Ben Westrich is a PhD student under Dr. Bryan Young. He is originally from Southern Illinois and received his BS in Plant and Soil Science and Agribusiness Economics from Southern Illinois University Carbondale. His research at Purdue University focuses on the evaluation of various herbicide programs that may be used in soybean varieties resistant to HPPD-inhibiting herbicides, with particular emphasis on controlling populations of giant ragweed (Ambrosia trifida) which are resistant to acetolactate synthesis-inhibiting (ALS) herbicides. His work also aims to quantify the resulting selection pressure for ALS-resistant giant ragweed biotypes from applications of ALS-inhibitors. Additionally, he is taking a closer look into the inheritance of herbicide resistance traits in giant ragweed as it relates to self-incompatibility and population diversity.
Expected graduation: May 2022.
