Recent Research on Mitigating the Effects of Leafroll and Red Blotch Viruses

Research Updates on Leafroll and Red Blotch Viruses in BC Vineyards

Two publications from Roberts et al. were released in 2025 pertaining to grapevine viruses. Specifically, these two articles assessed the effects of cluster thinning and viral load on Grapevine Leafroll Disease and Grapevine Red Blotch Virus in red cultivars in British Columbia.

This research was funded in part by Agriculture and Agri-Food Canada (AAFC), the British Columbia Wine Grape Council (BCWGC), and/or other industry and academic partners acknowledged in each article below.

"Role of Cluster Thinning and Viral Load on the Effects of Grapevine Leafroll Disease in Merlot and Cabernet Sauvignon in British Columbia, Canada"

"Mitigating the Effects of Grapevine Red Blotch Virus Using Crop Thinning and Investigating the Role of Viral Load on Vine Health and Fruit Composition in Cabernet Sauvignon in the Okanagan Valley, British Columbia"
