Jointed goatgrass is a weed that competes with wheat, resulting in reduced yield and increased grain dockage. Managing jointed goatgrass in winter wheat requires a systems approach that integrates multiple control tactics, described in this bulletin. Although jointed goatgrass is a major problem in most winter wheat growing areas west of the Mississippi River, the climate and cropping patterns of the Pacific Northwest (PNW) are unique and may influence the choice of options available for effective management of this pest. In particular, producers have noted that by adopting direct seed/reduced tillage management systems, both the number of jointed goatgrass infestations and the densities of these infestations tend to increase.
