Primo HG 500ml

Slow Growth, Build Roots, Stress-Proof Your Turf

Primo HG is the industry-standard plant growth regulator trusted by turf professionals across Australia. By inhibiting gibberellic acid — the hormone responsible for vertical shoot growth — Primo HG redirects the plant's energy downward into roots, stolons, rhizomes and tillers. The result is a denser, stronger, more stress-tolerant turf that requires less mowing and performs better under heat, wear and disease pressure.

A must-have tool for pre-conditioning turf ahead of summer stress, or for maintaining premium presentation on sports fields and fine turf areas.
