Thanks for tuning in to this Agronomic Monday edition of RealAg Radio! On today’s show, guest host Lyndsey Smith is joined by RealAgriculture’s resident agronomist Peter “Wheat Pete” Johnson to discuss a number of topics including: cool conditions and corn, tissue testing wheat, Group 14 resistant ragweed, and fall weed control results. We will then… 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
Thanks for tuning in to this Agronomic Monday edition of RealAg Radio! Host Shaun Haney is joined by Peter “Wheat Pete” Johnson to discuss all things agronomy from no ice on the Great Lakes, flea beetle pressure, spring planning, and more! We will also hear a discussion Kelvin Heppner had with Charles Geddes of Agriculture… Read More
Farmers in Western Canada should add another chemistry to the list to pay attention to when it comes to herbicide resistance in kochia, says a weed scientist with Agriculture and Agri-Food Canada. The problematic weed is already known to be resistant to Group 2, Group 4 and/or Group 9 herbicides. “The new thing that we’re… Read More
The advent of herbicide-resistant weeds was bad enough, but the expansion of type, area, and mode-of-action resistance has left nearly no field untouched across the all regions of Canada. What can we do and how did we get here? To tackle that question, host Lyndsey Smith is joined by Dr. Charles Geddes, Agriculture and Agri-Food Canada… Read More
A North Dakota State University (NDSU) study suggests that some kochia populations in western North Dakota likely have developed resistance to commonly used pre-plant burndown herbicides. Sold under the trade names Aim (carfentrazone) and Sharpen (saflufenacil), Group 14 herbicides are used by farmers to control kochia and other annual weeds. In the NDSU study, a… Read More
This past summer, a diligent agronomist in southern Alberta was suspicious of downy brome that was not being controlled by glyphosate. The population in question was widespread in a glyphosate-tolerant canola field in Taber County, Alberta, and was not controlled following multiple applications of glyphosate, says Charles Geddes, weed scientist at Agriculture and Agri-Food Canada,… Read More
Thanks for tuning in to this Agronomic Monday edition of RealAg Radio. On today’s show you’ll hear: Craig Drury, soil management and soil biochemist with Agriculture and Agri-Food Canada (AAFC) at Harrow, Ont., on what happens when soybeans are too tight in the rotation; Dr. Alan Blaylock, senior agronomist with Nutrien, with an eKonomics product… Read More
Kochia is one of the first weeds to emerge in spring. There are reports that 80 per cent of the kochia population emerges before anything else in a field. The fact that it emerges so early puts a lot of pressure on the pre-emergent herbicide options out there. In this Wheat School episode, Kara Oosterhuis… Read More
…And just like that, it’s Monday again! On RealAg Radio, that means one thing: it’s time to talk all things agronomy! On this Agronomic Monday episode, you’ll hear: The top ag news stories of the day with host Shaun Haney; Eric Persson of Syngenta Canada on all things soybean seed treatments; Alana Serhan of PRIDE… Read More
Starting the year off on the right foot requires a little bit of forethought and planning. When it comes to keeping a canola crop clean during the early stages of growth, there are some steps to take before even seeding the crop. Dr. Charles Geddes, research scientist in weed ecology and cropping systems at Agriculture… Read More
Weed surveys conducted in the Canadian Prairies since the early 2000s have tracked the incidence of herbicide resistance over time, and it’s not looking good. “In general, what we’re seeing is herbicide resistance is increasing on the Prairies,” says Charles Geddes, research scientist, Agriculture and Agri-Food Canada. “Currently, we’re sitting at — in Saskatchewan —… Read More
