WASHINGTON - Two leading US anti-trust experts have published a white paper warning against a possible merger between Bayer and Monsanto, arguing that such a move would see a new Bayer-Monsanto conglomerate controlling nearly 70 per cent of the cotton acreage in the United States. The former Justice Department officials from the US Antitrust Division also claim the new corporation would likely lead to higher input prices, with less choice and higher food prices for consumers, and fewer non-biotechnology options available to farmers and consumers.
