Transgenic crops cotton

Glufosinate has a broad weed spectrum (little to no selectivity), and is therefore sometimes marketed along with genetically engineered glufosinate-resistant crops (cotton, canola, maize, and rice). While this raises some concern in some parts of the world, transgenic technology has been widely accepted in the western hemisphere. Nevertheless, neither... 

Although the benefits of transgenic crops to consumers are somewhat abstract, as the level of agrochemical residues on crops is already very low, the benefits to farmers include higher profitability as a result of reduced chemical input and reduced toxic exposure. For example, farmers in some nations experienced a 75% reduction in exposure to the toxic effects of agrochemicals when growing transgenic cotton (46). Reductions in chemical exposure are clearly beneficial to the farmer, farm workers, and wildlife. 

The use of genetically modified corn and cotton has increased over 10-fold from 1992 to 1999 and as of 2002, 50 crop species have been evaluated for uses by the US Food and Drug Administration (FDA). In the development of transgenic crops, genes isolated from several varieties of the bacterium. Bacillus thuringienses (Bt) are probably the best known and most often cited example of GMO development. 

Many of the new transgenic crops (36%) are crops engineered to be resistant to old herbicides.331 These include bromoxynil (11.65) (TD50 111 mg/kg oral, mice) for cotton, and glyphosate for maize, cotton, and soybeans.332... 

Possibly, the largest triumph of biotechnology is in the introduction of transgenic crops, an advance that has revolutionized crop production. The first commercial introduction of genetically modified organisms (GMO) occurred in 1996. By 2000, transgenic soybeans, corn, and cotton accounted for more than half the area planted to these crops (Bruening, 2000).
