When spraying post-emerge herbicides in conventional soybeans, getting good coverage is key to controlling weeds such as ragweed and pigweed. On this episode of RealAgriculture Soybean School, Syngenta Canada agronomic sales representative Brad Garlough explores how new sprayer technology can help growers get better herbicide coverage, optimize weed control, and defend the farm against herbicide… Read More

Common ragweed’s ability to resist the control efforts of different herbicide groups continues to grow across Ontario. Last winter, University of Guelph weed scientist Dr. Peter Sikkema confirmed the presence of Group 14 resistance in common ragweed, making the broadleaf pest resistant to enzyme inhibitors, including branded weed control products such as Reflex and Blazer,… Read More

As soybeans move through the early vegetative stages, it’s time for growers to tackle those broadleaf weeds and grasses that might have evaded soil-applied herbicides or emerged after burndown. On this episode of the RealAgriculture Soybean School, BASF agronomist Rob Miller and host Bernard Tobin talk strategy in a weedy field of 1st trifoliate soybeans… Read More

As edible bean planting wraps up across Ontario, grower focus shifts to controlling post-emergent weeds and grasses. When seed is planted to moisture, in warm soils, growers and agronomists will need to get out and scout to determine what competition, including small and actively growing weeds, the emerging crop will encounter. On this episode of… Read More

As planting of corn and soybeans nears the finish line across Ontario, farmers and agronomists are turning their attention to weed control. A stretch of dry weather that fuelled a two-week sprint of planting, with little time for spraying, means many growers are now checking the status of pre-plant applications and trying to determine next… Read More

A widespread rain sweeping across Ontario this past weekend provided plenty of moisture to activate soil-applied, pre-plant herbicides in crop fields throughout the province. With the timely rain, many growers are now asking: after activation do these herbicides have the capability to ‘reach back’ and control already-emerged weeds and grasses such as foxtail? University of… Read More

Nightshade can be a nightmare for edible bean growers. The weed can play havoc with the crop as mature berries produced by the eastern black nightshade plant cause edible bean staining and mud tagging, and can even gum up cleaning equipment at the processing plant. On this episode of the RealAgriculture Edible Bean School, Ontario… Read More

It is the year of the dandelion. The hardy perennial pests are bigger and more plentiful in fields across Ontario than farmers can ever remember. University of Guelph weed scientist Peter Sikkema has been fielding many questions about why the weed is so abundant this spring and how best to control it. When it comes… Read More

Ideally, we want to get every crop off to the best start possible. One of the ways that this can be done in canola is through a pre-emergent herbicide, says Marissa Robitaille Balog, of the Canola Council of Canada. “Canola isn’t super competitive when it’s small,” Robitaille explains in this Canola School episode. “It’s pretty… Read More

Glyphosate-resistant Canada fleabane was first confirmed in Ontario in 2010. Fast-forward thirteen years and the weed now has developed resistance to multiple herbicide groups and can be found in Essex County, bordering Michigan, all the way east to Glengarry County, adjacent to the Quebec border. University of Guelph weed scientist Dr. Peter Sikkema has been… Read More

Early season weed control, tank mix tips, troublesome weeds, and a whole lot more are the focus on this episode of The Agronomists. Host Lyndsey Smith is joined by Mike Cowbrough of the Ontario Ministry of Agriculture, Food, and Rural Affairs (OMAFRA), and Tammy Jones of Corteva Agriscience. This episode of the Agronomists is brought… 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
