Based on the timeline of global adoption of glufosinate ammonium-resistant soybean crops, it can be observed that Dow Chemical Company was the first to introduce a brand of soybeans resistant to glyphosate, glufosinate, and 2,4-D herbicides. The company received regulatory approval for food use in countries such as Australia, Canada, South Africa, and the United States in 2011. Subsequently, approvals for food and feed use were obtained in Japan, Mexico, and China (Taiwan) in 2014, and in Argentina and Brazil in 2015. In 2016, Colombia joined the list, followed by the European Union and Malaysia in 2017, China in 2018, and the Philippines in 2019 (Dow Chemical Company, 2013-2019). Similarly, the Enlist™ Soybean brand was introduced in Australia and the United States in 2011, followed by approvals in Canada, Mexico, China (Taiwan), Japan, and South Korea (Enlist™ Soybean, 2011-2019). Moreover, the Conkesta Enlist E3™ Soybean brand entered the markets of Argentina, Colombia, Mexico, and China (Taiwan) in 2016, and subsequently obtained approvals in Brazil, Japan, and South Korea (Conkesta Enlist E3™ Soybean, 2016-2017). Bayer Crop Science's Liberty Link® GT27™ soybean, resistant to glyphosate, glufosinate, and isoxaflutole, received approvals in Brazil and Mexico in 2015, followed by Colombia, Japan, South Korea, China (Taiwan), and the European Union (Liberty Link® GT27™, 2015-2018).

The comparison of the global introduction and regulatory approval of glufosinate ammonium-resistant soybean crops in different countries highlights the progress made by Dow Chemical Company, Enlist™ Soybean, Conkesta Enlist E3™ Soybean, and Bayer Crop Science brands. These brands have provided an effective solution to combat glyphosate resistance in soybean crops, receiving recognition and support from regulatory authorities for food, feed, and cultivation purposes in various countries. This has offered farmers more options to improve crop yield and quality while reducing weed control costs. Furthermore, it contributes positively to environmental protection and the development of sustainable agriculture.
