Confused about what the new rules governing neonicotinoid-treated corn and soybean seed means for seed orders this fall? You’re not the only one — the Ontario government is hosting information sessions and webinars this week, but several questions and plenty of confusion swirl about what paperwork you must do to access neonic-treated seed. To help… Read More

We’re into the thick of the corn growing season, where you finally get to start seeing the real result of all the hard work that’s gone into this crop before now. The 2015 season has been a trying one for many Ontario growers as a great planting season gave way to too little, then too… Read More
Phosphorus deficiency is a common problem with corn planted into a rotation following canola. In its early stages, corn relies on mycorrhizae to help with the majority of phosphorus uptake. The trouble with corn following canola is that canola and other crucifer plants are not hosts for micorrhizae, so the beneficial fungi populations must be re-established…. Read More
It’s a great problem to have, but gains of an average four to five bushels per acre per year is possible with today’s corn crop if modern genetics are managed properly. Of course, “managed properly” is too general — if Ontario’s average corn yield per acre is set to surpass the 200 bushel mark in… Read More
We’re approaching a critical stage for corn — tasseling — and weather conditions in some areas are conducive to high disease development. Recently in the Corn School, we’ve talked prioritizing fields for a fungicide application and where and how to scout for leaf disease in corn, but did you know that there’s another factor at… Read More
Following frost and challenging weather conditions, it’s not uncommon to find wide staging variability in Ontario corn fields this year. Uneven development will complicate timing of fungicide and insecticide applications, notes Dale Cowan, senior agronomist with AGRIS Cooperative, in this installment of the Corn School. “You have to get an idea of what percentage of the… Read More
Several factors converge to increase the threat of diseases on a corn crop, from the history of a disease in the field, to the amount of residue, to the weather. Unfortunately, several corn diseases are carried by wind and can end up in your field whether you practice good rotation practices or not. Related: How… Read More
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
