If you’ve noticed more than a few fleabane “escapes” in recent years, you’re not alone. Glyphosate resistant Canada fleabane has spread across more than 700 kilometers of Ontario crop land in just five years. Despite its incredible distribution, Canada fleabane wasn’t the first glyphosate resistant weed found in Ontario, says Dr. Peter Sikkema, field crop… Read More

It’s our own complacency that brought on the threat of antimicrobial resistance, says Trisha Dowling, a professor of veterinary clinical pharmacology at the Western College of Veterinary Medicine. “We got complacent just pretty much thinking there was a pill for every ill. So there’s been a whole lot of use of antibiotics just in case someone or… Read More

Wheat School - Spotting Herbicide Resistant Wild Oats

Herbicide resistant wild oats are pretty easy to identify, says Neil Harker, a research scientist in weed ecology and crop management at Agriculture and Agri-Food Canada’s Lacombe Research Centre. “You generally see them in patches. If you see [wild oats] in real straight lines, then you suspect a sprayer error, but if you just see them in… Read More

Can deep-tilling soybean residue be justified? A researcher from the University of Manitoba is looking at whether tillage practices need to change as farmers in Western Canada grow more soybeans. Despite leaving less plant matter behind than most crops, it’s not uncommon to see soybean ground cultivated to leave a dark surface that warms up and dries out… Read More

The advent of glyphosate resistant weeds has and will continue to complicate pre-plant weed removal. Farmers need to match herbicide resistance management and control options with targeted weed species to ensure not only an effective kill, but also to avoid limiting control options later. Glyphosate-resistant giant ragweed has been confirmed in Ontario, and farmers set… Read More

Responsible, appropriate use of antimicrobial products is a cornerstone of managing resistance to these products in both humans and livestock. For many outside the livestock industry, a lack of understanding about the use of these products, their administration and withdrawal times has created misconceptions and undue concern over the risk of antimicrobial resistance in beef… Read More

Developing a full understanding of antimicrobial resistance is imperative to managing its occurrence. Canada’s beef industry has been studying the incidence of antimicrobial resistance in cattle for some time, but there is more work to be done. Building off this introduction on antimicrobial resistance by Dr. Reynold Bergen, this episode of the Beef Research School… Read More
