According to Neil Harker, research assistant with Agriculture and Agri-Food Canada, wild oat management through herbicide application costs western Canadian producers around $500 million annually. Herbicide resistance in many weed biotypes is cropping up — resistance within wild oat populations has been nagging at farmers’ fields for years and is spreading.
How can we combat this weed problem without continuing the downward spiral of herbicide resistance? “We’re going to have to diversify,” says Harker, and in this video, suggests a few different integrated weed management practices for wild oats, based on a current study being done at the Lacombe Research Centre. Diversify doesn’t mean just herbicide rotation, Harker explains that we need to think bigger and more long-term if we’re going to tackle the problem in a cost effective way, and farmers may even need to get comfortable with perennial crops again.
