Proper staging is critical when applying in-crop herbicides in corn, but there are multiple ways to measure corn’s growth stages, and herbicide labels don’t always use the same method. Agronomists often use the “leaf collar” — or V-stage — method to describe growth stages, while others use plant height. However, herbicide labels often refer to… Read More
Early-season corn scouting requires a little bit of time and attention, but can really pay off for the rest of the year and even into the next. Sara Meidlinger, market development specialist with Pride Seeds for Western Canada, joins Kara Oosterhuis for this Corn School episode. Scout representative areas of the field including good and… Read More
Early planted corn is starting to emerge in Ontario and usually when digging around, a nice straight plant can be seen coming out of the ground. This year, though, a few plants are a little wonky. Down in Lambton County, Ont., agronomist Ryan Benjamins is seeing quite a bit of corkscrewing in corn this year,… Read More
The corn crop is in the ground in Ontario and it’s time to get out and scout. When scouting corn early in the season, diagnosis of issues is key for managing the crop further along in its growth. In this episode of Corn School, Bernard Tobin is joined in the field at Lambton County, Ont.,… Read More
Dry spring planting conditions have many growers wondering how their soil-applied residual herbicides will perform, as the weather continues to heat up with little meaningful rain in sight. Research by University of Guelph weed scientist Dr. Peter Sikkema indicates pre-emergence herbicides will still deliver significant value for growers in dry spring conditions. He notes that… Read More
There’s always plenty of attention paid to getting grain corn off to a great start, and the same principles apply when it comes to the finer points of planting corn for silage. With seed deliveries underway and planting season around the corner, Alana Serhan, market development agronomist for Pride Seeds in Western Canada, takes us… Read More
Precipitation, in both the frozen and liquid form, has been scarce in a large part of the northern corn growing areas of North America, creating the prospect of planting into a possible drought. There are several choices a grower can make to help maximize water use and mitigate drought risk, explains Alana Serhan, market development… Read More
Plenty of things are showing signs of life right about now in Ontario, including the weeds. To determine how to control these yield-robbing plants in the weeks ahead, Bernard Tobin is joined by Rob Miller, agronomist at BASF, in this episode of the Corn School. Typically, a conversation on spring weed control is determined by what… Read More
With help from precision technology, corn growers are fully capable of conducting well-designed, logistically simple field trials that can help improve yield and profitability. When it comes to on-farm research, “that’s the beauty of today versus 30 or 40 years ago when I started in this business,” says Purdue University corn expert Bob Nielsen. On… Read More
One of the keys to a high-yielding corn crop is even, uniform emergence. Growers can achieve this management goal in early-planted April crops when soil conditions are fit, but what happens when the weather turns bad and soil conditions take a turn for the worst at planting? On this episode of Corn School, Ken Currah,… Read More
What’s the secret to growing those gigantic corn yields that turn a select few U.S. farmers into corn yield contest kings? Purdue University corn guru Dr. Bob Nielsen has been pouring over National Corn Yield Contest data and crop input and management summaries from winners for almost two decades. What has he learned? After all… Read More
Corn rootworm, manure, and soybeans — farmers don’t often hear those three words in the same sentence but we’ve come to expect the unexpected in 2020. With growing resistance to corn rootworm traits in Ontario, many farmers who typically plant continuous corn will look to control the pest by expanding rotations to include soybeans. But… Read More
Sixty-inch spacing for corn is sure not for everyone, but the math and soil conservation rewards can work for farmers who have limited rotations and can benefit from extended grazing for livestock on well-established cover crops. That’s Sunderland, Ontario, farmer Ed Hanson’s takeaway from the first year of growing corn in 60-inch rows on his… Read More
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
