German company Bayer CropScience blamed Government constraints for its decision which, it said, would make the GM maize crop "economically non-viable". The company was the only one eligible to grow the genetically modified maize Chardon LL in the UK. The move is likely to put an end to GM crop growing in this country for "the foreseeable future", a spokesman for the Department for Environment, Food and Rural Affairs said. In a statement, Bayer CropScience said Government-imposed conditions would stall GM maize production for too long.
