You have several corn fields and only one of you — how do you prioritize which field gets fungicide first? 2015 is shaping up to likely be a high disease pressure year, says Albert Tenuta, field crop plant pathologist with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), and a little planning now… Read More

Skipped plants in a corn row aren’t always due to mechanical error or seedling blights. Early insects like wireworm or grubs can kill plants rather stealthily, leaving gaps in a row or neat leaf damage, while cutworm can clip off a patch of plants overnight. Knowing which insect causes what damage is important when assessing… Read More
The initial frost damage assessment within days of the late May frost had many farmers breathing a sigh of relief, as damage seemed to be limited to just the first few leaves and regrowth was evident. Within a week, however, more than a few farmers were beginning to get concerned about whether or not that… Read More
We’re 72 hours out from the late May frost that occurred across much of Ontario, and farmers are busy scouting corn fields for damage. Thankfully, most farmers and crop scouts are already seeing green signs of re-growth — a welcome sight — but reports are trickling in of badly damaged areas within fields. Why did… Read More
What’s the number one question you ask of yourself or your agronomist as you plan your corn crop? It’s likely, “What’s the right rate of nitrogen for this field?” It’s the golden question, as Dr. Dave Hooker, of the University of Guelph-Ridgetown, says, and the answer can be as low as zero or as high… Read More
Is your planter ready to roll? Corn planting season will soon be here for growers in Ontario and Western Canada. While it’s been a cool spring in Ontario, an early melt in Western Canada meant some fields were dry enough to plant several weeks ago. However, the date on the calendar and the temperature reading on the soil… Read More
With corn planting season around the corner, the annual routine of getting planting units ready for a new growing season is well underway. The planter setup and calibration process should account for the size of corn seed going through the planter, notes Dieter Schwarz of Pride Seeds in this latest Corn School episode. “Look at that bag of… Read More
Do you manage your corn crop differently, based on whether or not you’ll be using a fungicide or topped-up nitrogen rates? That may end up being a new recommendation, as research is beginning to offer clues on how each input works with the other — sometimes providing not just additive benefits, but synergistic ones (think:… Read More
“When the land is dry, it’s no longer about planning, it’s about execution — it’s our Super Bowl.” That’s a quote from Pride Seeds’ Ken Currah, who caught up with Bernard Tobin for the above Corn School. Currah and Tobin, sheltered from the rain, discussed the importance of preparing for seeding, and having a plan… Read More
Farmers fought hard (sometimes through deep snow that disappeared soon after) to get the 2014 Ontario corn crop off, but there’s as much as 5% of the crop still standing. There’s really nothing you can do about the crop being out until the snow finally melts, but farmers who have been keeping eye on their… Read More
If you’ve noticed increasing levels of northern corn leaf blight in some of your fields, it could be that the hybrids you’re planting don’t have the right gene to resist infection. That’s because the pathogen has evolved to bypass some of the older sources of resistance, says Albert Tenuta, field crop pathologist with the Ontario… Read More
In the cattle industry, interest in new corn varieties stems from a desire to increase efficiency and production, whether utilized as a grain source, ensiled or left standing for winter grazing. Ensiled, corn offers high energy, a key to high milk production. And, although much of a silage’s quality is determined by in-field management, harvest… Read More
Do you plan on taking a nitrate-nitrogen soil samples this spring, before planting? The test for nitrate-nitrogen levels can provide key information in how much fertilizer should be applied for a growing corn crop. And, making that decision gets easier and easier. The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) has a handy table with… Read More
The Ontario Corn Committee (OCC) is well known for its hybrid trials, which compare hybrids for yield potential in various regions across the province, but, thanks to grower input, this year might look a little different. 2011-2014 OCC Hybrid Corn Performance Database “The Ontario Corn Committee has decided that in 2015, we will begin a… Read More
31-33% moisture: that’s when corn reaches physiological maturity, or black layering, according to Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA). But, harvesting corn above 28% can result in damage to the grain, difficult marketing and the burdens of attempting to dry in storage. This late in the season, stalk quality may make the… Read More
