A vital ingredient in mince pies, biscuits and stuffing -- and of course a large amount fed to turkeys, the future of Christmas dinners containing wheat could be at risk, with the persistent weed making its way across British fields.

Black-grass (Alopecurus myosuroides) is a native annual weed which although natural, large infestations in farmers' fields can force them to abandon their winter wheat -- the UK's main cereal crop. Farmers have been using herbicides to try and tackle the black-grass problem -- but in many areas of England the agricultural weed is now resistant to these herbicides. The cost of black-grass heralded as 'Western Europe's most economically significant weed', is setting back the UK economy £400 million and 800,000 tonnes of lost wheat yield each year, with potential implications for national food security.
