The virus, unless it was in the graft, comes onto the foliage through mites. It works its way down the cane to the bud union, or roots in that case. No I just got rid of the whole thing, and am still looking for the smaller roots. I really dont think the hairy roots are that much to worry about, but its hard to get all the roots. In my case it was not in the grafted canes yet. If it is an old rose, you might want to replace soil anyway. The concern about roots might be that multiflora can grow from a small root, and many grafted roses in the NE and Canada are on multiflora. Every body is trying to go own root as much as possible because of the infection in MF.

Ann, the virus has been found in Bossier City (just about on I-20). http://bestofswla.com/2015/12/03/witchs-broom/ "Bossier shares most aspects of its climate with its sister city of Shreveport. The city has a humid subtropical climate (Köppen climate classification Cfa) with hot, humid summers and mild winters. During the warmer months, the city is prone to severe thunderstorms which feature heavy rain, high winds, hail, and occasional tornadoes. The city has a slightly above average rate of tornadoes when compared to the US average.[15] Due to the flat topography of the city and the prominence of smaller waterways that are prone to backwater flooding from the Red River, the city occasionally experiences severe flooding events. A notable occurrence of severe flooding occurred in March 2016 after torrential rains caused a rapid rise of many local waterways, displacing upwards of 3500 people from their homes across the area.[16][17] Freezing and ice storms occasionally occur during the winter months." https://en.wikipedia.org/wiki/Bossier_City,_Louisiana

I am SOOOO sorry to hear. RRD was one of my concerns that sorta kept me growing roses years back Right now, I think I might have boxwood blight. Took some cuttings for analysis to get confirmation. Sadface on , as these boxwoods I have nurtured since they 3G sized to full grown....and they grow like a measly few inches per year at most. I hate the diseases we speak about cause it's not a single plant virus/disease. It can setback your hardscape by wiping out X Y Z
