Applied Weed Science, Herbicide resistance, Weed Ecology and Management
Herbicide-resistant weeds pose a serious threat to agricultural productivity and global food security. The major goal of my research program is to understand the evolutionary biology of the weeds and develop integrated weed management (IWM) strategies that can protect water quality, and enhance crop productivity and economic returns. I take a collaborative research approach to address weed management challenges.
The goal of my Extension program is to provide leadership in the development of best management practices (BMPs) to reduce the risks of herbicide resistance evolution in weeds. My program is informed by stakeholders' needs and committed to providing timely, science-based education materials to the Minnesota growers, consultants, and agricultural industry partners.
