Managing weeds when seeding cover crops - A new video highlights research at Michigan State University looking at the compatibility of different cover crop species with herbicides used in corn, soybean and wheat

Cover crops provide several benefits, including weed control, protecting soil from erosion and promoting soil health. When adopting this practice, farmers face several challenges, such as competition from weeds impacting the productivity of cover crops or even the cash crops themselves. For this reason, it is very important that weeds are controlled using herbicides, even when using cover crops.

To effectively control weeds when integrating cover crops into crop rotations, farmers need information on which chemicals can safely be used alongside the cover crop species they are using. Because cover crops are incompatible with certain herbicides, research is needed to make sure we do not control the cover crop along with the weeds.

In this new video, Michigan State University Extension specialist Christy Sprague addresses the question: When planting cover crops, which herbicides can I use?
