Primo Maxx II Growth Regulator

MAPP no. 17509

Active Ingredients: 116.4 g/l trinexapac-ethyl

The ultimate growth regulator for the improvement of turf performance.

Trinexapac-ethyl is the active ingredient in Primo Maxx II that works by redirecting plant growth. It specifically targets the gibberellic acid site responsible for cell elongation in grass.

Changes in a co-formulant ingredient mean that products with the previous MAPP no. 14780 was available for sale until the 30th April 2017 with a use-up period expiring on the 30th April 2018. The new MAPP no. 17509 has replaced this product.

Not only does Primo Maxx II inhibit vertical growth, but actually diverts plant growth downward into the root system to produce increased food reserves and lateral stem development. This in turn produces a thicker, healthier sward that better equips your turf to withstand temperature extremes, moisture loss, traffic and wear and tear, and even helps in the management of Poa annua.

Primo Maxx II can be used on all well maintained quality turf grass areas such as golf course fairways, golf tees, greens and surrounds. It can also be used to help manage areas which are difficult to mow such as sloping banks or turf edges by flower beds and pavements.

• Easy to use liquid formulation.
• Reduces grass top growth.
• Flexible application rates for all turf surfaces.
• Improves turf colour and appearance.
• Cuts down mowing frequency - one application can reduce grass clippings by up to 50%.
• Cuts down wear and tear on machinery.
