Single and sequential applications of glufosinate provided excellent control of Group 2 and Group 2 + 9 resistant kochia. Treatments containing sulfentrazone (which were experimental and not registered) caused excellent control but unacceptable crop injury. Layering strategies with ethalfluralin and/or carfentrazone followed by glufosinate may...

Research found increases in growing degree days, corn heat units, the number of frost-free  days, and average, maximum and minimum air temperature on the Prairies. Average annual precipitation and growing season precipitation have increased in Canada, but western Canada had increases in some regions and...

Cabbage seedpod weevil continues to expand across the Prairies, contributing to yield losses of 5 to 30%. Insecticidal control remains the main management strategy despite decades of research into alternative biological and cultural methods of control. The cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae), is native to...

The overall Economic Injury Level was found to be around 9 to 23 Lygus bugs per 10 sweeps using $15.47/bu ($682/tonne) canola prices. However, insecticide trials on farmers’ commercial fields found that yield was protected from Lygus feeding with a foliar insecticide application at the...

Starter phosphorus (P) and zinc (Zn) fertilizer increased early-season growth, plant height, P concentration, and uptake of P and Zn in plant tissue, relative to the unfertilized control. In some cases, starter fertilizer reduced days to maturity and grain moisture content. The  largest responses were...

Canola yield increased by up to 40% with increasing N rate up to 134 lbs/ac (150 kg/ha) pre-plant (i.e. close to seeding) application via broadcast or banding. There was no significant difference in yield between pre-plant only N application and a split pre-plant plus top-dress...

Wheat, pea and canola uptake of copper (Cu), zinc (Zn) and boron (B) was greater with optimum soil moisture and warm temperatures compared to drought and saturated soil moisture conditions or cold temperatures. Micronutrient deficiencies can occasionally occur on Prairie soils, but crop response to fertilization...
