Further details about the presence of Chrysanthemum stem necrosis tospovirus
The NPPO of Slovenia recently informed the EPPO Secretariat about the current situation of Chrysanthemum stem necrosis tospovirus (CSNV – EPPO A1 list). In 2001, CSNV was detected in 23 samples of Chrysanthemum and in 2002 in 1 sample of Gerbera (see EPPO RS 2003/041). The identity of CSNV was confirmed by ELISA, different test plants and PCR. Infected plants were destroyed by incineration. In 2003, CSNV was not detected.
