Notes: Grapevine Roditis leaf discoloration-associated virus (GRLDaV) is a member of the species Badnavirus decoloratiovitis in the genus Badnavirus that was recently identified in grapevine using high throughput sequencing. In this study, a largescalesurvey was conducted to monitor the prevalence of the virus in major viticultural areas of Greece. In transmission tests conducted using Planococcus ficus (Signoret) and 48 h acquisition access period (AAP) and inoculation access period (IAP), the virus was transmitted with an efficiency of 14.3% (3/21 grapevines). Finally, electron microscopy revealed the bacilliform morphology of GRLDaV virions, thus further confirming its episomal infection.
