Abstract/Contents:Growth retardants; mefluidide 2S, MBR 18337 2EC, ethephon 2S, and EL 72500 50WP and 1G; were applied to a Kentucky bluegrass turf to evaluate growth suppression and turf quality during the second year of application under low management conditions. EL 72500 50WP at 2.0 and 3.0 lb ai/A rate provided the best season-long combination of growth retardation and turf quality. Data indicated that mefluidide and MBR 18337 treated plots sustained loss of density in 1979 as corroborated by high weed infestation percentages in 1980. A mid-July trim mowing and application of fertilizer improved turf quality in EL 72500 WP and 1G and ethephon treatments. Poor turf quality ratings in mefluidide and MBR 18337 plots primarily reflect heavy crabgrass (Digitaria sp.) infestations. By October all plots displayed improved turf quality. Mefluidide and MBR treated plants exhibited highest percentages of leaves bearing Helminthosporium vagans leaf spot lesions. EL 72500 1G and 50WP had no deleterious effects upon rooting when applied twice yearly during two successive years to a Kentucky bluegrass turf.
