On this weekend’s show, host Shaun Haney is joined by: Charles Geddes with Agriculture and Agri Food Canada on the Kochia Survey Results; Jon Driedger of LeftField Commodity Research on the markets; A clip from our recent Canola School with Keith Gabert of… Read More

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

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

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
