Commentary
Thank you for this report, Jim.
Unfortunately, now that community members are becoming aware of this plant we are finding it and receiving reports of it all over the City of Hood River - often in sites like this one (a residential landscape setting). We really appreciate these reports because it helps us document the scope of the infestation. No control efforts have been found to be very effective. However, if this is your property or that of a friend, and there are only a few stems, it may be possible to dig this small patch out if it is done carefully and all tubers and stems are removed and bagged for disposal. Please wear gloves as many people have reported having poison oak-like symptoms from touching the sap of this plant.
Again, thanks for your report and sharp eyes! Jordan Kim Hood River SWCD

Remedy
Italian arum can be difficult to eradicate once established. Make sure to wear gloves and long sleeves and pants when removing it, as its sap can cause skin irritation. Do not compost or put in your yard debris, as this can lead to spreading of tubers which can grow into new plants. Home control methods can include carefully digging out the tuber and any daughter tubers and disposing in the trash. Cutting and disposing of the berries in the trash can help prevent spreading to new sites. Herbicide trials are still inconclusive, please contact your local Soil and Water Conservation District if you are interested in chemical control.
