Description
Acelepryn GR Turf Insecticide, manufactured by Syngenta Australia, controls season-long grub and caterpillar populations in Australian turf with a single granular application. Formulated with 2g/kg chlorantraniliprole, this Group 28 insecticide targets African Black Beetle, Argentinian Scarab, Billbugs, and caterpillars, including Cutworm, Sod Webworm, and Lawn Armyworm, across golf courses, sports grounds, and domestic lawns.
Acelepryn GR delivers up to six months’ protection at higher application rates without requiring poison scheduling. This no-spray formulation reduces PPE requirements for workers and offers minimal disruption to the community. The granule formulation provides flexible application in tight or difficult-to-access turf areas such as schools, passive parks, and around obstacles.
How does Acelepryn GR control turf insects?
Chlorantraniliprole disrupts calcium channels in insect muscle cells, causing paralysis and death. The active ingredient binds to receptors specific to insects, offering targeted control with minimal impact on non-target organisms.
Higher application rates (150kg/ha) deliver season-long control of up to six months. The granule formulation spreads easily through professional turf fertiliser spreaders and requires irrigation with approximately 6mm of water immediately after application for optimal activation.
When should I apply Acelepryn GR?
- African Black Beetle and Argentinian Scarab: Apply from spring onwards for preventative control. Use higher rates (150kg/ha) for early season application (mid-September) where you need long residual protection, or in later season applications (mid-December onwards) when less sensitive mid-instar grubs populate the turf.
- Argentine Stem Weevil and Billbugs: Apply when you first observe overwintered adults in early season (mid-September) to prevent damage and population build-up.
- Caterpillars: Apply when you observe pests or damage. Delay irrigation and mowing for 24 hours after treatment for optimal curative control.
Can Acelepryn GR be used in schools and public spaces?
Yes. Acelepryn GR requires no poison scheduling, re-entry periods, or PPE requirements. This makes it ideal for schools, parks, and other high-traffic turf areas. The no-spray granular option offers ease of use and minimal disruption to community spaces.
What spreader settings should I use?
Application rates range from 75kg/ha to 150kg/ha. The product is SGN 150. Spreader settings vary by manufacturer and model. Calibrate equipment to achieve the desired application rate using wheel-to-wheel coverage. Settings are approximate and provide a starting point only.
Is Acelepryn GR safe for turf?
Yes. Field trials demonstrate high turf safety across warm-season and cool-season grasses. The product delivers low environmental impact and carries registered safety claims for use around dung beetle and earthworm populations when you follow label directions.
How quickly does Acelepryn GR start working?
The granular formulation activates through irrigation within hours of application. Protection builds as the active ingredient moves through the soil profile and feeding larvae take it up. Visible pest reduction typically occurs within days, with full season-long protection developing over the first weeks following treatment.
