Xanthomonas pruni (syn. Xanthomonas campestris pv. pruni, syn. Xanthomonas arboricola pv. pruni) is a bacterial disease of almost all Prunus.

Hosts

Almost all Prunus spp.[1]

Distribution

Unknown in stonefruit in California until detection in Sacramento and northern San Joaquin Valley in the spring of 2013.[1] (As of 2017) it is still restricted to those two areas.[2] Also found in almond cultivation in Victoria, Australia.[3]

Detection

Palacio-Bielsa et al., 2011 provides a SYBR Green I-based assay.[4](p90)

Management

Copper[3] and mancozeb are recommended in California for almonds[2] and have served well elsewhere.[3] No pesticides are registered for almonds anywhere in Australia.[3]

Phage therapy has been heavily studied for X. pruni and some treatments have been very successful.[5][6] Civerolo & Keil performed several experiments in the 1970s with Xanthomonas pruni phage showing that peach and apricot were protected by external applications of solution.[7]

Resistance

Resistance to copper has occurred.[2] No copper resistance (As of August 2017) in California.[2] Rotation or tank mixing is recommended to forestall resistance.[2]
