Weed Management

Dr. Andrew Kniss, Assistant Professor, leads a research program focusing on sustainable weed management in agronomic crops, especially sugarbeet, winter wheat, corn, and dry beans. Recent research projects include:

  • long-term management of jointed goatgrass in imidazolinone-resistant (Clearfield) winter wheat
  • synergistic herbicide combinations for management of feral rye
  • new herbicide options in proso millet
  • effect of long-term glyphosate use in glyphosate-resistant (Roundup Ready) cropping systems,
  • use of ethofumesate in glyphosate-resistant (Roundup Ready) sugarbeet,
  • management of volunteer corn in dry beans and sugarbeet.

Dr. Brian Mealor, Assistant Professor and Extension Weed Specialist, leads an Extension, research and teaching program focused on: 1) investigating long-term impacts of non-native invasive weeds on native plant communities, 2) developing and improving management strategies to reduce the ecological and economic impacts of invasive weeds, and 3) understanding the inherent resilience of native populations to biological invasion. My work is done primarily in extensively-managed rangelands of the western United States.

Current Research

  • Ecological resilience and invasion
  • Restoration of weed-dominated rangelands
  • Weed management for energy reclamation
  • Rocky Mountain Cheatgrass Management Project
