Turf Growth Regulators

Professional Turf Growth Regulators for Controlled Growth and Improved Turf Quality

Turf growth regulators, commonly called PGRs, help professional turf managers control vertical growth, reduce mowing frequency, improve turf density, suppress seedheads, and maintain a more uniform playing or appearance surface. These products are widely used on golf courses, sports fields, commercial landscapes, parks, sod farms, and other professionally managed turf areas.

Intermountain Turf Supply offers professional turf growth regulators for cool-season and warm-season turfgrass. Depending on the active ingredient and label, PGRs may be used for routine growth management, Poa annua suppression, seedhead suppression, clipping reduction, improved turf color, enhanced density, or reduced scalping stress.

Benefits of Turf Growth Regulators

Choosing the Right Turf Growth Regulator

Turf growth regulators differ in how they enter the plant, where they act, and the turf responses they produce. Some products are absorbed through foliage, while others are taken up through roots. Product selection should be based on the turf species, management objective, application site, active ingredient, expected growth response, and environmental conditions.

Some PGRs are used primarily for routine clipping reduction and turf quality, while others are selected for seedhead suppression, Poa annua suppression, or targeted growth regulation. Always review the product label to confirm labeled turf species, application timing, rate, retreatment interval, watering instructions, and use-site restrictions.

Application Timing and Turf Response

For best results, apply turf growth regulators to healthy, actively growing turf that is not under severe drought, heat, disease, nutrient, or traffic stress. Turf response can vary with temperature, growth rate, application interval, nitrogen fertility, irrigation, and mowing practices.

Sequential applications are commonly used to maintain consistent regulation throughout the growing season. Avoid extending intervals so far that turf experiences excessive rebound growth. Always follow label directions regarding repeat applications, maximum use rates, tank mixtures, and required irrigation.

Professional PGR Programs

A well-managed PGR program can improve turf consistency while reducing mowing and clipping production. Golf course superintendents, sports turf managers, lawn care professionals, and grounds managers should select products based on the desired level of regulation and the specific turfgrass being treated.
