The Pest Management Regulatory Agency (PMRA) recently approved the registration of Elevore herbicide, a new tool that provides consistent, pre-plant burndown control of glyphosate-resistant Canada fleabane and several other broadleaf weeds, including common ragweed.

“We know that glyphosate-resistant Canada fleabane is one of the top weeds on growers’ minds, as it’s extremely difficult to manage in-crop and herbicide options can be limited,” says Dave Kloppenburg, category leader for row crop herbicides at Corteva Agriscience. “Controlling Canada fleabane with Elevore herbicide as part of a pre-plant burndown program is a good agronomic practice that helps ensure weeds aren’t interfering with your crop.”

Kloppenburg explains that Elevore herbicide contains Arylex active, part of a new family of Group 4 herbicides. Arylex active allows Elevore herbicide to bind tightly to target weeds, providing thorough, systemic control while also eliminating re-growth. “It locks onto the weed and doesn’t let go,” he says.


Kloppenburg recommends that growers use Elevore herbicide in combination with other residual herbicides and modes of action to create a pre-plant weed control program that will help manage against future resistance.

Elevore herbicide can be applied pre-plant with all major corn and soybean production systems, including conventional, Roundup Ready, Enlist and Xtend.

Elevore herbicide will be commercially available in Eastern Canada for the 2019 growing season.

Corteva Agriscience, Agriculture Division of DowDuPont, is intended to become an independent publicly traded company when the spinoff is complete by June 2019. After that date, it will be Corteva Agriscience.
