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… -
Decisions on what variety, nutrient or crop input product to buy are improved with good data. When looking for data, here are a few clues as to the quality of the data set…

Rain and delayed harvest have caused some cut canola plants to regrow. This regrowth coming up through swaths can make for increased green matter going through the combine. This regrowth cannot be sprayed… -
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… -
Fall is a good time to control perennial and winter annual weeds. The message this week includes two reminders: 1. Wait for post-harvest regrowth. 2. Know the best timing for the weeds present… -
Weed management includes a keen eye for the unusual. “Unusual” can be suspicious patches of common weeds (herbicide resistance?) and presence of new unknown weeds. Jimsonweed is, for many, an usual and unknown weed. (Shown above.) It was reported in several Alberta canola fields a couple weeks ago, and has now been confirmed in fields in 11 Alberta municipalities… -
Verticillium wilt was found in a canola field in Manitoba in 2014, and a survey of approximately 1,000 fields across Canada is underway this summer and fall… -
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…
