Fall weed management in canola

If you have time for fall weed control in canola fields, make the most of it

By
Canola is one of the higher value crops in Western Canada, but returns can be negatively impacted by poor weed control. Luckily, there are options for glyphosate-tolerant canola. Controlling weeds in the fall ensures that the crop suffers next to no yield loss due to competition in the following year. If pre-harvest control isn’t possible, […] Read more

Two good reasons for pre-harvest herbicide

Pre-harvest application can give you better weed control 
and simplify harvest. But know the residue rules


By
Farming decisions always seem to come back to economics, and whether to do a pre-harvest treatment for perennial weed control or harvest management is no exception. But there are many other considerations such as crop type, geographic location, weather and even trade risks that contribute to that decision, says Clark Brenzil, provincial weed specialist with […] Read more

Fighting herbicide resistant weeds with change

Multiple modes of action and stacked seed traits help farmers manage resistance

By
When it comes to herbicide resistance, chemical companies are focusing on multiple modes of action. More varieties with stacked herbicide-tolerant traits are also on the horizon. But as western Canadian farmers sail towards that new future, they should keep in mind management goes hand-in-hand with technology. Stacked herbicide-tolerant traits are a new tool, giving farmers […] Read more

Mulch-based weed control

Using mulch as a weed control strategy isn’t just for organic growers anymore

By
As conventional farmers search for a wider variety of tools to control hard-to-kill weeds, a Manitoba research has found that mulches may help. Martin Entz, a researcher at the University of Manitoba’s Plant Sciences Department, has led or participated in several recent studies of weed control through the use of mulch. “One of the first […] Read more

The 4Rs of wild oat control

Agronomy tips... from the field

By ,
You might have heard about the 4Rs of nutrient management: applying the right product at the right rate at the right time and in the right place. Now, we can take those same concepts and apply them to a wild oat program. First — the right product. Look at whether you’re dealing with a light […] Read more

Canola rotations are key

Recommended crop rotations lower inoculum levels and risk of disease

By
Crop rotation is of utmost importance to manage residue and soil-borne diseases, and many insect species,” says Randy Kutcher, cereal and flax pathologist, University of Saskatchewan. Knowing this, it’s surprising that many growers still don’t heed rotation recommendations, especially with the potential for devastating diseases like blackleg. Blackleg is a residue-borne disease, he explains. “Residues […] Read more

Weed management in soybeans

With high seed prices, farmers will be tempted to lower soybean seeding rates

By
Soybean farmers have been facing a growing threat to their bottom line: rising seed costs. Seeds for the very popular glyphosate resistant cultivars have increased in price by $47.75 an hectare (or 230 per cent) since they were first introduced in 1996. This trend is likely to continue given soon-to-be-introduced varieties with new herbicide resistant […] Read more

Avoiding herbicide resistance

Worried weed scientists gather to discuss the future of weed control without new chemistry

By
The loss of glyphosate is something that we should all lament,” said Steven Powles, director of Australia’s Herbicide Resistance Initiative. Powles compared the importance of glyphosate to penicillin, calling it a one-in-100 year herbicide. Powles was speaking to a gathering of weed scientists at the Weed Science Society of America’s second herbicide resistance summit in […] Read more

New nitrogen stabilizer and herbicide system for crops

Dow AgroSciences is bringing products to market this fall that are more than just “new and improved”

By
Dow AgroSciences does have improved chemistry for weed control in wheat and barley, but along with that it is also introducing a whole new weed control system that includes ramped up genetics in corn and soybeans to improve weed control options in those crops. Along with that, DAS is introducing new-to-Canada nitrogen stabilizers that will […] Read more

Drying with desiccants in pulse crops

Desiccants can simplify pulse crop harvest and weed control, 
but make sure to read the label and know your MRLs

By
Given this year’s cool, wet spring, harvesting in a timely fashion might become a challenge. In pulse crops, desiccant use can be a critical component of harvest management to dry down any remaining green material in the field as well as deal with actively growing weeds. Dale Risula, Saskatchewan’s provincial special crops specialist, starts almost […] Read more
