Primo HG Turf Growth Regulator 500ml

Primo Maxx is now available in a smaller size approved for domestic use in the home garden - Introducing Primo HG Turf Growth Regulator.

PRIMO® HG Turf Growth Regulator will promote greener, denser, more resilient lawns, reduced height of leaf growth, fewer clippings and therefore less time spent on maintenance. PRIMO® HG is the trusted growth regulator that pre-conditions turf for stress and optimises surface quality and colour. Achieve professional turf quality at home. 

Available in an easy-to-use 500 mL twin chamber pack approved for home garden use.

What PRIMO^® HG Turf Growth Regulator offers you: 

• Enhanced turf quality and colour with finer, denser growth 


• Reduction of excessive leaf growth throughout summer – meaning less mowing plus reduced clipping removal and less potential for scalping 


• Redirects the plants energy to the root system – treated turf grows a stronger, deeper and more robust root system, improving the ability of your turf to utilise available water and nutrients 


• Pre-conditions your lawn for hot, stressful summers – better heat stress tolerance, less wear and tear, and reduced watering needs 


• PRIMO® HG can slow turf leaf growth for up to 4 weeks – so if you are going on holiday, one application prior to leaving means that your lawn doesn’t get out of control while you’re away 

Recommended applications rates are designed to give approximately a 20 to 50% reduction in clipping yield over a 2 to 6 week period. Growth regulation begins 3 to 5 days after application. The amount of growth regulation achieved will vary between situations due to environmental conditions and lawn management practices. Therefore, application rates will need to be adjusted to match growing conditions, management practices and the amount of growth regulation required in each individual situation. 

ACTIVE CONSTITUENT: 120 g/L TRINEXAPAC-ETHYL
