Jason Norsworthy has been awarded the prestigious Council of Australasian Weed Societies (CAWS) Orator at the Global Herbicide Resistance Conference to be held in Fremantle in February 2013.

Norsworthy is Professor and Elms Farming Chair of Weed Science in the Crop, Soil and Environmental Sciences Department at the University of Arkansas. He teaches Principles of Weed Control and team teaches Colloquium and Integrated Pest Management and has authored or co-authored over 110 refereed journal publications and over 400 abstracts. Studying the evolution and spread of herbicide resistance in southern United States cropping systems, specifically cotton, soybean, rice, and corn, his research has centered on developing strategies to manage resistant weeds and reduce the risk of herbicide resistance. He has documented seven new herbicide-resistant weeds in the region over the past six years.

Norsworthy’s research focuses on understanding the timing of viable weed seed production in an effort to better understand how management practices can be altered to prevent weed seed production, along with methods to target their destruction at harvest. Norsworthy recently led a team in preparing a position paper for the Weed Science Society of America outlining best management practices to mitigate the evolution of herbicide resistance.

Norsworthy’s contributions are measured not only in his productive and impressive writing record, but also in his recognition as an international and national authority and key influencer in the area of understanding and managing herbicide resistance. Norsworthy was the first to document clomazone resistance in barnyard grass, and ALS resistance in rice flatsedge and yellow nutsedge. 

Norsworthy’s presentation at the Global Herbicide Resistance Conference will focus on best management practices that mitigate the risks of herbicide resistant weeds evolving in cotton and soybean crops. Norsworthy will demonstrate that it is a diversity of management practices, which have been lacking in most U.S. cotton and soybean production systems, that is key to ensuring the long-term success of weed management programs.
