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
Record yields in 2022 after a late start are raising some questions about the assumption that earlier is always better for planting corn in Manitoba and other northern growing areas. Historical averages in Manitoba show a downward trend in yield with each week that passes in May, but the 2022 crop set a new bar… Read More
A properly calibrated planter can make a key contribution to corn yield but could the planter wheels be causing yield-robbing soil compaction? Ontario Ministry of Agriculture, Food and Rural Affairs corn specialist Ben Rosser says it’s important for growers to be aware of soil compaction on or around corn rows during planting. On this episode… Read More
Where should growers place fertilizer in strip-till strips to best protect the seed from injury while optimizing nutrient uptake? Ontario Ministry of Agriculture, Food and Rural Affairs corn lead Ben Rosser says Ontario does have “safe rate” recommendations for in-furrow and 2″x 2″ planter banding but no guidelines are currently available for strip-till fertilizer placement….

This spring, corn growers will be planting different seed sizes ranging from large rounds to flats and small rounds. Does the seed size impact the potential yield growers can expect to combine this fall? On this episode of the RealAgriculture Corn School, PRIDE Seeds agronomist Olivia Noorenberghe notes that all seed, regardless of size, carries… Read More
Planting corn at a uniform depth across the field is a key driver of even emergence and optimum yield. To ensure seed is planted at the desired depth, Kearney Planters operations manager Cullen Tinline says it’s critical for growers to ensure they ‘zero’ the row units before they roll into fields this spring. On most… Read More
What needs replacing? What’s worn out? What should I be looking for? Those are just a few of the questions Kearney Planters operations manager Cullen Tinline is fielding from grower customers as winter turns to spring. On this episode of the RealAgriculture Corn School, Tinline takes us on a planter inspection and offers maintenance and… 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
Corn yields in Ontario have been increasing 2 bu/ac, or one per cent per, year over the past 40 years. Where is that yield increase coming from? University of Guelph associate professor David Hooker says genetics (65 per cent) and agronomy (35 per cent) are the key contributors to bigger corn crops. Corn breeders can… 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
How does adding 100 crop heat units to the maturity of your corn hybrids impact the yield and profitability of the crop? Agronomist Peter Johnson tackles that question on this episode of the RealAgriculture Corn School with help from University of Guelph associate professor David Hooker. Earlier this year, Hooker took a deep dive into… Read More
