 PGR - Plant Growth Regulator

Achieve professional-quality turf at home with Australia’s first turf growth regulator for home lawns!

Primo HG Turf Growth Regulator is the first product of its kind registered for use on home lawns in Australia, bringing professional turf management technology straight to your backyard. Primo HG helps homeowners achieve greener, denser, and more resilient lawns — while dramatically reducing mowing frequency and maintenance time.

Formulated to reduce vertical leaf growth and encourage stronger root development, Primo HG optimises turf density, colour, and stress tolerance. The result is a lawn that stays neat, healthy, and vibrant for weeks — even through Australia’s toughest summer conditions.

Key Features & Benefits of Primo HG Turf Growth Regulator

• First turf growth regulator approved for home use in Australia – Professional results, now available for home lawns.
• Greener, denser, and healthier turf – Promotes finer leaf texture and enhanced turf quality and colour with finer, denser growth
• Reduces mowing and clippings – Slows leaf growth for up to 4 weeks, meaning less mowing and cleaner lawn surfaces. It also means reduced clipping removal and less potential for scalping
• Pre-conditions turf for stress – Helps lawns withstand heat, drought, and wear during summer. Better heat stress tolerance, less wear and tear, and reduced watering needs
• Enhances root growth – Redirects plant energy below ground, promoting stronger, deeper, more efficient root systems. This improves the ability of your turf to utilise available water and nutrients
• Convenient and easy to use – Available in a 500 mL twin-chamber pack for precise application.

How Primo HG Turf Growth Regulator Works

Primo HG is absorbed through the turf leaf, where it acts to reduce elongation of stems, stolons, and leaves. This regulation of above-ground growth results in shorter, more compact turf without affecting root development.
By limiting excessive top growth, more energy is directed to the roots — improving nutrient uptake, water efficiency, and overall plant health.

Because Primo HG has no root absorption, correct foliar coverage during application is essential for best results. Growth regulation strength can be adjusted depending on turf type, season, and lawn conditions.

Primo HG Is Safe For The Following Turf Species

Warm-season grasses:
Bahia Grass, Buffalo Grass, Carpet Grass, Common Couch, Couch hybrids and varieties, Kikuyu.
