“We’re very excited about the launch of our new Sulfentrazone 4F herbicide,” noted Jan Stechmann, President of Helm Agro U.S. “In addition to its broad-spectrum activity, Sulfentrazone 4F offers growers many important benefits. It’s highly effective against ALS-resistant weeds, such as kochia and Russian thistle, plus it can be applied pre-plant or pre-emergence in any tillage system. Furthermore, Helm Sulfentrazone 4F gives growers the flexibility to apply it by ground, air or through sprinkler irrigation systems.”
