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
Verticillium stripe — a disease first discovered in Western Canada in 2014 — appears to be taking advantage of the stress to canola plants caused by an old, familiar disease pathogen. While research to understand Verticillium longisporum in the Prairies is still in its early stages, there’s a hypothesis that its prevalence in a canola… Read More
Canola and soybean growers will have a new fungicide option to help protect their crops from sclerotinia and white mould. Corteva Agriscience has launched Viatude, a fungicide that offers multiple modes of action for resistance management. It also contains a unique combination of two highly effective ingredients, including Corteva’s proprietary active, Onmira, the company says…. Read More
What did growers learn about growing edible beans in 2022? Growers experienced much different conditions in the key growing regions, but overall the season was generally positive. In Manitoba, a good crop prevailed after a wet spring delayed planting. In many cases, growers experienced record yields. Further east, dry conditions stressed the Ontario crop but… Read More
Bacterial leaf streak is not a particularly new disease to Canada but there are ongoing projects to increase identification and prevention of the disease. Dr. Constanza Fleitas, with the cereal and flax pathology group at the University of Saskatchewan, says that bacterial leaf streak is a growing issue in the U.S., and there are increasing… Read More
Tar spot has been spreading across North American corn growing regions ever since the leaf disease was first detected in 2015. Characterized by tar-like speckling on the upper surface of corn leaves, the fungal pathogen can deliver yield hits ranging from 20 to 60 bushels per acre (in highly infected fields). On this episode of… Read More
Are drop hoses that travel through the canopy the best way to apply in-crop fungicides? That’s a question Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) application technology specialist Jason Deveau has worked on for the past four years. It all started in 2019 when Deveau joined forces with OMAFRA plant pathologist Albert Tenuta… Read More
Winter is a great time to recalibrate your approach to managing wheat diseases and applying fungicides. That’s the message Penn State University plant pathologist Alyssa Collins shared with agronomists attending the Ontario Certified Crop Advisors annual meeting earlier this month. It’s a dormant period for humans and also for fungi and plants, says Collins. “So… Read More
Protecting grain crops from costly plant diseases and making crop production more resilient to climate change are two goals a new $2-million gift to the University of Guelph from Grain Farmers of Ontario (GFO). Announced at the close of the Ontario Agricultural Conference, the funding will support a new GFO professorship in field crop pathology… Read More
