The issue of herbicide resistance is something producers will have to continue to be vigilant about. Careful consideration needs to go into the “when” “how” and “what” to use of your individual weed control strategy. That strategy in turn needs to be balanced with a good sense of corporate responsibility about producer issues like herbicide resistance. As time goes on it’s only natural that we should see more weed species develop resistance to some of the more widely used herbicides but there are practices producers can employ to slow that process.
The discovery of glyphosate resistance in a number of different weed species is a prime example of some of the dangers surrounding the over use of herbicides and the necessity of multiple modes of action in weed control strategies. Chem fallow is one of those strategies that should be adapted with herbicide resistance in mind.

In this episode of the Canola School, we visit the CanoLAB 3D event that took place in early March and talk to Eric Johnson of Agriculture & Agri-Food Canada about the issue of chem fallow and herbicide resistance.
