Steward™ insecticide, indoxacarb, is a new and novel insecticide from DuPont Agricultural Products. Indoxacarb is from the oxadiazine class of chemistry. Steward™ has been evaluated in western cotton for 7 years (1993-1999). In Arizona and California studies, Steward™ has consistently provided effective knockdown and residual control of beet armyworm and cabbage looper larvae in Bt and non-Bt varieties. Steward™ has also exhibited short term (2-6 days) suppression of Lygus bugs, particularly nymphs. Steward™ appears to have several advantages over older lepidopteran insecticides such as Lannate^®, Lock-On^®/Lorsban^® and pyrethroids in terms of crop safety, beneficial arthropod safety, beet armyworm and cabbage looper control. Steward™ also appears to have advantages over pyrethroids, Larvin^®, Success^®/Tracer^® and Alert^®/Pirate^® in terms of Lygus suppression. DuPont anticipates Federal Registration of Steward™ to be granted in the second quarter of 2000. Steward™ 1.25SC is expected to be labeled in western cotton at rates of 0.065 to 0.11 lbai/ac (6.7 to 11.3 floz/ac) depending on lepidoptera species and pressure.
