Dr. Aaron Hager contributes to increased crop production through development and implementation of integrated weed management programs. His research helps to identify and manage herbicide-resistance in the most aggressive agronomic weeds.

More information: The focus of Hager's research program is to develop innovative approaches that ultimately expand our knowledge and understanding of weed biology, with a particular emphasis directed toward addressing the contemporary weed species infesting the major field crops of Illinois. His ultimate research goal is to establish a robust applied research program, supplemented with basic research fostered through novel collaborations with molecular biology scientists and ecologists, to provide economical and sustainable solutions to the fundamental weed management challenges plaguing Illinois producers. A contemporary weed biology research program should be holistic and engender partnerships that establish new research paradigms to address the dynamic nature of weed management in Midwestern agronomic cropping systems. His extension/research appointment provides many opportunities to develop new research projects that address the immediate and long-term needs of producers. Forming research collaborations with current weed science faculty and staff provides opportunity for contemporary weed management challenges to be addressed using both applied research techniques and research techniques unique to the University of Illinois weed science program.

The silver bullet that wasn't: Glyphosate's declining weed control over 25 years

A new PNAS Nexus study led by scientists from the USDA Agricultural Research Service (USDA-ARS) and the University of Illinois Urbana-Champaign takes a retrospective look at glyphosate efficacy after tolerant crops were commercialized.

Tank-mixing herbicides may not be enough to avoid herbicide resistance

Eight years ago, University of Illinois and USDA-ARS scientists turned weed control on its head. More and more herbicide resistant weeds were popping up, and the pest plants were getting harder to kill. It was clear farmers could no longer rely on the same chemicals year after year. Industry campaigns and herbicide applicators began touting the benefits of rotating herbicides annually to avoid developing resistance, and rotation quickly became common practice.
