Product Benefits
  • Season-long control of key turf-damaging grub species
  • Season-long control of caterpillars including black cutworms
  • Excellent annual bluegrass weevil control
  • Flexibility to allow rainfall to move the product into the soil or irrigate after application
Mode of Action

Chlorantraniliprole, the active ingredient in Acelepryn is a synthetic compound that affects the ryanodine receptors in the insect muscle fibre. Acelepryn binds to the ryanodine receptor and causes it to remain open, resulting in a depletion of calcium ions that disrupts muscle contraction.

Mode of Action: Ryanodine receptor modulator

Class of Chemistry

Acelepryn is the first turf product featuring an active ingredient from the anthranilic diamide class of chemistry. This class was inspired by research into the insecticidal properties of ryanodine – a natural substance found in the bark of trees and shrubs of the genus Ryania.

IRAC Group: 28

Application Information

Use Rates:

Apply ACELEPRYN Insecticide from (1.45 to 11.25 mL/100m²) based on target pest.

Bluegrass billbug, Chinch bug suppression, European crane fly larvae: 5.8-11.25 mL/100m2

Black turfgrass ataenium larvae, European chafer larvae, Japanese beetle larvae, June bettle larvae: 5.6 to 8.8 mL/100m2

Fall armyworm, Black cutworm, sod webworm: 1.45 to 2.9 mL/100m2

Annual bluegrass weevil: 8.8 to 11.25 mL/100m2

Water Volume:

Apply ACELEPRYN Insecticide in a minimum finished spray volume of (2 to 16 L/100m²) by ground.

Application Information:

European chafer larvae and Japanese beetle larvae: ACELEPRYN Insecticide may be applied from early April to late August for preventative and early curative control of European chafer larvae and Japanese beetle larvae infesting turfgrass. The need for an application may be based on historical monitoring of the site, previous records or experiences, current season adult trapping or other methods. The higher application rates listed above for European chafer larvae and Japanese beetle larvae control may be required for early season (April and May) applications where a long residual is required or in late August when less sensitive mid-instar grubs are present at the time of application

Black cutworms: ACELEPRYN Insecticide will provide curative cutworm control in turfgrass. To ensure optimum control, delay watering (irrigation) or mowing for 24 hours after application. If the area being treated is maintained at a mowing height of greater than one inch, then the higher rate listed below may be required during periods of high pest pressure.

Annual bluegrass weevil: ACELEPRYN Insecticide should be applied when overwintered adult annual bluegrass weevils are observed in late April or early May to prevent damage from larvae in late-May and June. An application of ACELEPRYN Insecticide at this time will also provide European chafer larvae and Japanese beetle larvae control. The higher rates listed above may be required for applications made after mid-May.

Mixing Order:

Spray equipment must be clean and free of previous pesticide deposits before applying ACELEPRYN Insecticide. Fill spray tank to ¼ to ½ full of water. Add ACELEPRYN Insecticide directly to spray tank.

Spray mix should not be stored overnight in spray tank.

Use Restrictions:

  • For any pests listed above, use the high rate under heavy pest pressure
  • Do not exceed a total of 1125 mL of ACELEPRYN Insecticide per hectare per season
  • Applications should not be made when the soil is saturated with water because adequate distribution of the active ingredient vertically in the soil profile cannot be achieved under this condition. Optimal results will be achieved if the product is irrigated into the turf immediately after application.
