By 2001, ScottsMiracle-Gro and Monsanto had succeeded in creating Roundup-ready bentgrass, and in 2002 they applied to the Department of Agriculture (which regulates transgenic crops) for a permit to sell the stuff. The companies are still waiting for that approval - but they do have a permit to grow the grass. So in 2003, ScottsMiracle-Gro contractors planted transgenic bentgrass on 400 acres of high-desert farmland in Jefferson County, Oregon. At this point, the two companies had spent tens of millions of dollars on the project. The goal, says a ScottsMiracle-Gro spokesperson, was to produce a good supply of seed and have it ready to sell "the day they got approval."

When they find transgenic grass, the field scientists share its GPS coordinates with academic researchers and ScottsMiracle-Gro staff, and mark their map. Under a 2004 USDA mandate, ScottsMiracle-Gro must work to remove all known GM grass that has spread outside, or cross-pollinated with something outside, the original control area.
And spread it has: The pollen ranged up to 13 miles, perhaps farther. Despite efforts to prevent contamination - the company used tractors dedicated to the transgenic fields, stored and transported seed in closed containers, and employed other protection measures - transgenic grass migrated well beyond the boundary of the control area. Scientists, regulators, and farmers knew it would spread; grass, after all, is a wind-pollinated perennial. A few overlooked plants here and there are all it would take. "Any time you let something go to seed," Butler says, "you'll see a million where once there was one."
What was surprising, says Neil Hoffman, a risk analyst with USDA's Biotechnology Regulatory Services, was that the grass and CP4 gene traveled so far. The migration was driven by two factors. First, a heavy summer wind kicked up, depositing seeds onto neighboring farms and into patches of no-man's-land like drainage ditches. Second, the grass cross-pollinated with other species - red top, for instance - passing on the trait of glyphosate resistance. This kind of hybridization is what environmentalists most fear: Plants with a new, survival-boosting trait gain a competitive advantage that will launch them on a global ecological conquest, potentially disrupting whole ecosystems.
