Abstract
Colletotrichum gloeosporioides에 의해 발생하는 딸기 탄저병에 대한 여러 살균제의 방제효과를 in vitro, 비닐하우스와 노지 육묘포장에서 검정하였다. Benomyl의 $EC_{50}$ 값은 균주 간에 저항성과 감수성 그룹으로 확연히 구별되었다. Iminoctadine tris는 mancozeb나 propineb과 같은 보호살균제보다 낮은 EC50값을 보였으며 mancozeb, propineb, azoxystrobin의 효과는 균주에 따라 다양한 결과를 보였다. 비닐하우스에서, 9종의 살균제를 병원균 접종 전과 후 딸기 '설향' 품종에 처리하였을 때 모든 약제는 무처리에 비해 방제효과가 좋았다. Propineb, mancozeb, azoxystrobin은 병원균 감염 전 처리 시 방제효과가 우수했던 반면 metconazole과 prochloraz-Mn와 같은 ergosterol biosynthesis inhibiting 살균제들은 낮은 탄저병 이병율을 보였다. 2009년과 2010년 노지 육묘포장에서 감소된 살균제 처리 프로그램에 따른 탄저병 방제는 captan 처리 프로그램과 비슷한 방제효과를 보였다. 따라서 prochloraz-Mn 등과 같은 탄저병에 효과적인 살균제를 기반으로 작성된 처리 프로그램은 딸기 농가에 유용하게 사용될 수 있고 탄저병 방제를 위한 더 많은 선택을 제공할 것이다. The effect of various fungicides on anthracnose of strawberry, caused by Colletotrichum gloeosporioides, was determined in vitro, and in greenhouse and field trials. The $EC_{50}$ values of benomyl were clearly different between two sensitive and resistant groups of isolates. Iminoctadine tris had lower $EC_{50}$ values than mancozeb and propineb as protective fungicides and the response of mancozeb, propineb and azoxystrobin was variable depending on the isolate. In the greenhouse, pre- and post- inoculation fungicide applications significantly reduced disease compared to the non-treated control. Propineb, mancozeb and azoxystrobin were effective in controlling the disease when applied prior to inoculation. Metconazole and prochloraz-Mn treatments as ergosterol biosynthesis-inhibiting fungicides had the lowest incidence of anthracnose. In the nursery field trials in 2009 and 2010, the reduced fungicide spray program provided similar levels of disease control compared to the calendar-based applications with captan. A reduced spray program based on efficacious fungicides such as prochloraz-Mn will be useful for strawberry growers and provide more options for controlling anthracnose in Korea.
