Japanese Knotweed (Fallopia Japonica, Renoutria Japonica or Polygonum Cuspidatum) was first introduced into Britain in the 19th century with the purpose of being an ornamental plant. Over time though it has become widespread in many different habitats, including roadsides, riverbanks and derelict buildings. It outcompetes native plants and animals.
Under The Wildlife and Countryside Act 1981 London Japanese Knotweed is now a controlled species and, as such, soil contaminated with its rhizomes must be disposed of appropriately and it is an offence to allow it to spread to other land.
Methods of Control
- Stem injection targets the application of a controlled quantity of herbicide directly into the core of the plant between the second and third nodule. This direct targeting of the herbicidal application enables stem injection to be the least insidious method of eradication of this troublesome weed.
- The stem injection is normally undertaken when the plant is dying back as it then draws the herbicide into the root system. Unlike traditional spraying methods, the injection system is not weather dependant i.e heavy winds or rain.
- Stem injection can 100% be safely applied in an area where Tree Preservation Orders have been issued and where there are environmental constraints.
- Stem injection has no impact on any surrounding vegetation or wildlife. Stem injection is accepted and authorised by the E.A. to use on organic approved farms, without causing the loss of their organic status. Due to the labour intensiveness of stem injecting it is really on used on smaller sites or sites that carry environmental constraints such as water courses and or tree preservation orders.
- This is perfect for large infested sites that have no environmental constraints. The herbicide is applied directly to the plant and absorbed through the leaf and into the rhizome.
- Knapsack applications are dependent on weather conditions. All herbicide applications are carried out ‘in-house’ by our NTPC PA1 & PA6 qualified staff.
- To eradicate this invasive plant requires an understanding of its growth and legislation
Accurate Reporting & High Levels of Communication
Our team of pest control technicians ensure that a constant stream of communication & accurate reporting with all of our clients is given. This high level of communication enables us to highlight any environmental, hygiene or proofing issues which could be conducive to continued pest activity at the earliest possible stage.
The removal of these issues will result in the elimination of further infestation and will also provide our clients with a welcome knock-on effect of significantly reducing the prospect of on-going costs.
For our commercial clients, we also devised a ‘real time’ electronic field reporting system which allows our field service staff to input site data such as infestation, hygiene and proofing / defects into hand held PDA’s. This data is then immediately transmitted to our server which allows our clients to remotely can log into our system via a secure code and download all data / site reports pertinent to that or recent inspections. This service has resulted in some tremendous levels of feedback from our clients.
