DEFRA consultation on and tax relief for Japanese Knotweed

Developers are well aware of the problems that the presence of Japanese Knotweed on a development site may cause.  The Government is consulting on a proposal to release an insect (Aphalara Itadon) as a biological control agent.  The insect weakens the plant by sucking its sap and is already used in certain countries e.g. Australia, USA and Canada.  Currently, the release is prohibited by UK legislation.  If anyone is interested in commenting on the DEFRA consultation you should submit your comments to DEFRA by 19th October 2009.  More details can be found on the DEFRA website (

The Government has also sought to provide financial assistance to developers by extending the Corporation Tax (Land Remediation Relief) Order 2009.  This means that the tax relief is now available to cover the costs of remediating land contaminated by Japanese Knotweed.
