First report of impatiens necrotic spot tospovirus on ferns


In May 1991, in a greenhouse in Spain, fern plants (Asplenium nidus-avis) showed symptoms of ring spot and numerous necrotic lesions on the leaves. No fungal or bacterial pathogen could be isolated. However, by using DAS-ELISA and polyclonal antisera, it was possible to detect the presence of impatiens necrotic spot tospovirus (potential EPPO A2 quarantine pest). The authors believed that this is the first report of the virus from a pteridophyte.
