The Panel on Plant Health performed a pest risk assessment on Radopholus similis, the burrowing
nematode for the EU. The quantitative assessment focused on entry, establishment, spread and impact
on tropical and subtropical ornamental host plants, the main pathways for entry of R. similis into the
EU. Infested consignments are expected to enter the risk assessment area on ornamentals under all
scenarios. For citrus, which is a closed pathway for entry, outdoor establishment was assessed.
Establishment may only take place after successful transfer from ornamental plants to citrus
production systems. This event is called ‘shift’ in this assessment, to indicate that this is an unusual
transfer. It has been estimated that establishment of this nematode in the open field in the EU citrus
production areas under current temperatures is possible in most parts of the citrus production area in
the EU. Temperature conditions will prevent the nematode from establishing only in the northernmost
citrus areas and at higher altitudes in the south. Host plants for planting originating from infested
places of production (greenhouses) within the risk assessment area are considered the main pathway
for spread within the risk assessment area. Under current climatic conditions, the population of
R. similis is not expected to reach damaging population levels in the open field. In case of increased
temperatures due to global warming, the nematode population may reach damaging levels in very few
places outdoors. Currently, main impact is considered for ornamental greenhouse production in the risk
assessment area. Impact will be either caused by direct plant growth reductions or loss due to
phytosanitary measures applied on regulated plants. Despite the fact that R. similis is globally
considered as one of the most destructive plant parasitic nematodes, the impact in the risk assessment
area is considered low. [-]
