Fungicide, glyphosate don’t hurt your hard red wheat quality

In terms of grain quality, this University of Manitoba-led research finds weather and variety matter most

By Don Norman May 9, 2025

The results of this study may not seem all that surprising: everyone expected weather and genotype to be the most impactful factors on wheat quality. But this research hadn’t been done before, so it offers up the good news that fungicides and glyphosate aren’t making things worse.

Steps to stop blackleg in canola

Agronomists and canola growers have many proven steps to manage blackleg disease in canola. Genetic resistance has been an extremely effective tool, and will remain so — as long as that resistance matches the blackleg races in a field

By Jay Whetter April 26, 2025

Blackleg disease, caused by the pathogen Leptosphaeria maculans, is common in canola across the Prairies. It can cause very high yield loss in cultivars susceptible to the predominant blackleg races in a field. The two best defences are: Seed treatment and early-season fungicides can also help, especially if the first two are compromised. This article will […] Read more

Managing against fusarium takes a multi-part strategy

Tweaking fungicide timing could provide farmers with better control

By Mark Halsall March 7, 2025

Kelly Turkington, a longtime plant pathologist for Agriculture and Agri-Food Canada in Lethbridge, strongly supports the notion that an integrated approach to managing fusarium head blight (FHB) offers the best chance of success for cereal producers. Even so, Turkington says, in much of Manitoba and northeastern Saskatchewan, that strategy hasn’t always worked as well as […] Read more

Pioneer levels up against sclerotinia

Corteva’s new canola hybrid delivers fungicide-equivalent protection

By Don Norman February 26, 2025

Fungicide-equivalent protection against sclerotinia has long been an elusive target for canola breeders — but Pioneer appears to have cracked the code. The Corteva-owned seed brand released its P617SL hybrid commercially in 2024, and the company says its trial data backs up the fungicide-equivalent claim. While the Canola Council of Canada can’t speak to specific […] Read more

More than one way to fight fusarium head blight

An integrated approach, using multiple best practices, can offer better chances of success

By Mark Halsall February 15, 2025

Fusarium head blight has been a stubborn threat to cereal crops in Western Canada since the 1990s. Some years are worse than others, but when the conditions favour this fungal pathogen, fusarium can cause significant losses in yield and crop quality in wheat, barley, oats and corn. The two primary weapons against fusarium — fungicides […] Read more

Revisions for Raxil, other labels

By Dave Bedard January 29, 2025

Health Canada’s Pest Management Regulatory Agency in late November weighed in with its final re-evaluation on the toxicity risks of tebuconazole. Apart from its use as a wood preservative, it’s best known to farmers as a Group 3 active ingredient in Bayer’s Raxil, Prosaro and Folicur, Corteva’s Straxan and other foliar fungicides and seed treatments.

Agronomy and the Law: Be careful what you recommend

By Kalen Oram, Rochelle Blocka December 20, 2024

Recommending various herbicides, fungicides and pesticides to farmer and ag-retail clients is an important aspect of an agronomist’s role. These recommendations must be tailored to each grower’s fields in an economically viable manner and, in the case of pesticides, recommendations and the usage and storage thereof, must be within the law. In fulfilling your duty […] Read more

Lentil fungicide gets expanded label

By Grainews Staff November 25, 2024

Corteva this summer picked up an expanded label for its Zetigo PRM fungicide — a Group 21 product which, you may recall, had a soft launch last summer for use against diseases such as ascochyta blight and anthracnose, but in lentils only. The product had its full launch this year and Health Canada’s Pest Management […] Read more

Biologicals aren’t the silver bullet

The products can be complements, not replacements, for other inputs

By Robert Arnason October 7, 2024

Glacier FarmMedia — Biological products have been touted as replacements for synthetic chemistry and fertilizer in crop production, but that may be a false promise. According to one pitch, if farmers add biological X to the soil, they can cut nitrogen rates by 15 pounds per acre. According to another, biological Y can control a […] Read more
