Acelepryn | Acelepryn Xtra | Timing applications | Late-season applications

AceleprynĀ® insecticide is the standard for grub control with excellent performance. A single application, applied early, can deliver season-long control of grubs, billbugs and turf caterpillars such as armyworms, cutworms and sod webworms. 


Acelepryn Xtra: Enhance control and widen the application window

Acelepryn Xtra insecticide is 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. It also offers control of ants and early curative control of grubs through the second instar, leading to greater flexibility and fewer application.

Timing: Don’t get caught off guard this season

Early to mid-June is ideal for applying Acelepryn Xtra at the 20 fl. oz./A rate for season-long control of fall armyworm, white grubs and billbugs. This rate can also offer:
  • Turfgrass ant control
  • Late-instar grub control (through the second instar) 
  • Six weeks of chinch bug control
  • Mole cricket suppression
Acelepryn Xtra can also be applied at the following rates for these specific uses:
  • 16-20 fl. oz./A for additional grub control, along with turf caterpillar, ant, and billbug control
  • 10 fl. oz./A in mid to late July to prevent fall armyworm for at least two months

If early insecticide applications for white grubs don’t fit into your program, consider incorporating CaravanĀ® G insecticide/fungicide:

  • When you need to combat both insect and disease pressure at the same time, Caravan G offers the convenience of an insecticide and fungicide in one product. It contains the same active ingredients found in HeritageĀ® fungicide  and Meridian insecticide for complementary control. While timing and geographies vary, one application of Caravan G made in June or early July can yield season-long grub control and three weeks of preventive brown patch control.

No matter which application timing is most convenient for your business, Syngenta has a solution for your grub control needs. For more information, contact your local Syngenta territory manager.
