How to act
Effective control can be achieved using foliar spraying with a broad leaf herbicide, but no registered herbicides can be used on or near water. Hand pulling and digging out of runners for small infestations will require repeat removal when regrowth occurs. Preplanning of revegetation including mulching can assist in control. As it can reproduce vegetative from a small segment care should be taken to dispose of waste by burning or placing in black plastic bag and leaving in the sun for at least 48 hours.
