Resistance to Bt corn rootworm hybrids has developed in Ontario and growers are asking: what’s the best strategy to control the yield-robbing pest if in-seed technology fails? Resistance has been confirmed in several fields in Huron, Perth and Durham Counties in Ontario and the problem is likely even more widespread, says Tracey Baute, Ontario Ministry… Read More
Selecting the right hybrids can make or break the profitability of a corn crop. There are a multitude of factors that combine to produce high-yielding, profitable harvests, but if growers make the wrong hybrid choices they’ll need some luck and good fortune to produce a successful crop, says University of Guelph associate professor Dr. David… Read More
Tar spot has moved through the U.S. Midwest, into Michigan and Wisconsin, and now officially calls Ontario home. Ontario Ministry of Agriculture, Food and Rural Affairs’ plant pathologist Albert Tenuta has seen the evidence in a field near Ridgetown, Ont., and there are also reported sightings of the corn leaf disease in Lambton and Essex… Read More
The better the job done at planting the better the yield potential of a corn crop. That much we know, but when planting into less-than-ideal conditions, like the spring of 2020, environmental factors can really wreak havoc on your end yield potential. Luckily, paying attention to seed singulation at planting time can help. “There’s no… Read More
Have you ever wondered just exactly how your corn develops in the cob? Understanding how corn makes a cob, successful kernels, and packs in starch can be a key component of an agronomic plan. “This top part is the tassel, and that is the male part of the plant,” says Sara Meidlinger, market development agronomist… Read More
Grain corn acres in Western Canada this year might be down, but there’s potential for some big yields, assuming the crop can avoid late season pitfalls. “For growers who held onto those acres, they’re going to be rewarded, no doubt. Grain corn crops here in southern Manitoba look especially strong,” says Alana Serhan, market development… Read More
A three-year trial conducted by Farming Smarter on grain corn production under dryland conditions in four Alberta locations is yielding some interesting results. The trial at Lethbridge, Vauxhall, Bow Island, and Medicine Hat, was conducted between 2015 and 2017, and included agronomic factors that may affect dryland grain corn production, including plant population, row spacing,… Read More
Corn fields across Ontario are full of variable plant development and that should be a concern for growers, says University of Guelph crop researcher Dr. David Hooker. Fields are littered with areas of yield-compromising backward and slow-to-develop plants. Hooker believes corn variability is even more apparent this year due to significant weather challenges; with cold… Read More
Tillers are a totally normal physiological process in corn — since it is a grass like wheat or barley — and they’re nothing to be concerned about. They’re also nothing to get excited about either, as unlike wheat or barley, tillers don’t contribute to yield. In this episode of Corn School (this time in the… Read More
All the “knee-high by the first (or fourth) of July” photos have been posted on social media, with the crop looking nice from above; but what’s going on below the canopy? Now is the time to check weed populations and assess herbicide performance, says Jeanette Gaultier, senior technical services specialist with BASF, joining us for… Read More
Every corn crop is different. The year-over-year variables really play into a fungicide timing strategy, but the most important question to ask when strategizing for fungicide timing may be: “What is your corn crop doing right now?” Ken Currah, with BASF Canada, joins RealAgriculture’s Bernard Tobin for this episode of the Corn School to walk… Read More
If you applied a pre-emergent herbicide before planting your corn and didn’t get the moisture to activate it, don’t despair and don’t feel like you’ve thrown some money down the drain. You still get weed control during that critical weed-free period, says Rob Miller, technical development manager with BASF. As you can see in this… Read More
The hangover effects from a wet fall are giving farmers in parts of Western Canada a headache this spring. Saturated soil conditions right until freeze-up forced fieldwork that normally happens in fall to be delayed until spring. As a result, heavy harrows, vertical tillage machines, traditional cultivators, and even fire — all the tools in… Read More
With June arriving this week, corn is rushing ahead and growing rapidly. Now’s the time for growers to get out and scout fields to identify planting issues, determine yield potential and start fine-tuning your management plan, says Kinburn, Ont., agronomist Paul Sullivan. On this episode of RealAgriculture’s Corn School, Sullivan notes that stand assessment and… Read More
Should you go ground or air? That’s the question many growers struggle with as they try to determine the best method of applying disease-fighting fungicide to their growing corn crops. On this episode of RealAgriculture Corn School we tackle that question with two of North America’s leading plant pathologists — University of Kentucky’s Kiersten Wise… Read More
