Primo Maxx® plant growth regulator promotes denser, healthier turf that is better able to withstand a variety of stresses including heat, drought, diseases and traffic. It slows the production of gibberellic acid, a plant hormone that promotes cell elongation. Vertical shoot growth is slowed, while lateral and below-ground growth of rhizomes, stolons, tillers and roots is stimulated.
