13. The E2Y45 Advantage controls ABW and white grubs – 1 application at 0.25 lb in early May (adult emergence) saves up to 5 applications for ABW – Talstar Dursban Deltagard Dylox Tempo Scimitar Merit - 0.3 lb Dylox - 8.2 lb Dursban -1 lb no ABW resistance as with pyrethroids controls cutworms very low environmental and applicator risk

14. new mode of action – helps in resistance management controls cutworms too low risk

16. Provaunt vs. Talstar Talstar GC (bifenthrin) LD50 = 70 mg/kg* restricted use toxic to fish NY- 100’ buffer (turf) L.I. – banned (GC turf) pyrethroid resistance likely (ABW) hard on beneficials * tech., male rat Provaunt (indoxacarb) LD50 = 1732 mg/kg* reduced risk greater aquatic safety buffers not likely required not likely to be banned novel m.o.a. soft on beneficials-good for IPM

17. Summary more research needed on timing, rates, formulations, residual, and pest activity for E2Y45 and Provaunt to further define role excellent new tools for turf insect management
