Knotweed Treatment

Acme Arb Ltd now carry out professional surveying and treatment of Japanese Knotweed

There are several ways to control Japanese Knotweed and we will assess the most suitable method for the given site and circumstances.

Once the extent of the problem been established, we can advise on the the most effective methods of control and elimination.

Here’s an outline of the main methods:

Herbicide Treatment Plan – Control and eliminate Japanese Knotweed
This plan is typically required by Residential and Domestic clients and includes:
A Japanese Knotweed Treatment Plan detailing the number of visits and the type of herbicide to be used and associated costs.

Chemical control is often the most cost efficient means of destroying invasive plants. An appropriate herbicide is either sprayed, injected or wiped onto the above ground part of the weed in order to kill the plant by a trained and qualified operative.

Japanese Knotweed requires multiple applications to fully eliminate and this will be outlined in the Herbicide Treatment Plan.

Full Site Survey and Japanese Knotweed Management Plan
This plan is typically required by developers and commercial organisations and includes:

-A full description of the site, mapping of the extent of infection and the provision of photographic evidence

-Consideration for the future use of the site

– Management objectives

-Risk assessment (environmental and legal considerations)

-Elimination procedure method statement – developed from the findings of the survey and coupled with any management requirements

-Ongoing works to prevent spread

-Support and general instruction to ensure control is effective

Full cost schedule and breakdown for the works to be carried out by Acme Arb Ltd

Site survey costs will vary and a site inspection will be required to confirm.

The other methods of invasive weed control are:
On-site burial
Invasive weed contaminated soil can been excavated and buried on-site. This will have to be to a specified depth within a fully lined burial cell to avoid any regrowth.

On-site bund formation and subsequent chemical treatment
Invasive weed contaminated soil can be stock piled on an impermeable membrane on site. Outside of the construction/operation area. Regrowth of weeds on the bund can be controlled using chemicals for an extended period.

Off-site burial (‘dig and dump’)
Invasive weed contaminated soil will be excavated and removed from site. The contaminated waste must be disposed of in accordance with current legislation at an appropriate licenced site. This is generally the most expensive control method.
