Pre-harvest is a good time to dry down weeds to make straight combining go more smoothly. A pre-harvest application can also provide some weed control on late growing weeds — but is often too late to stop seed production… -
While it’s too late to spray effectively, growers and agronomists can check fields for the presence and population of winter annual weeds before the snow flies. This information can help with spring pre-seed burnoff and crop rotation planning… -
Western Canada has made great strides in adopting minimum tillage practices that save time and diesel fuel, improve soils and improve sustainability scores. Here are factors to consider before choosing the tillage option… -
The first step in canola volunteer management is to do nothing. Leaving seeds undisturbed so they germinate in the fall or get eaten by birds and insects is a good way to reduce the volunteer seedbank. Canola seeds that remain on the soil surface when the snow flies will deteriorate over the winter… -

While swathing or straight combining, keep an eye out for weed escapes. Unless they are an obvious sprayer miss or are weeds not well controlled under the herbicides used on the field, they could be herbicide resistant weed patches…

Lower temperatures and shortened days in the fall trigger perennials such as Canada thistle, dandelion and quack grass to start moving sugars to below-ground tissues. Winter annuals and biennials are also doing this, but they don’t need a cool temperature trigger. Spraying these weeds in fall takes advantage of this downward flow, providing better control for next year. Read more… -
