Staying on top of herbicide resistance
Welcome to part two of Top Crop Manager Focus On: Herbicide Resistance. This final edition of our summer digital series summarizes more of the fantastic research presented at the 2018 Herbicide Resistance Summit, held Feb. 27 and 28 in Saskatoon.
Now more than ever, herbicide resistance is a growing problem for field crop producers across Canada and around the world: in fact, between the beginning of June 2018 (when we released the first edition of Focus On: Herbicide Resistance) and the end of August 2018, nine cases of herbicide resistant weeds were entered into the International Survey of Herbicide Resistant Weeds database at www.weedscience.org. According to the database, there are currently 495 unique cases of herbicide resistance globally. Based on that data, and the information our esteemed Summit presenters shared, this is not a problem that will easily disappear.
In this special edition, you’ll read perspectives and strategies from five herbicide-resistance experts from across North America. Though specifics vary, one message is clear: the management of herbicide resistance requires ongoing stewardship and attention.
As you prepare to wrap up another growing season, we hope you find answers to your resistance-related and other agronomic questions among our pages.
