Palmer amaranth (Amaranthus palmeri) is known by some as “careless weed,” as negligent management quickens its already hasty invasiveness. It can also be incredibly difficult to control — a characteristic that has only worsened in the last few years, as its resistance to multiple-herbicide groups continues to evolve. According to The International Survey of Herbicide… Read More

The vast majority of canola varieties grown on the Prairies are tolerant to some form of herbicide. Which makes sense, of course, as farmers immediately saw benefits to the technology and adopted the varieties en masse. But, like most things, there are trade-offs to the benefits of herbicide tolerance (HT). One of those is weed… Read More
The in-crop spraying season is just around the corner for a number of growers in Western Canada. Spraying at the proper time allows your crop to use nutrients and moisture without having to compete against various weeds, as well as allows your crop to metabolize herbicides more readily. What I want to focus on now… Read More
The issue of herbicide resistance is something producers will have to continue to be vigilant about. Careful consideration needs to go into the “when” “how” and “what” to use of your individual weed control strategy. That strategy in turn needs to be balanced with a good sense of corporate responsibility about producer issues like herbicide… Read More
The issue of herbicide resistance is a concern to all farmers. This is especially a concern in the areas where glyphosate tolerant crops are planted extensively. Prices over the past five years have made growing certain glyphosate tolerant crops very profitable. That profitability is causing some farmers to push their rotations which can impact in… Read More
The issue of herbicide resistance is a problem not fully realized, but it will get bigger, its just a matter of when. The amount of glyphosate and other similar products in use on tolerant crops right now coupled with the profitability of those crops means rotations will be pushed, giving more weeds exposed a greater… Read More
Weeds continue to develop resistance to herbicides, and Canadian farmers have been asking for new solutions. With the Enlist™ weed control system from Corteva Agriscience, you finally have more ways to overcome your weed issues. You can use herbicides that feature multiple modes of action to manage hard-to-control and resistant weeds. Enlist E3™ soybeans are tolerant to… 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
Federal Agriculture Minister Lawrence MacAulay announced a federal investment of over $4 million in Saskatoon on Tuesday for agronomy research through the Western Grains Research Foundation (WGRF). It will be matched with more than $1.9 million from WGRF itself, and $1.5 million from grower groups and industry partners, bringing total funding for the second iteration… Read More
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
Canola is not a very competitive crop in its early stages, so keeping an eye on the competition is key. We’ve covered on the Canola School why a pre-emerge herbicide pass can be valuable, but of course, the next step is to watch for weeds that have emerged with the crop. Sean McKnight, technical service… 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 you know: you plan to add another mode of action or two to your spring glyphosate application, because you know that’s a big step toward protecting your future glyphosate use. What you’re wondering: should you be adding a familiar and heavily used mode of action, or one that’s a bit off the beaten path?… 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
Before the age of combines, chaff was collected with a crop and left in a pile beside a threshing machine where it was then used for feed. A company based at Wawanesa, Manitoba is helping livestock producers return to this practice of collecting and feeding chaff by building a high capacity Australian-designed chaff cart that… Read More
