If a batch of hostas contains any individual plants that show HVX symptoms, the whole batch should be considered infected and should be destroyed, as individual testing is impractical and not a guarantee. This virus is transmitted primarily through cutting the plants. Contact of the infected plant's sap with sap of a healthy plant will infect the new plant.
This can happen whenever cuts are made and the instruments or hands are not disinfected afterwards. Dividing hostas, removing bloom scapes, removing leaves, stepping on them, even accidentally running the lawnmower over them can and will spread this virus. It survives only in living plant tissue and dies without a host. Plants in pots may be simply disposed of or burned.
Plants in the ground should be dug carefully as to get as many roots as possible, and the spot should not be replanted until any remaining roots have died and rotted away.

Virus testing kits from companies such as Agdia, Inc. Note that several other plant viruses can affect hostas; therefore a negative HVX test result does not guarantee that your plants are totally virus-free. Whether or not your new hostas are pretested for HVX, keep them isolated from other hostas in your garden for several weeks and watch new plants for symptom development as they adapt to their new environment. Once hostas are established in your garden, try to minimize any wounding that could release sap and provide an entry point for HVX.
After working with individual hosta plants, wash your hands thoroughly with soap and water. Also, decontaminate any items e. These ingredients can be ordered on the internet.
