When it comes to selecting soybean varieties, growers are faced with more choices than ever. Advanced genetics contain more options for managing weeds, and NK varieties offer Roundup Ready 2 Yield®, Roundup Ready 2 Xtend® and LibertyLink® traits.
To help determine which traits are the strongest fit for your fields, consider the weed pressure on your farm and your plan for managing weeds. If your weed pressure is manageable with pre- and post-emergence residual herbicides, the Roundup Ready 2 Yield system may be the best option because it provides a foundation for success to control challenging and late emerging weeds. Along with consistent weed management, Roundup Ready 2 Yield varieties offer proven genetics, strong agronomic characteristics and varietal placement knowledge.
In situations with difficult to control to control glyphosate-resistant weeds where pre- and post-emergence residual herbicides are lacking effectiveness, the Roundup Ready 2 Xtend and LibertyLink varieties offer different modes of action that may be a more effective weed management route. With Roundup Ready 2 Xtend soybeans, you can incorporate approved dicamba formulations into your weed control program. Roundup Ready 2 Xtend soybeans contain the Roundup Ready 2 Yield trait technology stacked with a trait that provides tolerance to dicamba.
The LibertyLink system is a unique market alternative to glyphosate-tolerant systems. It combines Liberty herbicide and the LibertyLink trait as the only nonselective soybean weed control. Liberty herbicide controls over 120 broadleaf weeds and grasses, including ALS- and glyphosate-resistant weeds. So far, there hasn’t been any documented weed resistance to Liberty.

Being equipped with additional herbicide tolerance modes of action offers improved control over resistant and other tough-to-control weeds.
