Resistance to glyphosate has not officially been confirmed in Canada fleabane populations in Western Canada, but the weed, sometimes called horseweed or marestail, should be on the radar when it comes to herbicide resistance on the Prairies, according to Manitoba Agriculture’s weed specialist. Canada fleabane that’s resistant to glyphosate and other chemistries is already established… Read More

It’s mid-May, but you almost wouldn’t know it by looking at seeding progress in Manitoba and parts of Saskatchewan. Super-dry Alberta and suddenly-warm Ontario bookend the seeding and planting progress and average things out (what does average really tell us, anyway?). On this episode of Wheat Pete’s Word, host Peter Johnson brings us up to… Read More
A cool, wet spring has slowed fieldwork and dreams of early planting appear to be disappearing as the calendar turns to May. But the backward conditions have not stalled weed growth in fields across Ontario. That means growers will need to keep a close eye on winter annuals and mounting weed pressure in soybean and corn… Read More
The annual Ontario field crop diagnostic days held at Ridgetown, Elora, and Winchester will again go virtual in 2021. The organizing committees of these three highly successful in-field education and learning events are again partnering with crop researchers and extension, along with support from RealAgriculture and a host of sponsors to bring you a series… Read More
Corteva Agriscience and BASF Canada Agricultural Solutions (BASF) have announced a collaboration and joint approach to weed control by recommending the combined use of Liberty 200 SN and Enlist herbicides on Enlist E3TM soybean acres. The combination will work especially well on weeds like waterhemp and Canada fleabane, that are now glyphosate resistant in many… Read More
Start clean, stay clean is the motto when it comes to weed control. Super dry conditions, however, can throw a wrench in the best laid plans, as soil-applied herbicides may be less effective and timing a first pass is tricker as weeds are slow to emerge. To discuss per-emerge and early season weed control on… Read More
Do you need to manage herbicide-resistant weeds? Could you use more flexibility during the busy planting season? Does heavy weed pressure make it difficult to keep fields clean early in the season? These are all questions growers should be asking as they plan their 2021 soybean weed control programs, says BASF technical development manager Rob… Read More
It’s time for Day 3 of the virtual Ontario Diagnostic Days! This week, we’re joined by Dr. Peter Sikkema with the University of Guelph, and Mike Cowbrough, weed specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs. This episode focuses on weed management, specifically on glyphosate resistant Canada fleabane and waterhemp, and the… Read More
From microwave ovens, to X-rays, and even potato chips, many important discoveries have been stumbled upon by accident. The same may to be true when it comes to weed control and the continuing fight to control glyphosate-resistant Canada fleabane. On this episode of RealAgriculture’s Soybean School, Mike Cowbrough, Ontario Ministry of Agriculture, Food and Rural… Read More
If you’ve ever adopted a new way of doing things after attending a field day or conference, do you let the researcher or extension staff know? Sometimes, research can be a rather thankless job, and many researchers don’t hear back on their work being applied on-farm. Peter “Wheat Pete” Johnson came across just such an… Read More
Is 2019 the year of the weird? Maybe, says host Peter ‘Wheat Pete’ Johnson in this episode of Wheat Pete’s Word. From planting conditions, to strange looking plants, and on to excessive and strange insect and creepy crawlies — this growing season is nothing short of odd. Johnson tackles what’s going on with things like… Read More
It’d be fantastic if this Wheat Pete’s Word update included a milestone planting progress update, but 2019 is proving to be a slow one for much of Ontario. And while Western Canada is having much more luck getting the crop in, areas are still dry to very dry. Questions submitted for this week’s show involve… Read More
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
