The Japanese knotweed injector is currently being used by many knotweed treatment professionals, and plant and wildlife trusts. Offering a very competitive alternative to the vastly more expensive products out there.

Japanese Knotweed is an ever increasing problem. A highly invasive weed, it causes significant and costly damage to structures and surfaces, and most banks or building societies won’t lend on property with knotweed close to the house.

Japanese Knotweed, once seen as an exotic ornamental plant, has now become an invasive nuisance – so much so that it is an offence to plant or cause it to grow in the wild. Stem Injection has become an increasing popular, safe and effective way of control.

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 approximately 20-30cms from the base of each cane(between the 1st and 2nd nodule). Approximately 5mls of herbicide mix is injected into each cane. The application of glyphosate based products are most effective 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.

The stem injection system works by delivering a measured dose of concentrate herbicide into the centre of the plant rather than just to the surface. This means the treatment is extremely localised, only ever targeting the plants injected and preventing the environmental risk of drift spray, run off or contamination of watercourses and other sensitive vegetation. The weed will also absorb the concentrate into its rhizome (root) at a much faster rate than with folia spraying, providing a quicker resolution to the Japanese Knotweed problem.

Other traditional methods all have some practical flaws. Chemical spraying can harm other plants and wildlife in the area, is expensive and by no means 100%effective. Digging out the weed is even more expensive, must be repeated a number of times to remove any trace of roots or rhizonic growth and must be disposed of as hazardous waste, filling valuable landfill sites with huge quantities of contaminated soil.

So, the precise control, the speed and the practicality of an injection delivered herbicide appears to be the obvious solution. The fact that it can be applied in all weathers throughout the growing season of April to October has also been a major advantage - a silver lining to this summer's plentiful clouds, enabling treatment to carry on undeterred by the constant downpours.

Please note no herbicide is included and please following the instructions on the chosen herbicide used .


The weed is one of the most destructive plants in the UK.
