"For courses that refuse to compromise, Spectrum delivers consistent playability from the first round to the last."

Bred by the Best in Bentgrass Research

Dr. Stacy Bonos of Rutgers University has spent decades developing some of the most disease-resistant and performance-driven turfgrass cultivars in the industry. Spectrum (officially designated LNS 19) is among her most refined achievements — the product of rigorous field trials and genetic selection aimed squarely at the demands of modern putting surfaces.

GreenSource is proud to bring this cultivar to superintendents and course managers who understand that the right seed is a long-term investment in playability and cost control.

Built-in Disease Resistance Saves Real Money

Dollar Spot, Brown Patch, and Anthracnose are among the most costly and disruptive diseases a golf course can face. Together, they can devastate putting surface quality almost overnight — and fighting them with fungicides is expensive. Spectrum's superior genetic resistance to all three reduces both the frequency and cost of chemical applications, allowing maintenance teams to redirect budget toward other priorities.

Over the course of a season — and especially across several seasons — those savings compound significantly.

Spectrum Benefits at a Glance

Disease Resistance  Superior protection against Dollar Spot, Brown Patch, and Anthracnose.

Lower Maintenance Costs  Reduced fungicide dependency translates to meaningful long-term savings on chemical and labor.

Fine Putting Surface  Excellent mowing qualities produce a smooth, consistent roll that golfers will notice from day one.

High Turf Density  Dense stand formation crowds out Poa Annua invasion — a persistent challenge on aging greens.

Traffic Tolerance  Handles both foot and cart traffic with improved resilience through high-play periods.

Interseeding Compatible  An excellent choice for renovating tired or underperforming greens without full reconstruction.

Keeping Poa Annua Where It Belongs

Poa Annua invasion is one of the most persistent headaches in putting green management. Once established, it disrupts surface uniformity and creates problematic seed heads during play. Spectrum's exceptionally high turf density provides a natural barrier — a thick, well-established stand simply leaves little room for unwanted grasses to gain a foothold.

Renovation Without Reconstruction

Not every green needs to be torn up and rebuilt. For courses looking to improve surface quality without the expense and downtime of a full renovation, Spectrum is purpose-built for interseeding into aging or underperforming greens. The cultivar establishes well in existing turf and gradually elevates the playing surface over time — a cost-effective path to premium conditions.
