Weed Control in Durum Wheat

Good herbicide selection in durum wheat helps maximize yield.

One of the first ways to achieve high yields in durum wheat is to seed the crop into a clean seedbed to reduce competition for moisture and nutrients. Broadleaf weeds that emerge prior to the wheat crop can cause significant yield loss. They can be even more costly than second flushes that emerge after the crop.

Many growers use only glyphosate for a post-harvest or pre-seed burn-down. However, chances are that there will be weeds like dandelion or narrow-leaved hawk’s-beard that just aren’t well controlled by glyphosate alone. That’s why you should consider adding DuPont™ Express® herbicide to your glyphosate. With Express® PRO, you’ll get about 15 days of extended control (depending on environmental conditions) and can seed durum wheat 24 hours after application. Another great option is to use Express® FX with your glyphosate, which offers 2 different modes of action built-in (2 & 4) for an additional level of resistance management, particularly in areas with resistant kochia.

In-crop weed control

There are multiple solutions for in-crop weed control in durum wheat.  For instance, DuPont™ Barricade® II herbicide set a new standard for control of cleavers and kochia when it was launched. With its wide window of application from 2-leaf up until flag leaf, Barricade® II is an excellent choice for control of tough weeds while still being gentle on your durum.

DuPont™ Predicade™ is an excellent option if you want to control grass and broadleaf weeds in one pass. With two (2) different broadleaf groups (Group 2 and Group 4) as well as a premium Group 2 grass herbicide thiencarbazone, Predicade™ is an efficient and effective way to control tough weeds in durum including kochia, cleavers, wild oats and green foxtail.

Weed control in rotational crops

Sometimes it makes more sense to control grassy weeds in the previous crop, especially a hard-to-kill weed like foxtail barley. DuPont™ Assure® II herbicide offers control not only of foxtail barley, but also Japanese brome and Downey brome, giving producers in Western Canada an excellent way to manage these widespread weeds. Assure® II is an excellent in-crop solution for canola, flax, and pulse crops, providing 99 per cent control of foxtail barley, according to Agriculture and Agri-Food Canada (AAFC) research from Lethbridge. That allows growers to seed into cleaner fields when wheat comes up in the rotation.
