Primo Maxx® 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.  

Primo MAXX Plant Growth Regulator for turf growth management reduces the frequency of mowing and the amount of grass clippings by reducing the vertical growth of warm- and cool-season turfgrasses. Other benefits, such as increased turf density, increased color, and increased turf quality, are frequently observed after Primo MAXX Plant Growth Regulator applications.

Primo MAXX Plant Growth Regulator can be applied to well-maintained, quality turfgrass areas, such as residential and commercial lawns, golf courses, sod farms, sports fields, cemeteries, and similar areas. Primo MAXX Plant Growth Regulator is useful in the management of difficult-to-mow areas and can be used to minimize the need for edging turfgrass along sidewalks, curbs, parking lots, driveways, flower beds, fences and around posts, storage sheds, and trees.
