Abstract/Contents:"Purple nutsedge (Cyperus rotundus) is a problematic perennial weed in turfs in Arizona and Southern California. Mon 12000 (MANAGE) and Imazaquin (IMAGE) herbicides were evaluated for post emergence control of this weed on 25 year old stands of 100% purple nutsedge at the University of Arizona. Three applications of five treatments were made on June 29, August 9, and September 17, 1993. Plots were evaluated on nine dates for percent nutsedge control. Repeat applications of Mon 12000 at either (0.062 + 0.062 + 0.062), or (0.062 + 0.031 + 0.031) lbs ai/A had control levels not statistically different from each other, although the three applications at the high rate provided slightly better control/suppression on 2 out of 9 dates only. An initial application at 0.125 lbs ai/A produced high to moderate levels of control for up to 40 DAT. A late season applicaion at the 0.125 lb ai/A rate when preceded with no herbicide produced lower amounts of weed control in September and October. When allowed to grow without a herbicide treatment until August, the 0.125 lb ai/A rate reached a maximum of 56% control at 36 DAT. Image at 0.5 lb ai/A provided control generally equal to Mon 12000, being somewhat greater in mid season, and slightly less in September and October. Regrowth occurred in all treatments."
