Most products are not strongly affected by dust, but glyphosate is an exception. What about wind? Or cold?…

With herbicide applications winding down, this is a good time to scan fields for suspicious weeds that escaped the management effort. The photo from Tammy Jones shows glyphosate-resistant kochia… -
Too windy. Too wet. Sometimes both. This pushed back a lot of weed management and some fields are still not sprayed. In this situation, intense weed pressure can reduce yields by 20%, 30%, 50%... That's why early weed control has a huge positive effect on profitability, but late control is better than nothing. Late control can stop the yield loss,…

A second application of in-crop herbicide is not always economical if the crop is well established, competitive and ahead of the remaining weed population. A second in-crop spray only makes sense if… -
One of our Alberta agronomy specialists encountered the situation in the photo. Canola emergence was patchy in this small area, but generally good overall. The bigger issue was the big population of tiny weeds. The agronomy specialist wondered if these buckwheat seedlings, though very abundant, were too small to spray? The answer is no… -
In general, early is the best for herbicide timing. A few early weeds emerging before or at the same time as canola plants are much more damaging to yield than…… -
A Canola Watch reader sent us this question: I have wild buckwheat at the 3- to 4-leaf stage that somehow got missed with the first application of Liberty 10 days ago . It's moderate in severity. Will it cause me grief at swath timing? And or will it have any effect on yield? Crop stage is 6-leaf or so… -
