When it comes to producing seed corn, managing pollination and effectively detasseling the crop are critical steps in maintaining genetic purity and seed quality. To get the job done, seed companies use a combination of technology and old fashioned boots on the ground to remove female tassels to ensure they get the unique hybrids they… Read More

What happens when a soil-applied herbicide application is followed by severe weather? For many herbicides it is business as usual, but in some cases a heavy rain can cause a typically safe product to injure the plant. On this episode of RealAgriculture’s Corn School, Ontario Ministry of Agriculture, Food and Rural Affairs weed specialist Mike… Read More
Can heavy July rains fuel nitrogen leaching and push the valuable nutrient beyond the reach of corn plant roots? That’s a question Ontario Ministry of Agriculture, Food and Rural Affairs corn specialist Ben Rosser has been hearing a lot lately as many areas of the province have been dealt a deluge of rain. On this… Read More
Research has repeatedly shown corn’s yield potential starts declining if plants don’t emerge within a tight timeframe, but dry conditions following planting can wreak havoc on best-laid plans for uniform emergence. If one in six corn plants is two leaf stages behind the rest, expect a four per cent yield reduction, says Morgan Cott, agronomy… Read More
What’s the best strategy for applying fungicide in highly variable corn fields where plants range in maturity from three to 10 leaves? That’s a question BASF agronomist Ken Currah tackles on this episode of the RealAgriculture Corn School. He says that’s been the story of many corn fields this year, especially on clay soils where… Read More
The weeks following planting season — when problems that arose during planting are still top of mind and planter-related issues can be identified in the field — offer an opportunity to pro-actively perform maintenance and upgrades before parking the planter in the back of the shed. The summer months can also coincide with equipment dealer… Read More
It’s been dry and cool in Ontario for most of this spring and those growing conditions impact everything from planting, to weed control, and even nitrogen application. On this episode of the RealAgriculture Corn School, Ontario Ministry of Agriculture, Food and Rural Affairs soil fertility specialist Colin Elgie shares nitrogen strategy tips for growers as… Read More
The proof is in the plant stand when it comes to evaluating how a corn planter performed in spring. This episode of RealAgriculture’s Corn School is all about grading planter performance, as we head to a field near Homewood, Man., with Breanne Rey of PRIDE Seeds and planter expert Andrew Kippen of North Valley Precision… Read More
A bag of seed corn checks in at 80,000 kernels and typically weighs between 35 and 65 pounds. One bag will plant roughly 2.5 acres. But the job of producing that seed is very different than growing a commercial corn crop. On this episode of RealAgriculture’s Corn School, we kick off a three-part series on… Read More
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
