Japanese Knotweed

Lord Greaves Excerpts

Tuesday 7th November 2017 Lords Chamber

[Lord Greaves (LD)]

My Lords, I pay tribute yet again to the noble Baroness, Lady Sharples, for her persistence in this matter. I am very sorry she cannot be here today and, if she is poorly, I hope she gets better as quickly as possible. The Minister referred to a two-pronged approach but over the years the Government have put too much hope on the prospect of armies of jumping psyllids crossing the land, chewing the knotweed in their path and getting rid of it. That will not be the answer, not for a long time at least. Is not the answer in the short run the work of local action groups, local authorities and others, to which the Minister referred? Is it not the case that the Government ought to be giving a lot more strong advice to local authorities to get on with it, because this stuff can and ought to be removed?

[Lord Gardiner of Kimble]

There are good examples of where local action groups have worked effectively and eradicated Japanese knotweed. In Defra we have an official who is co-ordinating the work of the local action groups. I very much endorse their work and think it is the way forward. However, research shows that we should be looking for a more robust psyllid. We have released in 16 sites this year 120,000 psyllids and I hope we will see some progress in that regard.
