Abstract/Contents:"In September, 1987, a study evaluating seven individual species and five combinations (Table 1) was established on a roadside site in Tyrone, Blair County, in a median area on a closed portion of SR 220. The site was treated with 3 lb ae/acre glyphosate to kill existing vegetation, mowed, scarified with a tractor-mounted turf overseeder, and drop-seeded with 100 lb seed/acre. Individual plots were 12 by 30 ft, arranged in a randomized complete block design with three replications. No lime or fertilizer was applied to the study area. A selective broadleaf herbicide application of 2,4-D, MCPP, and dicamba at 1.22, 0.65, and 0.11 lb ae/acre respectively was applied June 17, 1988. The site was mowed the first time August 7, 1990. Visual ratings of percent turf and weed cover were taken July 3, and are reported in Table 1. The predominant weed was white sweetclover (Melilotus alba), which was 5 to 7 ft and in full bloom when rated. The sum of turf and weed coverage often exceeds 100 percent as two plant canopies were rated within each plot. Data for 'Tioga' deertongue grass is not reported as almost no plants were observed in the plots in 198. In subsequent years, coverage has increased to an average of 30 percent. The six treatments including hard or creeping red fescue provided excellent cover, and were significantly better than all other treatments. When combined with either hard or creeping red fescue, tall fescue was present only a isolated clumps, and perennial ryegrass was not observed. Turf-type and 'Kentucky-31' tall fescue provided similar, and acceptable, performance, and were virtually indistinguishable as the turf-type was as coarse textured as the 'Kentucky 31' under these conditions. Perennial ryegrass went through a significant decline between September 1989, and this rating, and remains only as stunted, isolated clumps, resulting in almost no turf cover in ryegrass-only plots, and only tall fescue in the combination plots. Canada bluegrass has established thin, but even stands which have low weed pressure despite the lack of turf density."
