Fall quackgrass growth.

Pre- and post-harvest weed control

Q & A with CPS

Q: When should I start weed control for my crop? A: A weed-free crop at harvest represents the cumulative effort of field management during the season. To manage many weed species, the season begins the previous fall. Pre-harvest weed control tends to focus glyphosate application on perennial weeds such as quackgrass or Canada thistle. At […] Read more

Established chemistry increases weed control options in specialty crop

Will Van Roessel may be reducing hemp acres on his southern Alberta farm this year, reflecting market signals over increasing world production, but he will be using Edge herbicide to help control pre-emergent weeds. Van Roessel who along with family members operates Specialty Seeds near Bow Island, just west of Medicine Hat, says Edge is […] Read more


Weed specialist Clark Brenzil says that ideally wild buckwheat should be controlled at the four-leaf stage or smaller.

Wild buckwheat: A weed to watch

Glyphosate alone is just not enough. 
Why is buckwheat so hard to control?

Wild buckwheat consistently ranks among the top five problematic weeds in Saskatchewan weed surveys. Clark Brenzil, provincial weed control specialist at Saskatchewan’s Ministry of Agriculture, explains what makes this weed so tricky. Wild buckwheat is an annual weed found in cropland in the southern Prairies. Despite farmers’ best efforts, the weed is hardy and persistent […] Read more

Choosing that pre-seed herbicide

Choosing that pre-seed herbicide

Q & A with CPS

Q: What are some considerations when selecting a pre-seed herbicide application? A: There are significant benefits to applying herbicides prior to seeding or crop emergence. Pre-seed weed removal reduces competition for valuable moisture and nutrients required for seedling development. When selecting pre-seed herbicides, begin with the crop to be grown. Products available vary considerably by […] Read more


Because it’s a new weed, probably the first thing growers will notice is stray weeds sitting above the crop canopy.

Managing herbicide-resistant waterhemp in Manitoba

The weed’s movement into Manitoba calls for more vigilant field scouting

Waterhemp was found for the first time in Manitoba in 2016, southeast of Winnipeg in the area around the RM of Taché. The discovery led to the establishment of a waterhemp surveillance program led by Manitoba Agriculture in 2017. More waterhemp was found at a second site closer to the U.S. border. In both circumstances, […] Read more

The best time to deal with a weed such as kochia is when it's small.

In-crop mechanical weed control

Controlling weeds mechanically can help overcome Group 2 resistant weeds in pulses

Group 2 resistant weeds are an annual problem for lentil producers. But there are a few outside-the-box methods that may give farmers better control than herbicide alone. University of Saskatchewan grad student Alex Alba led a study looking at three in-crop mechanical weed control methods, including: Tine harrows; Rotary hoe; and, Inter-row tillage. Alba used […] Read more


6 strategies to manage weeds in pulse crops

6 strategies to manage weeds in pulse crops

From tillage to pre-seed and pre-emergent herbicide applications in pulses

Pulse crop growers face unique challenges in terms of managing weed populations in their crop. Not only are pulse crops less competitive, there are limited choices for pre-seed and in-crop herbicide applications, compared to canola and corn. Plan ahead to manage weed populations and resistance using the tools available. There are many choices for grassy […] Read more

Dealing with dicamba

Dealing with dicamba

At CropSphere in Saskatoon in January, Tom Wolf warned that dicamba can cause issues with sensitive crops — whether due to sprayer cleanout issues or from drift. We’d better be prepared to deal with it, since we’re going to be seeing it more often. Monsanto’s Roundup Ready 2 Xtend soybeans are resistant to both glyphosate […] Read more

Managing herbicide resistance

Managing herbicide resistance

Gowan Canada will host a speaker series 
on Wednesday and Thursday at Ag in Motion

Diversity is defined in the dictionary as “the condition of having or being composed of differing elements.” In weed control, diversity means using multiple strategies, or an integrated weed management approach. For herbicides, this means using all of the modes of action available to reduce the risk of weed resistance. This may be obvious, but […] Read more
