, but it is almost impossible to recover in the case of blight. It was confirmed that the longer the immersion time of kiwi roots, the higher the rate of infection with plague bacteria.

키위 역병은 방제보다는 우선 예방이 우선한다. 앞의 발생환경과 증상에서 설명한 바와 같이 키위 역병은 배수가 잘 되지 않는 조건에서만 발생하기 때문에 배수가 잘 되지 않는 과수원에서는 배수로를 깊게 파는 것이 최우선이고, 가능하면 배수가 불량한 지역에서는 재배를 피하는 것이 상책이다.Kiwi pestilence comes first with prevention over control. As described in the above outbreak environment and symptoms, kiwi blight occurs only under poor drainage conditions, so it is the top priority to dig deep drainage in poor drainage orchards, and avoid cultivation in areas with poor drainage if possible. to be.

키위 역병 방제를 위해서는 조기진단이 가장 중요하다. 왜냐하면, 잎이 잘리거나 낙엽이 될 정도가 되면, 뿌리의 대부분은 이미 부패되기 때문에 방제가 불가능하기 때문이다. 조기진단을 위해서는 작업자가 세심한 관찰을 통해 잎이 황화되는 것을 찾아내고, 그 나무의 뿌리를 파서 뿌리의 부패원인을 확인해야 한다.Early diagnosis is the most important for the control of kiwi blight. This is because, when the leaves are cut or become fallen leaves, most of the roots are already decayed, so control is impossible. For early diagnosis, the worker must detect the yellowing of leaves through careful observation, and dig the roots of the tree to determine the cause of the root decay.

한편, 키위 역병은 유묘기부터 전 생육기에 발생되며, 주로 뿌리와 땅 줄기부위에 발생 되지만 병원균이 빗물에 튀어 올라 열매 등의 지상부를 흔히 침해하기도 한다. 현재까지 3종의 역병균이 토마토 뿌리썩음역병을 일으키는 것으로 확인되었는데 균종류별, 재배품종별이 병증상은 매우 유사하다. 유묘기에 감염되면 그루 전체가 심하게 시들고 곧 죽으며, 생육중기나 후기에 감염되면 초기에는 아랫잎부터 약간황화되어 시들고 말라죽는다. 병든 그루의 땅가줄기와 굵은 뿌리는 수침상으로 썩으며 껍질을 벗겨 보면 줄기내부가 연한 갈색이나 암갈색으로 썩어있다. 간혹 지표면 가까이에 매달린 과실에도 수침상의 병반이 나타나 회갈색의 큰 원형병반으로 확대되어 썩으며, 다습한 환경에서 흰 곰팡이 균사체와 포자가 많이 형성된다.On the other hand, kiwi blight occurs from the seedling period to the entire growth period, and mainly occurs on the roots and stems of the ground, but pathogens splash in rainwater and often invade the above-ground areas such as fruits. Until now, 3 types of plague bacteria have been confirmed to cause tomato root rot plague, but the symptoms are very similar for each type of bacteria and cultivar. When infected during the seedling stage, the whole tree withers badly and dies soon. When infected in the middle or late growth stage, the lower leaves are slightly yellowed and withered and dried up at the beginning. The ground stem and thick roots of a diseased tree rot into a water bed, and when peeled, the inside of the stem is rotted in light brown or dark brown. Occasionally, water-needle-like lesions appear even in fruits hanging near the ground surface, enlarged and rot, into large gray-brown round lesions, and white fungal mycelium and spores are formed in a humid environment.

