Background and Interests

William McCloskey received a Ph.D. in Plant Physiology specializing in Weed Science from the University of California, Davis. He also has a Master of Science Degree in Plant Physiology from UCD and a Bachelor of Science degree in Plant Science which he received from the University of California, Riverside. Dr. McCloskey teaches Weed Science at the University of Arizona to students on campus and to off-campus Extension audiences. His research interests include: (1) evaluating new herbicides and transgenic crop systems for efficacy in controlling weeds in Arizona crops; (2) developing new uses for registered herbicides; (3) developing alternative means of weed management using precision guidance technology (GPS), optical sensing, computerized application technology, mechanical cultivation, crop rotation, and cover crops; (4) evaluating conservation tillage production systems and weed management without tillage in irrigated desert production systems, and (5) study of the effects and physiological mechanisms of weed competition in Arizona crop production systems including the interactions between weed species density, water availability, and light on crop yield, growth, leaf water potential, and photosynthesis.
