When it comes to soybeans, research shows the mere presence of weeds cues stress-induced adaptive responses which have a rapid and irreversible negative effect on the yield.
Flea beetles and cutworms in canola
Striped and crucifer flea beetles can cause significant damage in early seeded canola when it is small. Cutworms are equally opportunistic, clipping or severing stems of seedlings before they are strong enough to withstand the damage. Learn how to protect your crop from these three early season pests.
Kochia and agroclimatic factors
If you believe prairie growing conditions will get warmer in future years, and possibly drier too, here’s what that could mean for the spread of kochia.
Kochia is more than tough – it’s almost unfair. It is comfortable growing in cool temperatures and soil, and can emerge weeks before spring-planted crops. Then again, kochia also thrives when hot summer temperatures cause crops like wheat to suffer.
Research reveals viable kochia management strategy
While there’s no silver bullet, certain chemical and cultural practices can manage the worst impacts of this weed and help contain its spread.
Everyone knows that kochia is a challenging weed in Western Canada. It emerges in cool spring soils before crops are even planted. It produces seed prolifically and disperses it widely. Kochia shrugs off dry, hot and saline conditions and thrives when crops struggle. Herbicide resistance takes several useful chemistries out of the toolbox.
Kochia biology and ecology - Why kochia is such a tough customer
Kochia has unique characteristics that allow it to thrive in the southern Prairies. Knowing the weed’s biology and ecology provides the basis for a rigorous defense.

Taking charge of kochia and cleavers in wheat
Control kochia and cleavers early
The number of acres infested with kochia has gone up significantly in the past five years. Some kochia biotypes are even resistant to multiple groups of herbicides (2, 4 &9).
Cleavers is another difficult weed to control. It’s on the rise too as it has spread quickly through the dark brown, black and grey wooded soil zones.
