Abstract

Xanthomonas arboricola pv. pruni (Xap), the causal agent of bacterial leaf spot disease of stone fruit, cause disease of stone fruits and almond worldwide. Xanthomonas arboricola pv. pruni (Xap) is regulated as quarantine pathogen in the European Union and the European and Mediterranean Plant Protection Organization (EPPO, A2 list). The bacterium can be latent and can be transmitted by plant material, and visual inspections are used for monitoring plants in orchards and nurseries. Monitoring was continuously conducted in period 2021-2023 in commercial orchards and registered nurseries on the territory of the Republic of Srpska. Leaves, twigs and branches of hosts (peach, nectarine, plum, apricot, cherry and sour cherry) were inspected and samples were taken for laboratory analysis. Detection and identification were done according to EPPO diagnostic protocols PM 7/64(1) and PM 7/100 (1), with slight modifications. As a reference material it was used freeze dried bacteria CFBP 2535 (producer CIRM, France). Out of 321 analyzed samples, 21 samples  (plum, cherry, peach and apricot) confirmed as positive. Further studies on Xanthomonas arboricola pvs. are planned to be conducted in the following period.
