It’s a hoary bureaucratic trick, making a controversial announcement on the Friday afternoon before a long weekend, when most people are daydreaming about what beer to buy on the way home from work, or are checking movie times online. But that’s precisely what the US Department of Agriculture pulled last Friday.
In an innocuous-sounding press release  titled “USDA Responds to Regulation Requests Regarding Kentucky Bluegrass,” agency officials announced their decision not to regulate a “Roundup Ready” strain of Kentucky bluegrass—that is, a strain genetically engineered to withstand glyphosate, Monsanto’s widely used herbicide, which we know as Roundup. The maker of the novel grass seed, Scotts Miracle Gro, is now free to sell it far and wide. So you’ll no doubt be seeing Roundup Ready bluegrass blanketing lawns and golf courses near you—and watching anal neighbors and groundskeepers literally dousing the grass in weed killer without fear of harming a single precious blade.
Which is worrisome enough. But even more worrisome is the way this particular product was approved. According to Doug Gurian-Sherman, senior scientist at the Union of Concerned Scientists’ Food and Environment Program, the documents released by the USDA’s Animal and Plant Health Inspection Service (APHIS) along with the announcement portend a major change in how the feds will deal with genetically modified crops.
Notably, given the already-lax regulatory regime governing GMOs (genetically modified organisms, click here  for a primer), APHIS seems to be ramping down oversight to the point where it is essentially meaningless. The new regime corresponding with the bluegrass announcement would “drastically weaken USDA’s regulation,” Gurian-Sherman told me. “This is perhaps the most serious change in US regs for [genetically modified] crops for many years.”
Understanding why requires a brief history of the US government’s twisted attempts to regulate GMOs. Since the Reagan days, federal regulatory efforts have been governed by what’s known as the Coordinated Framework for Regulation of Biotechnology. Despite its name, the Coordinated Framework amounts to a porous hodgepodge of regulations based on the idea that overseeing GMOs required no new laws—that the novel technology could be effectively regulated under already-existing code.
Long story short, it means that the USDA theoretically regulates new GMO crops the same way it would regulate, say, a backyard gardener’s new crossbred squash variety. Which is to say, it really doesn’t. But that’s absurd. GM crops pose different environmental threats than their nonmodified counterparts. The most famous example involves the rapid rise of Roundup Ready corn, soy, and cotton, which were introduced in the mid-late 1990s and now blanket tens of millions of acres of US farmland. Spraying all of that acreage every year with a single herbicide has given rise to a plague of Roundup-resistant “superweeds,”  forcing farmers to apply more and more Roundup  and also resort to other, far-more-toxic products.  Crops that aren’t engineered to withstand an herbicide could never have created such a vexation.
