Primo HG Turf Growth Regulator 500mL - Syngenta
Primo HG Turf Growth Regulator by Syngenta – 500mL
Primo HG is the only turf growth regulator registered for home use in Australia. Developed by Syngenta, this professional-grade lawn care product promotes greener, denser, and more resilient turf while significantly reducing mowing frequency.
Key Benefits
- Reduced Mowing: Achieve a 20–50% reduction in clipping yield over a 2–6 week period, meaning less time spent on lawn maintenance.
- Greener, Denser Lawn: Primo HG regulates leaf and stem elongation, encouraging lateral growth for a thicker, healthier turf canopy.
- Stress Pre-Conditioning: Pre-conditions turf against environmental stress, helping your lawn withstand heat, drought, and wear.
- Professional Turf Quality at Home: The same trusted growth regulator used by turf professionals on golf courses, sports fields, and commercial landscapes.
Active Constituent
120 g/L Trinexapac-ethyl — a proven plant growth regulator that slows vertical growth while enhancing turf colour and density.
How to Use

- Add half the required water to your sprayer, then add the required quantity of Primo HG.
