Ground beetles are some of the most abundant natural enemies for crop insect pests, but their free services in the field often remain overlooked and under-appreciated, says an entomology professor from the University of Manitoba. “They’re far more abundant than most people realize, but many of our species are really restricted to the ground and… Read More

Those green plants sticking out of the crop — are they regular redroot pigweed, or a much nastier pigweed species, such as waterhemp, or even Palmer amaranth? This has become an increasingly common question for farmers and agronomists on the eastern side of the Canadian Prairies as waterhemp that’s resistant to multiple herbicide groups continues… Read More
True armyworms hungry for grassy plants, including wheat, have arrived in large numbers in parts of the Prairies this summer. The pest, which migrates north as a light brown moth, arrived in Manitoba during the last week of May, explains John Gavloski, entomologist with Manitoba Agriculture, in this armyworm-focused Wheat School episode filmed at the… Read More
Advancements in RNA interference (RNAi) technology could soon unlock new tools for managing canola pests and pathogens, such as sclerotinia and flea beetles. RNAi — ribonucleic acid interference — involves targeting specific RNA sequences in a disease or pest, rather than targeting entire proteins or enzymes, as is the case with current pesticides. It’s a… Read More
What’s the best strategy for applying fungicide in highly variable corn fields where plants range in maturity from three to 10 leaves? That’s a question BASF agronomist Ken Currah tackles on this episode of the RealAgriculture Corn School. He says that’s been the story of many corn fields this year, especially on clay soils where… Read More
The federal government announced a series of changes to its policies around pesticide use on Tuesday, including the introduction of a ban on cosmetic uses of pesticides on federal land and the end of a nearly two-year pause on reviews of maximum residue limits (MRLs). CropLife Canada, which represents companies that make crop protection products,… Read More
There’s plenty of research data that shows applying a T3 fungicide to winter wheat will deliver a yield benefit, even in a dry growing season. RealAgriculture agronomist Peter Johnson says dry growing conditions tend to drive down fusarium head blight and other disease pressure, resulting in less yield loss, but the fungicides also increase the… Read More
The federal government is lifting its nearly two-year pause on reviews of pesticide maximum residue limits (MRLs), while also introducing a ban on cosmetic pesticide use on federal land. Ministers representing Health Canada, Environment and Climate Change Canada, and Agriculture and Agri-Food Canada shared the multi-pronged announcement on Tuesday as part of the government’s larger… Read More
There are a few different scenarios to look at when it comes to deciding whether or not to spray a fungicide on wheat. Jeremy Boychyn, agronomy research extension manager with the Alberta Wheat and Barley Commissions, says there are four key times that producers are either already going over the field, or there is potential… Read More
