Steward(TM) insecticide, indoxacarb, is a new and novel insecticide from DuPont Agricultural Products. Indoxacarb is from the oxadiazine class of chemistry. Steward(TM) has been evaluated in western cotton for 7 years (1993-1999). In Arizona and California studies, Steward(TM) has consistently provided effective knockdown and residual control of beet armyworm and cabbage looper larvae in Bt and non-Bt varieties. Steward(TM) has also exhibited short term (2-6 days) suppression of Lygus bugs, particularly nymphs. Steward(TM) 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(TM) also appears to have advantages over pyrethroids, Larvin®, Success®/Tracer® and Alert®/Pirate® in terms of Lygus suppression. DuPont anticipates Federal Registration of Steward(TM) to be granted in the second quarter of 2000. Steward(TM) 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.
