Interim Verification Program

Interim Verification Program 


CGCN has developed an the Interim Verification Program to aid nurseries in producing saleable grapevines with a low risk of virus infection of Leafroll 1, Leafroll 3, Red Blotch and Pinot Gris Virus through virus testing of the existing propagative blocks and removal of infected plants and associated plants with high risk of infection. This is meant to be a temporary measure, until quantities of plants produced under the Long-Term CGCN-RCCV Certification Standard for the production of grapevines from Generations 1-4, becomes available. Nurseries will be able to make the claim "propagation material tested and found clean of Leafroll1, Leafroll 3, RedBlotch, and Pinot Gris Virus" on resulting material from this program.   

Look for the below badge at your favourite Canadian Nursery to see if they are a Participant in CGCN's Interim Verification Program!

Current Participants in the Interim Program include:

*Please check back regularly, as CGCN will be posting vines that are available under the program on our website as testing is completed. As of August, 2019 testing is underway, and no nursery has yet been given verification under the program. 

Interim Verification Standard 

VERSION NUMBER: 1.1

SUBJECT: This program contains the requirements for the production of Vitis spp. nursery stock (grapevines) for domestic use, including ornamental species. This program uses a systems approach to aid nurseries in producing saleable grapevines with a low risk of virus infection of Leafroll1, Leafroll 3, Red Blotch and Pinot Gris Virus through virus testing of the propagative blocks and removal of infected plants and associated plants with high risk of infection in order to produce tested grapevines for specific viruses. Nurseries will be able to make the claim "propagation material tested and found clean of Leafroll1, Leafroll 3, RedBlotch, and Pinot Gris Virus" on resulting material.

From Our Team

  • Having a clean plant program in Canada will allow growers to replant vineyards with healthy domestically produced vines to maintain the long-term viability of their vineyards.
