A wet growing season plus high humidity and moisture at tasseling has many Ontario corn producers asking about the potential for ear mould and gibberella when combines start to roll at harvest. On this episode of the RealAgriculture Corn School, host Bernard Tobin is joined by PRIDE Seeds product manager Matt Chapple for a look… Read More

European corn borer wreaked havoc for decades in cornfields across North America before the adoption of transgenic traits (Bt) in the late 1990s effectively punched out the pest. Earlier this year at Southwest Crop Diagnostic Days at the University of Guelph’s Ridgetown campus, Ontario ministry of agriculture entomologist Tracey Baute noted that the yield-robbing insect… Read More
What happens when a soil-applied herbicide application is followed by severe weather? For many herbicides it is business as usual, but in some cases a heavy rain can cause a typically safe product to injure the plant. On this episode of RealAgriculture’s Corn School, Ontario Ministry of Agriculture, Food and Rural Affairs weed specialist Mike… 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
Certain herbicides have done plenty of heavy lifting when it comes to the fight against weeds over the last number of decades, but as herbicide resistance becomes more common, it’s important to spread out that workload whenever possible. Corn is often a crop where there are more herbicide options, explains Jeanette Gaultier, technical services specialist… Read More
A European corn borer (ECB) population in part of eastern Canada appears to have developed resistance to a Bt protein commonly used in North American corn hybrids for preventing damage from the pest. On April 27th, the Canadian Corn Pest Coalition reported a sample of ECB collected near Truro, Nova Scotia, showed reduced susceptibility to… Read More
Soil acidity is an issue that’s gaining attention in the Northern Plains, especially in areas where no-till practices have been paired with high surface-applied nitrogen rates. “They’re seeing this advancing a lot faster in parts of North Dakota and Montana, under traditional zero till conditions where they broadcast urea fertilizer. They find they’re acidifying the… 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
The Christmas holidays are here! What better way to spend the time than catching some of the 30 Corn School episodes RealAgriculture published in 2022? We kicked off the season in January with Purdue University agronomy professor Dr. Tony Vyn who tackled the question: where does yield come from? Vyn notes that hybrid research over… Read More
Fungicides are a key tool in the tar spot management toolbox. But what’s the best time for growers to apply a fungicide to get optimal control of the disease and the best return on their crop protection investment? On this episode of the RealAgriculture Corn School we catch up with Ontario Ministry of Agriculture, Food… Read More
Why is there an irrigated corn crop growing in the middle of the University of Guelph’s Ridgetown campus? On this episode of the RealAgriculture Corn School, host Bernard Tobin takes a trip into the research maze to get a look at what happens in this corn misting nursery. Tobin first encounters University of Guelph associate… Read More
It appears in 2022 that Ontario growers have little to worry about when it comes to corn ear moulds such as gibberella contributing to elevated levels of mycotoxins in the corn crop. In late October, the annual Ontario corn ear mould and deoxynivalenol (DON) mycotoxin survey found 98 percent of samples tested low — less… Read More
Tar spot was found in many regions of Ontario again in 2022 but dry weather conditions throughout the growing season reduced the leaf disease’s impact on the corn crop. On this episode of the RealAgriculture Corn School, we pay a return visit to the provincial tar spot nursery at Rodney, Ont, where Ontario Ministry of… Read More
High residue, continuous corn, lack of nitrogen, drought — they’re all growing conditions that can make life stressful for corn plants. On this episode of the RealAgriculture Corn School, PRIDE Seeds agronomist Matt Chapple shares how seed companies stress test hybrids to ensure only the best, most resilient hybrids make it to market. He also… Read More
