Plants of bellflower (Campanula medium) exhibiting symptoms of mosaic, leaf necrosis and flower ring spot were found in a commercial crop in a greenhouse in Atibaia, São Paulo State. Electron microscopy, serology and biological assays indicated the presence of Tomato spotted wilt virus (TSWV). This is the first report of this pathogen in bellflower plants in Brazil.
