Thanks Henry, have just glanced at the other places you had posted it on, more reading material.
Just out of interest is it possible that and RMV could be mis- interperated.

RMV (rose mosaic virus) is not an actual virus name but a group name for rose viruses that exhibit mosaic symptoms.

Henry can I use simple terms, the one that we/I associated with roses and this newish one could have the two been mis-interpreted priviously

Any that were called RMV were actually one (or more) of the actual viruses.

Title: Roses: virus and virus-like diseases.
Author: V. Lisa
Published in: Colture-Protette. 1998, 27: 5 Supplement, pages 35-38.
Abstract: "Notes are given on the viruses and virus-like diseases that are known to affect roses around the world. The most common and widespread virus disease is rose mosaic, associated especially with prunus necrotic ringspot ilarvirus (PNRSV), apple mosaic ilarvirus (ApMV), arabis mosaic nepovirus (ArMV) and strawberry latent ringspot nepovirus (SLRV), but also with tobacco ringspot nepovirus, tobacco streak ilarvius and tomato ringspot nepovirus. Tobacco mosaic tobamovirus and an unidentified closterovirus are found sporadically. The virus-like diseases of unknown aetiology include rose ring pattern, rose flower break, rose streak, rose rosette (or rose witches' broom), rose leaf curl, rose spring dwarf and rose wilt. Other disorders are caused by hormonal imbalances or other types of incompatibility between the graft and the rootstock of unknown aetiology, such as rose bud proliferation, rose dieback (or rose stunt) and frisure. Techniques for diagnosing viruses in roses and methods for their control are described."

Title: Characteristics of rose mosaic diseases

Author: Marek S. Szyndel

Published in: Acta Agrobotanica 57(1-2): 79-87, (2004)

Summary: "Presented review of rose diseases, associated with the mosaic symptoms, includes common and yellow rose mosaic, rose ring pattern, rose X disease, rose line pattern, yellow vein mosaic and rose mottle mosaic disease. Based on symptomatology and graft transmissibility of causing agent many of those rose disorders are called "virus-like diseases" since the pathogen has never been identified. However, several viruses were detected and identified in roses expressing mosaic symptoms. Current1y the most prevalent rose viruses are Prunus necrotic ringspot virus - PNRSV, Apple mosaic virus - ApMV (syn. Rose mosaic virus) and Arabis mosaic virus - ArMY. Symptoms and damages caused by these viruses are described. Tomato ringspot virus, Tobacco ringspot virus and Rose mottle mosaic virus are also mentioned as rose pathogens. Methods of control of rose mosaic diseases are discussed."

Thanks muchly Henry, you give some of us so much reading material. In your opinion Henry could they be wrongly diagnosed by the novice to the eye.

Any "eye" guess is only a guess and could be wrong.

Henry, it's a never ending battle, how many viruses produce the water mark pattern we call RMV, others the spotting ? I suppose exact identification doesn't matter for the nursery people, just cull everything showing any sign and keep renewing Multiflora understock mother plants by seed propogation.
I fortunately haven't seen a lot of the viruses you mention above but we do allow cut flower roses into our country so it's only time before these imports introduce all the problems.

Questions!
Can "Yellow Vein Virus" be controlled using the control method outlined above? Any chance of it blowing 200 yards on a stiff breeze like fungus, or is it passed on by contact through rind damage from infected plants or grafting.

Do you have any information on control or any case study links?

Perhaps when the Minnesota Ph.D. thesis becomes available, we will have some of these questions answered.

The following should be of historical interest to your area:
