(Reviewed 7/15)

In this Guideline:

The University of California's Foundation Plant Services offers pathogen testing on a fee-for-service basis for 16 different pathogens. Testing is performed using Polymerase Chain Reaction, which is one of the most sensitive methods for pathogen detection currently available. Testing is available for the following viral and bacterial pathogens of grapevines:

  • Grapevine leafroll-associated virus (1–5)
  • Grapevine vitivirus (A, B, & D)
  • Rupestris stem pitting-associated virus
  • Grapevine fan leaf virus
  • Grapevine fleck virus
  • Tomato ring spot virus
  • Arabis mosaic virus
  • Pierce's disease (Xylella fastidiosa)
  • Phytoplasmas
  • Grapevine rootstock stem lesion-associated virus (formerly know as Redglobe virus)

For more information call the Foundation Plant Services at (530) 752-3590.
