First report of Xanthomonas arboricola pv. pruni in Serbia
In Serbia, Xanthomonas arboricola pv. pruni (EPPO A2 List) was first detected in 2019 on peach (Prunus persica) in a 13-year-old orchard located in Irig where the disease incidence was in the range of 10 to 20%. In 2020, the bacterium was also detected in apricot (Prunus armeniaca cvs. NS4, NS Rodna, and Roxana) in a 5-year-old orchard located in Bešenovo where the disease incidence was 30 to 50%. The identity of the bacterium was confirmed by biochemical, molecular and pathogenicity tests. The peach and apricot orchards are both located in the Fruška Gora region (Vojvodina). It is noted that in the diseased peach orchard, trees have been uprooted to eradicate the disease. Appropriate cultivation practice and surveys are being implemented to prevent further spread of the disease in Serbia.
The situation of Xanthomonas arboricola pv. pruni in Serbia can be described as: Present, not widely distributed.
