Abstract/Contents:"Experiments were conducted during 1998-1999 and 1999-2000 to evaluate imazapyr for bermudagrass control. A single application of imazapyr at 0.25, 0.5 and 1.0 lb/ai/a alone and tank mixed with 1.5 lb/ai/a of glyphosate was made in May of each year. Additional treatments included a single May application of imazapyr + glufosinate at 0.5 + 1.0 lb/ai/a and three applications (May, July, September) of 1.5 lb/ai/a of glyphosate. Bermudagrass control was evaluated at one year after treatment. 'Meyer' zoysiagrass, was planted in treated areas after the 1998 study and 'Meyer' zoysiagrass, 'Cavalier' zoysiagrass, centipedegrass, 'Tifway' bermudagrass and St. Augustinegrass were planted in the treated areas the year after the 1999-2000 study. In both years, imazapyr at 1.0 lb/ai/a provided 100% control of bermudagrass one year after treatment while imazapyr + glyphosate at 1.0 + 1.5 lb/ai/a and three applications of glyphosate at 1.5 lb/ai/a provided >90% control. Mixing glufosinate with imazapyr significantly reduced (40 to 60%) bermudagrass control compared to the same rate of imazapyr alone. 'Meyer' zoysiagrass, 'Cavalier' zoysiagrass, centipedegrass, 'Tifway' bermudagrass, and St. Augustinegrass were successfully established in the areas treated with the 1.0 lb/ai/a rate of imazapyr the year after treatment. Zoysiagrass and St. Augustinegrass exhibited greater tolerance for imazapyr than bermudagrass and centipedegrass."
