Scheduling grub control treatments for a golf course can be demanding. Traditionally, the key to white grub control was to apply midsummer, and then it changed to early spring applications. With Acelepryn^® Xtra insecticide from Syngenta, superintendents can make their own flexible treatment schedule to achieve season-long control with just one application. 

If May works – great! Can’t get to it until August? No problem. Acelepryn Xtra has the widest application window and the longest residual control for white grubs in the industry. It also provides excellent turf caterpillar and billbug control, offering a broad spectrum for anything else that crawls along. Congrats! You’ve just earned an “Xtra” day off.  

A wider spectrum of insect control  

Acelepryn Xtra is a combination of Acelepryn and Meridian^® brand 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 since it offers an alternate mode of action to pyrethroid chemistries. 

With this combination product, superintendents can enjoy: 

• Season-long control of grubs, billbugs and caterpillars with one application 
  • Acelepryn Xtra provides turf managers with the ultimate flexibility in fall armyworm management. With its systemic activity and long soil residual, Acelepryn Xtra not only provides rapid knockdown of existing outbreaks, but also provides extended residual control to prevent subsequent generations
• Early curative control of grubs, leading to greater flexibility and fewer applications 
• Enhanced chinch bug control, including at least three months of southern chinch bug control 
• European crane fly and ant control with reduced ant mounding 

Using Acelepryn Xtra 

The maximum annual rate of Acelepryn Xtra is 20 fl. oz./A. At the high rate, Acelepryn Xtra delivers the equivalent of 10 fl. oz./A of Acelepryn and 17 oz./A of Meridian 25WG for powerful insect control on golf course turf.  

For best results to control ants, combine Acelepryn Xtra with Scimitar^® GC insecticide when ant mounds are first observed and colonies are still weak as they emerge from winter. Learn more about how to control turfgrass ants for up to eight weeks.
