New herbicide tackles glyphosate-resistant Canada fleabane

There’s a new tool available for growers in the fight against herbicide-resistant weeds, such as Canada fleabane.

Corteva Agriscience has launched Elevore, a Group 4 herbicide option for pre-plant burndown of broadleaf weeds, including glyphosate-resistant Canada fleabane, in both field corn and soybeans.

Last week at Canada’s Outdoor Farm Show, Dave Kloppenburg, Corteva’s Canadian category leader for corn and soybean herbicides, explained that the new herbicide will control Group 2 and 9 resistant Canada fleabane and common ragweed. He believes it will be a key tool for Ontario growers as they tussle with increasing herbicide resistance.

Kloppenburg says combining multiple modes of effective action against resistant weeds is the best control strategy and growers should consider adding Elevore to their spray tank. The herbicide can be used as a pre-plant burndown in the spring when weeds are actively growing. Recommended application timing is five days before field corn planting and seven days before soybean planting.
