Eradication of Chrysanthemum stem necrosis virus from Belgium
In September 2012, the presence of Chrysanthemum stem necrosis virus (Tospovirus, CSNV – EPPO A1 List) had been detected at 1 location on glasshouse chrysanthemums (Dendranthema spp.) in the Western part of Belgium (see EPPO RS 2013/028). Eradication measures (destruction of all affected plants) were applied and follow up surveys were carried out by the Federal Agency for the Safety of the Food chain (FASFC). These official surveys for CSNV were carried out in all Belgian breeding companies of chrysanthemums (from January until the end of March) in 2013 and 2014. All collected samples (108 in 2013 and 118 in 2014) tested negative for CSNV. The NPPO now considers that CNSV has been eradicated from Belgium. Nevertheless, this virus will continue to be part of the yearly survey programme of the FASFC.
The pest status of Chrysanthemum stem necrosis virus in Belgium is officially declared as: Absent, pest eradicated, confirmed by survey.
