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

- Anabel Dombro - University of Alberta

We have RESCHEDULED the GRF Winter Webinar II to March 22nd. There is no need to re-register to attend the new date of March 22nd. We were unable to proceed as scheduled due to an unexpected internet outage at U of A… so we are pleased to be hosting the webinar – Containment/Restoration of Annual-Brome Invaded Mixedgrass Prairie Using the Herbicide Indaziflam, presented by Anabel Dombro, University of Alberta on March 22nd, 2023 from 12:00 noon until 1:00pm.

What we will cover: 

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.

Join us Tuesday March 14 th between 12 and 1pm MST for the webinar. There is no charge, but
donations are gratefully accepted.
