  6. BCW ControlWith E2Y45 Percent Control E2Y45 0.53 lb E2Y45 0.11 lb Talstar 0.05 lb *cool weather

  7. 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

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

  10. 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 Provaunt vs. Talstar

  11. 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
