First report of Impatiens necrotic spot tospovirus in Slovenia
In Slovenia, in July 2000, lower leaves of sweet pepper plants (Capsicum annuum cv. Blondi) grown under glasshouses showed necrotic rings and patterns. Electron microscopy revealed the presence of typical tospovirus particles. Serological tests (DAS-ELISA) confirmed the presence of Impatiens necrotic spot tospovirus (INSV - EPPO A2 quarantine pest) in symptomatic tissues. Further investigations on glasshouse crops showed that Tomato spotted wilt tospovirus (TSWV - EPPO A2 quarantine pest) occurred in pepper and tomato plants, and several ornamental species: chrysanthemums, Cyclamen, Spathiphyllum, and Zantedeschia (see EPPO RS 2001/084). INSV was also detected in chrysanthemums, and mixed infections were detected in Zantedeschia. In the vicinity of affected glasshouses, among tested weeds, TSWV was only detected in Artemisia vulgaris. This is the first report of INSV in Slovenia. The situation of INSV in Slovenia can be described as follows: Present: few reports, found in glasshouse vegetable and ornamental crops.
