Abstract

In September 2011, black leaf mold caused by Pseudocercospora fuligena occurred on tomato plants growing in protected cultivation conditions in Boryong and Buyeo, Chungnam Province, Korea. Symptoms of the disease initially appeared as foliar chlorotic spots on upper leaf surfaces, turned light brown and then black on lower leaf surfaces as the fungus sporulates profusely. The causal fungus was isolated from the diseased plants and identified as P. fuligena based on morphological characteristics. Pathogenicity of the fungus was proved by artificial inoculation in the green house. This is the first report of the occurrence of black leaf mold of tomato caused by P. fuligena in Korea.

2011년 9월, 충남 보령시와 부여군의 시설재배단지에서 재배중인 토마토의 잎에 Pseudocercospora fuligena에 의한 검은잎곰팡이병이 발생하였다. 이 병의 병징은 초기에는 잎에 연한 노란색의 불규칙한 점무늬가 발생하며, 점차 연한 갈색으로 변하고 잎 뒷면의 병반부위에 병원균의 분생포자를 다량으로 형성하면서 검은색의 그을음 병징을 나타내었다. 병든 토마토 식물체로부터 원인균을 분리하였고 현미경 검경을 통하여 형태적 특징을 분석한 결과 P. fuligena로 동정되었다. 온실조건에서 인공접종을 통하여 이 균의 병원성을 증명하였다. P. fuligena에 의한 토마토 검은잎곰팡이병의 발생은 우리나라에서 최초의 보고이다.
