Diaporthe vaccinii is absent from the Netherlands
In the Netherlands, a single plant of Vaccinium corymbosum was found to be infected by a Diaporthe species in Horst (province of Limburg) in 2006. In 2007, the fungus was identified as Diaporthe vaccinii (EPPO A2 List). The infected plant was destroyed and the fungus was no longer detected on this site (EPPO RS 2009/130). In 2011, symptoms of a fungal disease were observed at another V. corymbosum fruit production facility in the same area, and similar symptoms were observed on V. myrtillus in a forest near Ede (province of Gelderland). In 2011, the causal agent of this disease was identified as D. vaccinii (EPPO RS 2013/104). The NPPO of the Netherlands recently informed the EPPO Secretariat that further studies have demonstrated that the fungus which was found and identified as D. vaccinii in 2011 was in fact Diaporthe eres. In 2013 and 2014, surveys were conducted at Vaccinium production sites and in public green areas to verify the possible presence of D. vaccinii in the Netherlands but all results were negative. The NPPO of the Netherlands considers that D. vaccinii is absent from its territory.
The pest status of Diaporthe vaccinii in the Netherlands is officially declared as: Absent, eradicated, confirmed by survey.
