Kevin Bradley is an Associate Professor and State Extension Weed Scientist in the Division of Plant Sciences at the University of Missouri. He received a BS degree in Agriculture from Ferrum College and a PhD in Weed Science from Virginia Tech. His faculty appointment includes Extension and research responsibilities in the area of weed management in corn, soybean, wheat, pastures, and forages. In addition to evaluating new herbicides and weed management techniques, Dr. Bradley's applied research program focuses on the development of programs for the prevention and management of herbicide-resistant weeds, on the interaction of herbicides and weeds with other agrochemicals and pests in the agroecosystem, and on the effects of common pasture weeds on forage yield, quality, and grazing preference. By far the largest percentage of Dr. Bradley’s research and Extension efforts are directed toward the development of strategies for the management of glyphosate- and multiple herbicide-resistant weed biotypes. Specifically, he has conducted numerous surveys to characterize the prevalence of herbicide resistance in weeds such as waterhemp and to determine the effectiveness of cultural practices and future herbicide-tolerant crop technologies for the management of these troublesome species.
