Acelepryn Insecticide | GreenCast | Syngenta

Product Overview

Much More Than Unsurpassed Grub Performance

Powered by the active ingredient chlorantraniliprole, Acelepryn® insecticide provides excellent, season-long grub control with a single (8–16 fl oz/A) application in April or May. But Acelepryn is more than just outstanding grub control. That same application for grubs will control many key surface feeding pests including several species of caterpillars as well as annual bluegrass weevil (ABW). For ABW, apply 12–20 fl oz/A, which will provide an even broader spectrum of effective control.
Unlike other grub control materials, Acelepryn provides the best results when applied early. The wide application window allows superintendents the flexibility to apply when the timing is right for them.
Acelepryn is a critical component of an effective, long-term strategy to control ABW. Not only does it offer best-in-class control of ABW, it is also an important component for resistance management. Acelepryn controls ABW small larvae that feed inside grass stems, while Provaunt® WDG insecticide controls larger or older larvae feeding on the crown of grass plants.

Favorable Environmental Profile for Pollinator Protection

Acelepryn is registered by the Environmental Protection Agency under its Reduced Risk Program*. Additionally, Acelepryn does not have a signal word on its label because of the results of required acute toxicity studies conducted on the formulation. It is a good fit for controlling insects on lawns, sport fields and golf courses where preservation of beneficial and non-target organisms is a concern.

Bee foraging activity five and six days after treatment

Dr. Daniel Potter from the University of Kentucky has conducted studies to examine the impact of Acelepryn on beneficial and non-target organisms including earthworms and honeybees.

His results found that Acelepryn did not adversely affect bumble bee colony foraging even when the worker bees were exposed to flowering clover that had been directly sprayed.1

Bee mortality five days after treatment

Colonies foraging on turf treated with clothianidin had higher worker and brood mortality, reduced honey pot production, delayed weight gain and impaired queen production compared to controls.1

Chlorantraniliprole, part of the newer anthranilic diamide class of chemistry, can control many of the same pests that are targeted with neonicotinoids and pyrethroids including white grubs, caterpillars, and billbugs. However, it does not have any documented effects on pollinating insects and may be a good fit for industry initiatives to reduce the impacts of turf and landscape management on pollinators.”

Control unwanted grubs and more

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.  Read more »


Get industry-leading control of unwanted grubs

Acelepryn® insecticide has become the standard for grub control due to its excellent 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 novel mode of action makes Acelepryn a great resistance management tool.  Read more »

These codes, represented as Fungicide Resistance Action Committee (FRAC) codes, Insecticide Resistance Action Committee (IRAC) codes and Herbicide Resistance Action Committee (HRAC) codes, are typically listed on product labels.  Read more »
