Sugarcane growth, sucrose content, and yield response to the ripeners glyphosate and trinexapac-ethyl
… harvest. The chemical ripeners, glyphosate and trinexapac-ethyl were applied to the sugarcane cultivars HoCP 96-540, L 99-226, L 99-233, HoCP 00-950, and L 01-283 eight weeks prior to harvest. When glyphosate was applied at 210 g ae/ha, TRS for the cultivars was increased 10 to 28% compared with …

Physiology and Growth Responses of Cool Season Turfgrasses Treated With Trinexapac -Ethyl or Paclobutrazol
Plant growth regulators (PGRs) such as trinexapac-ethyl (TE) and paclobutrazol (PAC) are often routinely applied to highly managed turfgrasses to suppress clipping production, increase sward density, and enhance color. However, reports of variability in the seasonal responses of PGRs indicate …

Overseeded Bermudagrass Fairway Performance and Post Dormancy Transition as Influenced by Winter Overseeding Practices and Trinexapac-ethyl
… conducted to determine the potential influence trinexapac-ethyl (TE), a plant growth regulator used by many professional turfgrass managers to suppress foliar growth, has on encouraging overseeded species to transition to bermudagrass. These studies demonstrated that higher overseeding rates …

Total nonstructural carbohydrate (TNC) flux of creeping bentgrass receiving sequential applications of growth retardants
Turfgrass growth retardants, trinexapac-ethyl, flurprimidol and paclobutrazol were treated in an initial greenhouse study but only trinexapac-ethyl was included in subsequent field and greenhouse experiments. Applications of trinexapac-ethyl (0.28 kg ha$\sp{-1}),$ flurprimidol (0.56 kg …

Prohexadione Calcium for Turfgrass Management and Poa annua Control and Molecular Assessment of the Acetolactate Synthase Gene in Poa annua
… professional turf. The plant growth regulators trinexapac-ethyl and paclobutrazol are commonly used in VA for these two costly and challenging jobs. Prohexadione calcium (PC) is an experimental chemical that inhibits the same enzyme (3ß-hydroxyalase) as trinexapac-ethyl and may selectively …

The Use of Plant Growth Regulators to Improve the Traffic Tolerance and Repair of Overseeded Bermudagrass
… plant growth regulators (PGRs), such as trinexapac-ethyl, may improve the traffic tolerance of "Patriot" and "Tifsport" hybrid berudagrasses (Cynodon dactylon var. dactylon x Cynodon transvaalensis). This study was designed to mimic the agronomic practices and traffic stresses experienced …

Evaluating methiozolin programs for golf putting greens and investigating potential modes of action
… via synthetic fertilizer with or without trinexapac-ethyl or biostimulant recovered 1 to 3 weeks more quickly than treatments that did not include additional fertility. Addition of the PGR trinexapac-ethyl inconsistently regulated speed of canopy recovery, both increasing and decreasing …

Competitive Effects of Perennial Ryegrass and Chewings Fescue on Bermudagrass Seed Establishment
… affect bermudagrass establishment. In 1996, trinexapac-ethyl slightly enhanced bermudagrass seed establishment, but the competitiveness of perennial ryegrass prohibited establishment success. During 1997, glyphosate was evaluated as a means of eliminating competition and increasing …

Technological Innovations for Mid-Atlantic Cropping Systems
… of rate and timing of the plant growth regulator trinexapac-ethyl to malting barley in Virginia. Plant growth regulators can help plants remain upright during strong winds, thereby preserving grain quality and yield. However, this study demonstrated that risks of plant injury also exist. …

Irrigation management effects on nitrate leaching and mowing requirements of tall fescue
… monthly applications of the growth regulator trinexapac-ethyl (TE). Data were collected on total mowings and visual turf quality. Soil moisture sensor-based irrigation resulted in water savings of 32 to 70% compared to frequency-based irrigation. Leaching levels did not exceed 0.6 mg L⁻¹ and …

Impact of Management Practices on Cold Tolerance of Ultradwarf Bermudagrass Putting Greens
… fungicide programming, core aeration, and trinexapac-ethyl (TE) on UDB cold tolerance, winter quality, and cold de-acclimation (CD). Our results indicate that the use of turf covers significantly increased UDB canopy and soil temperatures when air temperatures were below -3.9°C. Air gaps …

Evaluation of fine fescues as alternative golf course fairway turfgrasses
… the effect of the plant growth regulator trinexapac-ethyl on the performance of fine fescue mixtures when managed as a golf course fairway and identify fine fescue mixtures that perform well under traffic stress. The marginal effects summaries showed hard fescue [Festuca trachyphylla …

Managing Stress Tolerance on Warm-Season Putting Greens in the Transition Zone
… the treatment of the plant growth regulator, trinexapac-ethyl. The minimum daily light integral (DLI) was determined for both species and surface characteristics, including ball roll distance and surface firmness, were monitored. ‘Lazer’ zoysiagrass demonstrated superior shade-tolerance and …
