Personal Information:
Dr. Peter Dotray received his B.S degree from the University of Minnesota in Agronomy in 1986, his M.S. degree from Washington State University in Agronomy in 1989, and his Ph.D. degree from the University of Minnesota in Agronomy in 1993. He joined the Texas Tech faculty in 1993 and is currently an Associate Professor of Weed Science. He holds a joint appointment between Texas Tech University (52%), the Texas AgriLife Research (24%), and the Texas AgriLife Extension (24%). His responsibilities at Texas Tech include teaching Principles of Weed Science, Modes and Mechanisms of Herbicide Action, and Tech Transition: The Freshman Seminar. Dr. Dotray has completed 14 Master of Science students, three Ph.D. students and two on-thesis students. He currently advises or co-advises three M.S. students. At the Texas Agricultural Experiment, Dr. Dotray has an active research program examining weed control systems in cotton, peanuts, corn, and a variety of other crops. He also serves as the Extension Weed Specialist in District 2.

Research Interests:
My research interests include developing effective and economical weed management systems in cotton and peanut. The use of herbicide-resistant varieties has improved weed management strategies in cotton, but effective and long term success in weed control systems must involve herbicides with different modes of action, as well as other weed management strategies. The use of reduced tillage systems provides new challenges in weed management because of the difficulty of incorporating preplant herbicides.
