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 50 per cent and will be available for three years. Plants that test negative for the four viruses listed above will allow CGCN to verify the scion/rootstock wood used from these dormant plants in plant propagation have passed the interim grapevine testing standard. Resulting plants will be available from spring 2021 from participating nurseries. Some greenhouse-propagated plants may be available for planting early summer of next year.
“Because program rules do not allow for unspent funding to be re-allocated to subsequent years, it is critical that we take full advantage of the current year allocation,” says Hans Buchler, chair, CGCN. “We urge all grape growers who are looking to plant clean material in the coming years to contact any of the participating nurseries with their requirements for varietals and clones so that the nurseries can adequately plan their production for the coming years. Collection of samples and testing of samples is time-consuming and must start now for the program to be successful this year. Please contact any of the nurseries listed below with your grapevine requirements for the near future.
