In this week’s episode of the Word, host Peter Johnson takes us through a few of his key learnings in the last month with a discussion on the 38 million acre problem — herbicide resistance. Then Johnson talks geese in wheat, building magnesium, cover crops, tillage, and spreading/piling manure. Have a question you’d like Johnson… Read More

In addition to Family Day, Louis Riel Day and Presidents’ Day, it’s Agronomy Monday on RealAg Radio. Today’s lineup, with host Kelvin Heppner, includes: Daryl Ritchison, meteorologist with NDSU, on his history project interviewing people who farmed through the ’30s, and whether the prairies are ready for another serious dry spell Kelly Bennett of Dow… Read More
Canadian corn and soybean growers have a new tool to tackle resistant and tough-to-control weeds. Zidua SC, a new Group 15 herbicide from BASF, will be available in 2018. Deven Esqueda, BASF corn and soybeans crop manager, says the herbicide is labelled for use in herbicide-tolerant soybeans and field corn. With the active ingredient pyroxasulfone,… Read More
Agronomy Monday, hosted by Shaun Haney and Kelvin Heppner, featuring: Australian agronomist and farmer Craig Hole discussing the cost of herbicide resistance in Australia, how Aussie farmers are managing resistance issues, and his advice for North American farmers (recorded at Ag in Motion near Saskatoon last week); Changes to AgriInvest under the new five-year Canadian… Read More
Herbicide resistance is not new in Canadian agriculture, but managing it is becoming a higher priority as the scope of herbicide resistant weeds grows. In Western Canada, number one on the ‘economically important’ list is resistant wild oats, notes Bob Blackshaw, weed scientist with Agriculture and Agri-Food Canada, in this Wheat School episode. “It’s the… Read More
By now, farmers are all too familiar with weed populations developing resistance to herbicides (sometimes more than one). Given what we know and understand about how resistance develops, how concerned should farmers be about diseases becoming resistant to fungicide applications? Scott Henry, with Bayer, sat down with Shaun Haney to break down this not-so-straight-forward topic. The… Read More
Syngenta and DuPont say they expect a new herbicide chemistry class to be created by 2023, after announcing the publishing of a joint patent on Monday. Collaboration between the two companies on the project started in 2015 and has resulted in a patent for “Substituted cyclic amides and their use as herbicides.” “We are very… Read More
The number of herbicide-resistant weed cases is growing while the list of modes of action available for controlling these weeds is not, so farmers in Western Canada have shifted back to soil-applied herbicides, including some old chemistries, like Edge and Avadex. “We’re going full-circle here. These are older chemistries, but they’re coming back in and growers… Read More
Gowan Company has announced a deal to acquire the entire DNA (dinitroaniline) herbicide portfolio from Dow AgroSciences, including popular herbicides Treflan and Edge. The products to be acquired by Gowan have active registrations in 22 countries including the USA, Canada, Japan, Australia, and parts of Europe. “We are enthusiastic to be able to acquire these… Read More
DuPont Crop Protection has announced the registration of new DuPont Express FX herbicide for pre-seed weed control before planting spring wheat, durum or barley. Express FX delivers two modes of action, Group 2 and Group 4, as an add-in to glyphosate. Tank-mixed with Group 9 glyphosate, that makes three modes of action for “an additional… Read More
Herbicide resistant wild oats are pretty easy to identify, says Neil Harker, a research scientist in weed ecology and crop management at Agriculture and Agri-Food Canada’s Lacombe Research Centre. “You generally see them in patches. If you see [wild oats] in real straight lines, then you suspect a sprayer error, but if you just see them in… Read More
Wheat and barley growers in the black soil zone now have two new tools, based on the new Group 4 active ingredient Arylex by Dow AgroSciences. Paradigm and Pixxaro, which contain Arylex, are now registered and will be available for use in 2015. Dow AgroSciences says that these two new broadleaf herbicides are designed to… 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
The Canola Council of Canada is alerting farmers that existing genetic resistance to clubroot may not prove effective in all Alberta fields. Dr. Stephen Strelkov of the University of Alberta led the analyses of several field samples, and data suggests that some forms of clubroot resistance are “no longer functioning well” against the disease in… Read More
The factors involved in weed management decisions vary greatly from farm to farm, so many herbicide research projects deal with variances in weather, soil and weed population presence. Products and even rates, for example, will often be catered to a specific soil zone. And, with the growing threat of herbicide resistance, it boils down to more… Read More
