Recombinant strains of Potato virus Y (PVY) were detected in western Washington for the first time in 2012 and 2013. Recombinants can arise naturally when two or more different virus strains co-infect a plant cell. The presence of recombinant strains of PVY in the region is troubling because these strains are sometimes able to infect potato plants without causing obvious foliar symptoms, thus, making visual recognition of infected plants unreliable and thereby confounding seed potato certification efforts. This publication describes research investigations that were designed to answer frequent questions about three PVY strains: O, NTN, and N-Wi, and provides suggestions on proactive measures that can be taken to mitigate both seed tuber-borne and current season PVY infections.