Phytophthora capsici, P. drechsleri tuck, P. megasperma drechsleri 및 P. infestans 등으로 알려진 토마토 뿌리썩음병을 일으키는 역병균은 4종이 확인되었다. 이들 모두 크로미스터계의 난균문에 속하며, 이들 중 고추역병균인 P. capsici의 병원성이 가장 강하다. P. drechsleri는 배추역병균과 형태적으로 유사한데 유두돌기가 없는 유주자낭은 주로 단생하며, 물속에서만 형성된다. 장타원 혹은 서양배 모양의 유주자낭은 길쭉하고 아래쪽이 가늘어지기도 한다. 유주자낭의 크기는 36∼70×26∼4㎛이며, 자웅이주체로 장란기의 직경은 22∼53㎛이다. P. megasperma는 자웅이주균으로 기주 식물체의 뿌리나 배양기에서 다량의 난포자를 형성하는데, 장란기의 직경은 40∼53㎛이다. 토마토 역병 방제용 미생물 균제는 국내 공개특허 10-2010-0085759호에 개시되어 있고, 또 고추역병 방제용 미생물 균제는 국내 특허공개 10-2003-0089846호에 개시되어 있다.Four plague bacteria that cause tomato root rot, known as Phytophthora capsici, P. drechsleri tuck, P. megasperma drechsleri, and P. infestans, were identified. All of them belong to the chromister family, and among them, P. capsici is the most pathogenic. P. drechsleri is morphologically similar to the cabbage blight bacteria, but the mimic aschia without papillary processes is usually single and is formed only in water. Long oval or pear-shaped yujujaang is elongated, and the lower part is also thin. The size of the zygomatic sac is 36∼70×26∼4㎛, and the diameter of the jangrangi is 22∼53㎛ with hermaphrodites. P. megasperma is a hermaphrodite bacterium that forms a large number of follicles in the roots or incubators of the host plant, and the diameter of the intestinal ovary is 40-53㎛. The microbial fungicide for controlling tomato blight is disclosed in Korean Patent Publication No. 10-2010-0085759, and the microbial fungator for controlling pepper blight is disclosed in Korean Patent Publication No. 10-2003-0089846.

일반적으로 상기 역병균들은 피해식물과 균사가 토양중에 잠복하여 월동함으로써 제1차 전염원이 되며 발병 후에는 병반상에 형성된 유주자에 의해 제2차 전염을 하게 된다. 유주자는 수분과 접촉하면 발아해서 포자를 방출하며 포자는 식물체의 기공을 통해 침입하게 된다. 시설에서는 이어짓기가 많이 행해지므로 노지보다 병원균이 많으나 비를 직접 맞지 않으므로 발생은 적다. 그러나 다습조건하에서는 잎표면에 이슬이 생겨 비에 젖은 것처럼 되는 까닭에 2차 감염이 많아진다. 양액재 배지에서는 양액 및 관수시 물을 따라 전염하며 유주자는 튀어올라 지상부에 발병하기도 하며, 공급되는 양액이 과다하여 과습되면 뿌리가 침수되어 병발생이 용이하여 진다. 한편, 살균되지 않은 배지경을 계속하여 사용하게 되면 다 발생하게 한다. 노지에서는 6월 초순부터 발생되며, 장마기 8, 9월에 발생이 심하다. In general, the pestilence bacteria become the primary source of infection by overwintering in the soil by lurking in the soil with the damaged plants and mycelium, and after the outbreak, the secondary infection is carried out by the migrants formed on the lesion. When migrants come into contact with moisture, they germinate and release spores, and spores invade through the pores of the plant. In the facility, there are more pathogens than in the open field because there is a lot of splicing, but the occurrence is less because it does not directly hit the rain. However, under high humidity conditions, dew is formed on the leaf surface and becomes wet with rain, resulting in increased secondary infection. In the nutrient solution medium, it is transmitted along the nutrient solution and water during irrigation, and the migrants splash and develop on the ground. If the nutrient solution supplied is excessive and over-humidified, the roots are flooded and disease is easily generated. On the other hand, if the unsterilized culture medium is continuously used, it will all occur. It occurs in the open field from early June, and the rainy season is severe in August and September.

토양이 장기간 과습하거나 배수가 불량하고 포장이 침수되면 병발생이 조장 된다. 병원균은 종자전염이 가능하나 대부분의 전염원은 토양에서 유입된다. 병원균은 병든 식물체의 조직에서 균사나 난포자 상태로 월동 후 다시 발아하여 1차전염원이 되는데 P. capsici와 P. drechsleri는 전국적으로 널리 퍼져 있고 매우 넓은 기주를 가지고 있다. P. capsici는 거의 모든 가지과와 박과 채소를 침해하며, P. drechsleri는 주로 박과 작물과 약초류를 침해한다. P.megasperma는 국내 일부 지역에서만 발생되었으며, 토마토에 대한 병원성도 다른 두 균에 비해 매우 미약하다.If the soil is excessively humid for a long period of time or if the drainage is poor and the pavement is flooded, disease is promoted. Pathogens can transmit seeds, but most of the transmission sources come from the soil. Pathogens germinate again after wintering in the state of hyphae or follicle in the tissues of diseased plants and become the primary source of transmission. P. capsici and P. drechsleri are widespread nationwide and have a very wide host. P. capsici invades almost all eggplant and gourd vegetables, while P. drechsleri primarily invades gourd crops and medicinal herbs. P. megasperma has occurred only in some regions of Korea, and its pathogenicity to tomatoes is also very weak compared to the other two bacteria.

