Interpretive Summary:

Technical Abstract: As a perennial crop propagated vegetatively, grapevines are exposed to a diversity of pathogens, including viruses responsible for important diseases detrimental to wine, juice, and table grape production. Four major disease complexes of viral etiology have been described, each caused by a different set of viruses existing as multiple strains: grapevine leafroll disease (GLD), rugose wood disease (RWD), infectious decline, and fleck disease. Understanding the genetic variability of the different disease complexes in Pacific Northwest (PNW) is crucial to the development of accurate methods of detection, as well as for clean plant programs supplying the planting material in the PNW. The specific detection tools were based on RT-PCR and RT-qPCR tests and compared with and validated against other detection systems like ELISA to ensure their reliability.
