When freezing temperatures stop fall weed control plans, snow is likely more of a help than a hindrance with respect to overall weed condition. The snow layer is likely to insulate the weed leaf material from the colder conditions that follow it. That could mean you’re back spraying earlier than you would be with frost alone. Spray decisions — when…

Fall is a good time to control perennial and winter annual weeds, but spraying immediately after harvest may not provide the best results. Perennial weeds cut off at harvest need time to accumulate new leaf tissue to absorb herbicides. Four weeks is a minimum recommendation and six weeks is ideal…

Canola is sensitive to carryover from many herbicides. Here’s the list of products that could be used this fall on fields planned for canola next spring, but read the notes carefully…

Fall is a good time to control perennial and winter annual weeds, but...(1) Wait for post-harvest regrowth and (2) Know the best timing for the weeds present… -
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…
