A tough fall, winterkill, and a cool, wet spring are adding up to a condensed and busy herbicide application window for growers across Ontario.One of the first challenges is how to manage best all the abandoned winter wheat acres that are likely to be planted as corn or soybeans. On this episode of the RealAgriculture… Read More
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
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
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
For all the talk of a late, late spring, we sure have caught up in a hurry. While there are areas hurting for moisture nearly across Canada, some regions have had near-ideal planting conditions and even a timely rain or two, post-seeding. What’s got croppers curious this week? Peter Johnson, host of Wheat Pete’s Word,… Read More
Are we doing enough to reduce the herbicide-resistance weed seedbank on Ontario farms? That’s a question AGRIS Co-operative agronomist Dale Cowan wants farmers in the province to consider when they’re planning their weed control programs for this year. Cowan recently attended the Commodity Classic in Anaheim, California, where he talked with farmers from Mississippi who… Read More
With fields drying out and warming up soybean planting is moving full steam ahead in Ontario. In many cases the spring conditions are dictating that farmers take a ‘plant now, spray later’ approach. It’s an obvious choice, but the challenge for many is how to manage fast-growing, large weeds that can quickly take a bite out… Read More
The nitrogen is on, the wheat and weeds are growing, and field work and planting is beginning in earnest in Ontario’s south (other areas and much of Western Canada will just have to wait a tiny bit longer). As #plant17 gets rolling, Peter Johnson is back with another edition of Wheat Pete’s Word, and this… Read More
Harvest season is well underway for the earlier crops, and this challenging 2015 growing season shows no signs of easing up as farmers are looking at their harvest management options in weedy or too-green crops. The oat crop is coming off boasting tremendous yields, but wow is it work to get this crop harvested, says… Read More
It’s been a tough few years for winter wheat in Ontario, not necessarily because of the summer season, but because of the late and wet falls farmers have struggled with for the last two seasons. The fallout from a rough harvest is two-fold when it comes to winter wheat — the crop gets put in… Read More
If you’ve noticed more than a few fleabane “escapes” in recent years, you’re not alone. Glyphosate resistant Canada fleabane has spread across more than 700 kilometers of Ontario crop land in just five years. Despite its incredible distribution, Canada fleabane wasn’t the first glyphosate resistant weed found in Ontario, says Dr. Peter Sikkema, field crop… Read More
There’s no shortage of heartache or questions stemming from last week’s extreme frost event across much of Ontario’s growing region. Temps dropped as low as -8 degrees C, if you can believe it, and it wasn’t just corn and soybean crops hit hard by the cold weather — tender fruit, horticulture and vegetable crops have… Read More
Glyphosate resistant fleabane is coming to a field near you, of that you can be sure. Truth is, you may already have it in your fields, and if you’re typically waiting until spring to control it, the problem is only going to get worse. But take heart! There are options for fall control that can… Read More
There are at least two reasons why having an added herbicide tolerance gene built-in to a soybean variety makes sense — one, to make up for early season non-competitiveness of the crop, and, two, because of the increasing risk of glyphosate-tolerant weeds. To that end, Monsanto recently rolled out its soybean XTend trait — dicamba… Read More
Farmers do a great job of in-crop weed control, which is great, seeing as weeds competing with the crop for nutrients and sunlight steal from yield. That said, a recent survey suggests that farmers are missing a key window of time for weed control — the four-week window after winter wheat harvest — that could… Read More
