In this episode of SpudChat, we talk to Dr. Mathuresh Singh of Agricultural Certification Services in Fredericton, New Brunswick.  Mathuresh and his team have been working on research into Potato Virus Y (PVY) over the last decade, providing a great deal of recommendations for seed growers on how to prevent the spread of PVY in their fields.  We chat about some of his past research findings and how that has been implemented on the farm in New Brunswick and beyond.
