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 preconditions turf for stress and optimises surface quality and colour. Achieve professional turf quality at home.

Recommended application 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.


TIP 1: Mix one cap of household dishwashing liquid or Manta Ray Surfactant (follow label rates) into your prepared, diluted Primo HG (follow label rates) to help effectively penetrate the leaf of the turf. This addition enhances the uptake of liquid products.
TIP 2: You should apply lawn products such as Primo HG when temperatures are lower than 25 degrees Celsius; ideally in the early morning or late afternoon. Avoid applying products in the middle of the day when the sun is at its hottest. When products are applied when the sun is at its hottest, you are more likely to experience some burning to the leaf.
