Prior to 2009, all licenses used the US01 version code. In 2009 Syngenta launched a new agreement to incorporate the addition of Roundup Ready 2 Yield® soybeans and Agrisure Viptera®, requiring the launch of the US02 license version. Then in 2013 Syngenta launched the Agrisure Duracade® trait, which required another update to the Syngenta Seeds, LLC Stewardship Agreement and the launch of the US03 license version. Since 2013, the US03 agreement has been updated to include additional traits such as Roundup Ready 2 Xtend®, LibertyLink® and Enlist E3®. The current version of the agreement is still US03.
