Summary of the Express Pest Risk Analysis for Xanthomonas arboricola pv. pruni (Smith) Vauterin, Hoste, Kersters & Swings

PRA area: Poland

Decribed of endangered area: stone fruits crops – most of peach, nectarine, apricot, cherries orchads are in Wielkopolskie, Mazowieckie, Świetokrzyskie and Podkarpackie provinces (GUS 2012)

Main conclusions:

X. arboricola pv. pruni is bacteria which infects Japanese plum (Prunus salicina), peach (Prunus persica) i apricot (Prunus armeniaca). All of those plants are rarely cultivated in Poland. However, other host species ( Prunus avium, Prunus cera sus, Prunus domestica) are cultivated in large areas in Poland. Moreover some host species are growing in wild. Given the above, the likelihood of pest establishment is PRA area is moderate.

Rating of the likelihood of spread: low (Because of systematic controls of propagation material and lack of vectors)

In accordance with Regulation of the Ministry of agriculture and rural development of 21.02.2008 relating to preventing the introduction and spread of quarantine pests – the need to import only X. arboricola pv. Pruni-free plants for planting (not seeds) belong to Prunus genus.

Rating of the likelihood of entry: low (infested fruits may be imported from area of pest occurence)

Rating of the likelihood of impact without phytosanitary measures: low (except area of host plants crops).

Phytosanitary measures are basic methods in case of pathogen occurence in propagation material or in seedlings.
