First report of a foliar nematode Aphelenchoides fragariae (Aphelenchidae) on Stachys riederi var. japonica, a medicinal plant, in Korea

Abstract

Leaf blight symptoms and abnormal defoliation were found on Stachys riederi var. japonica, a medicinal plant, grown at Hongcheon, Gangwon province, Korea in 2007. A foliar nematode, Aphelenchoides ftagariae was isolated from infected leaf tissues. The symptoms observed on host plant were leaf blotching, discoloration and browning of tissues, tan-colored interveinal necrotic lesions and large dead patches of necrotic tissues. This is the first report of A. ftagariae occurring on S. riederi var. japonica.
