Which GMO crops are grown in the US?

As of 2015, over 90% of corn, soybean and cotton crops grown in the US are GMO crops. Corn and soybean make it into the food supply, and there is no consensus among scientists regarding the safety of foods that are Roundup Ready or that contain the Bt Crytoxin.

GMO crops in the US below through 2012.
GMO crops 2000-2012. From

As of 2015:

  1. 92% of corn planted in the US is GMO. 
  2. 94% of cotton is GMO. 
  3. 94% of soybeans is GMO. 
  4. GMO crops grown in the US:Alfalfa, canola, chicory, corn, cotton, flax, papaya, plum, potato, rice, soybeans, squash, sugarbeets, tobacco, tomato.
  5. GMO crops grown in Canada: canola, maize, soybean, sugar beet.

From ISAAA (International Service for the Acquisition of Agri-Biotech Applications)  Brief 49-2014 Executive Summary:
  1. In 2013, 27 countries planted 175 million hectares, in 2014 18 million farmers in 28 countries planted  more than 181 million hectares in 2014
  2. This Executive Summary also gives a table of countries growing biotech crops in order of millions of hectares. US is #1 on the list followed by Brazil, Argentina, India and Canada. This table also lists which GMO crops are grown in each country. 
  3. Biotech crop usage has increased from 1.7 million hectares in 1996 to 181.5 million hectares in 2014.
  4. "...on average GM technology adoption has reduced chemical pesticide use by 37%, increased crop yields by 22%, and increased farmer profits by 68%."
  5. Farmers agree their productivity and profits have increased, thus there is an almost 100% replant rate. (But that's not the whole story, a significant chunk of these farmers are desperately poor and hungry, trying to feed a burgeoning population any way they can. They cannot afford to look at long-term consequences.)
The ISAAA country table is reproduced here.

Other GMO Crops:
Alfalfa, Canola, Cotton, Eggplant (Bangladesh), Papaya, Pepper, sweet, Potato called Innate™, Soybean, Squash (on Monsanto's page it looks like zucchini), Sugarbeet, Tomato.

* Not all these crops are Roundup Ready or contain the Bt Crytoxin, the 2 major concerns of GMO crops.

RR (Roundup Ready) Crops in the US: 
Alfalfa, canola, corn, cotton, soybeans, sugarbeets.
Specific brands: Roundup Ready soybeans, Roundup Ready Corn, and Liberty Link corn.

Bt crops containing the Bt Crytoxin:
  1. Bt-potatoes, Bt-corn, Bt-sweet corn.
  2. A type of Bt corn called Starlink™ generates the Cry9a toxin.
