“…The bacteria overwinter in cankers, dead and symptomless buds and systemically infected branches (Vigouroux, 1970;Kennelly et al, 2007). In spring, bacteria that infected leaf scars can become active resulting in blast of buds and die-back of shoots and branches (Young, 1987a). During this period, the bacteria can be spread via splash dispersal and wind-driven rain from leaves to blossoms, resulting in blossom blast.…”

“…Planting material should be obtained from areas in which the disease does not occur. The use of less susceptible cultivars may restrict dissemination (Young, 1987a;EPPO, 1997) but the susceptibility to P. s. pv. persicae is no more taken into consideration for the choice of varieties to be planted because this trait is not included in the current breeding programmes.…”

“…Waterlogging of soils, which can impair plant defences as result of oxygen depletion, should be avoided, e.g. by deep ploughing or settling of shallow soils (Young, 1987a). Irrigation late in the growing season, when frost can occur, should be avoided (Young, 1987a).…”

The European Commission requested the EFSA Panel on Plant Health to perform the pest categorisation for Pseudomonas syringae pv. persicae (P. s. pv. persicae). The agent is responsible for bacterial die-back in peach, nectarine, Japanese plum and, possibly, myrobalan plum. The disease is caused by a genetic clade within genomic species 3 of P. syringae, but there is only limited knowledge of the diversity of the causative agent. The host plants are cultivated throughout Europe, although it is only in southern European countries that the production of peaches and/or nectarines is of economic importance, and the cultivation of Japanese plums is restricted to some parts of southern Europe. Outbreaks are rare and currently the disease occurs only sporadically in Portugal, France and Germany. P. s. pv. persicae causes symptoms on the bark, shoots, leaves and fruit. Detection is based on symptomatology and isolation; no DNA amplification (polymerase chain reaction) protocols are available. The pathogen can be identified on the basis of disease symptoms, including shoot dieback and leaf spots, and on the basis of distinct biochemical and genetic properties. No effective management strategies are available, although disease incidence and severity can be somewhat reduced by disinfection of tools, machines and materials, the use of planting material from disease-free areas, and the avoidance of conditions favouring disease expression. Initial infections may be due to the use of (latently) infected plant material, but infections may also occur from the environment. No effective biological or chemical control agents are registered for bacterial die-back in Europe. The outbreaks, although they occur sporadically, are usually severe and can result in the loss of entire orchards. © European Food Safety Authority, 2014 KEY WORDSPseudomonas syringae pv. persicae, bacterial die-back of peach, bacterial decline of nectarine and peach, bacterial canker of peach, quarantine pest, regulated non-quarantine pest

Bacterial canker of cherry is a major constraint to stone fruit production worldwide, including New Zealand. Six pathovars of the bacterium Pseudomonas syringae are known to cause bacterial canker on Prunus species. From those six pathovars, P. s. pv. syringae (Pss), P. s. pv. morsprunorum race 1 (Psm1) and P. s. pv. persicae have been reported as pathogens of Prunus species in New Zealand, and Pss and Psm1 on sweet cherry (Pr. avium). On sweet cherry, extensive development of cankers and gummosis is usually observed, particularly during late winter and spring, with the progressive decline of trees resulting from the death of branches or death of the plant. In young orchards in New Zealand, losses of 20–50%, and sometimes the removal of entire cherry blocks have been observed. This review reports on the current knowledge of P. syringae pathovars causing bacterial canker of Prunus species, with specific focus on sweet cherry in New Zealand, and covers their identification, the infection process, virulence associated factors, epidemiology, symptoms, and management strategies.
