More recently I've read something about that again, too. Apparently the range of error is quite small before you begin cooking the bulb itself. Years ago, I remember Dr. Neil Anderson here at the U of Minnesota talking about that as a possible option. He says all Easter lilies in commerce have the Lily Symtomless virus (LSV), and in fact that is what contributes to keeping them short and compact. He is one of the breeders working on "everblooming" lilies that incorporate Lilium longiflorum (Easter lily) genes...... ought to be releasing something soon, I would think.
I also remember something about systemic acquired resistance (SAR)..... some other something sprayed on the plant that induces it. Was it aspirin?
I don't recall that it was specifically for viruses, though.
