A pair of closely related microscopic roundworm species (Globodera rostochiensis and Globodera pallida) that form cysts on potato roots and can persist in soil for a decade or more even without a host present. Infested fields are subject to strict quarantine and rotation requirements in most potato producing countries, since established populations are extremely difficult to eliminate and can force land out of potato production for years.

Wikimedia FoundationOpening definition paragraph
Potato root nematodes or potato cyst nematodes (PCN) are 1-mm long roundworms belonging to the genus Globodera, which comprises around 12 species. They live on the roots of plants of the family Solanaceae, such as potatoes and tomatoes. PCN cause growth retardation and, at very high population densities, damage to the roots and early senescence of plants. The nematode is not indigenous to Europe but originates from the Andes.
