Monsanto is introducing a new feature for its geneticall modified corn seeds that it says will not only boost yileds but cut down on fertilizer use and carbon dioxide emissions. They have developed a coating for seeds made from a friendly fungus that helps corn plants in their earliest growth stages. Corn crops treated with the new Monsanto-Novozymes microbial -- officially known as Acceleron B-300 SAT -- had better yields than those without the treatment, the companies said in a statement Monday. The product stays on seeds longer and is compatible with other chemical treatments, unlike previous versions. It could be applied to more than 90 million acres (36 million hectares) by 2025.
