The Panel on Plant Health performed a pest categorisation of Xiphinema americanum sensu lato (Nematoda: Longidoridae) for the EU. Sixty‐one species in this group are recognised. They are polyphagous pests found in soil associated with a number of plant species. As a migratory ectoparasitic species, it punctures cells of plant roots. Nematodes were classified in four categories based on their distribution and ability to transmit viruses. Category I contains the seven virus vector species present outside the EU: X. americanum sensu stricto, X. bricolense, X. californicum, X. inaequale, X. intermedium, X. rivesi (non‐EU populations) and X. tarjanense. Category II contains the 28 species not present in the EU and not known to transmit any virus. Twenty‐six species are present in the EU and are not known to be virus vectors (category III). Category IV contains the species present in the EU, which is a virus vector (EU populations of X. rivesi). All nematodes known to be virus vectors occurring outside the EU (category I) satisfy all the criteria that are within the remit of EFSA to assess to be regarded as Union quarantine pests. This is mainly due to their association with non‐EU virus isolates. Categories II and III contain species that are not reported to transmit viruses or cause economic damage to crop plants. Although uncertainty concerning their ability to transmit viruses exists, those species do not satisfy all the criteria to be regarded as Union quarantine pests. Category IV contains the EU populations of X. rivesi. The species is a virus vector but current EU populations of X. rivesi have not been reported to be associated with any of the EU viruses or their non‐EU isolates under field conditions. Xiphinema rivesi (EU populations) is widespread in some Member States and does not satisfy all the criteria to be regarded as a Union quarantine. None of the species can be regarded as a regulated non‐quarantine pest.

“…However, not all species from this group of nematodes have been reported to transmit viruses. According to Taylor and Brown () the following species are considered as virus‐vectors: X. americanum sensu stricto , X. bricolense, X. californicum, X. intermedium, X. rivesi and X. tarjanense (Table ).

“…Nematode-transmitted viruses may persist for relatively long periods in their nematode hosts, and may also be acquired by the eelworm from weeds or root fragments that persist in the soil (Thomason and McKenry, 1975;Martelli, 1978). Control by fallow periods, or other cultural procedures is therefore difficult, so chemical treatment to kill the vector is probably the most effective means of control.…”

“…Strawberry runners tend to be propagated on hght mineral and organic soils so that planting and lifting are possible during the autumn and winter. Of the three soils at the sites used in these investigations, that at Site 2 would probably not be considered suitable for runner production because of its greater silt and clay content and its tendency to compact in wet weather, it has been shown that nematode control, using soil fumigant nematicides, is difficult in soils containing large amounts of organic matter due to sorption of the fumigant (Leistra, 1972;Thomason & McKenry, 1975;Hague, 1980). Peat soils in particular pose problems because of their porosity and water retaining capacity.…”

Fieid trials for the control of Xiphinema diversicaudatum and Longidorus elongatus in a peat soil, i. macrosoma in a fine sandy loam soil, and L. attenuatus and L. leptocephalus in a sandy soil were done using 1,3-dichloroprO'pene applied at various rates injected to either 15 cm oi split injected at either 15 and 30 cm or 15 and 45 cm. Good control of all the Qematode species was obtained at two of the three sites to at least 60 cm though very intensive sampling revealed smail residual populations following most treatments. The degree of control achieved at these two sites wouid probably reduce the risk tO' high-grade strawberry nursery stock grown on the sites from reservoirs of virus outside the site.
