Septoria Resistance through Rootstock?

Greatgardens · December 9, 2020

Is it possible to confer Septoria resistance via (grafted) rootstock? If so, are there some varieties known to have such resistance? I'm thinking it's not possible, but couldn't find any info about it.

From my own experience with Septoria, plants seem to have little damage until heavy fruit set. Then it's downhill fast! That's what makes me consider the possibility.

A vigorous rootstock will keep the scion growing fast enough to overcome a lot of the septoria pressure. It is not exactly graft transferred resistance, rather is keeping the growing top of the plant as healthy as possible which tends to limit septoria.
