> I thought with the right rootstocks the grafted was protected. Yes that's true. Grafted on PT you will have no problem with CTV but the plant still carries the virus and can transmit it to other citrus.
> How can I check that a variety grafted on a resistant rootstock has the virus? Maybe would be possible graft variety with suspicion to CTV onto Finger Lime seedling or graft finger lime and tested variety on one rootstock as a simple test? I found info about C. australasica extreme CTV sensitivity in the book The Genus Citrus.
