G. rostochiensis and G. pallida are quarantine pests. • In Norway all pathotypes of G. pallida and most pathotypes of G. rostochiensis except pathotype Ro1 are considered virulent. • Non-virulent G. rostochiensis is managed by crop rotation using non-host crops; alternating susceptible and resistant cultivars. • Infestations by G. pallida or virulent G. rostochiensis results in 40-years ban on growing potato
Background of potato cyst nematode (PCN) in Norway • In 1955 the potato cyst nematode was recorded for the first time in Agder. This detection produced the initial legislation of PCN control, and was implemented based on the statutory regulation of 1916. • Since 1956 PCN was given quarantine status in infested agricultural land and home gardens. • The 1956 PCN legislation stipulated measures in event of finding infestation. • The growing of ware potatoes were restricted to at least 4 year rotation, and prohibited the unauthorised movement of infested soil, by any means, to prevented spread to adjacent areas. • This detection resulted in extensive surveys.
