| Abstract/Contents: | "Many golf courses overseed perennial ryegrass (Lolium perenne) in bermudagrass (Cynodon sp.) fairways to provide winter color. Plant growth regulators by suppressing late season growth of bermudagrass might allow for earlier and improved establishment of ryegrass when overseeded in bermudagrass maintained as a golf course fairway. Research was conducted on turf plots at Musgrove Mill Golf Club near Clinton, SC in 1993, 1994 and at Clemson University, Clemson, SC in 1995 to determine if plant growth regulators enhanced the establishment of ryegrass overseeded in hybrid bermudagrass fairways. The study consisted of a factorial arrangement of growth regulators and application dates in a randomized complete block design with four replicates. Plot size was 2 x 2 m. Growth regulators were applied using a CO₂ backpack sprayer. Individual plots were treated with single applications of either flurprimidol (1.7 kg/ha), paclobutrazol (0.28 kg/ha) or, trinexapac-ethyl (0.19 kg/ha) once in early September, mid-September, and early October. Perennial ryegrass was overseeded in Tifway '419' bermudagrass (Cynodon transvaalensis Burtt-Davy x C. dactylon (L.) Pers.) one week after application at 2.4 kg/acre in 1993, 1994, and 4.8 kg/acre in 1995. Plots were mowed twice a week at 1.3 cm. Ryegrass visual density, height, and bermudagrass injury were recorded. In 1993, percent visual density was severely reduced by flurprimidol (<30%) at 3 WAT when applied in early September. In 1994 and 1995 early September applications of flurprimidol only moderately reduced percent visual density of perennial ryegrass. In 1994 and 1995 flurprimidol applied in early September did not reduce percent visual density of perennial ryegrass 6 WAT. Early October applications of either flurprimidol or paclobutrazol reduced percent visual density of perennial ryegrass 4 WAT in 1993, 1994, and 1995. In 1995 flurprimidol applied in early September reduced perennial ryegrass height at 22 DAT but not by 30 DAT. In 1993 and 1994 mid-September applications of flurprimidol reduced ryegrass height at 6 WAT. Early October applications of flurprimidol reduced ryegrass height at 6 WAT. Early and mid-September applications of flurprimidol injured hybrid bermudagrass at 3 WAT for all three years. Regardless of application timing trinexapac-ethyl did not suppress ryegrass establishment nor injure bermudagrass by 4 WAT." |
