Each Knotweed infestation will have its own unique problems. Our assessors will formulate and advise on an optimum plan to suit the situation. This could involve one or a combination of our proven methods: stem injection, soil application, foliar spraying or wiping. On an overgrown site complete clearance followed by chemical treatment of regrowth could be the answer. Waste removed is taken to a licensed incinerator or landfill site for disposal.

At present, there is no product available guaranteed to kill Japanese Knotweed with only a single application. Because it is necessary to kill off all of the plant's extensive rhizome system, Knotweed eradication can take several applications over a prolonged period of time.

Treatment through purely chemical means would take on average, two to three years but occassionally a single treatment will suffice.
