Yes, but it depends how far up into the vascular system the pathogen traveled. If it got to the meristem (it's very tiny, center of the plant) you're screwed. I have saved ~2 before. Otherwise, I like Dip N Grow, not for any rooting potential whatsoever, but because the solvent is ethanol, which is a great sterilant. First step is getting it sterile, then just leave it completely dry and see what happens. I like to blot off every last iota of water before I bury the plant, even in dry media.
