Stem Injection & Leaf Application

Stem Injection provides a targeted treatment using concentrated doses of herbicide which are injected directly into the plant’s stems using specialised equipment. The herbicide is drawn down through the stem and penetrates deep into the rhizomes where it kills the plant. This method of control is particularly advantageous due to its lower environmental impact. When carried out professionally it poses minimal risk to nearby water and the surrounding environment making it a suitable alternative to herbicide spraying in environmentally sensitive areas. Stem injection is particularly useful for treatment in areas next to watercourses.

Direct injection into individual stems can be a laborious task particularly when covering larger areas however it has proven to achieve successful control in all forms and is still a cost-effective means of control. Our Japanese Knotweed technicians are skilled in delivering accurate doses to each plant ensuring a thorough treatment on each occasion. As with other herbicide treatment methods the process can take a number of years to completely clear an area of Japanese Knotweed and consistency of service is essential.

Trust JBB Knotweed Solutions to deliver a reliable and consistent service of the highest quality for the duration of your management plan.

Japanese knotweed stem
Leaf Application is carried out by using a small device to manually wipe each leaf with a coating of concentrated herbicide. This method provides a direct hit to the desired area with less wastage and run-off into the surrounding environment. It is a suitable option for small areas, immature plants or when the infestation is near desirable plants or conserved areas. Like other herbicide treatments leaf wiping targets the rhizomes and normally clears an infestation within 2-5 years. Weather conditions must be favourable for both herbicide spraying and leaf wiping to ensure a sufficient dry time for the herbicide is given. JBB Knotweed Solutions provide a variety of herbicide treatment options with a proven track record for controlling knotweed from a variety of residential and commercial settings.

Herbicide Treatment

Herbicide treatment involves the application of herbicide chemicals to the green foliage (leaves) using a backpack or handheld sprayer. It is suitable for both large and small areas, causing minimal disruption and inconvenience. The process of herbicide treatment is gradual and can take between 2-5 years to complete (longer for severe infestations).

5. Excavation with offsite disposal (main image)

Excavation and Off-Site
Disposal

Land contaminated with Japanese Knotweed can prove troublesome to developers and construction firms whose projects may be hindered until the knotweed is dealt with. Homeowners looking to build an extension or have their garden landscaped may require an immediate solution.

6. Excavation with onsite treatment

Excavation and On-Site
Treatment

On sites where additional space is available, excavated waste can be stockpiled in a segregated area where its presence will not pose any threat to surrounding structures or be at risk of spreading. A suitable management plan can then be put in place to treat the Japanese Knotweed with herbicide over a period of 2-5 years.

7. Root Barriers

Root Barriers

Root barrier membranes can be used as a means to prevent the spread of Japanese Knotweed onto neighbouring land.  The effectiveness of the membrane is determined by good installation, therefore, it is essential that a specialist contractor such as JBB Knotweed Solutions is involved to undertake the task. A failure to halt Japanese Knotweed from spreading onto neighbouring property could result in legal proceedings.
