Protecting yield potential from northern corn leaf blight (NCLB) and a newer pest, tar spot, requires being well-armed and ready to apply the right fungicides at the right time. That’s because these diseases are not only big yield robbers, but the window to provide adequate control is quite narrow, and gets narrower with certain weather… Read More

Corn growers often turn to tissue testing to diagnose a problem. When plants in a field are yellowing or pale, grabbing a sample and sending it to the lab can seem an obvious way to confirm a nutrient deficiency. But there’s more to the tissue testing story than simply identifying a problem and finding a… Read More
The race is on for many corn growers as they hustle to apply post-emergent herbicides to control yield-robbing weeds. The duration of the post-emergence application window depends on the herbicide. A product like glyphosate can be applied all the way up to the 8-leaf stage. But other herbicides have tighter timing and need to be… Read More
When it comes to corn, even emergence and uniform plant growth is a well-known recipe for a high-yielding crop. New research also shows that even emergence is a significant contributor in the fight against gibberella ear rot and deoxynivalenol (DON) accumulation and other mycotoxins associated with the disease. On this episode of RealAgriculture’s Corn School, University… Read More
Not all glufosinate ammonium herbicide formulations are the same. This is especially important to note in areas that grow both glufosinate-tolerant (aka LibertyLink) corn and canola. A corn grower in Ontario, or in the Midwest U.S., who orders Liberty or glufosinate from a retailer would likely receive a formulation containing 200g of active ingredient per… Read More
Tillage can play an effective role in warming and preparing soil for planting. When it comes to weed control, however, there are limitations and growers need to have a plan in place to tackle weeds that escape uprooting by cultivators, or those tenacious plants that manage to re-root and grow on to steal yield. On… Read More
As warmer weather arrives and fields start to dry up, many growers are tempted to begin field work in preparation for planting. Working soil that’s not fit, however, can prove problematic later in the spring and throughout the growing season. On this episode of RealAgriculture’s Corn School, we catch up with PRIDE Seeds agronomist Matt… Read More
After a methodical march north from the Corn Belt, tar spot has now gained a foothold in Ontario. Last year, the yield-robbing leaf disease was confirmed in five counties in the southwestern, stretching from Essex to Simcoe. Characterized by tar-like speckling on the upper surface of corn leaves, the fungal pathogen has been delivering yield… Read More
2021 was a big year for corn yield in Ontario. Although not official, the average yield is expected to check in at just over 200 bu/ac — a new record. On this episode of RealAgriculture’s Corn School, we take a closer look at where this yield is coming from with Purdue University agronomy professor Dr…. Read More
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
