Primo Maxx II

Primo Maxx II is a liquid formulation grass growth regulator that works by redirecting plant growth, specifically targeting the gibberellic acid site that is responsive for cell elongation in grass.

Primo Maxx II inhibits vertical growth and diverts plant growth downward into the root system to produce increased lateral stem movement. This results in a thicker, healthier sward that better equips turf to withstand temperature extremes, moisture loss, traffic and wear and even helps in the management of Poa annua.

All applications start mid-April. Max treatments - 5 full rate per year. Recommended for use on greens, golf tees, fairways, semi-rough and rough grass areas.
