White grubs attack golf courses regularly from one year to the next. Once damage is suspected or scouting indicates a need for treatment, it becomes more difficult to control them, so an early, preventive treatment is ideal. Golf course superintendents can depend on Acelepryn^® insecticide for exceptional, season-long control with a single application. Acelepryn is available as a liquid or granular formulation. 98% of superintendents confirmed that compared to the insecticide they used before, Acelepryn exceeded expectations (n= 543).

Here are some of the key benefits of applying Acelepryn on your course to fight against unwanted grubs and other insects:

• Wide spectrum of control:
  • Acelepryn provides season-long control of every key turf-damaging white grub species and caterpillars including black cutworms, sod webworms and fall armyworms.
  • 93% of superintendents agree that the spectrum and length of control of Acelepryn saves them from making additional applications throughout the season. (n= 527 Acelepryn users).
  • Acelepryn makes an excellent rotation partner with other insecticides.

53% of superintendents make their grub/cutworm application late April/Early May. 18% apply in early April while 14% apply in late May.

• Early applications provide best results
  • Apply Acelepryn in April or May for best results.
  • The wide application window gives superintendents the flexibility to apply when the timing is right for their course operations and can be timed with a pre-emergent herbicide, especially for high-maintenance rough or highly visible areas. 97% agreed that the wide application window of Acelepryn enables them to apply it when it works best for my course (n= 529).
  • One properly timed application of Acelepryn is all that is needed for season-long turf protection.

• Favorable environmental profile
  • Acelepryn binds to soil particles and has low water solubility, which means its movement in the soil toward ground or surface water is limited.
  • Acelepryn is a non-neonicotinoid chemistry and has limited impact on beneficial insects and non-targeted insects, including bees.

• Protection beyond grubs
  • Besides delivering outstanding grub control, Acelepryn has proven performance controlling regional pests like billbugs, European crane fly and caterpillar species such as fall armyworm, black cutworm and sod webworm.

A properly-timed application of Acelepryn is also highly effective against the larvae of the annual bluegrass weevil (ABW), a destructive pest in the northeastern U.S.

Not only does Acelepryn offer best-in-class protection across this broad spectrum of turf pests, it is also an important tool for resistance management as it offers an alternate mode of action to pyrethroid chemistries. Visit WeevilTrak.com for the leading program approach for season-long control of ABW and up-to-the minute application timing in your area.

Guard your landscape ornamentals with Acelepryn
Acelepryn was granted a 2(ee) supplemental recommendation in many states, including California, expanding its use to control leaf-feeding Japanese beetle adults on ornamental plants in exterior landscapes and interior plantscapes. It can be applied in three ways:

• Directly on leaves to control leaf-feeding caterpillars, Japanese beetle adults and lace bugs
• Injected into the soil to combat birch leafminers, lace bugs and aphids
• To the bark to ward off pests such as clearwing borers
