Syngenta Canada Inc. has announced the registration of Tavium Plus VaporGrip Technology herbicide for broad-spectrum control of grass and broadleaf weeds in Roundup Ready 2 Xtend soybeans.

Tavium is a pre-mix of dicamba (Group 4) and s-metolachlor (Group 15), the active ingredient in Dual II Magnum herbicide. It can be applied pre-plant or pre-emergence in Roundup Ready 2 Xtend soybeans as part of a two-pass program to control glyphosate-resistant Canada fleabane, giant ragweed, and common ragweed, as well as other target weeds such as lamb’s-quarters, barnyard grass, and foxtail.

“Herbicide-resistant weeds and, in particular, glyphosate-resistant weeds, continue to pose a challenge for soybean growers,” says Joe Vink, product lead for corn and bean herbicides. “Tavium is a new herbicide specifically designed to help manage these resistant weeds in Roundup Ready 2 Xtend soybeans. Compared to stand-alone dicamba products, the dual modes of action in Tavium broaden the activity spectrum resulting in increased efficacy and sustainability in the fight against resistant weeds.”

The Ontario Weed Tour at the Elora Research Station discussed how plant staging accuracy, timing and weather conditions can significantly impact crop health, yield and limit potential herbicide application injury.

In addition to burndown of glyphosate-resistant Canada fleabane and common and giant ragweed, Tavium provides systemic and residual control of Group 2- and triazine-resistant weeds. Tavium is the only dicamba product available in a pre-mix formulation that also offers residual grass control to help soybean fields stay weed-free to the V3 growth stage.

Tavium is available for the 2019 season.
