Australian Herbicide Resistance Initiative (AHRI)

Weed control systems in herbicide resistant canola – a resistance reprieve?

Dr Neil Harker, Agriculture and Agri-Food Canada

Adoption of herbicide resistant (HR) canola in Canada is almost universal. But are Canadian farmers making use of the resistance management possibilities it offers? With three different systems, HR canola opens several in-crop spray options which aren’t available in alternative crops. Neil Harker says “Our (herbicide resistant) canola has given us a resistance reprieve but if we abuse it and overuse it, it won’t last long.”
