Farm gets aggressive on wall-to-wall resistant wild oats

Agronomist says managing herbicide-resistant weeds is like starting a fitness routine: make a plan, set goals, stick with it

Beating herbicide-resistant weed populations means making a plan with clear goals and objectives and staying on top of it — and that means not allowing weeds any opportunity to set seed in big numbers.

How farmers can help map, monitor and forecast pest outbreaks

Researchers can help producers develop pest management plans — but farmers’ help is needed to know which pests are where, and how many

Prairie scientists conducting research into field crop pests can always use more help from producers — whether it’s by granting access to farmland, or just by reporting what they see in the field.

A Japanese firm’s new chemical isn’t like the other PPO inhibitors

Not yet registered in either Canada or the U.S., the Japanese active ingredient-in-waiting could be needed sooner than later, because many growers in Saskatchewan and Alberta are struggling with herbicide-resistant kochia.

Grow forages, starve weeds

Forages disrupt weed routines and slow herbicide resistance — if you can use them

“Forages actually can be used to combat resistant weeds,” Kim Brown says. “A perennial forage stand will last for several years, but in a spring annual crop rotation, you’re dealing almost exclusively with annual crops most of the time.”

Concerned over canola? Focus on agronomy

In a stressful market environment, best practices can reduce risk and drive profit

The best option for canola producers in the current market environment may be to apply agronomy practices that can improve profits for little to no added cost, the Canola Council of Canada says.

Science Brief: Combining harvest weed seed control with early-maturing crops may limit wild oat populations

Breanne Tidemann has led several research projects looking at whether harvest weed seed control can effectively control weeds. She’s found that combining harvest weed seed control with early-maturing crops may limit wild oat populations, and may lengthen the effectiveness of available herbicides. Harvest weed seed control, developed in Australia, uses equipment such as the Harrington […] Read more

Kochia’s expanding herbicide resistance puts pressure on no-till systems 

Kochia populations in Saskatchewan and North Dakota are now resistant to group 14 herbicides, leaving fewer options for Prairie farmers

Based on preliminary data from a recent Prairie-wide kochia survey, AAFC’s Charles Geddes suspects Group 14-resistant kochia is now present in multiple fields in Saskatchewan and expects it could soon be confirmed in other regions as well.
