Abstract

Since the late 2000s, a serious Entomosporium leaf spot disease, caused by Entomosporium mespili, has been found frequently on leaves of Eriobotrya japonica and Photinia glabra at a nursery station in Goheung and Jeju, respectively. Studies were conducted to select fungicides that would effectively control Entomosporium leaf spot. Among the three fungicides tested, weekly foliar applications of propiconazole and chlorothalonil effectively reduced disease severity on E. japonica and P. glabra showing control value of 64.1% and 87.6%, respectively. Weekly treatments of thiopanate methyl were less effective. Propiconazole controlled the disease, but, it was phytotoxic to P. glabra.

2000년대 후반부터 고흥지역의 비파나무(Eriobotrya japonica)와 제주지역의 홍가시나무(Photinia glabra)에 Entomosporium mespili에 의한 극심한 점무늬병이 발생하기 시작하였다. 따라서 방제효과가 높은 살균제를 선발하기 위하여 이 연구를 수행하였다. 효과를 검정한 3개의 농약 중 비파나무 점무늬병에는 propiconazole 처리가 방제가 64.1%로 가장 높게 나타났고, 홍가시나무 점무늬병에는 chlorothalonil 처리가 방제가 87.6%로 가장 높게 나타났다. Thiopanate-methyl 처리는 방제가가 비교적 낮게 나타났고, propiconazole은 홍가시나무에 약해를 나타내었다.
