Interpretive Summary:

Technical Abstract: The diseases reported under 'Virus and Virus-like Agents' in the first volume of this compendium, with the exception of Cherry rasp leaf virus and Rubus chinese seed-borne virus, should be considered oddities since there are no known type isolates available for these reported viruses. Without a positive control, one cannot test for these entities. When a suspected virus that has been reported in the literature has no known isolates, it is recommended that the name be dropped from use and from certification and quarantine documents. If a similar disease was observed in the future, there would be no means to compare it to something described in the past without an isolate. Thus, a new virus, if fully characterized, would be given a new name, and the use of the old name would continue to create confusion in the literature. In several cases, previously described, viruses have been characterized, and it is apparent that multiple names were used for the same virus based on symptoms in different cultivars. The disease names that are suggested for removal from any official list of disease of Rubus for quarantine or certification purposes include: Alpine mosaic agent, Bean yellow mosaic virus, Black raspberry mosaic virus (see Strawberry necrotic shock virus section), Black raspberry streak, Bramble yellow mosaic virus, Raspberry yellow spot, Thimbleberry ringspot virus, Tobacco necrosis virus and Tobacco rattle virus. Boyesenberry decline is now known to be caused by a nonviral pathogen.
