Description
본 발명은 5-클로로인돌을 유효성분으로 함유하는 소나무재선충병 방제용 조성물 및 이의 용도에 관한 것이다.The present invention relates to a composition for controlling pine tree nematode disease containing 5-chloroindole as an active ingredient, and a use thereof.
소나무재선충병은 소나무에 심각한 피해를 일으켜 국제검역대상 제1호로 분류되는 식물병으로서, 1900년대에 일본에서 처음 발생하였으며, 우리나라에서는 1988년 부산 금정산에서 최초로 소나무재선충이 확인되었다. 소나무재선충(Bursaphelenchus xylophilus)은 소나무를 비롯하여 전나무(Abies), 가문비나무(Picea), 미송(Pseudotsuga), 이갈나무(Lalix), 개잎갈나무(Cedrus) 및 철삼(Tsuga spp.) 속의 기주에서 증식하여 나무를 죽이는 병원체로 스스로 이동할 능력이 없으며 매개충인 솔수염하늘소(Monochamus alternatus)를 통해 이동하여 기주식물을 감염시킨다. 현재 부산, 울산 및 경남지역에서 대규모의 피해지가 발생하고 있으며 그 외에도 전남 목포, 제주도, 강릉 및 경기도 광주지역까지 그 피해가 확산되고 있다.Pine tree nematode disease is a plant disease that causes serious damage to pine trees and is classified as the No. 1 subject of international quarantine. Pine nematode ( Bursaphelenchus xylophilus ) grows on the host of the genus Abies, Spruce (Picea), Pseudotsuga, Lalix, Cedrus and Tsuga spp. It is a pathogen that kills trees, and does not have the ability to move on its own. It infects host plants by moving through the vector, Monochamus alternatus . Currently, large-scale damaged areas are occurring in Busan, Ulsan and Gyeongnam areas, and the damage is spreading to Mokpo, Jeju Island, Gangneung and Gwangju, Gyeonggi-do.
소나무재선충 방제 방법에는 소나무재선충 자체를 방제하는 방법과 매개충인 솔수염하늘소를 방제하는 방법이 있다. 소나무재선충 자체를 방제하는 방법은 아바멕틴(abamectin), 에마멕틴 벤조에이트(emamectin benzoate), 모란텔 타르트레이트(morantel tartrate) 등의 살선충제를 소나무에 수간주사하여 소나무재선충의 침입 및 증식을 막는 방법으로, 사전예방에 효과가 있으나 산림 내에서 작업이 어려우며, 수간주입용 방제약제들이 고가여서 비용이 많이 드는 단점이 있다. 또한, 환경에 대한 위해성의 우려가 있어 저비용으로 환경 위해성이 낮거나 없는 방제약제에 대한 요구도가 증가되고 있는 실정이다. 매개충인 솔수염하늘소를 방제하는 방법은 매개충의 우화 및 성충 활동 시기에 살충제를 항공 살포하거나 매개충의 산란목을 벌채, 훈증, 소각시키는 방법이 있다. 그러나 소나무재선충 감염목, 매개충 산란목을 처리하는 방법은 소나무재선충병의 확산을 방지할 수는 있으나 소나무재선충 감염 전에 방제하는 방법으로는 적절하지 않으며 현재까지는 살선충제의 수간주사가 가장 현실적인 방법으로 알려져있다. 최근에는 살선충제 수간주사의 단점을 보완하기 위하여 화학농약을 대체하는 소나무재선충 살선충 물질에 대한 연구가 활발히 진행되고 있으며, 그 중 미생물로부터 소나무재선충 방제에 활성을 가지는 물질을 찾는 연구가 중요한 방법으로 사료되고 있다.There are two methods of controlling pine tree nematodes, a method of controlling pine tree nematodes itself, and a method of controlling pine tree nematode. The method of controlling the pine tree nematodes itself is to prevent the invasion and proliferation of pine tree nematodes by injecting nematodes such as abamectin, emamectin benzoate, and morantel tartrate into pine trees. As a method, it is effective in prevention, but it is difficult to work in the forest, and there are disadvantages that the cost is high due to the high cost of control agents for bestiality injection. In addition, there is a concern about environmental risks, so there is an increasing demand for control agents with low or no environmental risks at low cost. The method of controlling the insect vector, the brush bearded sky cattle, is to spray the insecticide by air during the fable and the adult activity period of the vector insect, or the method of cutting, fumigation, and incineration of the spawning tree of the vector insect. However, the method of treating pine tree nematode infected trees and vector insect spawning trees can prevent the spread of pine tree nematode disease, but it is not appropriate as a method of controlling before pine tree nematode infection. Until now, bestial injection of nematode nematodes is known as the most realistic method. have. Recently, in order to compensate for the shortcomings of the nematode injection, studies on the nematode nematode substances that replace chemical pesticides are being actively conducted, and among them, the study of finding substances that have activity in controlling pine nematodes from microorganisms is an important method. It is considered to be.
