Herbicide resistance and mode of action basics [link]
Dr. Jeff Gunsolus describes what herbicide resistance is and how it can occur. Herbicide mode of action and mechanisms for developing resistance are also introduced. (University of Minnesota)
Herbicide mode of action breakdown [link]
This second video in the Herbicide Resistance Management series focuses on how herbicides work. For each group of herbicides, the affected biochemical reaction, translocation, time of herbicide application and symptoms are described. (University of Minnesota)
Herbicide resistance development by site of action [link]
This third video describes how resistance develops with continued use of the same herbicides, the importance of developing a robust resistance management program and the need to diversify herbicide sites of action. (University of Minnesota)
