Abstract
In April 2008, cherry (Prunus yedoensis Matsumura) in Jeju exhibited severe disease of branches forming numerous twigs. Five isolates from diseased leaves were identified as Taphrina wiesneri on the basis of biological and genetic characteristics. Twenty one commercial fungicides were tested for control of the disease in vitro. Of the 21 fungicides, triazole compounds (difenoconazole, propiconazole and tebuconazole) showed relatively good antimicrobial activities. Results from the planta bioassays indicated that triazole compounds reduced the witches' broom disease showing control value $25.7{\sim}52.8%$ compared with the nontreated controls.
2008년 4월 제주도의 왕벚나무 빗자루병 이병옆으로부터 5개의 균을 분리하여 생리학적 방법과 유전학적 방법을 이용해 동정한 결과 Taphrina wiesneri로 동정되었다. 21개의 농약을 이용하여 실내 항균력을 검정한 결과 tebuconazole, difenoconazole, propiconazole과 같은 triazole계의 농약이 우수한 항균효과를 나타내었다. Triazole계의 농약을 처리한 야외 실험 결과 $25.7{\sim}52.8%$의 빗자루병 방제효과를 나타내었다.
