| Abstract/Contents: | "`Tifway' hybrid bermudagrass [Cynodon transvaalensis Burtt-Davy x C. dactylon (L.) Pers.] and common bermudagrass [C. dactylon (L.) Pers.] are popular turfgrasses used throughout the southern USA. When both grasses are managed as a medium- to high-quality turf, frequent mowings are needed to limit vegetative growth and seedhead emergence. Plant growth regulators offer the potential to reduce the number of mowings needed by bermudagrass. Therefore, experiments were conducted on Tifway and common bermudagrasses to determine the effects of plant growth regulators on vegatative growth, seedhead suppression, and mowing requirements. Flurprimidol {alpha-(1-methylethyl)-alpha-[4-(trifluoro-methoxy)phenyl]-5 -pyrimidine-methanol}, paclobutrazol, {(+)-(R*R*)beta-[(4-chlorophenyl)methyl]-alpha-(1,1-dim ethylethyl)-1H1,2,4-trizole-1-ethanol}, and trinexapac-ethyl[4(cyclopropyl-alpha-hydroxy-methylene)-3,5- dioxocyclohexanecarboxylic acid ethyl ester] plant growth regulators were each applied at various rates in three applications at 4-wk intervals. When Tifway bermudagrass was treated initially with trinexapac-ethyl at 0.2 kg ha(-1), and followed by 0.1 kg ha(-1) at 4 and 8 wk, vegetative growth and seedheads were suppressed for 12 wk and the number of mowings were reduced by 70 and 67% during 1992 and 1993, respectively. However, the quality of Tifway bermudagrass was significantly lowered in plots treated with trinexapac-ethyl at this rate at four rating dates during 1992 and three rating dates during 1993, when compared with turfgrass treated initially at 0.1 kg ha(-1), and followed by 0.05 kg ha(-1) at 4 and 8 wk. Common bermudagrass was less affected by these treatments. Neither flurprimidol nor paclobutrazol applied in three applications during a 12-wk period provided consistent vegetative growth and seedhead suppression of common bermudagrass during 1992 and 1993." |
