New herbicide tackles glyphosate-resistant Canada fleabane

There’s a new tool available for growers in the fight against herbicide-resistant weeds, such as Canada fleabane. Corteva Agriscience has launched Elevore, a Group 4 herbicide option for pre-plant burndown of broadleaf weeds, including glyphosate-resistant Canada fleabane, in both field corn and soybeans. Last week at Canada’s Outdoor Farm Show, Dave Kloppenburg, Corteva’s Canadian category leader… Read more »

Soybean School: A fall plan for tough-to-kill weeds

Pre-harvest is actually a great time to get a handle on tough-to-kill weeds in the soybean crop or ahead of next year’s crop. But fall weed control takes a careful mix of planning, timing, and proper product selection or tank-mixing. For those of you with weed escapes or poor control as a hangover from this… Read more »

Resistance Management School: It’s all about diversity

Herbicide resistance is nothing new to Ontario farmers. It all started in 1973 when triazine-resistant lamb’s-quarters were found on a farm near Ripley, Ontario. Group 2 herbicide-resistant weeds were first documented in 1996. Fast forward to 2018, and we find that the province is now home to a host of glyphosate-resistant weeds including Canada fleabane, giant… Read more »

Fall weed control strategies after an early harvest

If you’re talking early weed control, fall is the earliest you can get for next year’s crop. For many, a pre-harvest glyphosate application does double duty, drying down the crop and setting back those perennials weeds. But in this incredibly dry year, crop dry-down was so fast many farmers didn’t need to use glyphosate pre-harvest,… Read more »

Manage resistance by rotating modes of action

Resistance One of the many things to think about while managing herbicide resistance on your land is the rotation of modes of action. Many growers don’t realize how much Group 14 herbicide they are using. While there are many common add-ins used with glyphosate, more than half of them are from Group 14 — which,… Read more »

Be cautious when buying in hay, says forage specialist

If you’re running low on forage, chances are you might already be starting to look for hay suppliers outside of your area. Terry Kowalchuk, forage specialist for the Saskatchewan Ministry of Agriculture, says you have to be conscious of who you buy from, so that you do not get more than you bargained for. He… Read more »

Xarvio launches weed identification app

What if you could just point your phone at a weed and the phone would tell you what you were looking at? At one time it was a huge breakthrough to be able to take a picture of a weed and send a text message to an agronomist. It still is in fact, but sometimes… Read more »

Avert a spray disaster by using the proper mixing order

What happens when you don’t follow the WALES method for adding pesticide formulations to a tank partially filled with water? You really can plug up a sprayer, fail to take advantage of good spraying conditions, and waste time cleaning up the mess. At the recent Crop Masters tour at Syngenta Canada‘s Honeywood research facility in… Read more »

Will relay intercropping work in Ontario?

RealAgriculture agronomist Peter Johnson is keeping a close eye on relay intercropping trials planted in Ontario this summer. The objective of the research is to evaluate whether Ontario farmers could effectively plant soybeans into standing wheat versus double cropping soybeans that are planted after wheat is harvested. In this video, Johnson inspects an intercropping trial at… Read more »

Chaff deck designed to capture and control weed seeds in combine wheel tracks

Every year at harvest, weed seeds are spread across the field through the back of most combines, setting the stage for weed competition across the entire field. A company in Western Australia has developed a tool to confine those weed seeds to the combine’s wheel tracks. The EMAR Chaff Deck replaces the chaff spreader on… Read more »

Corn School: Will drone sprayers fit your farm?

Is the clock ticking on the future of your ground sprayer? Could it eventually be replaced by a swarm of UAV sprayers that could better target weeds and deliver herbicide to exact locations in the field? These are questions we explore with AGRIS Co-operative agronomist Dale Cowan on this episode of RealAgriculture’s Corn School. Cowan recently… Read more »

Soybean School: Why tackle herbicide resistance with multiple modes of action?

Many agronomists talk about the importance of multiple modes of action when planning a weed control program. In this episode of RealAgriculture’s Soybean School, Ontario Ministry of Agriculture, Food and Rural Affairs weed specialist Mike Cowbrough shows you why. We catch up with Cowbrough as he surveys a patch of Canada fleabane that has survived… Read more »

Soybean School: Scout to evaluate your stand and when to go rolling

What’s your strategy when scouting a newly emerged soybean field? When Agromart Group agronomist Steph Kowalski walks into a soybean field this time of year, the first thing she looks to assess is final emergence and population. “It’s important to know how well we got that seed into the ground,” Kowalski tells RealAgriculture’s Bernard Tobin… Read more »

TechTour: Culti Cam system offers automatic cultivator positioning in row crops

In another move towards automation, Claas has unveiled a system for automatic steering of cultivators in row crops. The Culti Cam uses a high-resolution camera to detect rows, and then adjusts the position of the implement, centring it between rows, independent from the tractor’s steering. Using colour and 3D surface information, Claas says the camera software… Read more »

Group 14 resistant waterhemp confirmed in Ontario

It’s not necessarily the happiest of discoveries, but it’s a first-of-its-kind discovery, nonetheless. Work out of the University of Guelph has confirmed Group 14 resistance in waterhemp at multiple locations in Ontario. What’s more, Dr. Peter Sikkema’s research team, including graduate student Lauren Benoit, has also confirmed waterhemp with cross-resistance to Groups 2, 5, and… Read more »
