Adoption of Genetically Engineered Crops in the U.S.


U.S. farmers have adopted genetically engineered (GE) crops widely since their introduction in 1996, notwithstanding uncertainty about consumer acceptance and economic and environmental impacts. Soybeans and cotton genetically engineered with herbicide-tolerant traits have been the most widely and rapidly adopted GE crops in the U.S., followed by insect-resistant cotton and corn. This data product summarizes the extent of adoption of herbicide-tolerant and insect–resistant crops since their introduction in 1996. Three tables devoted to corn, cotton, and soybeans cover the 2000-09 period by State. See more on the extent of adoption...

Adoption of GE crops has grown steadilty in the United States since their introduction in 1996.


The following tables provide the data obtained by USDA's National Agricultural Statistics Service (NASS) in the June Agricultural Survey annually for 2000 through 2009. Randomly selected farmers across the United States were asked if they planted corn, soybeans, or upland cotton seed that, through biotechnology, is resistant to herbicides, insects, or both. Conventionally bred herbicide-tolerant varieties were excluded. "Stacked" gene varieties are those containing GE traits for both herbicide tolerance (HT) and insect resistance (Bt).

According to NASS, the States published in these tables represent 81-86 percent of all corn planted acres, 87-90 percent of all soybean planted acres, and 81-93 percent of all upland cotton planted acres (depending on the year). See more on the extent of adoption.
