Soybean Traits for Weed Management


Of the 32 weed species resistant to glyphosate, only 7 account for about 99% of economic losses. According to Ian Heap, director of the International Survey of Herbicide-Resistant Weeds, these weeds include Palmer amaranth, marestail or horseweed, and tall waterhemp.

Advanced genetics contain more options for managing weeds, and there are a number of Golden Harvest soybeans that offer Roundup Ready 2 Yield®, Roundup Ready 2 Xtend® and LibertyLink® traits.

To help determine which traits are best for your farm, consider the weed pressure in your fields and your approach to managing weeds. If your weed pressure is manageable with pre- and post-emergence residual herbicides, the Roundup Ready 2 Yield system maybe be the appropriate fit 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 and strong agronomic characteristics. 

In situations with tough-to-control weeds even when using pre- and post-emergence residual herbicides, Roundup Ready 2 Xtend and LibertyLink varieties offer different modes of action that may be a better choice. With Roundup Ready 2 Xtend soybeans, you can incorporate approved dicamba formulations into your weed management program.
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.

Having additional herbicide tolerance tools in your toolbox offers improved control over resistant and other tough-to-control weeds.
