Situation of Globodera rostochiensis and G. pallida in Canada
In Canada, based on decades of soil surveys, the presence of Globodera rostochiensis (EPPO A2 List) has only been detected in Newfoundland and in a small area (Saanich) of Vancouver Island (British Columbia). Globodera pallida (EPPO A2 List) is only present in a small area of Newfoundland. Both nematode species are quarantine pests in Canada and are subjected to strict official control measures. In August 2006, G. rostochiensis was detected in Quebec and surveys were implemented to delimit the extent of the infestation. Approximately 50 000 soil samples were collected from Quebec and other areas of Canada. As a result, few infestations were detected in the municipality of Saint-Amable, as well as in portions of the municipalities of Sainte-Julie, Saint-Marc-sur-Richelieu and Saint-Mathieu-de-Beloeil. A total area of 4 750 ha, including 2 000 ha of agricultural land is being regulated in Quebec.
