First report of Globodera pallida in Morocco

During surveys for potato cyst nematodes in 2019-2020, 1500 soil samples were collected just before the harvest of potato (Solanum tuberosum) in different potato-producing regions of Morocco: central western (Casablanca-Rabat), eastern (Nador-Berkane), northern (Larache-Tangier), central (middle Atlas), south-eastern (Midelt-Errachidia), and south-western (Agadir-Taroudant). Cysts were extracted and identified by morphological and molecular methods. The presence of Globodera pallida (EPPO A2 List) was confirmed in 3 regions: Berkane (Eastern Morocco), Gharb and Doukkala (Western Morocco).

The situation of Globodera pallida in Morocco can be described as: Present, restricted distribution (Berkane, Gharb and Doukkala).
