Editor's Pick 2015, #6:<br>Genetically engineered seeds planted on over 90 percent of U.S. corn, cotton, and soybean acres

U.S. farmers have adopted genetically engineered (GE) seeds in the 20 years since their commercial introduction, despite their typically higher prices. Herbicide-tolerant (HT) crops, developed to survive the application of specific herbicides that previously would have destroyed the crop along with the targeted weeds, provide farmers with a broader variety of options for weed control. Insect-resistant crops (Bt) contain a gene from the soil bacterium Bacillus thuringiensis that produces a protein toxic to specific insects, protecting the plant over its entire life.
