Interpretive Summary: This article summarizes the biological indicator plants commonly used in California for diagnosis of graft transmissible diseases of citrus and the requirements for conducting the indexing. The known graft transmissible diseases of citrus are briefly reviewed.

Technical Abstract: Biological indexing for the detection of graft transmissible diseases of citrus is essential for maintaining a citrus certification program. Many of the graft transmissible diseases of citrus are harbored as latent infections in the scions, but when propagated on a susceptible rootstock that allows expression of the symptoms in the whole tree, the results are devastating. The requirements for growing plants used for biological indexing, and the indicator plants commonly used for the detection of common graft transmissible diseases of citrus will be reviewed.
