Abstract/Contents:"Experiments were conducted during 1988 to determine the influence of formulation, mowing, irrigation timing following application, and application volume on control of purple nutsedge and/or wild garlic. Experiments were conducted at the Plant Science Research Center, Mississippi State University, Mississippi State. Unless noted, turfgrasses were maintained at a 3.8 cm height mowed weekly with a reel mower. P and K fertilizer was added as dictated by soil test with N applied at 96 kg/ha annually as sulfur coated urea applied in split applications in April and July. Purple nutsedge control with 560 g ai/ha imazaquin applied July 7, 1988 did not differ significantly when 1.5 cm water was applied by sprinkler irrigation at 1, 2, 4, 6, 8, 10, or 12 hours following treatment. Purple nutsedge control with 560 g/ha imazaquin did not differ at 1.3, 2.5, or 5.0 cm mowing height when applied in spray volumes of 47, 187, 935, or 1870 L/ha. Regrowth of wild garlic following application of 420 or 560 g/ha imazaquin was greater if mowed immediately prior to treatment or 2 weeks after treatment than if plots were mowed at 4 or 6 weeks after treatment. However, control 3 months after treatment was not influenced by mowing time. Granular imazaquin (27-3-3 fertilizer) provided less control of purple nutsedge, especially at lower rates. At 140, 280, 420, or 560 kg/ha imazaquin, purple nutsedge control with the granular formulation was delayed approximately 2 weeks compared to the sprayable formulation at equivalent rates. Seedhead suppression of common bermudagrass was significantly less 2 weeks after treatment with the granular formulation than in plots treated at the same rate with the sprayable formulation. Similar differences were noted in fresh weight of clippings at 2 weeks after treatment. However, these differences between formulations were no longer evident 4 weeks after treatment."
