Interim Verification Program

CGCN Resources

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, become 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 this 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. 

As of September 24th, 2019, Custom Propagation for Grape Growers/Wineries under the Interim Verification Program is available:

The Canadian Grapevine Certification Network (CGCN-RCCV) has received funding from the Canadian Agricultural Partnership (CAP) program to test vines used for propagation for Grapevine Leafroll associated Virus 1 (GLaV1), GLaV3, Red Blotch Virus (GRBV) and Pinot Gris Virus (GPGV). The funding will reduce the cost of testing by approximately fifty percent. Plants that test negative for the four viruses will allow CGCN to verify the scion/rootstock wood used from these plants in plant propagation have passed the interim grapevine testing standard. We are opening the program to Canadian grape growers and/or wineries who would be interested in partnering with a nursery for custom propagation of grapevines.

Custom Propagation in this instance is defined as a grape grower and/or winery enlisting the services of a nursery to propagate a specific number of grapevines from a specific section of their own vineyard (propagation block) and then purchasing the resulting grapevines for their own uses. 

As with other grapevines produced under the program, only the portion of the vine being tested can be verified by CGCN-RCCV. If the scion wood/rootstock comes from an alternate source, not tested by the CGCN-RCCV no claim of CGCN-RCCV verification can be made on that portion of the grapevine, but if the rootstock/scion wood comes from another certification program, that program’s claim can be made on the specific portion of the plant.  

 How this works:
-          The nursery and grape grower and/or winery both need to have a signed contract with CGCN-RCCV
-          There would need to be a proven relationship for propagation between the grape grower/winery and nursery
-          The grape grower/winery, agrees to pay for the testing, collection and mapping of the propagation block as well as travel. Testing can be done on leaf or cane samples
-          The grape grower/winery will follow the same Code of Practice as the nurseries including removing infected vines. 
-          CGCN-RCCV would need to be provided an audit trail that the grapevines were propagated and sold to the grape grower/winery 
-          The nursery would need to remit the $0.25 vine levy to CGCN on each vine sold. 
-          The grape grower/winery would not have to continue testing at the audit level if they choose to not take budwood the following year. If they do choose to take budwood again, audit testing is required.
Custom Propagation for Grape Growers/Wineries under the Interim Verification Program is now available on a limited, first-come-first served basis. Please contact Project Manager, Jill Page via email jwindeatt@cgcn-rccv.ca or phone 905-688-0990 ext 222 to sign up. 

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.
