Sounds good, Ursula
In the long run it really pays to be careful with virus, so it's good you taken precautions.
While only having one casualty among lilies to virus so far, I have previously discarded dozens of Echinacea purpurea, hundreds of Primula, many peonies and among them a tree peony. I really miss the tree peony, but it had to go. Part of this problem was probably me ignoring signs for years and years, hoping for the best and while I was doing this infected plants, possibly dating back to the previous owners of the garden continued to be a source of infection.
This year I discarded all tulips of the cultivar Jan Reus after finding just one flower with broken colors. I also discarded bulbs of adjacent cultivars, just to be safe as tulips are cheap and I handle them a lot, increasing the risk of virus transferral. So now I'm a lot tougher with this, than I used to be as I know which problems it can cause.