따라서, 본 발명에서는 소나무재선충병의 방제를 위해 살재선충효과가 좋은 인돌화합물을 소나무 재선충방제에 이용하고자한다.Accordingly, in the present invention, an indole compound having a good insecticidal nematode effect is used for controlling pine tree nematodes for the control of pine tree nematodes.

재료 및 방법Materials and methods
1. 재선충 배양1. Re-nematode culture
소나무재선충병의 원인인 재선충(Bursaphelenchus xylophilus)을 국립산림과학원에서 분양받아 잿빛곰팡이병균(Botrytis cinerea)이 배양된 PDA(potato dextrose agar) 평판배지에 계대배양하여 시험선충으로 사용하였다.
Bursaphelenchus xylophilus , the cause of pine nematode disease , was pre-sold from the National Institute of Forest Science and was subcultured on a PDA (potato dextrose agar) plate medium in which Botrytis cinerea was cultured and used as a test nematode.
2. 살재선충 효과 실험2. Experiment on the effect of nematodes
살재선충 효과는 7일, 8일차의 재선충을 사용하여 분석하였다. 최종처리농도가 100 ppm, 10 ppm 및 1 ppm이 되도록 5-클로로인돌을 메탄올에 녹여 준비한 5㎕와 95㎕의 선충용액(30~40여 마리 선충 포함)을 96-well Microtest™ Tissue Culture Plate의 각 웰에 3반복으로 실험하였다. 살선충 활성은 상기와 같이 5-클로로인돌을 처리한 96-well Plate를 24℃ 항온기에 넣고 반응시켜 24시간 후 해부현미경 하에서 관찰하여, 곧게 경직되고 움직이지 않는 선충은 죽은 선충으로, 유연하고 움직임이 있는 선충은 산 선충으로 간주하여 각각의 개체수를 세어 살선충율을 조사하였다.
The effect of the nematode was analyzed using the nematodes on the 7th and 8th days. 5 µl and 95 µl of nematode solution (including 30-40 nematodes) prepared by dissolving 5-chloroindole in methanol so that the final treatment concentrations are 100 ppm, 10 ppm and 1 ppm are added to the 96-well Microtest™ Tissue Culture Plate. Each well was tested in triplicate. Nematode activity was observed under a dissecting microscope after 24 hours by placing a 96-well plate treated with 5-chloroindole as described above in a thermostat at 24°C. The nematodes that are stiff and not moving are dead nematodes, which are flexible and move. The nematodes with this were regarded as live nematodes, and the number of each individual was counted to investigate the rate of nematode.
실시예 1. 살재선충 효과 검정결과Example 1. Results of testing the effect of the nematode nematode
5-클로로인돌의 소나무재선충에 대한 방제 효과를 확인하기 위해 살선충활성 평가 실험을 진행하였다. 아바멕틴(abamectin)은 살재선충활성 평가에 대한 양성 대조군으로 사용되었으며, 메탄올을 음성 대조군으로 사용하였다. 살재선충 효과 검정결과, 5-클로로인돌은 100 ppm의 농도에서 90% 치사율을 보였으며, 10 ppm의 농도에서도 80% 치사율을 보여, 대조구인 아바멕틴 100 ppm(㎍/㎖)보다 우수한 살재선충 활성을 보였다(도 2 및 도 3).In order to confirm the control effect of 5-chloroindole against pine nematodes, a nematode activity evaluation experiment was conducted. Abamectin was used as a positive control for the evaluation of nematode activity, and methanol was used as a negative control. As a result of the test for the nematode effect, 5-chloroindole showed 90% mortality at the concentration of 100 ppm, and 80% mortality at the concentration of 10 ppm, which was superior to the control, abamectin, 100 ppm (㎍/㎖). Showed (Fig. 2 and Fig. 3).
