The e2y45 advantage
The E2Y45 Advantage Management

  • 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

Provaunt vs talstar

Talstar GC (bifenthrin) Management

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


Summary
Summary Management

  • 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
