Little Weed, Big Problem

HIGH COUNTRY NEWS

A genetically modified grass is loose in Oregon. It could have been much worse.

In the failing light of an unusually warm January day, Jerry Erstrom and I race along a dirt track behind Rod Frahm’s white pickup. Here, near Ontario, Oregon, a stone’s throw from the Idaho border, Frahm grows onions, squash and corn. But today, he wants to show us something he’s growing against his will: a genetically engineered turfgrass designed for golf courses.

Frahm slams on the brakes next to a dry irrigation ditch, jumps out and yanks up a clump, winter-brown but laced with new green shoots. Beneath his gray fedora, his dark eyes glint with anger as he holds out the scraggly specimen. “I have it in a lot of my ditches,” he says.

Just to be sure, Erstrom produces a plastic vial the size and shape of a .22 caliber cartridge. He stuffs a few blades into it, adds water, and mashes the mixture with a wooden rod, like a bartender muddling mint. Then he inserts a plastic strip and hands it to me. It’s like a pregnancy test: One line confirms it’s working, while the other detects a gene that unmasks the intruder.

We wait, batting away gnats and breathing in the aroma of onions, whose colorful skins litter the county roads. Then the results appear: This is indeed the variety of creeping bentgrass that agribusiness giants Scotts Miracle-Gro and Monsanto engineered to tolerate the herbicide Roundup.
