Japanese Knotweed

Baroness Sharples Excerpts

Monday 7th November 2016 Lords Chamber

Asked by

[Baroness Sharples]

To ask Her Majesty’s Government what progress they have made in controlling the spread of Japanese knotweed.

[The Parliamentary Under-Secretary of State, Department for Environment, Food and Rural Affairs (Lord Gardiner of Kimble) (Con)]

My Lords, we continue to explore bio-control options through the controlled release of the psyllid insect Aphalara itadori. Releases have been carried out at 18 sites this year using improved methods to increase the chances of establishment. Local action groups, some established with Defra support, continue to reduce or eradicate Japanese knotweed in several places in England. Community protection notices are starting to be used by local authorities to address the nuisance this plant causes.

[Baroness Sharples (Con)]

I thank my noble friend for that reply. Is he aware that I first asked this Question nearly 30 years ago? There has not been a great deal of progress. Is he aware of the man who killed his wife and committed suicide as he could not sell his property because of knotweed? Also, many people cannot get mortgages on their houses because of knotweed.

[Lord Gardiner of Kimble]

My Lords, first, I acknowledge my noble friend’s tenacity in seeking to deal with this brute of a plant. On mortgages, the Royal Institution of Chartered Surveyors published an information paper only last year that aims to help valuers and mortgage lenders better understand the implications of this plant for residential properties. We anticipate that this will lead to a more pragmatic approach between all parties in dealing with it. On what my noble friend said about the tragedy, this invasive species of plant is of great concern and we need to deal with it where we can.
