Identification and Control of Invasive and Troublesome Weeds in North Dakota(W1411, Revised May 2023)
This publication was made possible by collaboration of the author, North Dakota State University Extension and the North Dakota Department of Agriculture, with funding from the U.S. Forest Service for printing. This publication is intended to help land managers properly identify and control noxious and invasive weeds found in the state. The current list of 13 noxious weeds are included, as well as species listed by various counties as noxious. Other species included are either invasive weeds found in bordering states with the potential to move into North Dakota or are commonly misidentified native species that do not require control efforts, such as the native thistles. Control recommendations are current at publication, but options change rapidly. Before beginning any management program, please consult with your local county Extension agent and/or weed officer for the latest chemical, cultural and biological control recommendations. Chemical control recommendations are updated annually and printed in the “North Dakota Weed Control Guide,” Extension publication W253, and are updated more frequently on the Web at https://www.ndsu.edu/agriculture/ag-hub/ag-topics/cropproduction/diseas…. For the latest in biological control options, contact the North Dakota Department of Agriculture and/or the local staff of the U.S Department of Agriculture –Animal and Plant Health Inspection Service in Bismarck.
