Protecting your corn crop from disease throughout the growing season can be a challenge. On this episode of RealAgriculture’s Corn School, Ontario Ministry of Agriculture, Food and Rural Affairs plant pathologist Albert Tenuta and University of Guelph associate professor Dave Hooker team up to offer tips on how to select a fungicide and stage the… Read More
How does corn crop emergence after planting play into ear and cob development, and eventually yield? Earlier in the growing season, Sara Meidlinger, market development agronomist at PRIDE Seeds, set up some flag tests that measured emergence in 1/1000th of an acre, in seven hybrid variety strips. In this Corn School episode, Meidlinger goes over the results… Read More
Splitting nitrogen in a corn crop can increase profitability and benefit the environment, but to be successful on both counts growers need to keep a sharp eye on the weather. That’s the conclusion drawn by University of Guelph researchers Tasmia Kabir, Aaron Delaporte, Joshua Nasielski, and Alfons Weersink after looking at 19 years of weather data… Read More
Tar spot is taking a bite out of yields in some Ontario corn fields but there is hope that growers will have effective tools to manage the leaf disease. Characterized by tar-like speckling on the upper surface of corn leaves, the fungal pathogen has been delivering yield hits ranging from 20 to 60 bushels per… Read More
Trees tend to generate an emotional response from most cash croppers — some growers love them, others hate them. The joy or angst typically stems from the impact the large, expansive perennial plants have on growing crops. On this episode of Corn School, RealAgriculture agronomist Peter Johnson looks back at the research of Dr. Charles Baldwin who… Read More
Corn rootworm can be a major yield-robber and this year more than most, it’s on everyone’s minds. Amanda Craven, agronomist at PRIDE Seeds is joined by Bernard Tobin for this Corn School episode to talk resistance management, how rotation helps, and how corn rootworm affects yield. “What we’re seeing this year, in our corn-on-corn fields,… Read More
Perennials and winter annuals like dandelions, shepherd’s purse, and even chickweed can be tough to control at the best of times. So, what can make a perennial and winter annual weed control strategy more effective in corn? Going back to a previous conversation between Rob Miller, agronomist at BASF, and Bernard Tobin about using tillage… Read More
How does strip tillage impact a corn plant’s ability to access and take up nutrients? On this episode of RealAgriculture’s Corn School, Ben Rosser, corn lead at Ontario Ministry of Agriculture, Food and Rural Affairs, looks at fertility research plots that compare how corn performs in both conventional tillage and spring strip tillage systems. In… Read More
Corn is often described as a diva. It can thrive in the right conditions, but it does not like competition. That’s especially evident when corn plants have to compete with weeds for moisture in dry conditions, as seen in Western Canada and the Northern Plains of the U.S. in 2021. “There have been many studies… Read More
