Research Focus

The focus of this project is to improve weed management in soybean by characterizing
new and expanding types of herbicide-resistant weeds across the Indiana landscape and
working towards increased education and successful implementation of Roundup Ready
Xtend soybean to provide the greatest benefit to Indiana soybean producers.


  • Document the confirmation and distribution of Palmer amaranth, waterhemp, giant
    ragweed, horseweed, and other emerging weeds that are resistant to glyphosate, PPOinhibiting herbicides, and other key herbicide modes of action.
  • Demonstrate Best Management Practices for Roundup Ready Xtend soybeans for


The results will be added upon completion of the project.


Reduce the impact of herbicide-resistant weeds on soybean production and profitability and develop best management practices for herbicide-resistant weed species.
