Hosts
Distribution
Unknown in stonefruit in California until detection in Sacramento and northern San Joaquin Valley in the spring of 2013.[4] As of 2017[update] it is still restricted to those two areas.[5] Also found in almond cultivation in Victoria, Australia.[6]
Detection
Palacio-Bielsa et al., 2011 provides a SYBR Green I-based assay.[7]: 90
Management
Copper[6] and mancozeb are recommended in California for almonds[5] and have served well elsewhere.[6] No pesticides are registered for almonds anywhere in Australia.[6]
Phage therapy has been heavily studied for X. pruni and some treatments have been very successful.[8][9] Civerolo & Keil performed several experiments in the 1970s with Xanthomonas pruni phage showing that peach and apricot were protected by external applications of solution.[10]
Resistance
Resistance to copper has occurred.[5] No copper resistance as of August 2017[update] in California.[5] Rotation or tank mixing is recommended to forestall resistance.[5]
