A Birdseye View of Robotic Weeding Technology

This episode, an interview with Sarah Stewart, and a shorter segment from an interview with Jichul Bae. 

The last few years, farmer and videographer Sarah Stewart has been working with Organic BC on some extension work that has involved a pretty big focus on emerging technologies for mechanical weed management. She’s learned a tonne about autonomous weeding robots and the use of lasers and electricity, and the increasing role that artificial intelligence is playing in the age-old battle to keep the weeds at bay. But gathering information was only half the job. The other half was to share it. Among other things, Sarah has produced videos about her findings and hosted equipment demonstrations around BC and coordinated conference panels and, behind the scenes, helped me produce the episodes about weeding agritech that you may have already listened to on this podcast.

I asked Sarah for an interview because it recently struck me how well-positioned she is to talk about the strengths and limitations of the newest generation of weeding agri-tech. What you’ll hear is that she’s bullish on the role she expects these tools will play on BC farms over the long term, but perhaps not right away. Listen to hear why!

Then: a segment of my conversation with Dr. Jichul Bae, a researcher at Agriculture and Agrifood Canada based at the Agassiz Research and Development Centre. Jichul focuses on weed management and is an expert on herbicide resistant weeds. I had requested an interview with Jichul to talk about the strengths and limitations of weeding agritech. We ended up having a wide-ranging conversation. I’ll only be sharing a piece of it here, in which we talk about how good weeds are at adapting to our weed management strategies, especially when we rely too much on one form of management, regardless of the form in question. I’m including this segment here because, in the midst of all the hype around the promise of the newest generation of mechanical weeding technology, Jichul wants us to consider that no single approach should be thought of as a panacea.
