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…

Even if seeding is two or three weeks away, a pre-seed burnoff now could keep these weeds from getting too big to control. We have reports of gigantic winter annuals in fields where they haven’t been sprayed…

A farmer is seeding Roundup Ready canola and the field has a lot of winter wheat volunteers and some perennials. Is the farmer better to seed or spray first? Answer: In this situation, with Roundup Ready canola being able to take a glyphosate application at any time up to the 6-leaf stage, the farmer may want to take advantage of…

Volunteer canola is a weed and competes with the crop for nutrients and water and sunlight. Volunteers in a canola crop do not make a positive contribution to yield. Growers also have other reasons to get rid of them: Volunteers do not have seed treatment, so they can introduce seedling diseases and increase flea beetle pressure. Also, volunteers in non…

If choosing to seed before spraying, weeds present will have a minimum five days — usually more — before the crop emerges. These weeds can advance very quickly in good conditions, which is why growers who seed before spraying may choose to apply in the narrow post-seeding pre-emergence window…
