This organism can remain in soil for up to two decades, posing a threat to potato agriculture. The pest was identified by Helgi Jóhannesson, a horticultural consultant at the Agricultural Advisory Centre, during routine soil sampling last fall. Helgi said, "I found the nematode almost by chance, while looking for signs of a different pest."
Follow-up analyses revealed infections on three plots within the same farm. Samples from nine neighboring orchards were sent abroad for further evaluation. The nematode affects potato roots, impacting plant growth and production, although it is harmless to humans and animals. Helgi noted, "The infection spreads through contaminated seed potatoes and soil from machinery." Continuous cultivation in contaminated soil risks long-term usability loss.
Despite regulatory measures, imported ware potatoes and infected materials remain potential introduction sources. "Seed potatoes from an infected producer cannot be legally sold," Helgi noted. Comprehensive testing is necessary this fall to assess spread extent. Helgi commented, "If the pest is found in more areas, the consequences could be very serious."
Þórhildur Ísberg, Head of Plant Health at the Icelandic Food and Veterinary Authority (MAST), mentioned the ongoing investigation. "No decision has yet been made on containment or mitigation measures."
