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

*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
