I suppose it could have arrived that way. And maybe an extra "dip" might help, although, IMHO, 'dipping and/or soaking"have very limited usefulness as insect, or disease control. Once a disease is in the plants vascular system, all the dipping in the world won't affect it very much! It does serve a purpose in helping treat surface injuries, keeping virus, bacteria, and fungi from "attacking" the wound. I would bet that rhizome WAS dipped, before the donor sent it to HIPS, for the sale.It's my understanding that the fungal spores are almost everywhere in the soil, and only become a problem when weather, or soil conditions are "right " to allow it to attack a weakened plant....Arlyn
