Quite often, growers discover herbicide resistant weeds on their farm after an effective herbicide fails to take out a targeted weed. After some testing and reviewing past herbicide application records, growers might realize that the resistance problem is the result of repeated use of a particular herbicide or a history of not following best management… Read More

Resistance Management School focuses on the growing presence and impact of herbicide resistant weeds. From best management practices and strategies to reduce resistance to responsible management of crop protection technologies and traits, the Resistance Management School helps Canadian farmers win the war against herbicide resistant weeds. The Resistance Management School is made possible by support… Read More
What’s the best strategy for managing herbicide resistance on your farm? In this episode of RealAgriculture’s Resistance Management School we visit Günter Jochum at his farm near St. Francois Xavier, MB. In 2010, Jochum discovered Group 1 herbicide resistant wild oats in one of his fields. Once the presence of resistant wild oats was confirmed, Jochum adopted… Read More
Look through many soybean seed catalogues and you’ll find an ‘LL’ in the trait category surrounded by a plethora of ‘RR2Y’ and ‘RR2Xtend’ abbreviations, noting the last two versions of Roundup Ready seed technology. The number of Liberty Link (LL) herbicide system varieties are few compared to the massive Roundup Ready seed footprint, but the technology… Read More
If it’s early January and you’re in Saskatoon, it must be time for Crop Week! Live from the Nufarm booth at the Western Canada Crop Production Show (say that three times fast), you’ll hear all sorts of great agronomy tips in this special on-location episode of RealAg Radio. On this show, you’ll hear: The News… Read More
When you’re talking about weed control for field peas, chickpeas and soybeans, grower experience and a growing body of research have this to say: the earlier, the better. This is particularly true for field peas and chickpeas. With limited in-crop weed control options for these two crops, an effective pre-emergent application provides vital early-season weed… Read More
Can spray technology help us better manage the escalating problem of herbicide-resistant weeds? Spray guru Tom Wolf, from Saskatchewan-based Agrimetrix Research & Training, certainly thinks so. At the recent Canadian Weed Science Society meeting at Niagara Falls, Ont., Wolf highlighted two technologies he believes could help help growers manage weed resistance. In this video, Wolf and… Read More
There’s a new option for those having to deal with pesky weeds in Canada. The Pest Management Regulatory Agency (PMRA) has cleared the way for a new pre-seed/pre-emerge herbicide for use on lentils, field peas, soybeans, and corn. BASF’s new Heat Complete will be available for producers for next year’s crop season. The herbicide has both Group 14… Read More
Earlier this year, Dr. Peter Sikkema, professor with the University of Guelph and his research team confirmed Group 14 resistance in waterhemp at multiple locations in Ontario. Sikkema’s research team, including graduate student Lauren Benoit, has also confirmed waterhemp with cross-resistance to Groups 2, 5, and 9, as well as 14. In this episode of the Resistance Management… Read More
Highly competitive crops that make it difficult for weeds to gain a foothold in fields play a key role in effective herbicide resistance management. One way to make your crop more competitive is to increase seeding rates to produce higher plant populations. In this episode of RealAgriculture’s Resistance Management School, University of Manitoba weed scientist… Read More
There’s a new tool available for growers in the fight against herbicide-resistant weeds, such as Canada fleabane. Corteva Agriscience has launched Elevore, a Group 4 herbicide option for pre-plant burndown of broadleaf weeds, including glyphosate-resistant Canada fleabane, in both field corn and soybeans. Last week at Canada’s Outdoor Farm Show, Dave Kloppenburg, Corteva’s Canadian category leader… Read More
Herbicide resistance is nothing new to Ontario farmers. It all started in 1973 when triazine-resistant lamb’s-quarters were found on a farm near Ripley, Ontario. Group 2 herbicide-resistant weeds were first documented in 1996. Fast forward to 2018, and we find that the province is now home to a host of glyphosate-resistant weeds including Canada fleabane, giant… Read More
Resistance One of the many things to think about while managing herbicide resistance on your land is the rotation of modes of action. Many growers don’t realize how much Group 14 herbicide they are using. While there are many common add-ins used with glyphosate, more than half of them are from Group 14 — which,… Read More
Are we doing enough to reduce the herbicide-resistance weed seedbank on Ontario farms? That’s a question AGRIS Co-operative agronomist Dale Cowan wants farmers in the province to consider when they’re planning their weed control programs for this year. Cowan recently attended the Commodity Classic in Anaheim, California, where he talked with farmers from Mississippi who… Read More
Planting is just around the corner, and if you’re in full-on crop planning mode you’re likely curious about what’s new, what’s old, what’s repackaged, what’s the best bet for herbicides in 2018. Lucky for you, Ontario Ministry of Agriculture, Food and Rural Affairs weed management specialist Mike Cowbrough faces an avalanche of these questions every… Read More
