Saflufenacil is a new herbicide being developed for broadleaf weed control in several crop and non-crop use patterns. Control of sensitive weed species is through the inhibition of the protoporphyrinogen IX oxidase enzyme. Saflufenacil demonstrates both rapid postemergence activity as well as preemergence activity on sensitive broadleaf weed species. The targeted use pattern in cotton is as a preplant burndown application. Saflufenacil effectively controls a broad spectrum of key broadleaf species including glyphosate or ALS resistant biotypes such as horseweed (Conyza Canadensis), cutleaf eveningprimrose (Oenothera laciniata), ragweed species (Ambrosia spp.), and pigweed species (Amaranthus spp.). Targeted burndown use rates are 18 25 g ai/ha. Applications should be made up to 21 to 28 days prior to planting. Saflufenacil can be tankmixed with 2,4-D or dicamba to complement the broadleaf spectrum, or with glyphosate to increase the burndown spectrum to include grasses.

Key words: Saflufenacil, cotton, preplant burndown, horseweed, cutleaf eveningprimrose, glyphosate resistance
