초록

본 연구는 에스필과 수산화동의 혼용에 의한 오이, 토마토, 고추의 흰가루병에 대한 방제 효과를 구명하고자 수행하였다. 오이 흰가루병에서 에스필과 수산화동의 혼용 처리는 4 : 1 혼용처리구에서 발병엽률 18.9%와 방제효과 69.9%, 8 : 1 혼용 처리구에서 발병엽률 18.1%와 방제효과 71.1%로 가장 효과적이었다. 토마토 흰가루병에서 에스필과 수산화동의 혼용 처리는 4 : 1 혼용 처리구에서 발병엽률 12.4%와 방제효과 85.3%, 8 : 1 혼용 처리구에서 발병엽률 14.3%와 방제효과 83.0%로 가장 효과적이었다. 고추 흰가루병에서 에스필과 수산화동의 혼용 처리는 4 : 1 혼용 처리구에서 발병엽률 17.7%와 방제효과 76.4%로 가장 효과적이었다. 이상의 결과를 종합할 때 에스필과 수산화동 혼용처리에 의한 오이와 토마토 흰가루병에 대한 방제 효과는 4 : 1 혹은 8 : 1 혼용 처리가 가장 효과적이고, 고추 흰가루병에서는 4 : 1 혼용 처리가 가장 효과적인 방제 방법으로 구명되었다.

This research was performed to examine the effects of mixed espil and copper hydroxide for powdery mildew prevention on cucumber, tomato and pepper. On prevention effect for powdery mildew on cucumber, results revealed that mixed espil and copper hydroxide with a ratio of 4 : 1, disease incidence rate was 18.9% and prevention effect was 69.9%. Another treatment with a ratio of 8 : 1 showed an disease incidence rate of 18.1% and prevention effect of 71.1%, thus, showed great effectiveness. For powdery mildew on tomato, espil and copper hydroxide were mixed using the ratio 4 : 1, results showed an disease incidence rate of 12.4% and prevention effect of 85.3%. Treatment using the ratio of 8 : 1, results showed an disease incidence rate of 14.3% and prevention effect of 83.0%, thus, showed great effectiveness. For powdery mildew on redpepper, espil and copper hydroxide were mixed using the ratio of 4 : 1 with results showed disease incidence rate of 17.7% and prevention effect of 83.0%. From the results, this treatment is the most effective with the lowest attack rate and highest prevention effect. Deducing from the study, it was found out that using mixed espil and copper hydroxide using the ratios 4 : 1 or 8 : 1 are the most effective method for powdery mildew prevention. Mixed ratio of 4 : 1 or 8 : 1 was most effective for preventing powdery mildew on cucumber and tomato, while the espil and copper hydroxide ratio of 4 : 1 was the most effective method for powdery mildew prevention on pepper.
