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 lb Dylox lb Dursban -1 lb no ABW resistance as with pyrethroids controls cutworms very low environmental and applicator risk

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

BCW Control With Provaunt Percent Control b a aa a aa a c bc ab a *p=0.05, DMRT

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

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
