Regulated Sugar Beet (Truvera® Triple-Stack Trait) Resistant to Glyphosate, Glufosinate, Dicamba Herbicides Being Evaluated in Several US Regions Including the Pacific Northwest
It is believed that human/weed interactions accelerated at the inception of agriculture! Prior to 1996, weed control in some crops was a major challenge. There was a running joke in the 80s and 90s...
Pacific Northwest Herbicide Resistance Initiative (PNWHRI) – Take the Problem Weeds Survey!
Good news everyone! Pacific Northwest land grant universities and three regional USDA-ARS units are launching a new Herbicide Resistance Initiative! Our goal is nothing short of creating a coordinated, interdisciplinary, systems-based approach to managing herbicide...
Wild carrot, or Queen Anne’s lace, is a widespread and difficult to control nuisance weed across most of western Oregon. It is prolific in roadsides, poorly managed pastures, post-harvest forestry sites, and other areas with...
