Scientists Find a Solution to Fight the Japanese Knotweed Menace in Britain

Britain has been invaded……by an alien plant species. Japanese Knotweed (or Fallopia Japonica) has spread with ferocious speed across the UK.

It has undermined buildings, destroyed flood defences and overwhelmed private gardens and public parks. Tackling it is costing millions of pounds. But now scientists have come up with a simple solution -- Aphalara itadori -- a sap-sucking insect that devours the dreaded knotweed. Scientists from the Centre for Agriculture and Bioscience International have asked for government permission to introduce the insect. If they get the go-ahead, it will be the first time that a bio-control technique involving a natural organism to control a pest will have been used in Europe. From London Stephen Beard ( or Stephanus Barbus) reports.
