JAPANESE KNOTWEED REMOVAL
Stem Injection
Stem injection is an alternative to foliage spraying, which can affect other nearby plants. By injecting a concentrated dose of Glyphosate Herbicide into each individual cane using equipment specifically designed for the treatment and eradication of Japanese Knotweed.
This method of direct injection of herbicide is highly effective as it is absorbed throughout the rhizome and deep into the plant’s root system, helping to completely eradicate the troublesome plant.
Stem injection is far less risky to both to the environment and neighbouring plants.
How long does herbicide spraying take to work?
Herbicide spray treatment is a sure and economically viable method of eliminating Japanese Knotweed but it may take a while. Once the herbicide has been applied to the leaves, it needs to be taken down to the rhizomes to be effective. The herbicide is usually rainfast within 10 mins. Spray herbicide treatments normally take between 2 and 5 years to complete, but can take longer if the infestation is mature and well established.
Accreditations
- PCA approved
- Trust Mark
- BALI approved
- Treated 1000’s of properties
- Approved by councils
In environmentally sensitive areas, for example where the Japanese Knotweed is on or near water, we will treat that too. Using the stem injection process will minimise any risk to water and the environment.
We’re experienced in surveying and the licensing requirements – and ensure that all relevant documentation is completed as per the PCA and Environment Agency’s guidelines.
