First occurrence of grapevine flavescence doree in Slovenia: how to proceed?
Grapevine flavescence dorée phytoplasma (FD) was found in Slovenia (Ankaran, Southwest Slovenia) for the first time in 2005. In 2006, two further foci of FD were discovered inside the five-kilometre buffer zone of the first focus. Until now infected vine stocks were only found among the vine cultivars 'Pinot gris', 'Chardonnay' and Malvasia. Inside the infected area phytosanitary measures have been carried out. Elimination of symptomatic vine stocks and obligatory treatments with insecticides against the vector Scaphoideus titanus Ball has been approved. Obligatory insecticide treatments are also being required in all vine nurseries and in the vine mother stands, if the presence of the pest has been established. The three years survey of the vector has shown its presence in both continental winegrowing regions as well.
