  • Graduate Research Assistant

Brent Mansfield is a M.S. student with Dr. Bryan Young studying the mechanism(s) for waterhemp resistance to PPO-inhibiting herbicides.  The research objectives are to: identify any alternative resistance mechanisms to PPO-inhibiting herbicides other than the confirmed ∆G210 codon deletion, assess the selection pressure for PPO-resistant biotypes from field use of soil residual PPO-inhibiting herbicides, and determine if differential metabolism of reactive oxygen species could contribute to waterhemp resistance to PPO-inhibiting herbicides.  The overall goal is to develop improved management strategies for PPO-resistant waterhemp, slow selection for PPO-R biotypes, and prolong the effective lifespan of PPO-inhibiting herbicides in order to lessen the detrimental impact of waterhemp on corn and soybean yields.
