Resistance to Group 2 herbicides has been common and assumed in many cases with kochia in Western Canada for years, but weed survey results show glyphosate (Group 9) resistance in the invasive tumbleweed species has exploded in recent years. In 2013, less than 1 per cent of kochia populations sampled by Agriculture and Agri-Food Canada… 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
FMC Corporation has obtained a new mode of action classification for its proprietary herbicide molecule, tetflupyrolimet. It is the first active ingredient in the Herbicide Resistance Action Committee and Weed Science Society of America Group 28. As well, it is first new herbicide with a novel mode of action in the crop protection industry in… Read More
Herbicide resistance is unfortunately on farmers’ radars lately. Crop diseases becoming resistant to existing fungicides is thankfully not super common, but fungicide resistance has and will happen. To discuss how resistance develops, best management practices to avoid it, and which chemistries are most at risk, RealAg LIVE! host Shaun Haney is joined by Colleen Redlick… Read More
Weed scientists in the southern U.S. say they have confirmed the first known case of broadleaf resistance to glufosinate — the active ingredient in Liberty herbicide. The resistance to the widely-used herbicide was found in Palmer amaranth plants from two fields in Mississippi County, Arkansas. The pigweed plants caught the attention of University of Arkansas… Read More
Corteva Agriscience’s Prominex herbicide with Arylex active has been approved by Health Canada’s Pest Management Regulatory Agency (PMRA). Tailored for Western Canadian cereal farmers, this new tool is aimed to control both annual and perennial broadleaf weeds such as Canada thistle, cleavers, dandelion, kochia, hemp-nettle, and wild buckwheat. Kelly Bennett, western Canada herbicides category leader… Read More

Glyphosate-resistant waterhemp was first identified in Ontario in 2014. Since that time the weed, which hails from the pigweed family, has spread across the province with confirmed sightings in 14 counties in 2019. To make matters more troubling, waterhemp resistance continues to grow beyond glyphosate, and now includes multiple resistance to Group 2, 5, 9… Read More
There’s still room for privately-owned, smaller players in the seed business, according to BrettYoung. In this episode of RealAg LIVE!, BrettYoung’s Rene Mabon and Eric Gregory discuss how new ideas move variety offerings forward, how partnering on research and development with global players keeps the company on the leading edge, and what has changed for… Read More
A glyphosate add-in can help maximize early-season weed removal and manage resistance. Sending glyphosate out alone for your spring burnoff is something that might end up costing you dearly down the road. According to weed scientists, continuously using a herbicide with a single mode of action accelerates herbicide resistance. Hitting the same weeds at the… Read More
The battle against weeds puts farmer against nature’s innate ability to adapt and overcome. The advent of herbicides tipped the odds in farmers’ favour for a time, but only until several weed species developed — and continue to develop — resistance. Dr. Hugh Beckie, a former weed scientist with Agriculture and Agri-Food Canada, is now… Read More
Today, on RealAg Radio: The agronomics of falling number, and thinking ahead to 2020, with Jeremy Boychyn of the Alberta Wheat and Barley Commission’s; Weed resistance in Australia, with Hugh Beckie, of the Australian Herbicide Resistance Initiative; An update on western bean cutworm and corn earworm in Ontario, with Ontario Ministry of Agriculture, Food and… Read More
As growers actively manage herbicide-resistant weeds on their farms, many are also looking at how to secure future effectiveness of other crop protection tools, including fungicides and insecticides. In this first episode of a new season of RealAgriculture’s Resistance Management School, we take a look at the current state of fungicide resistance in field crops… Read More
In a move said to increase transparency, customer engagement, and sustainability, Bayer AG has announced a series of measures to address concerns recently raised as the company took over Monsanto last year. “We will continue to advance our standard, driven by our commitment to a better life for this generation and generations to come,” says Werner… Read More
Herbicide resistant weeds are spreading across counties, the country, and the continent. Weed seeds are hitching a ride on wind and water and being transported by everything from machinery and migrating geese to ducks and earthworms. On this episode of RealAgriculture’s Resistance Management School, we’re joined by University of Guelph Ridgetown campus weed researcher, Dave… Read More
