Webinar: Containment/Restoration of Annual-Brome Invaded Mixedgrass Prairie Using the Herbicide Indaziflam

- Anabel Dombro - University of Alberta

Annual bromegrasses are prevalent weeds on North American rangeland that are spreading
into Canada’s mixedgrass prairie. They change plant community structure and function, lower
desirable and overall forage production, negatively affect mammal and bird habitat, and cause
frequent fires. Control of these invasive species is of interest to land managers when looking to
improve or maintain rangeland function.
Field trials at two locations in the dry mixedgrass prairie of SE Alberta compared the effects of
four rates of indaziflam (0, 40, 80 or 160 g ai ha-1) applied at two times (fall or spring) on
annual-brome invaded native grassland. Biomass responses of brome and other vegetation
were assessed over 3 years. The project also looked at the effects of indaziflam on non-target
native species with a field study and two greenhouse studies, which looked at how indaziflam
impacted native perennial grass root growth and the native perennial seed bank.
