David Gummert, agronomy center manager for Van Diest Farm Supply in Gilmore City, Iowa, recommends FMC’s Anthem, a combination of pyroxasulfone and fluthiacet-methyl, the active ingredient in FMC’s Cadet, to customers faced with herbicide-resistant waterhemp and severe sunflower and velvetleaf infestations.
No-till corn and soybean grower Paul Sefcik of Ottosen, Iowa, says he knew he had to do something differently when waterhemp began to survive multiple glyphosate applications. “I had planted Roundup Ready corn and soybeans for a long time,” Sefcik says. “The Roundup used to work okay, but after a while the waterhemp was still coming up, even after a third glyphosate application.”
Van Diest’s Gummert says wet weather prevented a spring burndown application on Sefcik’s fields, leading to a planned postemergence treatment at the V4 – V5 stage with 8 ounces per acre of Anthem and 36 ounces per acre of glyphosate. Says Sefcik, “Anthem works really well; I had a nice clean field with no setbacks.”
