This year, the organizers of the Crop Diagnostic School in Carman, Manitoba, decided to do something a little old-school. “We decided to demo soil-applied herbicides here at the farm this year for the Diagnostic School, in part because we’re seeing an increased use in the products,” Jeanette Gaultier explains in the following interview. Gaultier (who may or… Read More

Certain herbicides have done plenty of heavy lifting when it comes to the fight against weeds over the last number of decades, but as herbicide resistance becomes more common, it’s important to spread out that workload whenever possible. Corn is often a crop where there are more herbicide options, explains Jeanette Gaultier, technical services specialist… Read More
Wheat and barley growers in Western Canada have a new herbicide to aid in the fight to control troublesome weeds, such as herbicide resistant kochia. Corteva Agriscience has announced registration of OnDeck herbicide, a product that provides post-emergent weed control for wheat (durum spring and winter) and barley farmers in the brown soil zones. OnDeck… 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
Most prairie growers know that adding another herbicide to their spring glyphosate application pays big dividends. First, they’ll see better and more consistent weed control. Second, starting with a clean field helps protect yield potential and third, having another mode of action (or two or three) in the tank will help avoid resistance and thus… Read More
Waterhemp that’s resistant to multiple herbicide groups continues to march across Ontario, but growers still have options to control the weed. There’s also emerging proof that integrated management could help growers take the fight to the spreading yield robber, says University of Guelph weed scientist Dr. Peter Sikkema. At the Ontario Agricultural Conference earlier this… Read More
Fungicides are integral for preventing disease in many pulse crops, however, just like how weeds have become resistant to certain herbicides, diseases can become resistant to commonly-used fungicide chemistries. The majority of pulse fungicides on the market in Western Canada contain a Group 11 — the category of fungicide most likely to be overcome by… Read More
Whether you’re a first-time lentil grower or an experienced farmer, using a complete-solution herbicide is key to maximizing yield. India has dropped in-bound tariffs on lentils which means lentil acres could be more profitable this year. Lentils, however, are not the easiest crop to grow. One of the key problems for growers is a lack… Read More
Wheat growers looking to manage resistance without compromising their crop rotation have a new herbicide to add to their management toolbox. Syngenta Canada has launched Erebus Xtreme, a grass and broadleaf cereal herbicide that combines Group 2 and Group 4 active ingredients in a pre-mixed liquid formulation. When using Erebus Xtreme, Syngenta says cereal growers will be able to effectively… Read More
The escalation in the cost of crop inputs, including glyphosate and glufosinate, has some farmers looking for ways to save money. Some farmers have asked if trimming back herbicide rates is a viable option. Going in with a half rate might seem like a good idea, but in the long run it can be a… Read More
Herbicide strategy for in-crop applications in canola first requires knowing what weeds are out there, and keeping in mind that two applications is an option. In this Canola School episode, Jaeda Hoppe, field crop agronomist with UYMI Agronomy at Biggar, Sask., says that two in-crop herbicide applications is likely if the weeds are there and… Read More
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
