State Certification

What does certification mean?

Certification means that the plant material has a been subjected to a comprehensive process established, authorized and performed by a state or other governmental entity to minimize the occurrence of regulated pests and diseases in planting stock. State level certification focuses on testing for graft transmissible or systemic pathogens such as viruses.

Five states have grapevine certification programs – California, Missouri, New York, Oregon and Washington.

 

Common features of the programs:

  • Participation is voluntary
  • Registered blocks and foundations are visually inspected and/or tested for significant grape pathogens as defined by the state
  • Mechanism for tracking vines forwards and backwards
  • Isolation requirements from commercial plantings
  • Identity (true to typeness) requirements

 

State Certification Programs

The California Grapevine Registration & Certification Program handles the highest volume of certified grapevine material. Best estimates, based on nursery self reporting, are that approximately 50 million CDFA certified plants are sold annually. Regulations are described at:

Grapevine Registration and Certification Program from the California Dept. of Food and Agriculture

In New York, a certification program was reinstated in 2017.  Nursery stock is tested for grapevine fanleaf virus, tomato ringspot virus, tobacco ringspot virus, grapevine leafroll-associated viruses and grapevine red blotch virus. A presentation describing the program can be found at:

Clean Plants for the Future of the Eastern Wine and Grape Industry from Cornell University. 

In Missouri, a grape nursery stock virus disease certification program was started by the Missouri Department of Agriculture in 1989.  The regulations for this program can be found at:

Missouri Plant Law Rules from the Missouri Dept. of Agriculture (pages 7-8) 

In Washington and Oregon, the Grape Planting Stock Certification Programs are being revised to coordinate with similar programs in other western states, through a stakeholder working group made up of state regulators, university researchers and the wine and grape industry.  The process began in June 2016 and will result in harmonized rules (starting in 2019), making interstate shipping of grapevines easier while protecting the state from harmful pests and diseases of grapevines.

 A working group from the NCPN for Grapes met for the first time on May 2, 2012, in Davis, California, to begin discussion on harmonization of the existing standards and development of a set of regulations that reflect NCPN policy on clean plant certification and nursery regulation.

NCPN LogoThe National Clean Plant Network (NCPN) is a voluntary association of specialty crop networks that have joined to promote the use of pathogen-tested, healthy plant material for food crops in the United States. The NCPN operates under the auspices of three agencies within the United States Department of Agriculture - Animal and Plant Health Inspection Service (APHIS), Agricultural Research Service (ARS) and National Institute of Food and Agriculture (NIFA).
