Abstract
The commercial launch of glyphosate‐resistant soybeans in 1996 signaled the beginning of a new era in weed management in row crops. Today, over 80% of the soybeans grown in the USA are glyphosate resistant. Since that time, many crops have been transformed that have allowed crop applications of many classes of herbicide chemistries. Crops currently under production include maize, soybean, cotton and canola. Transformation technology and selection methods have improved and the rate of development as well as the breadth of crops being considered as commercial targets has increased. On the basis of recent adoption rates by growers around the world, it appears that glyphosate‐resistant crops will continue to grow in number and in hectares planted. However, global public acceptance of biotechnology‐derived products will continue to impact the rate of adoption of this and other new innovations derived from transformation technology.
