Nursery Stock Registration & Certification Programs
In order to provide extra insurance to growers that specific types of nursery stock are meeting a higher standard of pest and disease cleanliness, CDFA's Nursery Services Program coordinates Registration and/or Certification programs for seven different types of nursery stock. These Registration and Certification Programs are funded by fees paid by program participants.
Avocado Registration & Certification
CDFA has two separate voluntary programs for Avocado Nursery Stock. The Avocado Certification Program provides for treatment and maintanance to protect avocado nursery stock from Avocado Root Rot caused by Phytophthora cinnamomi. The Avocado Registration Program provides for the testing of avocado budwood source trees for Avocado Sunblotch Viroid.
Citrus Nursery Stock Pest Cleanliness Program
The Citrus Nursery Stock Pest Cleanliness Program is a mandatory program for citrus nursery sources. All source trees for citrus propagative materials must meet the testing and maintenance requirements for this program.
Any citrus nursery stock production that does not meet the requirements of this Program may be subject to enforcement action by CDFA or the County Agricultural Commissioner.
Fruit & Nut Tree Registration & Certification
Deciduous fruit and nut trees may be registered for the purpose of providing rootstock and scion sources for the propagation of certified nursery stock when inspected and tested for regulated diseases, such as Prune Dwarf Virus and Prunus Necrotic Ringspot Virus.
Pome fruit trees may be registered for the purpose of providing rootstock and scion sources for the propagation of certified nursery stock when inspected and tested for specific virus diseases and other pests.
Grapevine Registration & Certification
The Grapevine Registration & Certification Program provides for the testing of source vines for significant grape pathogens, such as Grapevine Fanleaf Virus and Grapevine Leafroll viruses. Registered sources and certified nursery stock are then inspected by CDFA staff and maintained by the participant in a manner to protect them from exposure to regulated diseases.
Seed Garlic Certification
The California Certified Seed Garlic Program is a voluntary multi-level certification system initiated in 1960. Foundation stock is derived from tissue cultured garlic and may enter the program after one year of inspection. Registered stock is derived from Foundation stock, and Certified stock may be produced from either of the upper levels. Foundation and Registered stock may recycle in the program. Garlic with an unknown history may enter the program after 3 years of inspection. Foundation and Registered Stock is inspected and tested for Stem and Bulb Nematode, Ditylenchus dipsaci, and White Rot fungus, Sclerotium cepivorum. Certified stock is inspected for White Rot fungus.
Strawberry Registration & Certification
The Strawberry Program is a voluntary multi-step clean stock system adopted in 1949. At the top step, Foundation Stock is 100% tested for diseases of concern, and stock moves down (Registered) and out (Certified) of the system through subsequent growing seasons. Nursery stock at all levels of the program is inspected and tested for viral, fungal, and bacterial pathogens, nematodes, and varietal purity.
