GE CORN AND COTTON WITH BOTH HERBICIDE AND INSECT RESISTANCE ARE NOW THE NORM
Source: USDA news release

Genetically engineered (GE) seeds are widely used in U.S. field crop production.

Herbicide-tolerant (HT) crops were developed to survive the application of certain herbicides that previously would have destroyed the crop along with the targeted weeds.

Insect-resistant crops contain a gene from the soil bacterium Bacillus thuringiensis (Bt) that produces a protein that is toxic to specific insects.

Seeds that have both herbicide-tolerant and insect-resistant traits are referred to as "stacked."

Recent data show that the adoption of stacked corn varieties has increased from 15 percent of U.S. corn acres in 2006 to 76 percent in 2016.

Adoption rates for stacked cotton varieties have also grown, from 39 percent in 2006 to 80 percent in 2016.

Generally, many different GE traits-each aimed at a specific herbicide or insect-can be stacked; varieties with three or four GE traits are now common.

Research suggests that stacked corn seeds have higher yields than conventional seeds or seeds with only one GE trait.

This chart is based on data found in the ERS data product, Adoption of Genetically Engineered Crops in the U.S., updated July 2016.
