Clavibacter michiganensis subsp. michiganensis found in the Netherlands on tomato plants for planting
In February 2007, Clavibacter michiganensis subsp. michiganensis (EPPO A2 List) was found on a tomato plant propagation company in the Netherlands. Only a very small number of tomato plants (including different cultivars) were affected at this propagation company. Affected plants had been grown from seeds originating from different countries (EU and non-EU countries). The possible source of this outbreak is still being investigated, but is most likely related to contaminated seeds. Forward-tracing investigations have revealed that a very small number of plants were infected at four companies producing tomato fruits for the final consumers, all located in the Netherlands. All plants concerned have been destroyed and prophylactic measures taken to prevent any further spread. Phytosanitary measures, including an intensified nation-wide specific surveillance of all propagation companies and further tracing to tomato-producing companies is being conducted to determine the possible occurrence of the pest, and ensure its eradication before the end of 2007.
The pest status of Clavibacter michiganensis subsp. michiganensis in the Netherlands is officially declared as follows: Transient, under eradication.
