A variety of canola is the first genetically modified plant to escape into the wild and flourish. It’s growing wild in North Dakota ditches. This could lead to problems:
Less than 1 percent of the studied plants were resistant to multiple herbicides, suggesting they have changed genetically in the wild. Seed industry representatives say such modifications are not a problem because crops and weeds have exchanged genes for millennia. But farmers and scientists worry that weeds that can resist several herbicides would increase the use of more toxic herbicides.
