Jointed goatgrass is an annual invasive grass weed that infests winter wheat fields in the western United States, resulting in reduced wheat yield and quality.

Pigweed is an invasive plant pest usually found in disturbed areas, like farmland and along roadsides and fencelines. Because their aggressiveness can reduce crop yields, this PNW discusses how to prevent or curtail their spread in the region by learning how to identify them, their impacts, and the most effective control options (sanitation, mechanical, cultural, and herbicidal methods).
