Get the most out of your grub control

By Matt Giese, M.S., technical services manager for Syngenta

Early treatment is the key to white grub control, so it’s important to make sure you have the products you need on hand to get started in the spring. 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.1

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

  1. Flexible financial solutions
    • GreenTrust® 365 members can defer payment until late June with SummerPay™ terms.
    • Members can use Acelepryn for grub control between April and mid-June and choose to pay any time before July.
    • With purchases 10 gallons or more, Syngenta offers a volume discount.

  2. 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 the spectrum and length of control of Acelepryn saves them from making additional applications throughout the season.1
    • Acelepryn makes an excellent rotation partner with other insecticides.

  3. Early applications provide best results
    • Apply Acelepryn in April or May for best results
      • In the above graph, 53% of superintendents make their grub/cutworm application late April/Early May. 18% apply in early April while 14% apply in late May
    • 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 roughs or highly visible areas. 97% agreed that the wide application window of Acelepryn enables them to apply it when it works best for their course.1
    • One properly-timed application of Acelepryn is all that is needed for season-long turf protection.

  4. 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.

  5. 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, but it is also an important tool for resistance management as it offers an alternate mode of action to pyrethroid chemistries.

  6. Guards landscape ornamentals
    Acelepryn was granted a 2(ee) supplemental recommendation in the state of 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
