Absence of Meloidogyne chitwoodi in England and Wales, UK
Since 1997, the NPPO of the United Kingdom has undertaken a survey in England and Wales to detect the species of Meloidogyne present in potatoes, making use of samples taken during the survey for potato ring rot and brown rot. ;511 samples have been examined from home-produced seed and ware, as well as seed and ware potatoes imported from other EU countries and ware potatoes from non-EU countries. In England and Wales, no infestations of M. chitwoodi (EPPO A2 quarantine pest) were found. The pest was found on imported ware potatoes from the Netherlands during 1996-1998, but no interceptions have been made since. A few samples of carrots, another host, have also been examined when found exhibiting symptoms of root-knot nematode infestation, but only M. hapla has been detected. The status of M. chitwoodi in England and Wales can be described as: Absent, confirmed by survey.
