【 摘 要 】

Genetically engineered (GE) crops (mainly corn, cotton, and soybeans) were planted on 169 million acres in 2013, about half of U.S. land used for crops. Their adoption has saved farmers time, reduced insecticide use, and enabled the use of less toxic herbicides. Research and development of new GE varieties continues to expand farmer choices.
