Monsanto is donating $4.7 million to the campaign to oppose GMO labeling in Colorado. The St. Louis-based agriculture company is a primary producer of genetically modified seeds. The No on 105 committee has raised almost $10 million through Sept. 24, with Pepsico and Kraft Foods also giving more than $1 million each. The group begins running TV ads against the initiative this week. Meanwhile, the supporters of the labeling initiative, Right to Know GMO, have raised about $323,000, including almost $120,000 in the most recent two weeks. That groups top donors are Food Democracy Action at $140,000 total and Dr. Bronner's Magic Soaps at $25,000.
