Stadium quality turf with PGR’s

We know many of you are always looking for ways to take your lawns to the next level. One way to do this is by using what the turf professionals use, Plant Growth Regulators. Used on golf courses and sports grounds across the world, Plant Growth Regulators commonly known as PGR’s, are now available in an economical size to use in your own back garden.

In this article we focus in on the benefits of plant growth regulators, Primo Maxx by Syngenta specifically, that can help your lawn perform like stadium quality turf.

What is a Plant Growth Regulator or PGR?

A PGR is an innovative solution that influences a plant’s growth and development.

Recent types of PGRs, such as Syngenta’s turf growth regulator Primo Maxx are formulated as a micro emulsion concentrate that quickly enters the leaves and shoots before systemically moving throughout the entire plant.

Better looking lawns, faster:

  • Reduces grass growth: reduced mowing.
  • Less bare patches: improved aesthetic.
  • Greener grass.
  • The best-looking edges with less work.

Once absorbed, the active ingredient works to temporarily block the plant’s ability to produce a growth hormone called Gibberellic Acid. This suppresses the plant’s vertical growth while allowing normal processes like photosynthesis and respiration to continue.

Energy is diverted into the plant’s lateral growth, resulting in smaller and finer leaves, increased tillering, and a larger, deeper root mass. The turf becomes denser with a more vibrant colour.
