With herbicide resistance on the rise, the need for more tools in the toolbox is higher than it has ever been, because as Dr. Breanne Tidemann of Agriculture and Agri-Food Canada says, there are no magic bullets. While any single management strategy is unlikely to be the final solution to herbicide resistance and weeds generally,… Read More

Many farmers are excited to not have to worry about soil moisture this growing season, as recent drought conditions have broken for many areas of the Prairies. While rain truly is a good thing, it is also one of the things that is likely to trigger fungal diseases, such as fusarium head blight (FHB). Frequent… Read More
Resistance to glyphosate has not officially been confirmed in Canada fleabane populations in Western Canada, but the weed, sometimes called horseweed or marestail, should be on the radar when it comes to herbicide resistance on the Prairies, according to Manitoba Agriculture’s weed specialist. Canada fleabane that’s resistant to glyphosate and other chemistries is already established… Read More
Ground beetles are some of the most abundant natural enemies for crop insect pests, but their free services in the field often remain overlooked and under-appreciated, says an entomology professor from the University of Manitoba. “They’re far more abundant than most people realize, but many of our species are really restricted to the ground and… Read More
True armyworms hungry for grassy plants, including wheat, have arrived in large numbers in parts of the Prairies this summer. The pest, which migrates north as a light brown moth, arrived in Manitoba during the last week of May, explains John Gavloski, entomologist with Manitoba Agriculture, in this armyworm-focused Wheat School episode filmed at the… Read More
What’s old is new again, or at least as relevant as ever when it comes to managing herbicide resistant weeds. Research led by Charles Geddes, weed scientist with Agriculture and Agri-Food Canada at Lethbridge, shows cultural practices — tighter row spacing, higher seeding rates, and longer crop rotations — can be just as effective as… Read More
Winter is a great time to recalibrate your approach to managing wheat diseases and applying fungicides. That’s the message Penn State University plant pathologist Alyssa Collins shared with agronomists attending the Ontario Certified Crop Advisors annual meeting earlier this month. It’s a dormant period for humans and also for fungi and plants, says Collins. “So… Read More
What happens when you precision plant wheat? There’s a growing body of evidence indicating that better seed singulation, metering and depth control has the potential to improve uniformity of emergence, growth and crop canopy. That precise approach can also add up to higher yield potential and more grain in the bin. But many growers have… Read More
Work continues on training computer algorithms to unlock the potential of green-on-green spot spraying systems to identify and target the weeds found on Canadian farm fields. The goal of green-on-green spraying systems is to detect and apply herbicide to weeds that are growing within a green crop. Where green-on-brown spot spraying systems used for burnoff… Read More
From a crop nutrition perspective, nitrogen losses as N2O or nitrous oxide pale in comparison to what’s lost in N2 form, but N2O has a much greater impact on the total greenhouse gas emissions from fertilizer. As part of this Wheat School episode filmed at Manitoba Crop Diagnostic School, Manitoba Agriculture’s John Heard shares a… Read More
