Japanese Knotweed

Lord Campbell of Alloway Excerpts

Thursday 24th June 2010 Lords Chamber

[Lord Henley]

My Lords, we are all aware that my noble friend has been pursuing this matter for about 20 years. This is an experiment worth doing. We have put a great deal of research into the safety of the psyllid that is being introduced to ensure that it will not eat anything other than Japanese knotweed. So far, as far as we know, it does not. If we find any evidence that the psyllid moves off, we will quickly eradicate it to ensure that it does not cause the damage that uncontrolled releases of biological agents can cause.

[Lord Campbell of Alloway]

What has been done about it over the past eight years?

[Lord Henley]

My Lords, a great deal has been done about it. I notice that the noble Lord, Lord Hunt of Kings Heath, is laughing, because he has had to address these questions before. I am grateful for the work that the previous Administration did in this area in introducing research into the said psyllid, the—let us get the name right again—Aphalara itadori. We hope that it will do the appropriate job in due course.
