Initial post 22 OCT by Margaret Furness
What's the current thinking on whether insects can transmit rose viruses? I bought a plant on impulse from a big-chain hardware about 10 years ago, and discovered that it was on a rootstock that rose nurseries had stopped using several decades ago. And eventually realised it was virused. Because the plant is thriving, I chose to ignore it. However, two cutting-grown roses next to it are showing virus.

I was always taught that anything that could penetrate a plants cell has potential to transmit a virus, whether it was an animal however large or small or your secateurs. How close are they, is there a possibility their roots could have become grafted together?

Thank you for the info and link.
I don't prune much. Perhaps it's the rosella parrots sucking sap from red new growth...
They're about 1.2m apart. I don't know whether R indica major would fuse roots with an Austin or a 1950s HT.
I have a nasty feeling I'll have to hoick all three, and start again - after the mass of buds on Apricot Nectar are finished.

Margaret, you might like to check out the Mosaic Virus section in the GLOSSARY. I have added part of the 1983 reference, which is certainly not “current thinking”, but it may help in making a decision re hoiking.

(I have just noted there is more to be read under: Rose mosaic virus RMV)

Thank you. I think 1983 is too old to gamble on; the next rose in line is Mrs A R Waddell.
