This factsheet is based on recent research done in Canada by Dr. Mathuresh Singh and his team in New Brunswick on PVY, which just concluded in March. This research has been very successful in identifying which production practices are most associated with reducing the spread of PVY. At the same time, PVY post-harvest test results in New Brunswick and Prince Edward Island have improved significantly in recent years, as these best practices are being more widely adopted. The factsheet was compiled by Ryan Barrett, Research & Agronomy Coordinator at the Prince Edward Island Potato Board, and published on the Peipotatoagronomy.com website.
