What PRIMO® HG Turf Growth Regulator Offers

• Superior turf quality and colour
  Achieve finer, denser growth for a greener, more visually appealing lawn.

• Less mowing and fewer clippings
  PRIMO® HG slows excessive leaf growth throughout summer, reducing mowing frequency, minimising clipping disposal, and lowering the risk of scalping.

• Stronger, deeper root development
  By redirecting the plant’s energy below the surface, treated turf develops a more robust root system—improving water and nutrient uptake for overall lawn health.

• Better heat and stress tolerance
  PRIMO® HG helps pre-condition your lawn for hot, stressful summers, providing improved resilience, reduced wear, and lower watering requirements.

• Convenient growth control for up to 4 weeks
  A single application can slow leaf growth for up to a month—ideal for holidays or periods when you can’t mow regularly.

Application Guidance

Recommended application rates are designed to achieve approximately a 20–50% reduction in clipping yield over a 2–6 week period. Growth regulation typically begins 3–5 days after application.
Actual results may vary depending on environmental conditions and individual lawn management practices. For best performance, adjust application rates to suit your growing conditions, management approach, and the level of growth regulation required.
