About

The University of Idaho Weed Science Program conducts basic and applied research and statewide extension education on weed management in both crop and non-crop areas. Our weed science programs are dedicated to advancing basic and applied weed science research, while providing practical solutions for weed management in crop and non-crop areas. Our team combines scientific rigor with on-the-ground experience to address the growing challenges of invasive and competitive weed species. Our mission is to develop sustainable, environmentally responsible, and economically viable weed management strategies that benefit farmers, land managers, and the broader community. We work closely with stakeholders across agriculture, forestry, urban landscapes, and natural areas to tailor our research to real-world needs. Through our applied research and extension programs, we provide timely research-based information and recommendations to stakeholders in these main areas:

  • Best weed management practices in agronomic crops include but are not limited to alfalfa, corn, chickpea, dry bean, lentil, potato, peas, small grains, and sugar beet.
  • Invasive plant species biology and management in range and forest plant communities.
  • Report and document herbicide-resistant weeds in crop and non-crop areas through routine weed surveys.

We bridge the gap between research and applications by offering educational programs, resources, and personalized guidance.
