My Lords, it is 30 years since Lady Sharples started asking questions about Japanese knotweed, and about 12 or 15 since I joined her, but all we get is the same answer every time: that this wonderful psyllid, Aphalara, will come galloping over the horizon and solve everything. It is absolutely clear that the problem of Japanese knotweed is getting worse and worse and causing more and more problems, and it is simply not being tackled. Do the Government agree that two things need doing? First, owners of land need to be put under a legal obligation to eradicate Japanese knotweed, and allowing it to grow should be an offence. Secondly, when transactions or contracts are made relating to land that has Japanese knotweed on it, or when people walk on it and may spread it, they should be notified that this dreadful, awful weed exists or has recently existed on that land.
