초록

본 연구는 온실 내 오이재배에서 크게 문제가 되는 흰가루병의 친환경적 방제를 위한 방법으로 올레산의 사용에 대한 효과와 올레산 처리 시 적정 농도를 구명하기 위해 수행되었다. 실험은 상명대학교 플라스틱 실험온실에서 '백봉다다기(농우바이오, 한국)'를 사용하여 수행하였다. 오이의 흰가루병에 대한 올레산의 처리효과와 적정농도 구명을 위한 실험은 무처리구를 대조구로 하고 올레산 2000 ppm, 4000 ppm, 6000 ppm, 8000 ppm을 각각 처리하고 병피해도, 병반면적율, 방제가, 약해피해도 및 약해면적율을 조사하였다. 방제가는 처리 3일 후에 조사했으며, 재발생 조사는 55일간 수행하였다. 시설 내 주야간 온도는 $23/15^{\circ}C$로 조절하였고, 상대습도는 조절하지 않았다. 오이의 흰가루병 방제에 올레산은 매우 효과적인 것으로 나타나서 화학적 방제를 대체할 수 있는 좋은 친환경 유기농자재로 판단되었다. 올레산은 2000 ppm 농도로 분무하는 것이 방제가가 높으며, 약해가 발생하지 않는 것으로 조사되었다. 또한 흰가루병의 예방 및 재발생 방지를 위해 3주에 1회씩 올레산을 분무하는 것이 좋을 것으로 사료된다.

We experimented with the effect of oleic acid and its appropriate concentration to prevent powdery mildew eco-friendly in a cucumber greenhouse cultivation. 'Baekbongdadaki' (Nongwoo Bio. co. Korea) was treated in the plastic greenhouse at Sangmyung University. We treated four levels of concentration of oleic acid, which were 0, 2000, 4000, 6000, and 8000 ppm. There were investigated diseased severity, diseased leaf area, control value, and pesticide injury. The degree of control values by oleic acid treatments was investigated at 3 days after treatment. The recurrence of powdery mildew was checked for 55 days. The day and night temperature in the greenhouse were controlled to 23 and $15^{\circ}C$ respectively. The humidity inside the greenhouse was not controlled to prevent outbreak of the disease. From the experimental results, oleic acid was very efficient to control powdery mildew. 2000 ppm of oleic acid was shown to be the most control efficiency without any pesticide injury. The recommended method to treat it was to spray three times every 3 weeks.
