Acelepryn Xtra insecticide

Acelepryn Xtra insecticide is the latest member of the Acelepryn family. It’s powered by two active ingredients and modes of action to deliver long-lasting, broad-spectrum insect control, including season-long control of grubs, billbugs and caterpillars, plus enhanced chinch bug control.

Season-long control

• Acelepryn Xtra provides season-long control of every key turf-damaging white grub species and caterpillars including black cutworms, sod webworms and fall armyworms
• It controls billbugs and also offers control of chinch bugs rather than suppression
• Additionally, it provides control of ants and can be used through second instar for grub control, providing the widest window of application for these damaging pests

A wider spectrum of insect control

Acelepryn Xtra is a combination of Acelepryn and Meridian^® insecticides, so it’s powered by two active ingredients and modes of action to deliver long-lasting, broad-spectrum insect control. Combining IRAC group 28 and IRAC group 4A also makes Acelepryn Xtra a great resistance management tool as it offers an alternate mode of action to pyrethroid chemistries.


Guards landscape ornamentals

• Acelepryn Xtra is also labeled for use on landscape ornamental plants including control of leaf-feeding Japanese beetle adults on ornamental plants in exterior landscapes. It can be applied in two 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

Timing Acelepryn applications

Acelepryn offers most effective control when applied in April or May, but also delivers excellent control of grubs when applied in June (see table below).

The wide application window of Acelepryn gives you the flexibility to make grub applications when it’s convenient for your operation. Because of its low water-solubility, Acelepryn applications made later in the season (June) should be watered-in so it moves into the soil where it will be available to newly hatched grubs.

Making applications

Acelepryn is a versatile product that fits well within a lawn care program. It’s also labeled for use on landscape ornamentals. Acelepryn is registered by the Environmental Protection Agency under its Reduced Risk Program¹.

There are several methods to apply, including:

• Foliar applications to control leaf-feeding caterpillars and Japanese beetle adults
• Soil drench applications to prevent lace bugs, aphids and birch leafminers
• Bark sprays to eliminate clearwing borers
• Broadcast spray applications to landscape beds for grub control
