The primary goal of our lab is to provide a deeper understanding of herbicide efficacy and how to more efficiently utilize herbicides for weed management.  This research includes the discovery and management of herbicide-resistant weed biotypes, leveraging knowledge of herbicide physiology to optimize herbicide activity, and mitigating off-target movement of herbicides.  Currently, our lab is conducting a phenotypic and genetic analysis of waterhemp with resistance to multiple herbicide mode of action groups, along with developing practical management strategies,.  In addition, we have several graduate students working on improving the herbicide application process by understanding the factors resulting in off-target herbicide movement and using remote sensing as a tool to move further down the path of site-specific weed management.
