What kills roundup alfalfa in soybeans?

Roundup alfalfa, which is genetically modified to be resistant to glyphosate, can be controlled in soybean fields through the application of non-selective herbicides that contain glyphosate. However, other herbicides that target broadleaf plants, such as 2,4-D or dicamba, can effectively kill Roundup alfalfa without harming soybeans, especially when used at the appropriate growth stages. Additionally, cultural practices like crop rotation and mechanical methods can also help manage Roundup alfalfa populations in soybean fields.
