Could fungicide resistance develop on your farm? The answer to that question really depends on how you deploy fungicides in your fields, says Agriculture and Agri-Food Canada research scientist Kelly Turkington. On this episode of RealAgriculture’s Resistance Management School, Turkington explains that fungicide resistance really is a numbers game. He notes that a barley or… Read More
Fungicides play a key role in helping manage disease in pulse crops across the Prairies. But growers need to be vigilant to prevent fungicide resistance and ensure they have the tools required to fight yield-robbing diseases, says Alberta Agriculture and Forestry pulse research scientist Robyne Bowness Davidson. On this episode of RealAgriculture’s Resistance Management School,… 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
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
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
Even if you don’t think you have herbicide resistant weeds in your fields, the best management practice might be to treat your fields as if you do. That’s the advice of Linda Hall, associate professor in the Faculty of Agriculture Life and Environmental Science at University of Alberta, in this episode of the Resistance Management School. There… Read More
There are a number of reasons why herbicides sometimes fail to control weeds. Perhaps surprisingly, one of the easier things to rule out is whether the weed is herbicide resistant. Ontario Ministry of Agriculture, Food and Rural Affairs weed specialist Mike Cowbrough says many universities across Canada conduct testing for herbicide resistance, but growers have… 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
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
Often when we think of herbicide resistance, as producers, we think it means we have to stop spraying certain products completely. This is not always the case, and as Tom Wolf of Sprayers 101 and AgriMetrix explains in our latest Canola School episode, why and how you can take some extra steps from the sprayer… 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
Soybeans are a relatively new crop for many farmers in Western Canada. For many farmers, this brings a second RoundUp Ready crop (or possibly third) into rotation. Because of this, controlling volunteer canola ahead of the soybean crop is crucial, as high canola populations can have a significant yield impact, and more costly, as a… Read More
