One application provides season-long control of grubs, billbugs and turf caterpillars

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

Acelepryn® insecticide has become the standard for grub control due to its consistent performance. A single application, applied early, delivers season-long control of grubs, billbugs and turf caterpillars such as armyworms, cutworms and sod webworms. The broad-spectrum control of Acelepryn is also effective against European Crane Fly and can suppress chinch bug populations. As an insecticide available for turf in group 28 (anthanilic diamides), the unique class of chemistry and powerful mode of action makes Acelepryn a great resistance management tool.


Acelepryn offers the most effective control when applied in April or May, but also delivers excellent control of grubs when applied in June (see table). The wide application window of Acelepryn gives turf professionals the flexibility to make grub applications at a time that is convenient for their operation. Due to 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.

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

There are several methods to make applications, including:

  • A foliar application to control leaf-feeding caterpillars and Japanese beetle adults
  • A soil drench to prevent lace bugs, aphids and birch leafminers
  • A bark spray to eliminate clearwing borers
  • Broadcast spray applications to landscape beds for grub control

For your convenience, Acelepryn is available in:

  • a half-gallon suspension concentrate (volume discount for 10 or more gallons)
  • a 25-pound granular and on fertilizer formulations
  • a convenient 4 fl. oz. Acelepryn SC package size is now also available to help with applications on smaller lawns.

Season-long control makes the difference
  • Our treatment program is extremely effective at controlling lawn insects and has little impact on beneficial insects customers do want in their yards, such as honey bees and earthworms.
  • There is no adverse effect on bumble bee colonies, even when the worker bees are exposed to flowering clover that is directly sprayed with Acelepryn*.
  • Acelepryn provides a superior level of grub control in customers’ yards, even when used at the lowest application rate in the industry.
  • Acelepryn can be used to treat with low use rates, which means less product is needed for turf insect control.

Acelepryn qualifies under one or more of the above criteria.
