Somewhat off topic . . . . We can move to another thread if necessary. . . .

Do you think that susceptibility to SDS is a trait of the variety? If so, why do you think so? For example, have you lost more than one tree from a specific name?
-
Is SDS one thing atttributable to a single pathogen? If so, what is the nature of transmission? I was under the impression that SDS infects the (tolerant) DV rootstock, so the pathogen is transmitted thorugh the graft. Is that wrong?
-
Does an infected rootstock that is removed and destroyed leave behind the pathogen, e.g. a soil-borne fungus?
Thanks!
Edit: I saw your post (above) linking to the prior discussion. To my knowledge, SDS is not common here in the Northeast. There’s no population of wild DV trees except in a very few isolated places. But I lost a recently purchased tree last year, and i’m wondering whether I may have permanently introduced a pathogen than can now affect my other trees.
I guess i have to ask: For your trees that died, is there one source of rootstock or many? In my case, i have had no problem with rootstock purchased from Missouri or from trees purchased from Stark’s, England’s, JF&E, or Burnt Ridge. My one fatality was purchased from OGW.
