The propagation and shipment of grapevines is considered to be a high-risk pathway for the movement of plant pests. Viruses and virus-like organisms are very common in the production of grapevines.
While some viruses are known to have a minor effect on infected grapevines, other viruses can cause very serious diseases and can lead to major crop losses (e.g. Grapevine leafroll disease). Grapevines that have been infected by viruses, and most other virus-like organisms, cannot currently be cured.
The only way to remove a virus from a vineyard or a block of nursery grapevines is by destroying the infected host plants and by replanting clean grapevines free of viruses. A virus certification program, like the one developed by CGCN, is based on the propagation of grapevines using nuclear material (called Generation 1 (G1)) under Option 1 Protocols, or through the use of High-Throughput Sequencing technology to test already existing vineyard blocks under Option 2 Protocols.
The CGCN-RCCV Certification Program uses a systems approach in order to produce virus tested grapevines. Various independent components such as virus-testing, field inspection, isolation distances, and vector control, all work together to minimize the presence and the spread of viruses
CGCN has launched the long-term Certification Program as of September 16th, 2019, and amended the program as of March 8th, 2021. We are open to applications from nurseries at any level(s). Please contact us if there are any questions.
CGCN-RCCV Certified Plus Program - formerly Option 1
Version 2.0
This protocol involves propagation of grapevines using nuclear material (Generation 1). The resulting product produced under these program standards is called "CGCN-RCCV Certified Plus."
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 in order to produce virus tested grapevines.

CGCN-RCCV Certified Program - formerly Option 2
VERSION 2.0
This protocol involves propagation of grapevines using already existing vineyard blocks that have undergone and passed rigorous testing procedures via High-Throughput Sequencing technology (Generation 3). The resulting product produced under these program standards is called "CGCN-RCCV Certified."
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 in order to produce virus tested grapevines.
