The issue of herbicide resistance is a concern to all farmers. This is especially a concern in the areas where glyphosate tolerant crops are planted extensively. Prices over the past five years have made growing certain glyphosate tolerant crops very profitable. That profitability is causing some farmers to push their rotations which can impact in crop weed control and build resistance to glyphosate. Glyphosate resistance is a problem that is a bigger concern all the time in many areas of Canada and the United States. Glyphosate resistant giant ragweed has surfaced in parts of Ontario and group 1 resistant wild oats are a big problem in Manitoba.

We spoke with Dr. Hugh Beckie, a research scientist with Agriculture and Agri-Food Canada at the 2011 Farm Forum Event. We talked about the issue of resistance and asked him about his top concerns across parts of Canada with regards to resistant weeds.
