Other GM crops grown in 2014 include Alfalfa (862 000 ha), sugar beet (494 000 ha) and papaya (7 475 ha). In Bangladesh a genetically modified eggplant was grown commercially for the first time on 12 ha. [6] The majority of GM crops have been modified to be resistant to selected herbicides, usually a glyphosate or glufosinate based one.
Genetically modified crops undergo a significant amount of regulation throughout the world. For a GM crop to be approved for release in the US, it must be assessed by the Animal and Plant Health Inspection Service (APHIS) agency within the US Department of Agriculture (USDA) and may also be assessed by the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA ...
On August 13, 2010, Judge White revoked the deregulation of glyphosate-resistant sugar beets and declared it unlawful for growers to plant glyphosate-resistant sugar beets in the spring of 2011. As a result of this ruling, growers were permitted to harvest and process their crop at the end of the 2010 growing season, yet a ban on new plantings ...
This reduction in pesticide use has been ecologically beneficial, but benefits may be reduced by overuse. [4] Yield gains and pesticide reductions are larger for insect-resistant crops than for herbicide-tolerant crops. [5] Yield and profit gains are higher in developing countries than in developed countries. [3]
Current Roundup Ready crops include soy, corn (maize), canola, [2] sugar beets, [3] cotton, and alfalfa, [4] with wheat [5] still under development. Additional information on Roundup Ready crops is available on the GM Crops List. [6] As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. [7] [8]
The U.S. Environmental Protection Agency, however, has a much higher tolerance for glysphosate in crops, allowing levels ranging from 0.1 to 310 parts per million. ... Glyphosate is most used as a ...
The use of herbicides presents a strong selection pressure on treated weeds to gain resistance to the herbicide. Widespread planting of GM crops resistant to glyphosate has led to the use of glyphosate to control weeds and many weed species, such as Palmer amaranth, acquiring resistance to the herbicide.
