Vol. 40, No. 6, October 2005, p. 1902-1903.# of Pages: 2 Publishing Information: Alexandria, VA: American Society for Horticultural Science Keywords: TIC Keywords: Ethephon ; Gibberellic acid ; Agrostis stolonifera ; Golf greens ; Ball roll measurement ; Quality evaluation ; Growth regulators Abstract/Contents: "Plant growth regulators (PGRs) are often applied in combinations to reduce turf clippings, enhance turf quality, and suppress Poa annua L.; however, effects of PGR combinations on putting green ball roll distances have not been reported. Two field experiments were conducted on an 'L-93' creeping bentgrass (Agrostis stolonifera var. palustris Huds.) putting green in Clemson, S.C., to investigate effects of four PGRs with and without a subsequent application of ethephon at 3.8 kg路ha-1 a.i. 6 days after initial treatments. The PGRs initially applied included ethephon at 3.8 kg路ha-1 a.i., flurprimidol at 0.28 kg路ha-1 a.i., paclobutrazol at 0.28 kg路ha-1 a.i., and trinexapac-ethyl at 0.05 kg路ha-1 a.i.. Ball roll distances were enhanced 3% to 6% (4 to 8 cm) by exclusive flurprimidol, paclobutrazol, and trinexapac-ethyl treatments. The additional ethephon application reduced ball distances 2% to 9% (2 to 11 cm). Paclobutrazol and trinexapac-ethyl treated turf receiving the additional ethephon application had longer or similar ball roll distances to non-PGR treated turf. The additional ethephon treatment reduced turf quality to unacceptable levels 1 and 2 weeks after applications. However, bentgrass treated previously with trinexapac-ethyl and paclobutrazol had 8 to 16% higher visual quality following the additional ethephon treatment relative to non-PGR treated turf receiving the subsequent ethephon application. Overall, ethephon may have deleterious effects on monostand creeping bentgrass putting green quality and ball roll distances; however, applying ethephon with GA inhibitors could mitigate these adverse effects."
