Chemical Treatment
The most cost effective eradication method is a programme of chemical treatment. JKSL offer a robust strategy of chemical treatments, using chemicals and methods approved by the Environment Agency & SEPA, overseen by their BASIS qualified practitioner (ID - E/5787/ICMAH).
All chemical application operatives are trained to the highest NPTC standards demanded by strict UK regulations and monitored by the Company’s stringent quality control procedures.
When considering a chemical treatment, the environmental sensitivity of the site must be taken into consideration when selecting chemicals.
Residual Chemicals
Residual chemicals create a barrier within the soil which can remain for upto 2 years. The herbicide used is a broad leaved killer and is capable of killing Japanese Knotweed within one season. These chemicals are NOT approved for use near to water or in environmentally sensitive areas.
Non-Residual Chemicals
The only herbicide approved for use near water is Glyphosate. A WQM1 form must be submitted to the Environment Agency if this herbicide treatment is required within 5m of an open water course. Eradication with Glyphosate will require repeat applications over a 3 to 5 year period.
