Abstract/Contents:"Purple nutsedge is a persistent weed in lower elevation turfs in Arizona. Its high elongation rate, coarse leaf texture, and light green color are objectionable in turfgrass stands. This study was conducted to determine the effects of turfgrass cultivar, mowing height and imazaquin herbicide on purple nutsedge suppression over the 1988 and 1989 growing seasons. Nutsedge infestations were monitored after three applications in 1988 and 1989, totalling six applications, each at the 0.56 kg/ha rate. During both years, 'Midiron' bermuda was not as competitive as 'Tifway' bermudagrass when no herbicide was applied. 'Midiron' was influenced by mowing, allowing for 60 cm2 infestation levels at the low (1.9 cm) mowing height during midsummer of both years. With repeat applications, purple nutsedge was greatly reduced during the first yr (1988), and essentially eliminated in the more aggressive 'Tifway' turf after an early summer application in yr two (1989). Mowing height was not significant when the herbicide was applied. This data shows that both competitive (grass type and mowing height) and herbicide effects are effective in reducing purple nutsedge infestation levels in turfgrass stands under conditions of this test."
