Weeds to watch in 2026: Invasive pigweeds and more

It's worth being on guard for invasive pigweeds like Palmer amaranth and waterhemp this coming season. So far, these weeds haven't been discovered in Saskatchewan or Alberta, but they've been slowly creeping up from south of the border.

In this episode of Inputs, Kaitlin Berger, editor of Top Crop Manager West, speaks with Dr. Shaun Sharpe, research scientist at Agriculture and Agri-Food Canada. Tune in to hear about his project to raise awareness about these problematic weeds. Sharpe discusses the status of invasive pigweeds in Canada, why they pose a threat and how to mitigate it across the Prairies. He also dives into helpful management strategies for kochia and wild oat this season.
