Plant growth regulators

Primo Maxx II

Primo Maxx® II can be used to help reduce turf management workload and improve turf quality by limiting cell elongation and vertical growth of turf grasses.

Primo Maxx® II contains the active substance, trinexapac-ethyl which blocks the production of gibberellic acid within the leaf leading to a more compact growth form.

Trinexapac-ethyl is activated by metabolic processes in the plant and is therefore most effective when soil temperatures are consistently >10°C. Activation within the plant occurs around 3-5 days after application and lasts for up to six weeks.

Whilst Primo Maxx® II is actively regulating plant growth, turf managers can expect a reduction in clipping yields and an improvement in playing surface quality. Use of Primo Maxx® II is also associated with greater rooting, and drought and shade tolerance.

Key benefits:

  • Reduces clipping yields

  • Creates a more compact grass growth form

  • Increases rooting, and drought and shade tolerance

  • Improves playing surface quality
