Research Focus

The focus of this project is to examine the benefit of cereal rye to provide prolonged weed control and reduce herbicide inputs.


  • Management of large Palmer amaranth; impact on yield and weed seed production.
  • Investigate utility of late-terminated cereal rye for reducing herbicide inputs for Palmer amaranth management.


Results will be updated upon completion of the project.


This research will benefit Delaware’s soybean growers and the soybean industry by knowing potential options when spraying large Palmer amaranth plants and expand the options of non-chemical strategies to help control plants with few to no herbicide options.