그런데, 대체로 키위 역병은 상기한 바 곰팡이류인 Phytophthora drechsleri tuck에 의하여 발생되며 세균 Pseudomonas syringae에 의해서 발생되는 키위궤양병과 함께 키위나무를 죽여 결국 폐농에 이르게 하는 가장 피해가 심한 키위 병해이다. 처음에는 잎 바깥쪽이 황화되고 잎이 말리거나 탈색되면서 낙엽과 함께 측지부터 말라 들어가는 증상을 보인다(도 1). 이러한 나무의 뿌리를 파보면 뿌리가 완전히 갈변되어 있는 것을 볼 수 있고, 줄기의 껍질을 벗겨보면 물관부가 갈변되고 심할 경우에는 심부도 부패되어 있는 것을 볼 수 있다. 그러나 이와 같은 키위 역병에 대한 예방 및 치유를 위한 농약제제는 국내외에 선행기술 어디에도 발견할 수 없었다.However, kiwi blight is generally caused by the fungus Phytophthora drechsleri tuck, as described above, and is the most damaging kiwi disease that kills kiwi trees and eventually leads to lung farms along with kiwi ulcer disease caused by the bacteria Pseudomonas syringae. Initially, the outside of the leaves is yellowed and the leaves are curled or bleached, showing symptoms of drying from the lateral branches along with fallen leaves (Fig. 1). If you dig the roots of these trees, you can see that the roots are completely browned, and if you peel the trunks, the water tube part is browned, and in severe cases, the deep part is also decayed. However, pesticides for the prevention and cure of kiwi blight could not be found anywhere in the prior art at home and abroad.

따라서, 본 발명의 목적은 키위 역병 방제용 농약 조성물 및 그 제조방법을 제공하는 데 있다. 본 발명의 다른 목적은 상기 농약 조성물을 사용하여 키위 역병을 방제하는 방법을 제공한다.Accordingly, an object of the present invention is to provide a pesticide composition for controlling kiwi blight and a method for producing the same.

한편, 사천, 고흥, 고성 세 지역 모두 역병 방제를 위한 가장 바람직한 방법은 토양관주와 엽면살포를 3회 병행한 결과였는데 매우 만족할 만한 결과를 얻게 되었다.On the other hand, in all three areas of Sacheon, Goheung, and Goseong, the most desirable method for controlling pestilence was the result of performing soil drenching and foliar spraying three times, and very satisfactory results were obtained.

즉, 물을 약제관주전 약 12시간 전에 충분히 분무한 후 약제를 관주하고 동시에 엽면살포 함으로써 나무와 가지는 물론 약제가 관주되지 않은 사각지대가 거의 없는 약제처리방법이 방제가 96.6%로 역병발생을 방제하는 가장 좋은 방제 방법으로 확인되었다(표 7 ~ 표 9; 도 5 ~ 도 7).In other words, by spraying enough water about 12 hours before drug irrigation, then drenching the drug and spraying the foliar surface at the same time, the drug treatment method with almost no blind spots where the drug is not irrigated as well as the tree is 96.6% to control the outbreak It was identified as the best control method (Tables 7 to 9; FIGS. 5 to 7).

그러나 약제관주전 물을 분무할 때, 시설이 제대로 갖추어지지 않은 경우에는 물량을 두 배로 하여 일시에 관주하는 방법을 택할 수밖에 없었는데 두 번으로 나누어 관주하는 방법보다는 결과가 평균 92.5%로 낮게 나타났지만 이 방법도 차선의 방법으로 추정되었다.However, when spraying water before drug irrigation, if the facilities were not properly equipped, there was no choice but to double the amount of water and irrigation at a time.The result was lower than the method of dividing it into two at 92.5% on average, but this method. It was also estimated in the second best way.
