The recent introduction of Acelepryn^® Xtra insecticide enhances grub control and more. It’s powered by two active ingredients found in Acelepryn and Meridian^® insecticides (IRAC group 28 and IRAC group 4A) to deliver long-lasting, broad-spectrum insect control. Just one early application provides season-long control of grubs, billbugs and caterpillars. Plus, it also features ant control and enhanced chinch bug control.

Acelepryn Xtra delivers:

1. Wider spectrum of insect control:
   • Six to eight weeks of ant control with significantly reduced ant mound formation
   • Significantly enhances chinch bug control over Acelepryn, which is only labeled for suppression
   • Suppression of mole crickets

     	Efficacy against nuisance turfgrass ants

2. Wider application window
   • Like Acelepryn, applications can be made as early as April
   • Acelepryn Xtra provides early curative control of grubs through the second instar
     • This allows for applications to be made well into July, even August in some cases for greater flexibility. Note, watering in becomes even more critical with later applications to maintain leading efficacy.
3. Outstanding season-long control
   • The 20 fl. oz./A rate of Acelepryn Xtra offers the equivalent of 10 fl. oz./A of chlorantraniliprole and the full rate of thiamethoxam 
     • Leads to outstanding control of all major turf-damaging white grub species and caterpillars, such as black cutworms, sod webworms and fall armyworms 
   • May-June applications of Acelepryn Xtra at the 20 oz. rate will provide equal to or greater control of grubs while also providing season-long control of billbugs and six weeks of hairy chinch bug control (up to 12 weeks of Southern chinch bugs)
