Outlook for Steward insecticide in Southeast Arkansas Conference Paper uri icon


  • Steward, a new insecticide with a novel mode of action, was evaluated in 1998 against worms, plant bugs, and boll weevils in addition to its effect on beneficial arthropods. Five separate tests were conducted at the Southeast Research and Experiment Station near Rohwer, AR in which Steward 1.25SC was evaluated at the rates of 0.09 and 0.11 lb ai/ac. Square inspection, sweep net and beat sheet samples in addition to visual rating of foliage damage were used to assess the efficacy of Steward and other insecticides used in this study. Our data show that Steward is an effective control agent against tarnished plant bug and beet armyworm. Tobacco budworm survival trends after treatment strongly indicate that Steward may effectively control tobacco budworm and reduce damage to squares. Adequate assessment of Steward efficacy on bollworm was not possible because of insufficient worm pressure. Increased lint yield was obtained with Steward in some tests, but not in others where insect pressure was not high enough to result in differential damages among treatments. Steward appeared to be soft on predaceous beneficials.
