First report of Globodera pallida in USA


In April 2006, during routine surveillance carried out in potato fields in Idaho, the presence of Globodera pallida (EPPO A2 list) was detected for the first time in USA. Two cysts were found in a soil sample. In June 2006, the source of the infestation was traced back to one field in Bingham county, Idaho. This field has been producing potatoes for consumption and processing, but not seed potatoes. In July 2006, a soil sample from another field within the same farm also tested positive for G. pallida. Phytosanitary measures were immediately taken to prevent any further spread of the nematode. So far, the infestation appears to be limited to these two fields, but surveys are continuing.
The situation of Globodera pallida in USA can be described as follows: Present, first found in 2006 in 2 potato fields in Idaho, under official control.
