‘Candidatus Liberibacter solanacearum’ does not occur in Canada
The NPPO of Canada officially declared that ‘Candidatus Liberibacter solanacearum’ (EPPO Alert List) has never been detected in Canada on tomato or potato. The record of ‘Ca. L. solanacearum’ in Alberta appearing in EPPO RS 2009/089 is considered erroneous. In addition, the psyllid vector (Bactericera cockerelli) is not established in Canada. It may be found in glasshouses, but outdoor populations only occur late in the season after migration from the USA and cannot overwinter under the Canadian climatic conditions.
