From seeding rates, to seeding date, crop rotation and more, managing herbicide resistant weeds is about so much more than just what you decide to spray your fields with. That’s because each decision that impacts weed pressure, also impacts weed control, and every time you go over your crops with a herbicide, you’re putting selection… Read More

DuPont Crop Protection has announced the registration of new DuPont Express FX herbicide for pre-seed weed control before planting spring wheat, durum or barley. Express FX delivers two modes of action, Group 2 and Group 4, as an add-in to glyphosate. Tank-mixed with Group 9 glyphosate, that makes three modes of action for “an additional… Read More

Sometimes it’s the little things that go unnoticed that actually have a big impact. Who hasn’t been waylaid by one tiny little part that breaks or goes missing? Big-picture considerations are important too, but the devil, as they say, is in the details. When it comes to spraying, details can easily be overlooked. When’s the… Read More

Consistent droplet size and canopy penetration are two key points of getting the most out of your spray application (assuming you’re after leaf coverage, of course). Sending spray droplets where you actually want them to go is much harder than it sounds — part of the reason for that is air movement and turbulence as… Read More

While research shows fungicide applications in wheat and corn can often be justified by higher yields, the yield response to fungicides in soybeans is not as clear cut. Timing of fungicide application might be part of the formula for getting better than break-even returns, says Dave Hooker, field crop agronomist and assistant professor at the University of… Read More

On-farm efficiency is certainly a hot topic in today’s agricultural climate. But are we getting a little too keen for speed in the sprayer? We’ve heard often the importance of patience while seeding (check out the Canola School on seeding speed/depth from 2013), but sprayers are often exceeding 15mph in the field. This can have detrimental impacts… Read More

How do you make a skinny tire that damages as little crop as possible but doesn’t just cut through soft soil like a knife through butter? The key is having a flexible sidewall that allows the tire’s footprint to expand. “Basically the ability to make the tire as flexible as possible means you can carry a much higher… Read More

The day when unmanned aerial vehicles (UAVs) are used for spraying fields in North America could be here sooner than we expect. In fact, for small acres, that day may have already arrived. Several spraying units made by a Swift Current-based RotorSpray attracted plenty of attention at Farm Forum in Saskatoon earlier this month. The UAVs were… Read More

One of the leading causes of herbicide injury in canola is insufficient sprayer cleaning, says Clark Brenzil, provincial weed control specialist for the Saskatchewan Ministry of Agriculture. Whether due to drift or residue, herbicide injury can result in drastic yield losses, besides being an eye-sore to drive by. Related: Spray Tips with Tom Wolf — Ep. 6: 7 Steps to… Read More

Now that there’s a little more time on our hands, we can look back at the growing season and see where issues and inefficiencies arose. One of the major concerns this year in Western Canada was herbicide injury, especially in canola crops, where some growers thought their Liberty Link canola was seeing injury from its… Read More
