Abstract

This research was performed to examine the protective activities of the mixtures of pine oil and copper hydroxide against bacterial spot and anthracnose on pepper plants. As for bacterial spot, the treatment of pine oil alone displayed high disease incidence (59.6%) and low protective effect (28.9%). In comparison, the treatments of mixtures and copper hydroxide alone showed protective activities of 66.8-76.1%. The mixture of pine oil and copper hydroxide (4:1) suppressed the most effectively bacterial spot on pepper. On the other hand, the mixture of pine oil and copper hydroxide (4:1) also showed the strongest protective effect against pepper anthracnose among the 4 treatments tested; its disease incidence and disease control value were 49.8% and 41.7%, respectively. The other treatments showed low protective activities with control values of 7.4-17.1%. These results suggested that the mixture of pine oil and copper hydroxide (4:1) can be used for the environmental-friendly disease control of bacterial spot and anthracnose on pepper.

본 연구는 파인 오일과 수산화동의 혼용에 의한 고추의 세균성 점무늬병과 탄저병에 대한 방제 효과를 구명하고자 수행하였다. 세균성 점무늬병에 대한 방제 효과는 파인 오일만 단독 처리한 경우 발병엽률 59.6%와 방제 효과 28.9%로 나타났지만 파인 오일과 수산화동을 4:1로 혼용 처리하였을 때 발병엽률 20.0%와 방제효과 76.1%로 가장 효과적이었다. 탄저병에 대한 방제 효과는 파인 오일만 단독 처리한 경우 발병률 79.1%와 방제 효과 7.4%로 나타났지만 파인 오일과 수산화동을 4:1로 혼용 처리하였을 때 발병률 49.9%와 방제 효과 41.7%로 가장 효과적이었다. 이상의 결과는 고추의 세균성 점무늬병과 탄저병의 발병을 파인 오일과 수산화동을 4:1로 혼용 처리함으로서 친환경적으로 방제할 수 있음을 나타낸다.
