The Welsh Government continues to work with partner organisations and the public to tackle the threats of invasive non-native species, which continue to have significant environmental, social and economic impacts in Wales. On Japanese knotweed, we have funded innovative trials with its natural psyllid predator and chemical treatment research. 58

Can I thank the Minister for that response? We have problems with a number of non-native species, but in my part of the world, Japanese knotweed is far and away the most problematic. Can the Cabinet Secretary provide an update on the trials that are taking place with the natural predator—I note you avoided trying to pronounce its name as well; I'm doing the same—and any progress with chemical treatments, because it really does cause a blight on houses, on areas, and makes houses unsaleable, and makes some of them dangerous?59

I thank the Member for his question. I know you've been vociferous in representing your constituents and communities in raising this area, and you're right, it does cast a blight on our buildings and on our local environment. I do notice I get the formal words for these—it does take you a while to get your tongue round some of them. I'm learning quickly on that.

You asked about the data in terms of the trial. Swansea University is currently analysing the data from their initial two-year chemical control trial, with the aim of producing technical advice to help tackle Japanese knotweed. I look forward to reading the final report, as I'm sure the Member will look forward to too. I can also confirm that the Welsh Government has provided additional funding for the Centre for Agriculture and Biosciences International to continue the psyllid project for 2017-18.
