Abstract

Fungicides of tebuconazole wp, iprodione wp and flusilazole wp were applied for the control of postharvest fruit rots of kiwifruit (Actinidia deliciosa) in the field in 2000 and 2001. More than 3 consecutive applications of these fungicides from the late June with 10-day-interval successfully controlled the diseases. It was found in the field trial in 2002 that 4 consecutive spays from mid of June with 10-day-interval was found to be the most effective application program for tebuconazole wp, iprodione wp and flusilazole wp, The results suggested that currently registered fungicides of benomyl wp and thiophanate-methyl wp can be substituted by tebuconazole wp, iprodione wp and flusilazole wp for the control of the diseases in Korea. Use of these fungicides can restrain emergence of fungicide resistant strains of postharvest fruit rot pathogens with benefit of reduced application of chemicals for food safety and environmental conservation.

2000년과 2001년 참다래 저장병 방제 실험 결과 터부코나졸 수화제, 이프로 수화제 및 후루실라졸 수화제의 살포적기는 7월 초였고 10일 간격 3회 이상 처리에서 방제 효과가 높았다. 세 가지 약제는 모두 6월 중순부터 10일 간격으로 4회 살포하는 것이 참다래 저장병에 대한 최대 방제효과를 얻을 수 있는 최적 살포 프로그램으로 2002년 포장실험 결과 확인되었다. 터부코나졸 수화제와 이프로 수화제 뿐만 아니라 후루실라졸 수화제는 우리나라에서 참다래 저장병 약제로 등록된 베노밀 수화제와 지오판 수화제를 대체할 수 있는 예방약제로 검증되었으므로 이 약제들을 활용하게 되면 약제의 다양화를 통하여 약제 저항성균의 출현을 예방할 수 있고 식품 안전과 환경보전을 위하여 약제 사용횟수도 줄일 수 있을 것으로 기대된다.
