DuPont Canada his picked up registration for its Group 2 broadleaf weed killer Express SG for pre-seed burnoffs before seeding pulse crops.
The chemical company announced Friday that Express has been approved for application 24 hours before seeding field peas, dry beans, fababeans, lupins and soybeans.
The approval gives farmers “a better alternative than glyphosate alone to clean up tough weeds in their fields before seeding,” said cereals and oilseeds product manager Travis Schoonbaert in the company’s news release.
DuPont markets Express SG, a tribenuron methyl herbicide, as a boost for glyphosate in controlling weeds such as dandelion, narrow-leaved hawk’s-beard, flixweed and both conventional and Roundup Ready volunteer canola.

U.S. grains: Corn rebounds from contract lows on short covering, bargain buying
Bargain buying and short covering lifted U.S. corn futures on Monday after the market slid to contract lows on expectations for strong U.S. output, traders said.
The product’s label previously covered its use on the Prairies for pre-seeding burnoff, also 24 hours before seeding spring wheat, durum or barley, and for use on summerfallow. Canola, flax, lentils or alfalfa can be seeded on treated fields two months after application.
The company cautioned in its release that Express SG “is not a fit for
every field” and that farmers should avoid its use in “coarse-textured”
soils of less than three per cent organic matter, or where fields have varying soils,
gravelly or sandy areas or eroded knolls.
