Sepro Growth Regulators

Cutless MEC

(Flurprimidol)

2 x 2.5 Gal Case

Cutless* is a foliar applied and root absorbed plant growth regulator (PGR) for turf that reduces foliar shoot growth on a variety of turfgrass species. Cutless reduces shoot growth by interrupting the functions of gibberellic acid, and thus shortening the internodes, which reduces or slows the turfgrass's rate of growth, but does not impact its long-term development. Rather, using Cutless provides key benefits to treated turfgrass.

 

These benefits include:

  • Increased turf density

  • Improved turf color  

  • Reduced water use

  • Up to 50% reduction in mowing

  • Up to 50% fewer clippings

  • Suppresses Poa annua (annual bluegrass) populations in perennial turfgrasses

 

Additionally, Cutless is the leading turf PGR for Poa annua suppression. Cutless selectively suppresses the growth of annual bluegrass to a greater degree than desirable perennial turfgrasses, such as creeping bentgrass, shifting the competitive growth advantage away from Poa annua and towards creeping bentgrass. Therefore, over time, creeping bentgrass is able to grow laterally or “creep” into the suppressed Poa annua stand, resulting in successful conversion. This allows for a consistent and gradual conversion from Poa annua to creeping bentgrass with minimal disruption to the playability of the turfgrass. Programmed applications of Cutless have shown to reduce Poa annua populations by as much as 50 - 80% in the first year!

 

Impact of Cutless on turf growth

 

How Cutless works. Because it is antagonistic to both the formation and action of growth-promoting gibberellic acid in plants, Cutless causes a reduction in internode elongation. This makes turf more compact and lower growing.

 

Root effects and tillering. Cutless has no adverse effects on turfgrass root systems and helps encourage more tillers and stolons, with the net effect of increasing turf density.

 

Water use. Cutless reduces the leaf area of turfgrass plants. The smaller leaf area results in less water loss due to transpiration. In university tests, Cutless treatments resulted in water conservation from 11% to 29% compared to mowed untreated grass.

Color. At the peak of Cutless' growth effects, the grass turns a darker green color.

 

Cutless and turfgrass cultural practices

 

During the period of modified growth of Cutless treated turfgrass, changes in the following cultural practices can be expected.

 

Mowing

Because Cutless treated grass grows at a slower rate; it takes longer to reach normal mowing height. This reduces both mowing requirement and the quantity of grass clippings. If normal practice returns clippings to the ground, there will be less clipping residue and unsightly clumps of freshly mowed grass will be reduced or eliminated. Reduced volume of clippings also may slow the buildup of thatch in turfgrass.

 

Irrigation

Cutless treated turfgrass transpires less, resulting in less water used than on similar untreated grass, so irrigation frequency can be reduced. Research has demonstrated that Cutless treated turf can use up to 29% less water compared to untreated turf.

 

Weed suppression

Research has shown that Cutless will inhibit the growth of a number of troublesome broadleaf weeds, including prostate and spotted spurge, oxalis, clover, veronica, henbit and ground ivy. Additionally, Cutless will inhibit growth of some annual grasses—including Poa annua, crabgrass, goosegrass, foxtail and annual sedges.

Edgeless is used to slow the growth of most warm and cool-season turfgrasses.

Legacy

(Flurprimidol & Trinexapac Ethyl)

2 x 2.5 Gal Case

Legacy* Plant Growth Regulator (PGR) integrates patented† synergistic plant growth regulator technology to reduce stem elongation and leaf blade length in perennial warm- and cool-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 PGR spray intervals, discouragement of Poa annua (annual bluegrass), and more uniform growth regulation in mixed turfgrass stands.

 

Legacy’s patented site of action PGR synergy results in growth suppression, improved turfgrass color and quality, extended spray intervals, and suppression of Poa annua. Plant physiological advantages to applications of Legacy include:

 

  • Multiple plant sites of uptake: Legacy is absorbed by plants via roots, stems, and leaves; and

  • Multi-site activity within gibberellic acid (GA) biosynthesis pathway: Legacy inhibits GA production at both early and late stages in the pathway.

 

PGR absorption via the roots and foliage allows for more efficient uptake by the plant ensuring an optimal amount of active ingredient is available for GA inhibition. Additionally, blocking GA biosynthesis early and late in the biological pathway regulates GA more efficiently than at a single site within this cycle.

 

Benefits of Legacy applications to Turfgrass:

 

  • Shoot growth suppression of warm- and cool-season turfgrasses resulting in decreased mowing frequency and turfgrass clippings.

  • Increased turfgrass density, wear-resistance, and improved color on warm- and cool-season turfgrass species resulting in improved turf quality.

  • Suppression of Poa annua in cool-season turfgrasses.

  • Improved water use efficiency of warm- and cool-season turfgrass resulting in pre-drought stress conditioning. In university research, TGRs including the active ingredients in Legacy resulted in water conservation from 11% to 29% compared to mowed untreated grass.

  • Saves labor and fuel associated with mowing

  • Multiple plant sites of uptake provides synergy

 

Legacy is the only turf PGR on the market that is absorbed by the plant both via the shoots, crowns, and roots. Legacy provides both foliar, crown, 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.

 

Dual sites of action provides synergy

 

Legacy is the only turf PGR 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.
