Aphalara itadori to fight Japanese Knotweed in UK

Dr Dick Shaw of CABI told the BBC how the Japanese psylid, Aphalara itadori , has been found to be the most effective biocontrol for the invasive and agressive Japanese Knotweed, which was introduced to the UK by the Victorians. The psylid should only focus its attention on Japanese Knotweed and not other plants. The insect will be introduced on a handful of sites and closely monitored.

Click here to read the full BBC News story which includes a short video of Dr Shaw explaining how the insect fights the superweed; a timelapse video illustrating the plant’s speedy growth; and  a timeline map of the UK from the National Biodiversity Network showing the spread of Japanese Knotweed since 1890.

More information can also be found online at  DEFRA and the CABI Japanese Knotweed Alliance.
