The purpose of this publication is to provide information about jointed goatgrass and its control with an emphasis on prevention and management of herbicide resistance. To date, herbicide-resistant jointed goatgrass acquired through natural selection has not been confirmed in the field. However, herbicide-resistant hybrids between Clearfield® wheat and jointed goatgrass have been identified in commercial wheat fields. The usefulness of Clearfield® wheat for the control of jointed goatgrass with imazamox (Beyond®) can be sustained only as long as jointed goatgrass populations remain susceptible to the herbicide.
