A few days of summer-like conditions have weeds thriving, taking up nutrients and topsoil moisture. Whether canola is already emerging, seeded but not emerging, or not yet seeded, now is a good time to remove that costly weed competition. Here are some options for each of those three situations…
-
Weeds that emerge before the crop will out-compete the crop for moisture, nutrients and sunlight. That is why just a small number of weeds – even just a few per square foot – emerging before or with the crop can be much more damaging to yield potential than a larger number of weeds flushing later…

Simple but effective... Tank mixes are recommended to control canola volunteers and glyphosate-resistant kochia, and to protect the long-term viability of glyphosate…

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

Three topics: Seed first or spray weeds?; Spraying weeds in cool conditions; Tank mix options for pre-seed burnoff…

Tank mix options for glyphosate ahead of canola are bromoxynil, Aim/CleanStart (carfentrazone), clomazone, Conquer (bromoxynil and carfentrazone) and quinclorac. Tank mixing can prevent herbicide resistance…

Weeds that emerge before the crop can be highly damaging to crop yield potential because they out-compete the crop for moisture, nutrients and sunlight. When the crop emerges, all early weeds need to be dead…

For best results, spray winter annuals when they’re small. They’ll be growing fast this week…

Of all the glyphosate applied in the pre-seed window in Western Canada in 2017, 73% was applied alone. Only 27% was tank mixed. That’s according to data Monsanto presented at meetings this winter. Tank mixing multiple modes of action is generally considered one of the best ways to avoid herbicide-resistance, so we want to see that tank-mixing number grow…
