Sažetak
Grapevine yellows (GY) diseases cause severe economic damage by reducing yields and quality of grape and ultimately lead to overall decline of plants. One of most important GY agents, Flavescence doree (FD) phytoplasma, is a quarantine organism in the Europe due to its Cicadelidae vector Scaphoideus titanus Ball. which disseminates FD in epidemiological manner. GY diseases have been continuously monitored during the last ten years throughout the official annual survey programme and for the first time in the 2009. the presence of FD phytoplasma was confirmed at several locations. From the first fmding the number of FD infected samples as well as the number of affected locations has increased. With the aim to elucidate FD phytoplasma epidemiology in Croatia and establish source and ways of dissemination, two locations - Brckovstina (Kri2evci) and Jagnjic Dol (Samobor), representing FD phytoplasma foci have been chosen. FD phytoplasma presence was confirmed in 8 out of 10 grapevines and in 12 out of 21 S. titanus samples. Molecular analyses clearly showed a presence of distinct isolate at each of the two locations; the isolate FD-1 at Brckovstina and FD-3 at Jagnjic Dol.
