Reduce Mowing and Suppress Bluegrass Seedhead Production with the Right Turf Growth Regulators

Keep the playing quality of putting surfaces top-notch with some of the best turf growth regulators you can find right here at Reinders.

The organic compounds found with turf and plant growth regulators work in very low concentrations to dictate the growth rate of plants, whether aiming to increase it or decrease it.

Plant Growth Regulators

Five commonly recognized groups of plant hormones include auxins, gibberellins, cytokinins, abscisic acid, and ethylene. To better understand how these hormone groups work together to coordinate plant development, let's take a brief look at the active role each hormone plays during the process.

  • Auxins: Stimulate cell elongation. This hormone influences root initiation, vascular differentiation, and auxiliary bud, flower, and fruit dominance and development.
  • Cytokinins: Stimulate cell division while inducing shoot bud formation into the plant's tissue culture.
  • Gibberellins: Most commonly used for causing stem elongation and flowering. This hormone works best during early seed germination.
  • Abscisic Acid: ABA regulates seed germination that includes protein synthesis and water stress modulation. It also aids in somatic embryogenesis during plant germination and maturation.
  • Ethylene: Although vegetative growth does not require ethylene, this hormone can significantly impact root and shoot development.

Knowing what hormones comprise most lawn growth regulators allows us to uncover how they work to achieve things like reduced mowing frequency, improved turf management, and various seedhead suppression.

Improve Mowing Management

Plant Growth Regulators

A suitable plant growth regulator can reduce the elongation of turf leaf blades based on your needs— thus, reducing mowing frequency.  

Not only will you decrease the wear and tear on your mower, but you can also save on things like fuel and labor! Handling clippings has also never been easier, thanks to a lesser amount.

Using PGR correctly allows you to manage mowing in an efficient way, depending on a few different factors.

  • First and foremost, the timing of your plant growth regulator application plays a significant role. We recommend applying PGRs early on in the season for more significant reduction.
  • Next, know the turf species you're treating.
  • Lastly, consider the rate and frequency of your plant growth regulator applications.

After taking all of these factors into consideration, you'll be able to make a well-informed product choice to reduce mowing by 40 to 60 percent without sacrificing your turfgrass quality!

Suppress Seedhead Production

When it comes to turf growth management, you'll want to consider how seedheads like Poa annua, bluegrass, or white clover can play a role in the decline of your golf course's playability or appearance. These nuisance weeds can cause thinning, clumps, lateral growth and reduce the overall quality of putting and playing surfaces.

By using plant growth regulators as turf managers, you can ensure that the energy once used to form a seed will be diverted to the plant's overall health. Seedhead suppression allows you to maintain the highest quality of turf grasses for professional-level playability.
