Our Spray treatment offers the most cost-effective method for the treatment of invasive weeds.

If you have Japanese Knotweed contaminating your land, then the cheapest and most cost-effective way to tackle it is our JKS spraying process.

Using Dunton’s specialist chemical solution, the spraying process would be carried out during the knotweed’s growth season, typically from Spring to Autumn.

We carry out 4 separate spray processes each year and in most cases, the Japanese Knotweed will be effectively treated after two growth seasons, therefore timescales for this process can range from 12-24 months.

As part of our guarantee, we then monitor the subsequent area for a further 12 months to ensure that treatment has been successful. If you require faster treatment for your Japanese Knotweed then our Eradzion8 excavation and removal process would be better suited, with typical timescales being 4-6 weeks.
