Weed control challenge

When it comes to managing glyphosate-resistant weeds, good isn’t good enough anymore. Soybean growers need exceptional weed control right from the start for herbicide-tolerant and Roundup Ready® crops. And that control needs to continue all season long on the toughest resistant weeds including fleabane, pigweed and ragweed.

Nufarm solution

Two active ingredients (Group 5 and 14) work together to provide strong residual control and sound resistance management. This proven combination controls the toughest resistant broadleaf weeds with bonus activity on hard-to-control annual grasses.
