Proceedings of the 4th International Slovenian Congress on Vitiviniculture, Nova Gorica, Slovenia includs data on Slovenian nursery production.
During 2001-2010, 3,189 plant and 109 insect samples were collected in targeted surveys and analyzed for the presence of phytoplasmas by molecular methods. Phytoplasmas were found in 1,708 plant samples; in 19 cases mixed phytoplasma infection was identified. The majority of the samples were collected within systematic surveys conducted to determine the revalence of phytoplasmas in Slovenia. Among phytoplasmas, the most widespread phytoplasma on grapevine in Slovenia was the stolbur phytoplasma, (‘bois noir’). The same phytoplasma was also identified in Convolvulus arvensis and Lycopersicon esculentum. Since 2005, the ‘flavescence dorée’ phytoplasma, associated with serious disease of grapevine, has been reported in Slovenian vineyards. The same phytoplasma was also detected in Clematis vitalba. During the surveys, several known and putative vectors of phytoplasmas were identified.
