Why Primo HG

Mow less, and get a thicker lawn for it

A turf growth regulator that slows leaf and stem growth, so your lawn puts that energy into density and colour instead of height.

  • 120 g/L trinexapac-ethyl, the active turf pros use
  • Cuts clippings by 20 to 50% over 2 to 6 weeks, so you mow far less
  • Drives a greener, denser, more resilient lawn
  • Pre-conditions turf for stress and lifts surface quality
How to use

Regulate growth in three steps

1
Mix

Shake well, half-fill your sprayer, add the label rate of Primo HG, then top up with water and shake to mix.

2
Spray

Spray evenly across the whole lawn. Avoid mowing for 6 hours either side of application.

3
Repeat

Reapply every 2 to 6 weeks through the growing season, adjusting the rate to your conditions.

Questions

Good to know

What does a growth regulator actually do?+
It slows down leaf and stem elongation, so your lawn grows up more slowly and puts its energy into density and colour. The result is fewer clippings, less mowing and a tighter, stronger lawn.
How much less will I mow?+
Application rates are designed to cut clippings by 20 to 50% over a 2 to 6 week period. Conditions and how you manage the lawn affect the result, so you can adjust the rate to suit.
How fast does it work?+
Growth regulation begins within 3 to 5 days of spraying.
Can I use it on any lawn?+
Yes, it can be used on all lawns. Measure your lawn first so you mix accurately and get even coverage.
Any tips for applying it?+
Avoid mowing for 6 hours before or after application, only mix what you will use on the day, and rinse your sprayer thoroughly with clean water afterwards.

Mow less, grow a better lawn

Slow the vertical growth and let your lawn thicken up instead. Professional turf quality, less time behind the mower.
