Rate My Professor Judit Barroso

Judit Barroso is an Associate Professor in Weed Science in the Department of Crop and Soil Science within Oregon State University’s College of Agricultural Sciences. She is based at the Columbia Basin Agricultural Research Center in Adams, Oregon, where she develops and leads research and outreach programs integrating chemical, cultural, and mechanical weed control measures. These efforts employ novel approaches to address weed management in wheat-based production systems of eastern Oregon, particularly in dryland and fallow-based cropping systems. Barroso earned her B.S. in Agricultural Engineering and Ph.D. in Weed Ecology from the Polytechnic University of Madrid. Her doctoral thesis, “Site-specific management of wild oat populations present in cereal crops in central Spain,” received the extraordinary award of doctorate in 2006. Before joining Oregon State University at the end of 2014, she collaborated with growers at Montana State University in 2010 to optimize herbicide treatments in cereal crops.

Barroso’s research specializes in the effects of cover crops on weed infestations, efficacy of harvest weed seed control in Pacific Northwest wheat systems, control of herbicide-resistant weeds through strategic tillage, herbicide resistance mechanisms, and industry collaborations for enhanced chemical weed control. Her recent peer-reviewed publications include “Cover cropping in dryland wheat systems of the U.S. Pacific Northwest: Biomass production, weed suppression, and soil water” (Agronomy Journal, 2025, in-press), “Russian thistle (Salsola tragus) ecology in wheat cropping systems of the Pacific Northwest” (Weed Science, 2024), “EPSPS gene amplification in a glyphosate-resistant population of Italian ryegrass (Lolium multiflorum) from Oregon” (Pest Management Science, 2024), “Herbicide resistance in Bromus spp.: a global review” (Weed Science, 2023), and “A hydrothermal model to predict Russian thistle (Salsola tragus) seedling emergence in the dryland of the Pacific Northwest (USA)” (Weed Science, 2024). She has also produced key extension publications such as “Integrated Management of Feral Rye in Winter Wheat” (PNW 660, 2025, in-press), “Italian Ryegrass Management in Inland Pacific Northwest Dryland Cropping Systems” (PNW 778, 2024), “Harvest Weed Seed Control: Applications for PNW Wheat Production Systems” (PNW 730, 2024), and “Russian Thistle: Management in a Wheat-Fallow Crop Rotation” (PNW 492, updated 2023). Through these contributions, Barroso supports wheat growers in managing resistant weeds like glyphosate-resistant Russian thistle, promoting sustainable practices that preserve environmental health and crop productivity.
