My Lords, they are blessed with this psyllid, Aphalara itadori, and that is where we got it from. The issue is to ensure that it is as effective under our conditions as it is under Japanese conditions.

My Lords, is it not important that the Government take great precautions to prevent the importation of things such as Japanese knotweed? Such things do not just arrive; they are brought in. I know that there have been discussions at European level on the control of imports of plants; for example, Ash plants that might affect our trees, and many others. That is crucial because once Japanese knotweed gets hold, you cannot stop it.

My noble friend is quite right. A non-native species risk assessment of Japanese knotweed has been carried out under the GB non-native species mechanism. It is one of more than 50 risk assessments on plants that have been published. Japanese knotweed is assessed as high risk. There are many others. My noble friend will be aware that we are doing considerable work bearing down on pests such as this which are coming at us from abroad.
