After testing the effectiveness of several popular brands of UK approved pesticides. We can confidently recommend Icade as the first step in a Japanese Knotweed control programme.

The standard application is 100ml of Icade per 5 litres of water, applied as a medium/fine spray  to well-developed foliage to the point of run off.

Follow up treatment may be required, if there are any signs of re-growth.

Icade has almost no odour, and is able to treat a multitude of invasive plants that are not only unsightly, but can also damage building structures and kill surrounding plant life.

Once applied, Icade is rain fast within an hour, and can also be used to treat Buddleia.
