Herbicide “layering” strategy delivers multiple punches

Effective for weed control and reduces risk of herbicide resistant weeds surviving

By
Corey Loessin has for several years been delivering the one/two and sometimes multiple punches through the pulse crop weed control program on his northwest Saskatchewan farm. Primarily growing red lentils and yellow peas near Radisson, northwest of Saskatoon, Loessin says his main objective is to use different products with varying modes of action to control […] Read more

Post-harvest weed control applications

Q & A with Nutrien Ag Solutions

By
Q. What weeds should I target in post-harvest weed control applications? A. Two general weed groupings can be effectively controlled with a post-harvest herbicide application. Perennials: Controlling perennial weeds such as Canada thistle, dandelions, foxtail barley and quackgrass involves an integrated plan, and a post-harvest herbicide application that includes glyphosate is a pivotal part of […] Read more
From left to right, these photos show plots were the water hardness is 120 ppm, 400 ppm, then 1200 ppm. Glyphosate has been applied at 2/3 of label rate. Water hardness can take the edge off weed control.

Les Henry: Water quality and herbicides

You know your herbicides. But what’s in the other 999 gallons you put in the tank?

By
As we gear up to fill the sprayer and begin killing weeds maybe we should take another look at what is in the other 999 gallons in the sprayer. It is well known that the water should be clean with no silt or debris present, but this piece deals with the dissolved “goodies” you cannot […] Read more

Manage herbicide resistance before you have it

Try a wide variety of 
weed control strategies

On BASF’s 2019 Herbicide Resistance Management Webinar in March, Andrew Reid, BASF technical service specialist, said it’s always easier to manage herbicide resistant weeds before you have them in your field. One way to do this is to keep things clean. “Cleanliness is key,” Reid said. For example, if you don’t clean your combine after […] Read more

Good to be mixed up, in the right order

The sequence of the herbicide tank mix matters. Get it right with W.A.L.E.S

By
With more interest in recent years in tank mixing different herbicide products to provide more effective control of weeds, and reduce the risk of selecting weeds for herbicide tolerance, producers need to follow the proper mixing procedure. It’s not just a matter of which products can be safely tank mixed, but also what order different […] Read more

Managing Saskatchewan’s toughest weeds

You’ve seen these weeds before, and you’ll probably see them again


By
No matter which crops Saskatchewan farmers grow, the same weeds appear year after year. While the culprits are consistent, how you manage them is not, especially as herbicide resistance cases mount. For nearly 50 years, Canada thistle, wild oats, wild buckwheat and green foxtail have appeared in the top-five list of problematic weeds in Saskatchewan. […] Read more

Crop advisor casebook: Is a local lack of moisture injuring this barley?

A Crop Advisor's Solution from the April 9, 2019 issue of Grainews

By
John contacted me in late May last year about his barley crop. The plants were coming up yellow in patches across the field. John farms about 2,800 acres near Whitewood, Sask., where he grows wheat, barley, canola and soybeans. It had been a dry spring and John thought environmental stress due to lack of moisture had caused the plant injury. […] Read more

Check your soil for herbicide residue

Learn how to conduct plant bioassays to detect potential herbicide residues in your soil

By
Plant bioassays are a simple, inexpensive, accurate and direct method of determining if it is safe to grow crops on land previously treated with known herbicides or on cropland or compost with an unknown history of herbicide use. A bioassay can detect if herbicide or chemical residues are present in the soil or compost at […] Read more

Controlling volunteer canola in soybeans

New research in Manitoba finds fall tillage can reduce the volunteer canola seed bank

By
Volunteer canola is difficult to control in soybean because the two crops are often resistant to the same herbicides, leaving few chemical control options available to growers in Western Canada. That causes more than a few headaches for soybean growers, especially as research shows that Prairie canola seed harvest losses on average are around six […] Read more

Get back to basics to fight kochia

Using multiple and rotating modes of action can reduce selection pressure

By
In recent years, kochia has become a real issue across the Prairies. Kochia loves hot, dry weather, and as a prolific seed producer, the tumbleweed-shaped weed can spread quickly. What’s worse, kochia has a growing history of resistance, which can make it a tricky weed to manage. Agriculture and Agri-Food Canada research scientist Charles Geddes […] Read more
