Our Grapevine Virus Testing Service
Grapevines are susceptible to many virus and virus-like agents that can negatively impact the health and quality of grapevine and its products. Detection is a first step in the management of grapevine virus diseases.
At Brock University’s Cool Climate Oenology and Viticulture Institute, we offer highly sensitive and accurate molecular virus diagnostics through CCOVI’s Virus Testing Services to help manage the health status of grapevines.
Our ongoing research will assist in the management of grapevine virus diseases through dissemination of science-based knowledge, innovation and collaborations to serve the Canadian grape and wine industry.
Our virus testing services offer competitive pricing packages for a wide range of grapevine-infecting, non-regulated viruses including but not limited to:
- Grapevine Red Blotch Virus
- Grapevine leafroll-associated virus 3
- Grapevine Pinot Gris Virus
- Grapevine Fan Leaf Virus
- Grapevine leafroll-associated virus 1
- Grapevine leafroll-associated virus 2
- Grapevine leafroll-associated virus 4

Navigate to Brock University’s northeast entrance at John Macdonell Street off Glenridge Avenue. Turn west into campus. There will be a roundabout, take the second exit. Drive forward toward the buildings. Inniskillin Hall is straight ahead, with purple-red accents on the windows, and the new VPMI is attached to its right.
There are two “Reserved CCOVI” parking spots across from the building available for quick parking. Put on your four-way flashing lights, walk down a few stairs, then enter the new building through the double glass doors. Walk through the white foyer to the Inniskillin Hall foyer, where a sign will direct you to turn left toward a hallway. Walk toward the purple doors, follow the hallway around a right turn, and you’ll find IH215 on the right. There are more forms and information at the table outside the lab if the door is closed.
