Devil's-claw (Proboscidea louisianica) is an increasing weed problem that is not controlled by standard preplant or pre-emergence cotton herbicides. Field experiments were conducted in 1997 and 1998 at the Texas Agricultural Experiment Station near Lubbock to evaluate Staple herbicide for devil's-claw control. Preemergence (PE) applications of Staple alone or in combination with Caparol or Karmex were compared to commercial standard herbicides including Caparol, Karmex, Cotoran, and Caparol + Zorial for devil's-claw control. PE combinations of Staple + Caparol or Staple + Karmex followed by (fb) Staple applied postemergence topical (PT) were compared to preemergence treatments alone. In both years, all plots received a preplant incorporated treatment of Treflan at 0.75 lb ai/A. Plots were four rows x thirty ft long, with three replications arranged in a randomized block design. PE treatments were applied immediately after planting and PT treatments were applied to weeds 2-3 inches tall. All treatments were applied to 10 gpa and crop oil concentrate was added to all Staple PT treatments.
