Wendel Lutz hardly qualifies as an anti-GMO activist. As a conventional corn and soybean farmer is nearly a polar opposite of an environmentalist. Yet, he shares some views with opponents of genetically modified foods based on his experience growing GM crops. [...] In his first year growing RR crops, he says, ”I had nice clean beans” with no weed problems.

But in his second year, he started seeing problems. ”We went from a 32 ounce formulation (with Roundup) to 36 ounces,” Lutz says. ”As time went on we were upping the rates,” he says.

Last year, Lutz grew Monsanto's Roundup Ready 2 Yield soybeans, but they didn't increase yields as promised. ”They were my worst soybeans,” he says. On top of that, weeds became resistant to Roundup, which was confirmed by lab tests on weed samples he submitted.
