I’m frequently asked about the difference between Japanese knotweed control and Japanese knotweed eradication.
The following definitions of control and eradication may be helpful:
Control – to limit, to curb.
So in terms of Japanese knotweed control, the intention of the (typically herbicide) programme is to limit the spread, curb its growth and ultimately to achieve local eradication.
Eradication –to obliterate, to destroy or remove completely.
Japanese knotweed eradication can be achieved either through the complete removal (to licensed landfill) of all the contaminated land or through a long term herbicide programme (control leading to complete destruction of the plant(s) through chemical means).
The Environment Agency’s Code of Practice ‘Managing Japanese knotweed on development sites’, discusses the use of herbicide programmes and makes clear that they should continue for a minimum period of three-years and often longer to achieve eradication. Critically they also state that the lack of surface growth should not be seen as proof that the plant is dead. Monitoring may be required for some time to ensure that the knotweed has been eradicated.
