Abstract/Contents:"Field and growth chamber studies were conducted to determine the effectiveness of glyphosate in controlling three perennial grasses, and its residual effects on germination and establishment of several turfgrass species. Glyphosate was applied at 2 lb/A on tall fescue, nimblewill, and quackgrass in September 1974 with tillage treatments (rototill) of no till and tillage 6, 24, 48, and 72 hr after treatment. The tall fescue was several years old and growing in sandy loam soil under turf conditions. The nimblewill was an old established sod while the quackgrass was in small grain stubble, both in silt loam soils. The nimblewill and quackgrass were 6 to 8 inches high but were clipped to 3 inches 2 days before spraying. Visual observations in November 1974 showed 100% control of nimblewill and tall fescue, while 95% quackgrass control was achieved. Stand counts in May 1975 showed 100% nimblewill control on all tillage treatments, while 95% quackgrass control was achieved. Stand counts in May 1975 showed 100% nimblewill control on all tillage treatments, and tall fescue with 99% control with no tillage and 100% with all other tillage treatments. Quackgrass control generally improved from 87% to 99% with increased delay in time of tillage following glyphosate application. In a Kentucky bluegrass establishment study, glyphosate was applied at 2 lb/A on October 9, 1974, to Kentucky bluegrass sod growing on sandy loam soil. Varying the type of tillage (dethatch vs. rototill) and seeding interval after glyphosate application showed maximum establishment in May 1975 when the sod was dethatched and overseeded immediately after glyphosate treatment. Rototilled treatments had very poor establishment. Growth chamber studies showed the rate of glyphosate (0 and 2 lb/A) and type of medium (sand, silty clay, ½ sand + ½ silty clay) did not affect percent germination of Manhattan ryegrass, Pennlawn red fescue, or Merion Kentucky bluegrass."
