Summary

This report concerns the first official findings of TYLCV recorded in the Netherlands. TYLCV is listed as a harmful organism for the European Community which is known to occur in the Community and specifically regulated on tomato plants intended for planting, other than seeds (see Annex IIAII of Council Directive 2000/29/EC as amended). The outbreak was first suspected at one company in the beginning of September and officially identified at the end of September. Currently, findings concern a small number of companies and a very low number of infected plants (varying between three and approximately twenty plants per company). Thus far, no findings have been recorded at companies producing plantlets intended for sale to professional growers. The source of the outbreak has not been identified. A nationwide specific surveillance has been planned to determine the extent of the outbreak. Measures at companies are ongoing in the Netherlands, whereby affected plants are removed and destroyed. Furthermore, relevant companies have to apply insecticide treatments aimed at eradicating populations of B. tabaci. A hygienic protocol is required at affected companies for preventing further spread. Trace-back has been initiated for determining the possible source of the outbreak. Trace-forward is not relevant, because the plants are not traded by the companies concerned. Since specific surveillance of companies growing plants for planting (for fruit production, seed production, or propagation purposes) has been carried out during previous years, it is presumed that this is the first outbreak of TYLCV in the Netherlands.

Danger

This report concerns the first official findings of TYLCV recorded in the Netherlands. The immediate danger is estimated to be low, since the findings concern a small number of companies and a very low number of infected plants (varying between three and approximately twenty plants per company). Thus far, no findings have been recorded at companies producing plantlets intended for sale to professional growers. The source of the outbreak has not been identified.
