| Abstract/Contents: | "Field tests were established throughout the southeastern United States during 1982 and 1983 to evaluate the efficacy of glyphosate [N-(phosphonomethyl) glycine] and sulfometuron methyl [Methyl 2-[[[[(4,6-dimethyl-2-pyrimidinyl) amino] - carbonyl] amino] sulfonyl] benzoate for bermudagrass (Cynodon dactylon) release on highway rights-of-way. Glyphosate rates of 0.63 to 0.84 kg AE/ha alone or rates of 0.31 to 0.43 kg AE/ha in combination with 0.05 to 0.07 kg AI/ha sulfometuron methyl provided broadspectrum control of winter annual grasses and broadleaf weeds in dormant bermudagrass turf. Treatments of glyphosate or sulfometuron methyl alone gave only partial control of tall fescue (Festuca arundinacea) at these rates while the combination provided full control. Greenup of bermudagrass was not adversely affected by dormant season treatments of the combination. Long-term control of rhizome johnsongrass (Sorghum halepense) was provided by glyphosate rates of 0.43 to 0.84 kg AE/ha applied at boot to head stage. Temporary discoloration and moderate injury to actively growing bermudagrass turf was observed in all treatments. Complete recovery of the turf occurred within sixty to ninety days. Combinations of glyphosate at 0.31 to 0.63 kg AE/ha and sulfometuron methyl at 0.05 to 0.07 kg AI/ha applied prior to johnsongrass seedhead emergence gave excellent initial control with some regrowth from rhizomatous rootstocks. Unacceptable bermudagrass injury occurred at the higher combination rates at locations where mowing or drought stressed the turf prior to or following treatments." |
