Herbicide Treatment

Herbicidal treatment is often the best treatment for residential properties. This approach uses the application of herbicide to the Knotweed at the most appropriate times during the growing season.

We use glyphosate in most cases and we apply at regular intervals during the growing season. This is carried out over a three-to-five-year period. We can apply the chemical by spray, injection, or leaf wiping.

Injection or leaf wiping is useful when there is water or other plant and tree species nearby that we want to preserve.
