Herbicide Application Treatments we provide

• Spraying
• Stem injections
• W**d wiping
Advantages of herbicide applications
• Cost effective.
• Treatment can be carried out in-situ without the risk of spreading the plant further.
• Quickly reduces the capacity of the plant to spread on/off site.
• Quickly eliminates the capacity of the plant to impact built structures.
• Easy to administer.
Japanese Knotw**d can be treated in situ with the use of herbicides, this is a far more cost effective method that typically costs just 10-15% of the price of excavation and removal from site by physical/mechanical means. Specialist herbicides are required and these are to be applied by competent and trained technicians.

Spray Treatment

The successful use of herbicides to eradicate knotw**d requires the expertise of the CSJK and the JK technician. It is important to ensure that there has been a detailed site risk assessment undertaken and the existence of drainage or water courses identified to avoid contamination with herbicides. Spraying is the most effective method of herbicide application, although several applications may need to be undertaken over a number of years, depending on the extent of infestation.
Spraying should be carried out between May and October with is considered to be the optimum period of application. Ideally 2/3 treatments would be applied during this period.

Stem Injection

This method of application is used during inclement weather conditions and is a method of injection of herbicide directly into the stem of the cane, between the first and second nodes.
This method is also used near water courses where the over spray/drift of airborne herbicide is eliminated.
Stems greater than 8mm diameter can be injected with the smaller stems being sprayed or w**d/leaf wiped.
Stem injection is applied by the use of specialist injection equipment and is a more labour intensive method of application.
This method can also be used near habitats where greater care is needed to protect habitats of wildlife.



Leaf Wiping



W**d wiping is when a hand held wiper/sponge is used to apply the herbicide onto the leaf surface of the knotw**d,
like stem injection, it does not affect the neighbouring vegetation and water courses.
It is an alternative option to the knotw**d injection of the stems when the stems are not thick enough.
W**d wiping is more time consuming and is only practical on smaller infestations.

Japanese Knotw**d Identification

Japanese Knotw**d rarely exceeds a height of 3M. It has shield-shaped leaves which are flat at the base and are carried on zig zagged stems, which are sturdy, purple spotted, hollow and bamboo - like with regular spaced nodes.
The flowers (only female in the UK and Ireland) which appear in late Summer or early Autumn,
are creamy white/colours and are formed in dropping clusters 8cm - 12cm in length.
In Spring, the emerging stems are green to red/purple with rolled leaves that uncurl as the shoots extend.
At the end of the year, the stems persist and the various shades of brown, sometimes with an orange tinge.
In external appearance, the rhizome is dark brown and slightly leathery.
It is brittle when fresh and snaps like a carrot and has a musty “antique store’ smell.
The interior is an orange/yellow colour, generally darker towards the centre. Lines often radiate from the centre.
At the base of the Japanese Knotw**d stems, an enlarged crown develops from which shoots and rhizomes emerge. The crown is hardy and lumpy in appearance and before the growth seasons it can possess pink/red-smooth-shiny buds.

Introduction to Japanese Knotw**d

Japanese Knotw**d is a tall vigorous plant. It is an invasive non-native plant pest and is considered one of the most problematic plant species in the UK and Ireland. The species was introduced to Britain in the mid 19th century as an ornamental plant for large gardens, prized due to its imposing size and sprays of creamy white flowers. By 1886 it was established in the wild and now it is widely distributed. As it is non native to the UK and Ireland, it is not exposed here to any of its natural enemies, such as insects, bacteria and fungi that feed and grow on and in it in its country of origin. The absence of these checks in conjunction with its highly invasive and competitive nature has facilitated the invasive spread of Japanese Knotw**d throughout England, Wales, Scotland and Ireland.
The plants well documented rapid growth rate is in relation to the upward growth of shoots at the beginning of the growing season. The rate of lateral growth, via extension of its root system (rhizome), is not well understood. The rate of spread will be dependant on the density and composition of the soiled the presence of built structures. Dense soil will usually limit the spread of the plant. New shoots can emerge from spreading rhizomes. Rhizome extension is generally limited to a 4M radius from visible above ground plants and a depth of 2M. However, growth of 7M beyond these limits and a depth of 3M for roots is achievable in favourable condition of soil, the distance of 7M is considered a safe distance zone.
