Micheal D.K. Owen is a University Professor and Associate Chair in the Agronomy Department and a Weed Management Extension Specialist at Iowa State University.  He received a PhD from the University of Illinois and has been at Iowa State University since 1982.  Owen is an adjunct professor at Escuela Agricola Panamericana in Zamorano, Honduras and at Michigan Technological University in Houghton, MI.  He also taught a PhD program in sustainable tropical agriculture at the University of Costa Rica.  Owen has directed more than 50 graduate students including 17 Ph.D. candidates and authored more than 100 peer-reviewed journal papers.  Owen was a co-author of the National Research Council report “The Impact of Genetically Engineered Crops on Farm Sustainability in the United States” released in 2010.  He has participated in research of herbicide-resistant weeds, resistance genetics and the ecological and economic implications of herbicide-resistant weeds.  Owen also investigates the social and economic aspects of farmer decisions concerning IPM and the management of herbicide-resistant weeds.

Presentation title

Sustainable weed management, what is next after glyphosate?

ABSTRACT - There is a critical need to adopt diverse tactics beyond herbicides, to manage weeds and mitigate herbicide-resistant weeds evolution.  Herbicides have been the primary approach to weed management for decades and the burgeoning issues of evolved herbicide resistances in key weeds reflects agricultural systems where herbicides have been the principle control tactic.  The inclusion of alternate strategies for weed control has declined steadily and the loss of weed management diversity resulted in evolved resistance to a number of herbicides.  Herbicide resistance and weed management issues exist not only in the USA but also throughout the world. Glyphosate was used in a majority of the row crop acres in the USA.     There are many reasons and justifications for this including time management efficiency, cost, effectiveness, and the simplicity and convenience of weed control.  The ecologically narrow focus of this approach has resulted in widespread evolved resistance to glyphosate to the extent that it should be clear that weed management in row crops is not sustainable if based primarily on a single herbicide.  However, herbicides will continue to play a significant role in the weed management.  Cultural and biological tactics will be important components of successful weed management programs in the future.
