My research and extension activities focus on weed management systems in irrigated dry bean and sugar beet cropping systems. This includes developing economical and environmentally safe weed management in narrow row dry bean production as well as reduced and no tillage dry bean and sugar beet production systems.

Ph.D., University of Idaho, 1986
M.S., University of Idaho, 1982
B.S., Utah State University, 1976

  • Effect of dry bean population grown in narrow-rows
  • Benefits of cover crop for weed control in dry bean
  • Potential hormetic effect of non-registered herbicides on sugar beet
  • Effect of tillage on weed control, sugar beet yield and quality

Don is a professor of weed science, UI Extension specialist and superintendent of the University of Idaho Kimberly Research and Extension Center. His research and extension responsibilities focus on integrated weed management in sugar beet, dry bean and small grain cropping systems. He also is involved in non-crop and horticultural weed management training.

Don is an Idaho native; born and raised on a farm near Idaho Falls. He received his bachelor’s from Utah State University and advanced degrees in weed science from the University of Idaho. He began his career in weed science at Kansas State University in 1986 and returned to Idaho in 1990 to join the staff at the University of Idaho Kimberly Research and Extension Center.
