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]
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.
The majority of GM crops have been modified to be resistant to selected herbicides, usually a glyphosate or glufosinate based one. Genetically modified crops engineered to resist herbicides are now more available than conventionally bred resistant varieties; [20] in the USA 93% of soybeans and most of the GM maize grown is glyphosate tolerant. [21]
Glyphosate is a broad-spectrum herbicide, which is used to kill weeds and grasses which are known to compete with commercial crops grown around the world. The first product came onto the market in the 1970's under the name ‘Roundup’. Plants which are exposed to glyphosate are unable to produce aromatic amino acids and in turn die. [1]
As of 2018, the commercialised crops are limited mostly to cash crops like cotton, soybean, maize/corn and canola and the vast majority of the introduced traits provide either herbicide tolerance or insect resistance. [91] The majority of GM crops have been modified to be resistant to selected herbicides, usually a glyphosate or glufosinate ...
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 most prevalent GM trait is herbicide tolerance, [141] where glyphosate-tolerance is the most common. [142] Glyphosate (the active ingredient in Roundup and other herbicide products) kills plants by interfering with the shikimate pathway in plants, which is essential for the synthesis of the aromatic amino acids phenylalanine , tyrosine ...
