Bolezen Syndrome Basses Richesses (SBR) sladkorne pese je povezana z bakterijo ‘Candidatus Arsenophonus phytopathogenicus’, ki je omejena na prevodno tkivo rastline in je ni mogoče gojiti v aksenični kulturi. Prenos poteka predvsem preko žuželčjih prenašalcev, zlasti škržatka Pentastiridius leporinus. V zadnjem desetletju je bolezen postala epidemiološko pomembna v več državah srednje in zahodne Evrope, zlasti na območjih intenzivne pridelave sladkorne pese. Poster povzema trenutno znanje o taksonomiji, biologiji in epidemiologiji povzročitelja, bolezenskih znamenjih, vlogi prenašalcev ter diagnostičnih metodah. Poseben poudarek je namenjen interpretaciji simptomov in pomenu laboratorijske potrditve ter epidemiološkemu okviru v državah, kjer bolezen še ni bila potrjena. Poster je bil predstavljen na 17. Slovenskem posvetovanju o varstvu rastlin (3.–4. 3. 2026).

This poster summarises current knowledge on Syndrome Basses Richesses (SBR) of sugar beet and its causative agent ‘Candidatus Arsenophonus phytopathogenicus’. The disease is transmitted by the planthopper Pentastiridius leporinus and has gained increasing attention in parts of Central and Western Europe. The poster highlights key aspects of pathogen biology, vector-driven epidemiology, host associations and diagnostic considerations. Particular attention is given to the interpretation of observations under conditions of high vector pressure and to the relevance of available information for plant health surveillance. The work forms part of activities supporting plant health monitoring and epidemiological interpretation in Slovenia. The poster was presented at the 17th Slovenian Conference on Plant Protection (3–4 March 2026).
