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, and Red Blotch 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 CGCN-RCCV Certification programs for the production of grapevines from Generations 1-4, become available.

VERSION: 2.0 - Amended October 12th, 2023

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, and Red Blotch 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.

As of September 2, 2019, Custom Propagation for Grape Growers/Wineries under the Interim Verification Program is available.

The Canadian Grapevine Certification Network (CGCN-RCCV) has opened up their Verification protocols to growers and/or wineries to test vines used for propagation for Grapevine Leafroll associated Virus 1 (GLaV1), GLaV3, and Red Blotch Virus (GRBV).  Plants that test negative for the three viruses will allow CGCN-RCCV 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. 

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. Removal of infected vines is optional unless the grower/winery wants to use the same plants for propagation for more than one year
  • CGCN-RCCV would need to be provided an audit trail that the grapevines where propagated and sold to the grape grower and/or winery
  • The nursery would need to remit the $0.10 vine levy to CGCN-RCCV on each vine sold
  • The grape grower and/or 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, 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 Ethan Churchill via email at ethan@cgcn-rccv.ca or phone 905-688-0990 ext 222 to sign up.
