A report shows overall insensitivity of sclerotinia to three fungicide groups hasn’t changed in a big way between 2010 and 2024 — but shows some sclerotinia populations have been discovered with elevated insensitivity to all three.

Good news, bad news for fungicides meant to fight stem rot in canola
A report lays out various levels of resistance and adaptation found in disease samples
Timing a fungicide for mycosphaerella blight in peas
It pays to know whether and when to spray
Knowing what kind of blight is in your pea field — before firing up the sprayer — can help you avoid an expensive mistake, as just one of the two common blights affecting peas can be treated with a fungicide.
FEED ME: Can well-fed plants fend off diseases and insects?
We examine an Idaho farmer’s program for crop self-defence
Blake Matthews works with agronomist Jared Cook on an intensive cropping program that improves plant health and soil health, reduces pesticide use and somewhat increases profits. We check in with Prairie experts to see how that program’s principles could work in this region.
Later is better when spraying for fusarium
Some advice to growers still recommends spraying earlier, but researchers say recent studies point in the opposite direction
Research and field testing in North Dakota indicate the best time to spray for fusarium head blight is when the first flowers appear in the centre of the wheat head.
Chemical costs are down — but for how long?
A new report highlights price drops in agricultural chemicals, but rising raw material costs and market volatility could reverse the trend
As the agricultural landscape braces for uncertainty, securing supplies now could be a smart move for the season ahead.
Digital supercluster backs precision fungicide development
Project aims at wheat leaf rust, reducing pesticide load
A West Coast ag tech company in the crop pest control business is setting its sights on wheat leaf rust, with support from one of Canada’s five research superclusters — but not the cluster you might expect. Out of the five federally-supported superclusters launched in early 2018, Protein Industries Canada has been most closely linked […] Read more
Still no magic bullet for fusarium head blight
There’s still no cure, but at least there’s no sign of fungicide resistance. Yet
“We have no magic bullet.” When Randy Kucher, associate professor at the Crop Development Centre/Department of Plant Sciences at the University of Saskatchewan, said that at the beginning of his presentation, the mood in the roomful of CropSphere attendees deflated just a bit. Fusarium head blight has stolen yield from many durum and spring wheat […] Read more
When is my canola in the right stage for a fungicide?
Q & A with Nutrien Ag Solutions
Q: How do I determine the correct bloom stage in canola to apply a sclerotinia fungicide? A: Proper timing of fungicide for sclerotinia control requires regular scouting. The recommended timing is application at the 30 per cent bloom stage. Application prior to this stage can result in reduced control as petals susceptible to infection have yet to emerge. […] Read more
Should I treat my seed with a fungicide?
Q & A with Nutrien Ag Solutions
Q: Why should I treat my seed with a fungicide? When should my seed treatment include an insecticide? A: Seeds and seedlings are vulnerable to many soil-borne and foliar pests. Insects and pathogens can destroy germinating seeds and young plants, which are relatively tender and lack food reserves to recover from injuries or to survive […] Read more
Pearce: Multiple modes of action an emerging reality for fungicides
As growers face more challenges from weeds, diseases and insects, many researchers, agronomists, advisers and farmers have shifted thinking from “control” of pests to “managing” them. Some of this trend is attributable to single-mode-of-action products and a reliance on one or two chemistries or technologies — but the adaptability of weed, disease and insect species […] Read more
