Genetically engineered crops continue to dominate soybean, cotton, and corn acres planted by U.S. farmers
Genetically engineered (GE) seeds were commercially introduced in the United States for major field crops in 1996, with adoption rates increasing rapidly in the years that followed. The two main GE trait types are herbicide-tolerant (HT) and insect-resistant (Bt). These traits can be added individually to seeds as well as combined into a single seed, called stacked seed traits. USDA, Economic Research Service (ERS) reports information on GE crops in the data product Adoption of Genetically Engineered Crops in the U.S. These data show that by 2008, more than 50 percent of corn, cotton, and soybean acres were planted with at least one GE seed trait. Today, more than 90 percent of corn, cotton, and soybean acres are planted using at least one GE trait. Traits other than HT and Bt have been developed, such as resistance to viruses, fungi, and drought or enhanced protein, oil, or vitamin content. However, HT and Bt traits are the most used in U.S. crop production. While HT seeds also are widely used in alfalfa, canola, and sugar beet production, most GE acres are occupied by three major field crops: corn, cotton, and soybeans.
