초록

네 종의 관상수목에서 흰가루병이 발생하였는데, 이들은 지금까지 한국에서 보고되지 않았으므로 발병양상을 기록하고 병원균을 동정하였다. 노린재나무 흰가루병은 그늘에서 자란 잎에서만 약하게 발생하였으므로 그리 문제되지는 않을 것으로 생각되는데, 병원균은 Microsphaera nomurae U. Braun으로 동정되었다. 꽃산딸나무 흰가루병은 그리 심하지 않았으나 묘포에서의 대발생이 우려되었는데, 병원균은 Microsphaera pulchra Cooke & Peck으로 동정되었다. 야광나무 흰가루병은 묘포에서 어린잎과 어린줄기에 주로 발생하였는데, 병원균은 Podosphaera leucotricha (Ellis & Everh.) Salmon으로 동정되었다. 왕느릅나무 흰가루병은 주로 가을철에 발생하였으며 2차 생장한 어린 가지에서 특히 심하였는데, 병원균은 Uncinula kenjiana Homma로 동정되었다.

Powdery mildew diseases previously unrecorded in Korea were noticed on four species of ornamental trees. Field observations on each disease were described and the causal fungi were identified. Powdery mildew of Symplocos chinensis for. pilosa was found to occur mildly, especially on plants growing in shade. The causal fungus was identified as Microsphaera nomurae U. Braun. Cornus florida was found to be infected with Microsphaera pulchra Cooke & Peck and supposed to be epidemic in nursery. Powdery mildew of Malus baccata occurred on young leaves and herbaceous stems in nursery. The causal fungus was classified as Podosphaera leucotricha (Ellis & Everh.) Salmon. Powdery mildew of Ulmus macrocarpa was found to occur in autumn and severe on young shoots. Uncinula kenjiana Homma was identified as the causal fungus.
