PVY is the most common reason seed lots are rejected from organic certification, as pathogens more easily live in seed potatoes than in true seeds. Trials in this study, showed that neither border crops or inter crops had a consistent affect on PVY incidence. PVY incidence was most affected by the potato variety, with PVY resistant varieties like Red Norland performing better than PVY susceptible varieties such as Yukon Gold. Continued research is being funded.
