Potato Leafroll Virus (PLRV) can significantly affect the yield and quality of seed and ware potatoes. PLRV levels remained very low across GB for many years, but recent seasons have seen a resurgence both domestically and across other major European potato-producing countries. The causes of this change are not yet fully understood, and the information that does exist is scattered across scientific studies and day-to-day industry experience, making it hard to view the full picture. In this project we will gather expert opinions from the potato industry alongside existing scientific and technical knowledge on PLRV. These will be synthesised to produce a comprehensive review of the factors that influence PLRV risk in GB. This information will support industry decision-making by improving understanding of how PLRV risk is shaped under current and emerging production conditions.
