Herbicide Use in Japanese Knotweed Management and Non- Native Tree Control Under Spotlight In New White Papers

We have launched two White Papers, giving a comprehensive insight into both the control and care of trees in invasive weed management programmes and the use of herbicides in Japanese knotweed control.

The White Paper offering guidance to dealing with trees offers an in-depth guide to controlling invasive, non-native trees, such as Sitka Spruce and Lodgepole Pine. The document also provides information relating to the protection of native tree species, offering guidance on how activities such as the use of herbicides and site access – including excavation work – can be controlled under weed management programmes when tackling plants such as Japanese knotweed.

The information works in tandem with the other White Paper, covering herbicide treatment in the control of Japanese knotweed.

These White Papers are the latest reference material produced by the PCA’s Invasive Weed Control Group – set-up in 2012 to signpost consumers to professional treatment companies offering assurance, standardisation and certainty in tackling the problem of species such as Japanese knotweed, giant hogweed and other environmentally and economically damaging pest plants.

The PCA worked with the Royal Institution of Chartered Surveyors (RICS) – supported by the Council of Mortgage Lenders and The Building Societies Association – together with Japanese Knotweed control companies that currently operate within the UK, to develop the Invasive Weed Control Group.

Since then the group has developed a national framework, a bespoke training programme and produced a range of material to underpin best practice within the invasive weed control sector.

Steve Hodgson, Chief Executive Office of the PCA, said: “Our guidance notes provide a useful reference to professionals in the invasive weed control sector, as well as those involved in the management and specification of invasive weed control projects. The guidance notes have been developed by highly knowledgeable experts. These are practical and robust guides, which can be used as a point of reference by professionals including those in surveying, construction and property development, as well as the landscape, amenity and remediation sectors.”
