Nicholas E. Korres

received his MSc in Crop Physiology and his PhD in Weed Science from the University of Reading and his post-graduate degree in Operational Research and Applied Statistics from the University of Salford. His current research, at the University of Arkansas-Fayetteville, USA, involves, amongst other, weed demographics and population dynamics within crops, cropping systems or diverse environments, weed eco-physiology, weed-crop interactions and integrated weed management. He has published widely in weed science, agronomy, abiotic stress and climate change effects on crops and weeds and bioenergy production.

Nilda R. Burgos

is a Professor of Weed Physiology at the University of Arkansas-Fayetteville, USA. She studies herbicide-resistance; fitness consequences of herbicide resistance; abiotic stress tolerance in crops and weeds; allelopathy and herbicides for weed management; interaction of growth regulators and herbicides; adjuvants; and gene flow between rice and weedy rice. She teaches graduate courses on Ecology and Morphology of Weedy and Invasive Plants and Physiology of Plant and Herbicide Interaction. She also team-teaches Weed Science Practicum and Advanced Crop Science. She is President of the International Weed Science Society for 2016-2020.

Stephen O. Duke

received his PhD in botany from Duke University in 1975. He is a plant physiologist with the Agricultural Research Service of the USDA. Best known for his research on herbicide modes of action and natural products for weed management, he has over 400 peer-reviewed publications and has been editor or co-editor of ten books and co-author a textbook on mode of action of herbicides. He is Editor-in-Chief of Pest Management Science, and has been president or chair of several scientific societies, including the Weed Science Society of America and the International Weed Science Society.
