The Environmental Protection Agency has approved the registration of DuPont Canopy herbicide for pre-emergence use in soybeans.

Canopy provides effective broad-spectrum weed control with early-season residual activity, which allows growers more flexibility in timing their postemergence glyphosate treatments.

“There is an increasing need for a pre-emergence partner with residual for glyphosate weed-control programs,” said Jeff Carpenter, product manager for DuPont Crop Protection. “Canopy herbicide gives soybean growers the flexibility to make their burndown application in the spring and then time their glyphosate application closer to canopy stage, when it can be the most efficient.”

The residual weed control in Canopy helps manage early-season weed competition for maximum yield potential. Carpenter said these benefits can be critical, especially in years when wet weather conditions may prevent a timely glyphosate application.

“Canopy delivers consistent burndown of winter annuals, even under cool, wet conditions,” Carpenter said. “That's going to give growers more confidence about having a clean seedbed to plant into and help prevent regrowth of treated weeds, even when it's been too rainy and cold to get in the field with a glyphosate treatment. It also has two modes of action to help farmers deal with weed shifts and tolerance weed management.”

With its two modes of action, Canopy controls more than 30 broadleaf weed species, including several that are ALS- or triazine-resistant. It also provides partial control of nearly a dozen other weed species.

“The Canopy name has a long track record of effective, consistent weed control,” added Carpenter. “Growers now can turn to a name they have relied on for burndown and added residual weed coverage in glyphosate-tolerant soybeans.”
