| Abstract/Contents: | "Plant growth regulation is becoming common practice along Virginia highway rights-of-way. The most common turfgrass planted in this situation is "KY 31" tallfescue (Festuca arundinacea Schreb.). Field studies on "KY 31" tall fescue were conducted in 1987 at three locations along Virginia highway rights-of-way. The efficacy of experimental plant growth regulators imazapyr plus imazethapyr (ACP 1911X), AC 247,466, and DPX L5300 plus mefluidide were compared against metsulfuron-methyl plus mefluidide and chlorsulfuron plus mefluidide as well as mowed and nonmowed controls. Multiple applications consisted of 1 application per year, 2 applications per year at 14 week intervals, 3 applications per year at 10 week intervals, and 4 applications per year at 6 week intervals when tall fescue was in mid to late boot stage. One application of AC 247,466 did not result in and phyotoxicity to the turf and resulted in a higher quality turf than standard plant growth regulators. ACP 1911X caused minimal phytotoxicity and also resulted in higher quality turf than standard plant growth regulators. DPX L5300 plus mefluidide varied in seedhead suppression between sights causing a lower quality turf. Two applications per year increased phytotoxicity for all treatments with metsulfurn-methyl plus mefluidide causing necrosis of the tall fescue. Four weeks later, the quality of ACP 1911X, AC 247,466, and DPX L5300 plus mefluidide increased as phytotoxicity decreased. Three applications per year resulted in even greater phytotoxicity. Tall fescue did not fully recover from this interval of treatments prior to first frost. Four applications per year resulted in variable results between sites." |
