Throughout the history of the turf management industry, professionals who develop innovations in equipment, products and methods have eagerly handed down their wisdom and experience to the next generation.

That's why SePRO Corporation is proud to establish its legacy in the form of the latest advancement in turf growth regulation.

Legacy. The Next Generation of Turf Growth Regulation Technology.

• Enhanced growth suppression
• Improved turfgrass color and quality
• Extended spray intervals
• Reduced “bronzing”
• Elimination of the “rebound” effect
• More uniform growth regulation on mixed turfgrass varieties
• Stops the encroachment of Poa annua

A New Legacy is Handed Down
Legacy Turf Growth Regulator (TGR) integrates patented synergistic turf growth regulator technology to reduce stem elongation and leaf blade length in perennial cool- and warm-season turfgrasses on golf courses resulting in a more compact and dense growth habit.  Legacy uniquely suppresses Gibberellic Acid (GA), the plant hormone responsible for cell elongation in most plants, which leads to its unsurpassed growth regulation.

Legacy's synergistic growth regulation, resulting from its dual sites of action and plant uptake, leads to enhanced growth suppression, improved turfgrass color and quality, extended TGR spray intervals, discouragement of Poa annua, and more uniform growth regulation in mixed turfgrass stands.

Dual Sites of Action Provides Synergy
Legacy is the only TGR that suppresses growth by inhibiting the production of Gibberellic Acid (GA) at two different sites within the biosynthetic pathway.  By inhibiting GA production both early and late in the GA pathway, Legacy provides unparalleled GA inhibition efficiencies within the turfgrass plant.

Turf Growth Regulation from Top to Bottom
In addition to GA inhibition at two different sites within the plant, Legacy enters the plant at multiple sites.  Legacy provides both foliar and root uptake, ensuring sufficient active ingredient is translocated throughout the plant for maximum growth regulation to occur.  The dual sites of uptake and action result in less potential for initial bronzing or discoloration.  Legacy's systemic action quickly distributes the active ingredients to the growing point of the plant leading to unsurpassed growth regulation.

Eliminate the “Rebound” Effect with Legacy
An application of a foliar-absorbed TGR acting at a single site late in the GA pathway can often lead to a flush of growth near the end of the treatment cycle.  This unwanted and proven phenomenon, known as the “rebound” effect, occurs when the plant has completely metabolized the active ingredient and suddenly resumes active growth.  Fortunately, Legacy's root-absorption component can eliminate this effect leading to a slower release of treated turfgrass, allowing you more time to make a subsequent application without scalping the turf or dealing with excessive clippings.

Improved Overall Turf Quality
Just as turf maintenance equipment, fertilizers and cultural practices have improved over the years to help improve golf course playing conditions, now Legacy improves TGR technology.  Legacy helps you to meet the high expectations you have for your golf course by providing superior turf density, darker green color with reduced initial bronzing or discoloration, less scalping, and improved overall turf quality.

Extended Control
Legacy has shown to provide enhanced growth control when compared to other plant growth regulators.  This allows superintendents to extend their spray TGR intervals resulting in fewer treatments annually, as well as labor and fuel savings. 

One indicator of the lack of residual control in TGRs on warm-season grasses is scalping.  When warm-season turfgrass is regulated, the crown of the plant remains below the cutter head of the mower, thereby avoiding scalping.  However, the crown of a rapidly growing plant oftentimes will reach well into the mowing zone resulting in scalped turf.  The photos below depict this phenomenon and demonstrate the excellent residual control provided by Legacy.

Note the lack of Scalping in this Tifsport Bermudagrass treated with two applications of Legacy at 14.7 oz. per A. Lack of scalping is an indicator of the extended growth regulation provided by Legacy.

Stop the Encroachment of Poa annua with Legacy
A growth regulation program using Legacy suppresses Poa annua in cool-season turfgrasses.  Research has demonstrated that programmed applications of Legacy are very effective at suppressing Poa annua populations in cool-season turfgrasses when compared to applications of trinexapac-ethyl alone, which are shown to encourage Poa annua populations.

For Poa annua conversion, users should consider programmed applications of Cutless* 50W alone.  Cutless 50W has been proven to be the premier product for superintendents wanting to shift the competitive advantage from Poa annua to the desired turfgrass species, and hence reduce their Poa annua populations.
