    By Belinda Martineau, PhD Some Ag-Biotech history Twenty years ago, before crops genetically engineered to be herbicide-tolerant were commercially available, one of the big concerns environmentalists had about the use of agricultural biotechnology was that it would lead to "super weeds." Their apprehension stemmed from biotech products in the industrial…
  4. The Rise of Superweeds—and What to Do About It Source: Union of Concerned Scientists. It sounds like a sci-fi movie: American farmers fighting desperately to hold back an onslaught of herbicide-defying "superweeds." But there's nothing imaginary—or entertaining—about this scenario.

    Superweeds are weeds that have built up a resistance to the effects of herbicides used in agriculture to kill them. Weeds such as marestail (horseweed) and palmer amaranth (pigweed) are rapidly growing problems for farmers, pushing them to apply more herbicides, like 2, 4-D and Roundup, more often. These products have been shown to harm human health and the environment and their increased use ...
