A week after Friends of the Earth reported the presence of GM oilseed rape 'weeds' on a Lincolnshire Farm Scale Trial site, biotech company Aventis has finally taken action.  The weeds - which were flowering - have now been destroyed. FOE wrote to Margaret Beckett, Secretary of State at the Department of Environment, Food and Regional Affairs (DEFRA) on the morning of Friday 30th  November informing her of the presence of the GM weeds at the Witham-on-the Hill farm scale trial site. The Government's GM Inspectorate delayed visiting the site until Monday 3rd  December.  It reported to DEFRA on Tuesday who ordered Aventis to destroy the weeds on Wednesday 5th  December.
