Judit Barroso grew up in Madrid, Spain, but spent her summers in a small town where her family owns some land in the rolling Spanish countryside. She is an Agronomist Engineer by the Polytechnic University of Madrid with a PhD in Weed Science. Her doctoral thesis titled “Site-specific management of wild oat populations present in cereal crops in central Spain” received the extraordinary award of doctorate in 2006. Her interests in precision agriculture brought her to Montana State University in 2010 where she worked with several growers to optimize herbicide treatments in cereal crops. At the end of 2014, she moved to CBARC-OSU, where she continued studies on site-specific weed management but initiated other research lines as well. She is the past chair of the research program for the Western Society of Weed Science (WSWS) and has been the eastside director of the Oregon Society of Weed Science (OSWS) for several years.
Research:
Dr. Barroso’s program focus on weed management issues of critical importance in dryland cropping systems, with the intent to foster adoption of best practices leading to effective weed control, while preserving the environment and maintaining or improving crop yields.
Current main research lines:
- Integrated and cooperative Russian thistle management.
- Effect of cover crops and alternative crops on weed dynamics.
- Efficacy of harvest weed seed control in the PNW.
- Herbicide resistance in grass weeds and solutions (IWM, CoAXium wheat, occasional tillage).
- Collaboration with the industry to improve chemical weed control.
