Putting Japanese Knotweed Control into Context

Where Japanese knotweed eradication is required the control program must include monitoring since eradication will never occur unless the root (rhizome) is in a state of advanced decay. Too often so-called specialists will mislead clients into thinking that Japanese knotweed is eradicated once there is no top growth.
